android 飞行模式 注册广播后 三种状态监听

Android4.2以后 飞行模式变更为系统级别，不能再被开发者调用。下面的功能只适应android4.2以前的api。

public class MainActivity extends Activity implements OnClickListener {
	private static final String TAG = "MainActivity";
	private int airState;
	private Button startButton;
	private Button closeButton;
	private Button rButton;
	boolean state = false;
	IntentFilter airIntentFilter;

	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		airIntentFilter = new IntentFilter("android.intent.action.SERVICE_STATE");
		registerReceiver(airReceiver, airIntentFilter);
		state = true;

		startButton = (Button) findViewById(R.id.main_send_start);
		closeButton = (Button) findViewById(R.id.main_send_close);
		rButton = (Button) findViewById(R.id.main_receiver);
		startButton.setOnClickListener(this);
		closeButton.setOnClickListener(this);
		rButton.setOnClickListener(this);
	}

	/**
	 * 打开飞行模式
	 * 
	 * @throws InterruptedException
	 */
	private void satrtAirplane() {
		/*
		 * ContentResolver cr = getContentResolver(); if
		 * (android.provider.Settings.System.getString(cr,
		 * Settings.System.AIRPLANE_MODE_ON).equals("0")) {
		 * 获取当前飞行模式状态,返回的是String值0,或1. 0为关闭飞行, 1为开启飞行
		 */
		Log.i(TAG, "开启飞行");
		Settings.System.putString(getContentResolver(), Settings.System.AIRPLANE_MODE_ON, "1");
		Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
		sendBroadcast(intent);
		Log.i(TAG, "开启飞行执行完毕");
	}

	/**
	 * 关闭飞行模式
	 */
	public void closeAirplane() {
		Log.i(TAG, "关闭飞行模式方法 ");
		Settings.System.putString(getContentResolver(), Settings.System.AIRPLANE_MODE_ON, "0");
		Intent intent = new Intent(Intent.ACTION_AIRPLANE_MODE_CHANGED);
		sendBroadcast(intent);
		Log.i(TAG, "关闭飞行模式方法 执行完毕");
	}

	BroadcastReceiver airReceiver = new BroadcastReceiver() {
		@Override
		public void onReceive(Context context, Intent intent) {
			Bundle bundle = intent.getExtras();
			if (bundle != null) {
				airState = bundle.getInt("state");

				Log.e(TAG, "飞行模式状态 1为开启状态，0为关闭状态 airState==" + airState);
				switch (airState) {
				case 0: // 飞行模式关闭成功状态
					Toast.makeText(getApplicationContext(), "关闭状态airState=" + airState, 0).show();
					Log.i(TAG, "关闭状态  airState=" + airState);
					break;
				case 1: // 飞行模式 关闭过程
					Toast.makeText(getApplicationContext(), "开启状态airState=" + airState, 0).show();
					Log.i(TAG, "开启状态 airState=" + airState);
					break;
				case 3: // 飞行模式开启成功
					Toast.makeText(getApplicationContext(), "开启成功状态airState=" + airState, 0).show();
					Log.i(TAG, "飞行模式状态开启成功  airState=" + airState);
					break;

		}
  	 }
  }
 };					 
	@Override
	public void onClick(View v) {
		// TODO
		switch (v.getId()) {
		case R.id.main_send_start:
			satrtAirplane();
			break;
		case R.id.main_send_close:
			closeAirplane();
			break;
		case R.id.main_receiver:
			if (state) {
				unregisterReceiver(airReceiver);
				state = false;
			} else {
				registerReceiver(airReceiver, airIntentFilter);
				state = true;
			}
			break;
		default:
			break;
		}

	}
}

个人飞行模式小记：

 每次注册飞行模式广播，系统会自动返回当前的 飞行模式状态

当飞行模式未开启： 
       1点击开启后，会接收到广播 airState=3飞行开启成功
       2 点击关闭后,系统无反应
       3 点击取消注册广播，广播关闭 
当飞行模式开启过程中： 
      1点击开启，系统无反应，直至开启成功 ，接收到 3 
      2点击关闭后,系统 关闭飞行模式
 
当飞行模式开启： 
     1 点击开启,系统无反应 
     2 点击关闭后,系统 关闭飞行模式依次 返回 1 0 0 0 

当飞行模式关闭过程中：
    1点击开启后，会接收到广播 airState=3飞行开启成功 
    2 点击关闭后,系统 继续关闭过程
