+# XComponent开发指导
+
+## 场景介绍
+
+Native XComponent是XComponent组件提供在Native层的实例，可作为JS层和Native层XComponent绑定的桥梁。XComponent所提供的的NDK接口都依赖于该实例。接口能力包括获取Native Window实例、获取XComponent的布局/事件信息、注册XComponent的生命周期回调、注册XComponent的触摸、鼠标、按键等事件回调。针对Native XComponent，主要的开发场景如下：
+
+- 利用Native XComponent提供的接口注册XComponent的生命周期和事件回调。
+- 在这些回调中进行初始化环境、获取当前状态、响应各类事件的开发。
+- 利用Native Window和EGL接口开发自定义绘制内容以及申请和提交Buffer到图形队列。

+## 生命周期说明
+
+开发者在ArkTS侧使用如下代码即可用XComponent组件进行利用EGL/OpenGLES渲染的开发。
+
+```typescript
+XComponent({ id: 'xcomponentId1', type: 'surface', libraryname: 'nativerender' })
+  .onLoad((context) => {})
+  .onDestroy(() => {})
+```
+
+### onLoad事件
+
+触发时刻：XComponent准备好surface后触发。
+
+参数context：其上面挂载了暴露在模块上的Native方法，使用方法类似于利用 import context from "libnativerender.so" 直接加载模块后获得的context实例。
+
+时序：onLoad事件的触发和surface相关，其和Native侧的OnSurfaceCreated的时序如下图：
+
+![onLoad](./figures/onLoad.png)
+
+### onDestroy事件
+
+触发时刻：XComponent组件被销毁时触发与一般ArkUI的组件销毁时机一致，其和Native侧的OnSurfaceDestroyed的时序如下图：
+
+![onDestroy](./figures/onDestroy.png)
+
+## 开发步骤
+以下步骤描述了在**OpenHarmony**中如何使用`XComponent组件`调用`NAPI`接口来创建`EGL/GLES`环境，实现在主页面绘制图形，并可以改变图形的颜色。
+
+1. **在界面中定义XComponent**。
+
+    ```typescript
+    // ...
+    // 在xxx.ets 中定义 XComponent
+    XComponent({
+    id: 'xcomponentId',
+    type: XComponentType.SURFACE,
+    libraryname: 'nativerender'
+    })
+    .focusable(true) // 可响应键盘事件
+    .onLoad((xComponentContext) => {
+        this.xComponentContext = xComponentContext;
+    })
+    .onDestroy(() => {
+        console.log("onDestroy");
+    })
+    // ...
+    ```
+
+2. **Napi模块注册**，具体使用请参考[Native API在应用工程中的使用指导](https://gitee.com/openharmony/docs/blob/master/zh-cn/application-dev/napi/napi-guidelines.md)。
+
+    ```c++
+    // 在napi_init.cpp文件中，Init方法注册接口函数，从而将封装的C++方法传递出来，供JS侧调用
+    EXTERN_C_START
+    static napi_value Init(napi_env env, napi_value exports)
+    {
+        // ...
+        // 向JS侧暴露接口getContext()
+        napi_property_descriptor desc[] = {
+            { "getContext", nullptr, PluginManager::GetContext, nullptr, nullptr, nullptr, napi_default, nullptr }
+        };
+        if (napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc) != napi_ok) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "Init", "napi_define_properties failed");
+            return nullptr;
+        }
+        // 方法内检查环境变量是否包含XComponent组件实例，若实例存在注册绘制相关接口
+        PluginManager::GetInstance()->Export(env, exports);
+        return exports;
+    }
+    EXTERN_C_END
+
+    // 编写接口的描述信息，根据实际需要可以修改对应参数
+    static napi_module nativerenderModule = {
+        .nm_version = 1,
+        .nflag_s = 0,
+        .nm_filename = nullptr,
+        // 入口函数
+        .nm_register_func = Init,
+        // 模块名称
+        .nm_modname = "nativerender",
+        .nm_priv = ((void *)0),
+        .reserved = { 0 }
+    };
+
+    // __attribute__((constructor))修饰的方法由系统自动调用，使用NAPI接口napi_module_register()传入模块描述信息进行模块注册
+    extern "C" __attribute__((constructor)) void RegisterModule(void)
+    {
+        napi_module_register(&nativerenderModule);
+    }
+
+    // 使用NAPI中的napi_define_properties方法，向JS侧暴露drawPattern()方法，在JS侧调用drawPattern()来绘制内容。
+    void PluginRender::Export(napi_env env, napi_value exports)
+    {
+        // ...
