Android判斷是否飛行模式已經監聽飛行模式

1.判斷是否飛行模式：

 private boolean isAirPlaneModeOn(){
        int mode = 0;
        try {
            mode = Settings.Global.getInt(getContentResolver(), Settings.Global.AIRPLANE_MODE_ON);
            }catch (SettingNotFoundException e) {
            e.printStackTrace();
            }
            return mode == 1;//爲1的時候是飛行模式
            }

2.廣播監聽飛行模式：

private BroadcastReceiver airplaneModeOn = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
 String action = intent.getAction();
 if(action.equals(Intent.ACTION_AIRPLANE_MODE_CHANGED)){//飛行模式狀態改變
   //To Do
 }
 }
 };
 註冊廣播：
 IntentFilter filter = new IntentFilter(Intent.ACTION_AIRPLANE_MODE_CHANGED);
 registerReceiver(airplaneModeOn, filter);
