android - Runnable 只运行一次

Question

我需要多次执行任务，直到满足特定条件。代码:

handler = new Handler();
runnableCode = new Runnable() {
   @Override
   public void run() {
       doThings();
   }
};
handler.postDelayed(runnableCode, 200);

方法做事:

private void doThings(){
    //conditions are met
    stopRunnable();

}

方法停止运行:

private void stopRunnable(){
    handler.removeCallbacks(runnableCode);
}

这样，doThings() 方法只执行一次。我应该怎么做？

谢谢

我建议你试试:

handler=new Handler();
runnableCode = new Runnable() {
    @Override
    public void run() {
    doThings();
    if(condition){
        handler.postDelayed(runnableCode, 200);
    }
    }
};
handler.postDelayed(runnableCode, 200);

方法停止运行:

private void stopRunnable(){
    handler.removeCallbacksAndMessages(null);
}
