Android 如何知道广播接收机中的飞行模式是打开还是关闭？

我在这个解决方案的其他问题中看到了多个答案，以了解飞机模式是否改变：

IntentFilter intentFilter = new      
IntentFilter("android.intent.action.AIRPLANE_MODE_CHANGED");

BroadcastReceiver receiver = new BroadcastReceiver() {
      @Override
      public void onReceive(Context context, Intent intent) {
            Log.d("AirplaneMode", "Service state changed");
      }
};

context.registerReceiver(receiver, intentFilter);

但现在我想知道飞机模式是在onReceive方法上打开还是关闭的

谢谢。

试试这个

IntentFilter intentFilter = new      
IntentFilter("android.intent.action.AIRPLANE_MODE_CHANGED");

BroadcastReceiver receiver = new BroadcastReceiver() {
      @Override
      public void onReceive(Context context, Intent intent) {
            Log.d("AirplaneMode", "Service state changed");
            boolean isAirplaneMode = isAirplaneModeOn(context);
      }
};

context.registerReceiver(receiver, intentFilter);

private static boolean isAirplaneModeOn(Context context) {

   return Settings.System.getInt(context.getContentResolver(),
           Settings.System.AIRPLANE_MODE_ON, 0) != 0;

}

注 在Jelly Bean 4.2中，此设置已移动到

设置。全局
尝试此代码

@Override
public void onReceive(Context context, Intent intent) {

boolean isAirplaneModeOn = intent.getBooleanExtra("state", false);
if(isAirplaneModeOn){

   // AP mode is on
} else {
   // AP mode is off
  }
}

如中所述，您可以通过以下方式检查飞机模式状态：

@SuppressWarnings("deprecation")
@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
public static boolean isAirplaneModeOn(Context context) {        
    if (Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR1) {
        return Settings.System.getInt(context.getContentResolver(), 
                Settings.System.AIRPLANE_MODE_ON, 0) != 0;          
    } else {
        return Settings.Global.getInt(context.getContentResolver(), 
                Settings.Global.AIRPLANE_MODE_ON, 0) != 0;
    }       
}

我试过了，但对我不起作用。无论如何谢谢你！更喜欢在Intent类中使用常量。从安卓10开始，它是
公共静态最终字符串动作\u飞行\u模式\u更改=“安卓.意图.动作.飞行\u模式”
IntentFilter intentFilter = new      
IntentFilter("android.intent.action.AIRPLANE_MODE_CHANGED");

BroadcastReceiver receiver = new BroadcastReceiver() {
      @Override
      public void onReceive(Context context, Intent intent) {
            Log.d("AirplaneMode", "Service state changed");
            boolean airplane_active = isAirplaneModeOn(context);
      }
};

context.registerReceiver(receiver, intentFilter);
