Question

经过长时间的搜索，我无法解决我的问题。

在我的应用中，我想用白名单静默控制来电号码。

这是使用的代码，有时它完美但不是每次都能正常工作。铃声模式已恢复，当我按下上或下音量控制时我可以控制它，但没有声音输出到设备。

手机响铃时是否可以更改振铃模式？我的测试是在S3 4.3

感谢您抽出时间帮助我。

Answer 1

许可：

<uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

代码：

// Disable ringtone & vibration
AudioManager am = (AudioManager) getBaseContext().getSystemService(Context.AUDIO_SERVICE);
int ringerMode = am.getRingerMode();
am.setRingerMode(AudioManager.RINGER_MODE_SILENT);

... doing something ...

// Restore ringtone settings after check
am.setRingerMode(ringerMode);

关闭来电的声音是随机的
