android - 如何通过音频管理器以编程方式将振动模式更改为响铃

Question

我正在制作应用程序，如果用户发送带有特定关键字的短信，电话模式将从静音模式变为振铃模式。该应用程序主要在用户在家中某处丢失手机并处于静音模式时工作。我的主要问题是如何通过音频管理器更改电话模式？

Answer 1

使用将静音模式设置为正常模式AudioManager

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

switch (am.getRingerMode()) {   
    case AudioManager.RINGER_MODE_SILENT:   
        Log.i("MyApp","Silent mode");
        am.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
        break;   
}  

Answer 2

AudioManager manager = (AudioManager) getContext().getSystemService(AUDIO_SERVICE);
manager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);

Answer 3

尝试这个：

AudioManager audioManager = (AudioManager) getSystemService(AUDIO_SERVICE);
audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);

Answer 4

使其适用于棉花糖及以上的安卓设备（API 23）

1. 在AndroidManifest.xml定义ACCESS_NOTIFICATION_POLICY权限

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

2. 如果未授予，请在您的onResume/onCreate函数中请求许可

   @Override
   protected void onResume() {
       super.onResume();
       NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
       //Check if the phone is running Marshmallow or above
       if (Build.VERSION.SDK_INT>=Build.VERSION_CODES.M) {
           //If the permission is not granted, launch an inbuilt activity to grant permission
           if (!nm.isNotificationPolicyAccessGranted()) {
               startActivity(new Intent(Settings.ACTION_NOTIFICATION_POLICY_ACCESS_SETTINGS));
           }
       }
   }
   

3. 最后改变铃声模式调用这个方法

   public void setRingerMode(Context context,int mode){
           /*
           * mode variable value can be:
           * AudioManager.RINGER_MODE_SILENT
           * AudioManager.RINGER_MODE_NORMAL
           * AudioManager.RINGER_MODE_VIBRATE
           */
           NotificationManager nm = (NotificationManager)context.getSystemService(NOTIFICATION_SERVICE);
           AudioManager audioManager = (AudioManager)context.getSystemService(AUDIO_SERVICE);
           if(Build.VERSION.SDK_INT>=Build.VERSION_CODES.M && nm.isNotificationPolicyAccessGranted())
               audioManager.setRingerMode(mode);
       }