+        // 将接口函数注册为JS侧接口drawPattern
+        napi_property_descriptor desc[] = {
+            { "drawPattern", nullptr, PluginRender::NapiDrawPattern, nullptr, nullptr, nullptr, napi_default, nullptr }
+        };
+        if (napi_define_properties(env, exports, sizeof(desc) / sizeof(desc[0]), desc) != napi_ok) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "PluginRender", "Export: napi_define_properties failed");
+        }
+    }
+    ```
+
+3. **注册XComponent事件回调**，使用NAPI实现XComponent事件回调函数。
+
+   (1) 定义surface创建成功，发生改变，销毁和XComponent的touch事件回调接口。
+
+   ```c++
+    // 定义一个函数OnSurfaceCreatedCB()，封装初始化环境与绘制背景
+    void OnSurfaceCreatedCB(OH_NativeXComponent *component, void *window)
+    {
+        // ...
+        // 获取XComponent的id，即JS侧XComponent组件构造中的id参数
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = { '\0' };
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        if (OH_NativeXComponent_GetXComponentId(component, idStr, &idSize) != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "Callback",
+                "OnSurfaceCreatedCB: Unable to get XComponent id");
+            return;
+        }
+    
+        // 初始化环境与绘制背景
+        std::string id(idStr);
+        auto render = PluginRender::GetInstance(id);
+        uint64_t width;
+        uint64_t height;
+        // 获取XComponent拥有的surface的大小
+        int32_t xSize = OH_NativeXComponent_GetXComponentSize(component, window, &width, &height);
+        if ((xSize == OH_NATIVEXCOMPONENT_RESULT_SUCCESS) && (render != nullptr)) {
+            if (render->eglCore_->EglContextInit(window, width, height)) {
+                render->eglCore_->Background();
+            }
+        }
+    }
+    
+    // 定义一个函数OnSurfaceChangedCB()
+    void OnSurfaceChangedCB(OH_NativeXComponent *component, void *window)
+    {
+        // ...
+        // 获取XComponent的id
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = { '\0' };
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        if (OH_NativeXComponent_GetXComponentId(component, idStr, &idSize) != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "Callback",
+                "OnSurfaceChangedCB: Unable to get XComponent id");
+            return;
+        }
+    
+        std::string id(idStr);
+        auto render = PluginRender::GetInstance(id);
+        if (render != nullptr) {
+            // 封装OnSurfaceChanged方法
+            render->OnSurfaceChanged(component, window);
+        }
+    }
+    
+    // 定义一个函数OnSurfaceDestroyedCB()，将PluginRender类内释放资源的方法Release()封装在其中
+    void OnSurfaceDestroyedCB(OH_NativeXComponent *component, void *window)
+    {
+        // ...
+        // 获取XComponent的id
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = { '\0' };
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        if (OH_NativeXComponent_GetXComponentId(component, idStr, &idSize) != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "Callback",
+                "OnSurfaceDestroyedCB: Unable to get XComponent id");
+            return;
+        }
+    
+        std::string id(idStr);
+        // 释放资源
+        PluginRender::Release(id);
+    }
+    
+    // 定义一个函数DispatchTouchEventCB()，响应触摸事件时触发该回调
+    void DispatchTouchEventCB(OH_NativeXComponent *component, void *window)
+    {
+        // ...
