本文介绍如何在Android应用中使用广播接收器接收并处理广播消息，通过发送Intent实现消息传递。

package com.src.hero.org;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

public class MyReceiver extends BroadcastReceiver{

	@Override
	public void onReceive(Context context, Intent intent) {
		// TODO Auto-generated method stub
		String message=intent.getStringExtra("message");
		Log.v("MyReceiver", "message:"+message);
	}

}
package com.src.hero.org;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

/**
 * Receiver To Study
 * 
 * @author Hero
 * 
 */
public class ReceiverActivity extends Activity implements OnClickListener {
	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		Button btn_Sent = (Button) findViewById(R.id.btn_Sent);
		btn_Sent.setOnClickListener(this);
	}

	public void onClick(View v) {
		// TODO Auto-generated method stub
		switch (v.getId()) {
		case R.id.btn_Sent:
			String start_Receiver="com.src.hero.org.ReceiverActivity";
			Intent sent_intent=new Intent(start_Receiver);
			sent_intent.putExtra("message", "广播测试");
			sendBroadcast(sent_intent);
			break;
		default:
			System.out.println("default");
			break;
		}
	}
}
           manifest中添加注册receiver
           <receiver android:name=".MyReceiver" >
            <intent-filter>
                <action android:name="com.src.hero.org.ReceiverActivity" />
            </intent-filter>
        </receiver>
