android: 最容易broadcast sample

android: 最简单broadcast sample

				//某个Activity某个按钮里发出broadcast
				Intent intent = new Intent("test_broadcast");
				sendBroadcast(intent);

		<!-- manifest的application里 -->
		<receiver android:name=".MyBroadcastReceicer">
			<intent-filter>
				<action android:name="test_broadcast"></action>
			</intent-filter>
		</receiver>

 

 

 

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
//写一个 类接收Broadcast
public class MyBroadcastReceicer extends BroadcastReceiver{

	@Override
	public void onReceive(Context arg0, Intent arg1) {
		//接收到broadcast 总要干点什么吧
		Log.d("bbbbbb", "-----------干点什么-------------");
	}
}

 这样一个最简单的broadcast就完成了
