通过程序获取android系统手机的铃声和音量。同样，设置铃声和音量的方法也很简单！
- AudioManager mAudioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
//通话音量
- int max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_VOICE_CALL );
- int current = mAudioManager.getStreamVolume( AudioManager.STREAM_VOICE_CALL );
- Log.d("VIOCE_CALL", "max : " + max + " current : " + current);
//系统音量
- max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_SYSTEM );
- current = mAudioManager.getStreamVolume( AudioManager.STREAM_SYSTEM );
- Log.d("SYSTEM", "max : " + max + " current : " + current);
//铃声音量
- max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_RING );
- current = mAudioManager.getStreamVolume( AudioManager.STREAM_RING );
- Log.d("RING", "max : " + max + " current : " + current);
//音乐音量
- max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_MUSIC );
- current = mAudioManager.getStreamVolume( AudioManager.STREAM_MUSIC );
- Log.d("MUSIC", "max : " + max + " current : " + current);
//提示声音音量
- max = mAudioManager.getStreamMaxVolume( AudioManager.STREAM_ALARM );
- current = mAudioManager.getStreamVolume( AudioManager.STREAM_ALARM );
- Log.d("ALARM", "max : " + max + " current : " + current);
设置音量的方法也很简单，AudioManager提供了方法：
public void setStreamVolume(int streamType, int index, int flags)
其中 streamType 有内置的常量，去文档里面就可以看到
