android audioManager获取音量

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！

Java代码

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);

ps：

游戏过程中 只允许调整多媒体音量，而不允许调整通话音量。

Java代码

setVolumeControlStream(AudioManager.STREAM_MUSIC);
