android 判斷當前是否是飛行模式和偵聽airplane mode change

 在AirplaneModeEnabler中 提供了isAirplaneModeOn方法來判斷當前是否是Airplane mode：
public static boolean isAirplaneModeOn(Context context) {
        return Settings.System.getInt(context.getContentResolver(),
                Settings.System.AIRPLANE_MODE_ON, 0) != 0;
    } www.2cto.com
 
偵聽是否airplane mode 發生改變，可以用注冊intentFilter 來偵聽。
BroadcastReceiver  mReceiver = new AirplaneModeBroadcastReceiver();
IntentFilter intentFilter = new IntentFilter(Intent.ACTION_AIRPLANE_MODE_CHANGED);
registerReceiver(mReceiver, intentFilter);
 
private class AirplaneModeBroadcastReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (action.equals(Intent.ACTION_AIRPLANE_MODE_CHANGED)) {
               // add your code here ………
            }
        }
    }