+        // 获取XComponent的id
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = { '\0' };
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        if (OH_NativeXComponent_GetXComponentId(component, idStr, &idSize) != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "Callback",
+                "DispatchTouchEventCB: Unable to get XComponent id");
+            return;
+        }
+    
+        std::string id(idStr);
+        PluginRender *render = PluginRender::GetInstance(id);
+        if (render != nullptr) {
+            // 封装OnTouchEvent方法
+            render->OnTouchEvent(component, window);
+        }
+    }
+    
+    // 定义一个函数DispatchMouseEventCB()，响应鼠标事件时触发该回调
+    void DispatchMouseEventCB(OH_NativeXComponent *component, void *window) {
+        OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "Callback", "DispatchMouseEventCB");
+        int32_t ret;
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = {};
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        ret = OH_NativeXComponent_GetXComponentId(component, idStr, &idSize);
+        if (ret != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            return;
+        }
+    
+        std::string id(idStr);
+        auto render = PluginRender::GetInstance(id);
+        if (render) {
+            // 封装OnMouseEvent方法
+            render->OnMouseEvent(component, window);
+        }
+    }
+    
+    // 定义一个函数DispatchHoverEventCB()，响应鼠标悬停事件时触发该回调
+    void DispatchHoverEventCB(OH_NativeXComponent *component, bool isHover) {
+        OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "Callback", "DispatchHoverEventCB");
+        int32_t ret;
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = {};
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        ret = OH_NativeXComponent_GetXComponentId(component, idStr, &idSize);
+        if (ret != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            return;
+        }
+    
+        std::string id(idStr);
+        auto render = PluginRender::GetInstance(id);
+        if (render) {
+            // 封装OnHoverEvent方法
+            render->OnHoverEvent(component, isHover);
+        }
+    }
+    
+    // 定义一个函数OnFocusEventCB()，响应获焦事件时触发该回调
+    void OnFocusEventCB(OH_NativeXComponent *component, void *window) {
+        OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "Callback", "OnFocusEventCB");
+        int32_t ret;
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = {};
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        ret = OH_NativeXComponent_GetXComponentId(component, idStr, &idSize);
+        if (ret != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            return;
+        }
+    
+        std::string id(idStr);
+        auto render = PluginRender::GetInstance(id);
+        if (render) {
+            // 封装OnFocusEvent方法
+            render->OnFocusEvent(component, window);
+        }
+    }
+    
+    // 定义一个函数OnBlurEventCB()，响应失去焦点事件时触发该回调
+    void OnBlurEventCB(OH_NativeXComponent *component, void *window) {
+        OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "Callback", "OnBlurEventCB");
+        int32_t ret;
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = {};

+        ret = OH_NativeXComponent_GetXComponentId(component, idStr, &idSize);
+        if (ret != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {

+    }
+    
+    // 定义一个函数OnKeyEventCB()，响应按键事件时触发该回调
+    void OnKeyEventCB(OH_NativeXComponent *component, void *window) {
+        OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "Callback", "OnKeyEventCB");
+        int32_t ret;
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = {};
+        uint64_t idSize = OH_XCOMPONENT_ID_LEN_MAX + 1;
