Android两种BroadcastReceiver

Android两种BroadcastReceiver：静态和动态。

第一：静态广播的建立。

（1）在AndroidManifest.xml中声明广播

（2）继承广播接收，对接收到的广播进行处理。

第二：动态广播。

（1）进入Activity时注册动态广播

（2）离开窗口时注销动态广播

实例：

第一：静态广播；

（1）在AndroidManifest.xml中声明静态广播；设置广播接收的动作名

<receiver android:name="广播所在的包名.TestBroadcastReceiver">            <intent-filter>                <action android:name="broadcast_static_action"/>            </intent-filter>    </receiver>

     （2）继承广播接收，对接收到的广播进行处理

public class TestBroadcastReceiver extends BroadcastReceiver{private final static String TAG = TestBroadcastReceiver.class.getSimpleName();@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubString staticAction = intent.getAction();if(staticAction.equals("broadcast_static_action")){Log.i(TAG,"staticAction");}}}

第二：动态广播

（1）建立动态广播类：

class TestDynamicBroadcastReceiver extends BroadcastReceiver{@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubif("broadcast_dynamic_action".equals(intent.getAction())){Log.i(TAG,"intent.getAction()="+intent.getAction());}Log.i(TAG,"dynamic broadcastreceiver");}}

（2）建立动态广播对象

BroadcastReceiver receiver = new TestDynamicBroadcastReceiver();

（3）注册动态广播

public void registerBroadcast(){IntentFilter  intentFilter = new IntentFilter();intentFilter.addAction("broadcast_dynamic_action");registerReceiver(receiver, intentFilter);}

（4）注销动态广播类

public void unRegisterBroadcast(){unregisterReceiver(receiver);}
