代码中注册和注销使用BroadcastReceiver

1、定义一个 BroadcastReceiver ：

 

 

private BroadcastReceiver receiver = new BroadcastReceiver() {
		@Override
		public void onReceive(Context context, Intent intent) {
			// TODO Auto-generated method stub
			Log.i(TAG, "will finish...." + intent.getAction());
			finish();
		}
	};

 

 

2、在oncreate 方法中进行注册：

 

     registerReceiver(receiver, new IntentFilter(ACTION));

 

3、使用的时候：

 

    Intent intent = new Intent();

intent.setAction(ACTION);
sendBroadcast(intent);

 

4、在onDestroy 方法中进行注销，反复注销会报错：

 

     unregisterReceiver(receiver);

Log.i(TAG, "has unregist....");
