我有一个PhoneReceiver类，它扩展BroadcastReceiver我设置手机的个人资料模式
沉默。
AudioManager manager = (AudioManager) context.getSystemService(Context.AUDIO_SERVICE);
manager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
当我显示信息日志时
Log.i("tag", "RingerMode: " + context.getRingerMode());
我在日志中得到"RingerMode: 0"。
问题是，手机会显示静音模式的图标，并在设置菜单中显示为静音。但是当有来电时，会播放铃声。它似乎发生在代码setRingerMode()被执行之后。据我所知，手机已正确设置为静音模式，但当有来电时，这完全被忽略。
我在Activity中也有相同的代码，当我从那里运行它时工作正常（接到电话时手机是静音的）。这让我相信它与接收器中执行的静音模式代码有关。
手机似乎陷入了忽略静音模式的状态。即使我卸载了我的应用程序，手机也会忽略静音模式。将手机设置为正常模式，然后从我的活动恢复为静音模式，可使手机再次正常工作。 我已经搜索了这种行为的原因了好几天，但我无法弄明白。
这是接收器类
