+## 异步Diff & 原始DiffUtil.Callback
+用户可以直接使用`DiffUtil.Callback`，自己进行diff计算，将结果告知adapter即可。
+所以adapter并不关心diff计算过程，用户可以同步或是异步进行。
+使用如下方法：
+```java
+setNewDiffData(DiffUtil.DiffResult, List)}
+```
+例子：
+```java
+new Thread(new Runnable() {
+    @Override
+    public void run() {
+        final List<DiffUtilDemoEntity> newData = getNewList();
+        DiffDemoCallback callback = new DiffDemoCallback(newData);
+        final DiffUtil.DiffResult diffResult = DiffUtil.calculateDiff(callback, false);
+        runOnUiThread(new Runnable() {
+            @Override
+            public void run() {

+            }