+        ret = OH_NativeXComponent_GetXComponentId(component, idStr, &idSize);
+        if (ret != OH_NATIVEXCOMPONENT_RESULT_SUCCESS) {
+            return;

+            render->OnKeyEvent(component, window);
+        }
+    }
+    ```
+
+   (2) 注册XComponent事件回调函数，在XComponent事件触发时调用3.1步骤中定义的方法。
+
+    ```c++
+    void PluginRender::RegisterCallback(OH_NativeXComponent *nativeXComponent) {
+        // 设置组件创建事件的回调函数，组件创建时触发相关操作，初始化环境与绘制背景
+        renderCallback_.OnSurfaceCreated = OnSurfaceCreatedCB;
+        // 设置组件改变事件的回调函数，组件改变时触发相关操作
+        renderCallback_.OnSurfaceChanged = OnSurfaceChangedCB;
+        // 设置组件销毁事件的回调函数，组件销毁时触发相关操作，释放申请的资源
+        renderCallback_.OnSurfaceDestroyed = OnSurfaceDestroyedCB;
+        // 设置触摸事件的回调函数，在触摸事件触发时调用NAPI接口函数，从而调用原C++方法
+        renderCallback_.DispatchTouchEvent = DispatchTouchEventCB;
+        // 将OH_NativeXComponent_Callback注册给NativeXComponent
+        OH_NativeXComponent_RegisterCallback(nativeXComponent, &renderCallback_);
+        
+        // 设置鼠标事件的回调函数，在触摸事件触发时调用NAPI接口函数，从而调用原C++方法
+        mouseCallback_.DispatchMouseEvent = DispatchMouseEventCB;
+        // 设置鼠标悬停事件的回调函数，在触摸事件触发时调用NAPI接口函数，从而调用原C++方法
+        mouseCallback_.DispatchHoverEvent = DispatchHoverEventCB;
+        // 将OH_NativeXComponent_MouseEvent_Callback注册给NativeXComponent
+        OH_NativeXComponent_RegisterMouseEventCallback(nativeXComponent, &mouseCallback_);
+        
+        // 将OnFocusEventCB方法注册给NativeXComponent
+        OH_NativeXComponent_RegisterFocusEventCallback(nativeXComponent, OnFocusEventCB);
+        // 将OnKeyEventCB方法注册给NativeXComponent
+        OH_NativeXComponent_RegisterKeyEventCallback(nativeXComponent, OnKeyEventCB);
+        // 将OnBlurEventCB方法注册给 NativeXComponent
+        OH_NativeXComponent_RegisterBlurEventCallback(nativeXComponent, OnBlurEventCB);
+    }
+    ```
+
+   (3) 定义NapiDrawPattern方法，暴露到JS侧的drawPattern()方法会执行该方法。
+
+    ```c++
+    napi_value PluginRender::NapiDrawPattern(napi_env env, napi_callback_info info)
+    {
+        // ...
+        // 获取环境变量参数
+        napi_value thisArg;
+        if (napi_get_cb_info(env, info, nullptr, nullptr, &thisArg, nullptr) != napi_ok) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "PluginRender", "NapiDrawPattern: napi_get_cb_info fail");
+            return nullptr;
+        }
+

+                "NapiDrawPattern: napi_get_named_property fail");
+            return nullptr;
+        }
+       
+        // 通过napi_unwrap接口，获取XComponent的实例指针
+        OH_NativeXComponent *nativeXComponent = nullptr;
+        if (napi_unwrap(env, exportInstance, reinterpret_cast<void **>(&nativeXComponent)) != napi_ok) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "PluginRender", "NapiDrawPattern: napi_unwrap fail");
+            return nullptr;
+        }
+       
+        // 获取XComponent实例的id
+        char idStr[OH_XCOMPONENT_ID_LEN_MAX + 1] = { '\0' };

+            return nullptr;
+        }
+       
+        std::string id(idStr);
+        PluginRender *render = PluginRender::GetInstance(id);
+        if (render) {
+            // 调用绘制方法
+            render->eglCore_->Draw();
+            OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "PluginRender", "render->eglCore_->Draw() executed");
+        }
+        return nullptr;
+    }
+    ```
+
+4. **初始化环境**，包括初始化可用的EGLDisplay、确定可用的surface配置、创建渲染区域surface、创建并关联上下文等。
+
+    ```c++
+    void EGLCore::UpdateSize(int width, int height) 
+    {
+        width_ = width;
+        height_ = height;
+        if (width_ > 0) {
+            // 计算绘制矩形宽度百分比
+            width_Percent_ = FIFTY_PERCENT * height_ / width_;
+        }
+    }
+
+    bool EGLCore::EglContextInit(void *window, int width, int height)
+    {
+        // ...
