# UTSActivityCallback
为了更好的对外暴露activity的方法，我们把activity里面包含的方法按照继承关系进行了分类，下面是分类标准
第一类：activity生命周期相关方法[UniActivityLifeCycleCallback](https://doc.dcloud.net.cn/uni-app-x/uts/utsactivitycallback.html#UniActivityLifeCycleCallback)\
比如 oncreate,ondestory 等\
第二类: 键盘事件相关方法[UniActivityKeyEventCallback](https://doc.dcloud.net.cn/uni-app-x/uts/utsactivitycallback.html#UniActivityKeyEventCallback)\
比如 onKeyDown,onKeyUp等\
第三类:window窗体的相关方法[UniActivityWindowCallback](https://doc.dcloud.net.cn/uni-app-x/uts/utsactivitycallback.html#UniActivityWindowCallback)\
比如onCreatePanelMenu，onWindowDismissed等\
第四类:activity本身自带的相关方法，不继承自其他类[UniActivityCallback](https://doc.dcloud.net.cn/uni-app-x/uts/utsactivitycallback.html#UniActivityCallback)\
比如onProvideAssistData等\
第五类：Component 组件相关方法[UniActivityComponentCallback](https://doc.dcloud.net.cn/uni-app-x/uts/utsactivitycallback.html#UniActivityComponentCallback)\
比如onTrimMemory等
并且上面的五个类都为IUniActivityCallback的实现类，我们在使用的时候可以传入具体的实现类，然后按照具体需求重写其中的某个方法，具体用法参考[示例](https://doc.dcloud.net.cn/uni-app-x/uts/utsactivitycallback.html#示例)

uvue代码
```vue
{{ text }}
点击注册activity 回调方法后，可以手动切换其他APP再返回，可在控制台和界面观察事件日志
{{ cbText }}
```

let callback : (eventLog : string) => void = (res) => { };
export function onCallbackChange(fn : (eventLog : string) => void) {
