BroadcastReceiver广播接收者(二)——利用AndroidManifest.xml注册广播接收者

MainActivity如下:

package cc.testbroadcasta;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
/**
 * Demo描述:
 * 利用AndroidManifest.xml注册广播接收者
 */
public class MainActivity extends Activity {

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		Intent intent = new Intent();
		// 设置Action
		intent.setAction("cc.test");
		// 携带数据
		intent.putExtra("name", "周星驰");
		intent.putExtra("number", 9527);
		// 发送广播
		sendBroadcast(intent);
	}

}

BroadcastReceiverTest如下:

package cc.testbroadcasta;

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

public class BroadcastReceiverTest extends BroadcastReceiver {

	@Override
	public void onReceive(Context context, Intent intent) {
          String name=intent.getStringExtra("name");
          int number=intent.getIntExtra("number", 0);
          System.out.println("接收到广播 name="+name+",number="+number);
	}

	public static void main(String[] args) {

	}

}

main.xml如下:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
   >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="利用AndroidManifest.xml注册广播接收者"
        android:layout_centerInParent="true"/>

</RelativeLayout>

AndroidManifest.xml如下:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="cc.testbroadcasta"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="10"
        android:targetSdkVersion="10" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="cc.testbroadcasta.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <!-- 注册一个广播接收者 -->
        <receiver android:name="cc.testbroadcasta.BroadcastReceiverTest">
            <intent-filter >
                <action android:name="cc.test"/>
            </intent-filter>
        </receiver>
    </application>

</manifest>