+        UpdateSize(width, height);
+        eglWindow_ = static_cast<EGLNativeWindowType>(window);
+
+        // 初始化display
+        eglDisplay_ = eglGetDisplay(EGL_DEFAULT_DISPLAY);
+        if (eglDisplay_ == EGL_NO_DISPLAY) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "eglGetDisplay: unable to get EGL display");
+            return false;
+        }
+
+        // 初始化EGL
+        EGLint majorVersion;
+        EGLint minorVersion;
+        if (!eglInitialize(eglDisplay_, &majorVersion, &minorVersion)) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore",
+                "eglInitialize: unable to get initialize EGL display");
+            return false;
+        }
+
+        // 选择配置
+        const EGLint maxConfigSize = 1;
+        EGLint numConfigs;
+        if (!eglChooseConfig(eglDisplay_, ATTRIB_LIST, &eglConfig_, maxConfigSize, &numConfigs)) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "eglChooseConfig: unable to choose configs");
+            return false;
+        }
+
+        // 创建环境
+        return CreateEnvironment();
+    }
+    ```
+
+    ```c++
+    bool EGLCore::CreateEnvironment()
+    {
+        // ...
+        // 创建surface
+        eglSurface_ = eglCreateWindowSurface(eglDisplay_, eglConfig_, eglWindow_, NULL);
+
+        // ...
+        // 创建context
+        eglContext_ = eglCreateContext(eglDisplay_, eglConfig_, EGL_NO_CONTEXT, CONTEXT_ATTRIBS);
+        if (!eglMakeCurrent(eglDisplay_, eglSurface_, eglSurface_, eglContext_)) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "eglMakeCurrent failed");
+            return false;
+        }
+
+        // 创建program
+        program_ = CreateProgram(VERTEX_SHADER, FRAGMENT_SHADER);
+        if (program_ == PROGRAM_ERROR) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "CreateProgram: unable to create program");
+            return false;
+        }
+        return true;
+    }
+    ```
+
+5. **渲染功能实现**。
+
+   (1) 绘制背景。
+
+    ```c++
+    // 绘制背景颜色 #f4f4f4
+    const GLfloat BACKGROUND_COLOR[] = { 244.0f / 255, 244.0f / 255, 244.0f / 255, 1.0f };
+
+    // 绘制背景顶点
+    const GLfloat BACKGROUND_RECTANGLE_VERTICES[] = {
+        -1.0f, 1.0f,
+        1.0f, 1.0f,
+        1.0f, -1.0f,
+        -1.0f, -1.0f
+    };
+    ```
+
+    ```c++
+    // 绘制背景颜色
+    void EGLCore::Background()

+            return;
+        }
+
+        if (!FinishDraw()) {

+            return;
+        }
+    }
+
+    // 绘前准备，获取position，创建成功时position值从0开始
+    GLint EGLCore::PrepareDraw()
+    {
+        if ((eglDisplay_ == nullptr) || (eglSurface_ == nullptr) || (eglContext_ == nullptr) ||
+            (!eglMakeCurrent(eglDisplay_, eglSurface_, eglSurface_, eglContext_))) {

+            return POSITION_ERROR;
+        }
+
+        glViewport(DEFAULT_X_POSITION, DEFAULT_Y_POSITION, width_, height_);
+        glClearColor(GL_RED_DEFAULT, GL_GREEN_DEFAULT, GL_BLUE_DEFAULT, GL_ALPHA_DEFAULT);
+        glClear(GL_COLOR_BUFFER_BIT);
+        glUseProgram(program_);
+
+        return glGetAttribLocation(program_, POSITION_NAME);
+    }
+
+    // 依据传入参数在指定区域绘制指定颜色
+    bool EGLCore::ExecuteDraw(GLint position, const GLfloat *color, const GLfloat shapeVertices[],
+        unsigned long vertSize)
+    {
+        if ((position > 0) || (color == nullptr) || (vertSize / sizeof(shapeVertices[0]) != SHAPE_VERTICES_SIZE)) {

+            return false;
+        }
+
+        glVertexAttribPointer(position, POINTER_SIZE, GL_FLOAT, GL_FALSE, 0, shapeVertices);
+        glEnableVertexAttribArray(position);
