复制代码 代码如下:

private static int previousMuteMode = -1;

/**

* 来电静音

*

* @param context

*/

private void toggleRingerMute(Context context)

{

AudioManager am = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);

if (previousMuteMode == -1)

{

previousMuteMode = am.getRingerMode();

am.setRingerMode(0);

}

am.setRingerMode(previousMuteMode);

previousMuteMode = -1;

}
