推荐答案

将这个code到您的按钮的onClick监听器。它创建了一个接收器，处理器和意图过滤器，设置你的接收机应进行注册和注册它的动作。不要'忘了注销其所有的工作都会做了。

Put this code to your button onClick listener. It creates a receiver, handler, and intent filter, sets the action your receiver should be registered for and register it. Dont' forget to unregister it after all the work will be done.

// this goes before onCreate()
    private static final String ACTION = "YOUR_ACTION_HERE";
/// in button listener:
    Handler mHandler = new Handler();
    BroadcastReceiver mIntentReceiver = new BroadcastReceiver() {
      @Override
      public void onReceive(Context context, Intent intent) {
        // Handle reciever
        String mAction = intent.getAction();

        if(mAction.equals(ACTION) {
          // Do your thing   
        }
    }
    IntentFilter intentToReceiveFilter = new IntentFilter();
    intentToReceiveFilter.addAction(ACTION);
    this.registerReceiver(mIntentReceiver, intentToReceiveFilter, null, mHandler);
