Android 铃声和音量的获取程序

　　android 铃声和音量的获取程序

　　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
