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;@Overridepublic 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() {@Overridepublic 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;

}   }  } }; @Overridepublic void onClick(View v) {// TODOswitch (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
