欢迎提出更好的思路大家一起讨论。
## 第一种写法:直接 Post
```java
myHandler.post(mLoadingRunnable);
```
## 第二种写法:直接 PostDelay 300ms.
```java
myHandler.postDelayed(mLoadingRunnable, DELAY_TIME);
```
## 第三种写法: 优化的 PostDelay ，两次进行 Delay Load
```java
getWindow().getDecorView().post(new Runnable() {
@Override
public void run() {
myHandler.post(mLoadingRunnable);
}
});
```
## 第四种写法（推荐）：使用 IdleHandler 进行 Delay Load
```java
// 利用 IdleHandler
MessageQueue.IdleHandler idleHandler = new MessageQueue.IdleHandler() {
@Override
public boolean queueIdle() {
updateText();
return false;
}
};
Looper.myQueue().addIdleHandler(idleHandler);
```
