本文实例讲述了android编程获取和设置系统铃声和音量大小的方法。分享给大家供大家参考,具体如下:

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:

public voidsetStreamVolume(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);