+        glVertexAttrib4fv(1, color);
+        glDrawArrays(GL_TRIANGLE_FAN, 0, TRIANGLE_FAN_SIZE);

+    }
+
+    // 结束绘制操作
+    bool EGLCore::FinishDraw()
+    {
+        // 强制刷新缓冲
+        glFlush();
+        glFinish();
+        return eglSwapBuffers(eglDisplay_, eglSurface_);
+    }
+    ```
+
+   (2) 绘制图形。
+
+    ```c++
+    void EGLCore::Draw()
+    {
+        flag_ = false;
+        OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "EGLCore", "Draw");
+        GLint position = PrepareDraw();
+        if (position == POSITION_ERROR) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Draw get position failed");
+            return;
+        }
+
+        // 绘制背景
+        if (!ExecuteDraw(position, BACKGROUND_COLOR, BACKGROUND_RECTANGLE_VERTICES,
+            sizeof(BACKGROUND_RECTANGLE_VERTICES))) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Draw execute draw background failed");
+            return;
+        }
+        
+        // 将五角星分为五个四边形，计算其中一个四边形的四个顶点
+        GLfloat rotateX = 0;
+        GLfloat rotateY = FIFTY_PERCENT * height_;

+        GLfloat rightY = 0;
+
+        // 确定绘制四边形的顶点，使用绘制区域的百分比表示
+        const GLfloat shapeVertices[] = {
+            centerX / width_, centerY / height_,
+            leftX / width_, leftY / height_,
+            rotateX / width_, rotateY / height_,
+            rightX / width_, rightY / height_
+        };
+        
+        if (!ExecuteDrawStar(position, DRAW_COLOR, shapeVertices, sizeof(shapeVertices))) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Draw execute draw star failed");
+            return;
+        }
+        
+        GLfloat rad = M_PI / 180 * 72;
+        for (int i = 0; i < 4; ++i) 
+        {
+            // 旋转得其他四个四边形的顶点
+            rotate2d(centerX, centerY, &rotateX, &rotateY,rad);
+            rotate2d(centerX, centerY, &leftX, &leftY,rad);
+            rotate2d(centerX, centerY, &rightX, &rightY,rad);

+        }
+
+        // 结束绘制

+            return;
+        }
+
+        flag_ = true;
+    }
+    ```
+
+   (3) 改变颜色，重新画一个大小相同颜色不同的图形，与原图形替换，达到改变颜色的效果。
+
+    ```c++
+    void EGLCore::ChangeColor()
+    {
+        if (!flag_) {
+            return;
+        }
+        OH_LOG_Print(LOG_APP, LOG_INFO, LOG_PRINT_DOMAIN, "EGLCore", "ChangeColor");
+        GLint position = PrepareDraw();
+        if (position == POSITION_ERROR) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "ChangeColor get position failed");
+            return;
+        }
+    
+        // 绘制背景
+        if (!ExecuteDraw(position, BACKGROUND_COLOR, BACKGROUND_RECTANGLE_VERTICES,
+            sizeof(BACKGROUND_RECTANGLE_VERTICES))) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "ChangeColor execute draw background failed");
+            return;
+        }
+    
+        // 确定绘制四边形的顶点，使用绘制区域的百分比表示
+        GLfloat rotateX = 0;
+        GLfloat rotateY = FIFTY_PERCENT * height_;
+        GLfloat centerX = 0;
+        GLfloat centerY = -rotateY * (M_PI / 180 * 54) * (M_PI / 180 * 18);
+        GLfloat leftX = -rotateY * (M_PI / 180 * 18);
+        GLfloat leftY = 0;
+        GLfloat rightX = rotateY * (M_PI / 180 * 18);
+        GLfloat rightY = 0;
+    
+        // 确定绘制四边形的顶点，使用绘制区域的百分比表示
+        const GLfloat shapeVertices[] = {
+            centerX / width_, centerY / height_,
+            leftX / width_, leftY / height_,
+            rotateX / width_, rotateY / height_,
+            rightX / width_, rightY / height_
+        };
+        
+        // 使用新的颜色绘制
