[原]android 中如何飞行模式的几个操作

• Android中如何判断系统当前是否处于飞行模式中：

 

public static boolean IsAirModeOn(Context context) {
		return (Settings.System.getInt(context.getContentResolver(),
				Settings.System.AIRPLANE_MODE_ON, 0) == 1 ? true : false);
	}

• 如何切换飞行模式

 

public static void setAirplaneMode(Context context, boolean enabling) {
		Settings.System.putInt(context.getContentResolver(),
				Settings.System.AIRPLANE_MODE_ON, enabling ? 1 : 0);
		Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
		intent.putExtra("state", enabling);
		context.sendBroadcast(intent);
	}

 

• 如何注册和取消自动飞行时间

 

注册

 

AlarmManager am = (AlarmManager) context
			.getSystemService(Context.ALARM_SERVICE);
Intent intent = new Intent(AIR_ALERT_ACTION);
	Parcel out = Parcel.obtain();
	air.writeToParcel(out, 0);
	out.setDataPosition(0);
	intent.putExtra(AIR_RAW_DATA, out.marshall());
	PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent,
			PendingIntent.FLAG_CANCEL_CURRENT);
am.set(AlarmManager.RTC_WAKEUP, atTimeInMillis, sender);

取消

 

AlarmManager am = (AlarmManager) context
				.getSystemService(Context.ALARM_SERVICE);
	endingIntent sender = PendingIntent.getBroadcast(context, 0,
				new Intent(action), PendingIntent.FLAG_CANCEL_CURRENT);
am.cancel(sender);

•  如何控制切换飞行模式的硬件（cell,Bluetooth,wifi）

   

  Settings.System.putString(context.getContentResolver(),
  				Settings.System.AIRPLANE_MODE_RADIOS, air_mode_radios);

  air_mode_radios为一个这样的字符串，看android源码中android/provider/Settings.java

  	
  /***
           * Whether Airplane Mode is on.
           */
          public static final String AIRPLANE_MODE_ON = "airplane_mode_on";
          /***
           * Constant for use in AIRPLANE_MODE_RADIOS to specify Bluetooth radio.
           */
          public static final String RADIO_BLUETOOTH = "bluetooth";
          /***
           * Constant for use in AIRPLANE_MODE_RADIOS to specify Wi-Fi radio.
           */
          public static final String RADIO_WIFI = "wifi";
          /***
           * Constant for use in AIRPLANE_MODE_RADIOS to specify Cellular radio.
           */
          public static final String RADIO_CELL = "cell";
          /***
           * A comma separated list of radios that need to be disabled when airplane mode
           * is on. This overrides WIFI_ON and BLUETOOTH_ON, if Wi-Fi and bluetooth are
           * included in the comma separated list.
           */
          public static final String AIRPLANE_MODE_RADIOS = "airplane_mode_radios";
          /***
           * A comma separated list of radios that should to be disabled when airplane mode
           * is on, but can be manually reenabled by the user.  For example, if RADIO_WIFI is
           * added to both AIRPLANE_MODE_RADIOS and AIRPLANE_MODE_TOGGLEABLE_RADIOS, then Wifi
           * will be turned off when entering airplane mode, but the user will be able to reenable
           * Wifi in the Settings app.
           *
           * {@hide}
           */
          public static final String AIRPLANE_MODE_TOGGLEABLE_RADIOS = "airplane_mode_toggleable_radios";

  如果air_mode_radios=“cell,bluetooth,wifi”,这就便是切换飞行模式是切换字符串中的这cell,bluetooth,wifi硬件，我们可以通过设置该字符串的值，来控制这三个硬件是否在切换飞行模式是进行切换状态。
