如何获取和设置android系统铃声和音量大小

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! 设置音量的方法也很简单，AudioManager提供了方法: publicvoidsetStreamVolume(intstreamType,intindex,intflags)其中streamType有内置的常量，去文档里面就可以看到。 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。 setVolumeControlStream(AudioManager.STREAM_MUSIC); 长时间不动，不允许黑屏，View.setKeepScreenOn(true); 估计manifest文件中需要注册权限吧
