BroadcastReceiver register 广播的动态注册方式

1.动态注册方式特点：在代码中进行注册后，当应用程序关闭后，就不再进行监听。

下面是具体的例子：

BroadcastTest.java

package com.czz.test;import android.app.Activity;import android.content.BroadcastReceiver;import android.content.Context;import android.content.Intent;import android.content.IntentFilter;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.Toast;public class BroadcastTest extends Activity {private static final String ACTION = "com.czz.test.SENDBROADCAST";@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);this.setContentView(R.layout.broadcast_test);Button btnSendBroadcast = (Button) this.findViewById(R.id.send);final Button btnRegisteBroadcast = (Button) this.findViewById(R.id.registe);final Button btnUnregisteBroadcast = (Button) this.findViewById(R.id.unregiste);btnRegisteBroadcast.setEnabled(true);btnUnregisteBroadcast.setEnabled(false);btnSendBroadcast.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stubsendBroadcast(new Intent(ACTION));}});btnRegisteBroadcast.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stubIntentFilter filter = new IntentFilter();filter.addAction(ACTION);registerReceiver(myReceiver, filter);btnRegisteBroadcast.setEnabled(false);btnUnregisteBroadcast.setEnabled(true);}});btnUnregisteBroadcast.setOnClickListener(new OnClickListener(){@Overridepublic void onClick(View v) {// TODO Auto-generated method stubunregisterReceiver(myReceiver);btnRegisteBroadcast.setEnabled(true);btnUnregisteBroadcast.setEnabled(false);}});}private BroadcastReceiver myReceiver = new BroadcastReceiver(){@Overridepublic void onReceive(Context context, Intent intent) {// TODO Auto-generated method stubToast.makeText(context, "myReceiver receive", Toast.LENGTH_SHORT).show();}};}

broadcast_test.xml

<?xml version="1.0" encoding="utf-8"?><FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="fill_parent"android:layout_height="fill_parent"><ImageViewandroid:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_gravity="center_horizontal"        android:layout_marginTop="0px"        android:visibility="gone"        android:src="@drawable/earth"/><LinearLayout    android:orientation="vertical"    android:layout_width="fill_parent"    android:layout_height="wrap_content"    ><TextView      android:layout_width="fill_parent"     android:layout_height="wrap_content"     android:text="Broadcast test"    android:singleLine="true"    android:gravity="center_horizontal"    /><Button  android:id="@+id/send"    android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="send broadcast"    android:layout_marginLeft="20px"    /><Button  android:id="@+id/registe"    android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="registReceiver"    android:layout_marginLeft="20px"    android:layout_marginTop="20px"    /><Button  android:id="@+id/unregiste"    android:layout_width="wrap_content"     android:layout_height="wrap_content"     android:text="unregistReceiver"    android:layout_marginLeft="20px"    android:layout_marginTop="20px"    /></LinearLayout></FrameLayout>

------------------------------------------------------------------------------------

2.静态注册方式是在AndroidManifest.xml的application里面定义receiver并设置要接收的action。静态注册方式的特点：不管改应用程序是否处于活动状态，都会进行监听，比如某个程序时监听内存 的使用情况的，当在手机上安装好后，不管改应用程序是处于什么状态，都会执行改监听方法中的内容。

下面是具体的例子：

MyReceiver.java

public class MyReceiver extends BroadcastReceiver{          //定义日志标签  private static final String TAG = "Test";  @Override public void onReceive(Context context, Intent intent){      //输出日志信息      Log.i(TAG, "MyReceiver onReceive--->");  }  }  

AndroidManifest.xml 

com.android.broadcast.RECEIVER_ACTION

是你activity中的ACTION

<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android"   package="com.android.broadcast"   android:versionCode="1"   android:versionName="1.0"> <uses-sdk android:minSdkVersion="10" /> <application android:icon="@drawable/icon" android:label="@string/app_name">     <activity android:name=".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>     <receiver android:name="MyReceiver"> <intent-filter>     <action android:name="com.android.broadcast.RECEIVER_ACTION"/> </intent-filter>     </receiver> </application> </manifest>
