林格模式改变监听广播接收器？ [英] Ringer mode change listener Broadcast receiver?

问题描述

AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE);

switch (am.getRingerMode()) {
case AudioManager.RINGER_MODE_SILENT:
Log.i("MyApp","Silent mode");
break;
case AudioManager.RINGER_MODE_VIBRATE:
Log.i("MyApp","Vibrate mode");
break;
case AudioManager.RINGER_MODE_NORMAL:
Log.i("MyApp","Normal mode");
break;
}

从code以上我可以得到振铃模式。我会liek做的就是听振铃模式的变化和调用一个函数。

From the code above I can get the ringer mode. What I would liek to do is listen the ringer mode changes and call a function.

我被告知的是，我可以注册AudioManager。 RINGER_MODE_CHANGED_ACTION和收听的BroadcastReceiver的onReceive方法的改变意图。这听起来很清楚。但是，我是新来的Andr​​oid和真的不知道怎么写。是否有任何人可以只写一张code和表现究竟如何它的工作原理，而不是说用这样或那样的:)谢谢

What I have been told is that I can register the AudioManager. RINGER_MODE_CHANGED_ACTION and listen the change intent in broadcastreceiver onReceive method. It sounds clear. But I am new to android and really dont know how to write it. Is there any one can just write a piece of code and show how exactly it works instead of saying use this or that :) Thank you

推荐答案

使用下面的code你的的onCreate（）方法内>活动或服务，你要处理的广播：

Use the following code inside the onCreate() method of your Activity or Service that you want to process the broadcast:

      BroadcastReceiver receiver=new BroadcastReceiver(){
          @Override
          public void onReceive(Context context, Intent intent) {
               //code...
          }
      };
      IntentFilter filter=new IntentFilter(
                      AudioManager.RINGER_MODE_CHANGED_ACTION);
      registerReceiver(receiver,filter);
