振铃模式更改监听器广播接收器？

发布于 2024-12-05 09:26:52 字数 622 浏览 3 评论 0原文

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

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

    case AudioManager.RINGER_MODE_VIBRATE:
        Log.i("MyApp","Vibrate mode");
    break;

    case AudioManager.RINGER_MODE_NORMAL:
        Log.i("MyApp","Normal mode");
    break;
}

从上面的代码我可以得到铃声模式。我想做的是监听铃声模式的变化并调用一个函数。

我被告知我可以注册 AudioManager。 RINGER_MODE_CHANGED_ACTION 并在broadcastreceiver onReceive 方法中监听更改意图。听起来很清楚。但我是android新手，真的不知道怎么写。有没有人可以写一段代码并展示它到底是如何工作的，而不是说使用这个或那个:)谢谢

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

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

    case AudioManager.RINGER_MODE_VIBRATE:
        Log.i("MyApp","Vibrate mode");
    break;

    case AudioManager.RINGER_MODE_NORMAL:
        Log.i("MyApp","Normal mode");
    break;
}

From the code above I can get the ringer mode. What I would liek to do is listen the ringer mode changes and call a function.

What I have been told is that I can register the AudioManager. RINGER_MODE_CHANGED_ACTION and listen the change intent in broadcastreceiver onReceive method. It sounds clear. But I am new to android and really dont know how to write it. Is there any one can just write a piece of code and show how exactly it works instead of saying use this or that :) Thank you

在要处理广播的 Activity 或 Service 的 onCreate() 方法中使用以下代码：

      BroadcastReceiver receiver=new BroadcastReceiver(){
          @Override
          public void onReceive(Context context, Intent intent) {
               //code...
          }
      };
      IntentFilter filter=new IntentFilter(
                      AudioManager.RINGER_MODE_CHANGED_ACTION);
      registerReceiver(receiver,filter);

Use the following code inside the onCreate() method of your Activity or Service that you want to process the broadcast:

      BroadcastReceiver receiver=new BroadcastReceiver(){
          @Override
          public void onReceive(Context context, Intent intent) {
               //code...
          }
      };
      IntentFilter filter=new IntentFilter(
                      AudioManager.RINGER_MODE_CHANGED_ACTION);
      registerReceiver(receiver,filter);

另一个解决方案是在 Manifest 中添加一个带有操作的接收器：

<receiver android:name=".receivers.RingerModeStateChangeReceiver" >
    <intent-filter>
        <action android:name="android.media.RINGER_MODE_CHANGED" />
    </intent-filter>
</receiver>

并且您的类 RingerModeStateChangeReceiver 应该扩展 BroadcastReceiver。

Another solution is to add a receiver with an action in Manifest:

<receiver android:name=".receivers.RingerModeStateChangeReceiver" >
    <intent-filter>
        <action android:name="android.media.RINGER_MODE_CHANGED" />
    </intent-filter>
</receiver>

and your class RingerModeStateChangeReceiver should extend BroadcastReceiver.

这是 Kotlin 的更新版本。将其放置在您的 onCreate() 生命周期下。

this.activity?.registerReceiver(object : BroadcastReceiver() {
        override fun onReceive(context: Context, intent: Intent) {
            if (intent.action == AudioManager.RINGER_MODE_CHANGED_ACTION) {
                // Set Player Volume
            }
        }
    }, IntentFilter(AudioManager.RINGER_MODE_CHANGED_ACTION))

Here's an update version in Kotlin. Place this under your onCreate() lifecycle.

this.activity?.registerReceiver(object : BroadcastReceiver() {
        override fun onReceive(context: Context, intent: Intent) {
            if (intent.action == AudioManager.RINGER_MODE_CHANGED_ACTION) {
                // Set Player Volume
            }
        }
    }, IntentFilter(AudioManager.RINGER_MODE_CHANGED_ACTION))