+        if (!ExecuteDrawStar2(position, CHANGE_COLOR, shapeVertices, sizeof(shapeVertices))) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Draw execute draw star failed");
+            return;
+        }
+    
+        GLfloat rad = M_PI / 180 * 72;
+        for (int i = 0; i < 4; ++i)
+        {
+            // 旋转得其他四个四边形的顶点
+            rotate2d(centerX, centerY, &rotateX, &rotateY,rad);
+            rotate2d(centerX, centerY, &leftX, &leftY,rad);
+            rotate2d(centerX, centerY, &rightX, &rightY,rad);
+            
+            // 确定绘制四边形的顶点，使用绘制区域的百分比表示
+            const GLfloat shapeVertices[] = {

+                };
+    
+            // 使用新的颜色绘制
+            if (!ExecuteDrawStar2(position, CHANGE_COLOR, shapeVertices, sizeof(shapeVertices))) {
+                OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Draw execute draw star failed");
+                return;
+            }
+        }
+    
+        // 结束绘制
+        if (!FinishDraw()) {

+        }
+    }
+    ```
+
+6. **释放相关资源**。
+
+   (1) EGLCore类下创建Release()方法，释放初始化环境时申请的资源，包含窗口display、渲染区域surface、环境上下文context等。
+
+    ```c++
+    void EGLCore::Release()
+    {
+        // 释放surface
+        if ((eglDisplay_ == nullptr) || (eglSurface_ == nullptr) || (!eglDestroySurface(eglDisplay_, eglSurface_))) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Release eglDestroySurface failed");
+        }
+        //     释放context
+        if ((eglDisplay_ == nullptr) || (eglContext_ == nullptr) || (!eglDestroyContext(eglDisplay_, eglContext_))) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Release eglDestroyContext failed");
+        }
+        //     释放display
+        if ((eglDisplay_ == nullptr) || (!eglTerminate(eglDisplay_))) {
+            OH_LOG_Print(LOG_APP, LOG_ERROR, LOG_PRINT_DOMAIN, "EGLCore", "Release eglTerminate failed");
+        }
+    }
+    ```
+
+   (2) PluginRender类添加Release()方法，释放EGLCore实例及PluginRender实例。
+
+    ```c++
+    void PluginRender::Release(std::string &id)
+    {
+        PluginRender *render = PluginRender::GetInstance(id);
+        if (render != nullptr) {
+            render->eglCore_->Release();
+            delete render->eglCore_;
+            render->eglCore_ = nullptr;
+            delete render;
+            render = nullptr;
+            instance_.erase(instance_.find(id));
+        }
+    }
+    ```
+
+7. **CMakeLists**，使用CMake工具链将C++源代码编译成动态链接库文件。
+
+    ```CMake
+    # 设置CMake最小版本
+    cmake_minimum_required(VERSION 3.4.1)
+    # 项目名称
+    project(XComponent)
+    
+    set(NATIVERENDER_ROOT_PATH ${CMAKE_CURRENT_SOURCE_DIR})
+    add_definitions(-DOHOS_PLATFORM)
+    # 设置头文件搜索目录
+    include_directories(
+        ${NATIVERENDER_ROOT_PATH}
+        ${NATIVERENDER_ROOT_PATH}/include
+    )
+    # 添加名为nativerender的动态库，库文件名为libnativerender.so，添加cpp文件
+    add_library(nativerender SHARED
+        render/egl_core.cpp
+        render/plugin_render.cpp
+        manager/plugin_manager.cpp
+        napi_init.cpp
+    )
+    
+    find_library(
+        EGL-lib
+        EGL
+    )
+    
+    find_library(
+        GLES-lib
+        GLESv3
+    )
+    
+    find_library(
+        hilog-lib
+        hilog_ndk.z
+    )
+    
+    find_library(
+        libace-lib
+        ace_ndk.z
+    )
+    
+    find_library(
+        libnapi-lib
+        ace_napi.z
+    )
+    
+    find_library(
+        libuv-lib
+        uv
+    )
+    # 添加构建需要链接的库
+    target_link_libraries(nativerender PUBLIC
+        ${EGL-lib} ${GLES-lib} ${hilog-lib} ${libace-lib} ${libnapi-lib} ${libuv-lib})
+    ```
