推荐答案

在活动"中使用处理程序来延迟事件，例如在您的情况下启动媒体播放器:

Use a Handler in your Activity to delay events such as starting the mediaplayer in your case:

private RefreshHandler mRedrawHandler = new RefreshHandler(); 
 private RefreshHandler mRedrawHandler = new RefreshHandler(); 

     class RefreshHandler extends Handler {  
            @Override  
            public void handleMessage(Message msg) {  
             MyActivity.startMusic();  
            }  

            public void sleep(long delayMillis) {  
              this.removeMessages(0);  
              sendMessageDelayed(obtainMessage(0), delayMillis);  
            }  
          };  

在按钮的onClick中，调用mRedrawHandler.sleep(5000);，startMusic()是您开始播放音乐的方法.

In onClick of button, call mRedrawHandler.sleep(5000); , startMusic() is a method where you are starting the mucsic playback.
