一、静态注册广播

//在清单文件配置<receiver><receiver/>
<receiver

android:name=".receiver1.BootComleteReceiver"

android:enabled="true"   

android:exported="true">   

<intent-filter>       

<action  android:name="android.intent.action.BOOT_COMPLETED" />   

</intent-filter>

</receive

---

二、模拟开机网络状态

/**

* 广播接收器：模拟动态监听 ：网络变化（系统广播）

创建一个Receiver对象，继承BroadcastReceiver

*/

public class NetWorkChangeReceiver  extends BroadcastReceiver {

@Override

    public void onReceive(Context context, Intent intent) {

//获取网络管理器类

ConnectivityManager connectivityManager = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);

//网络信息

NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();

if (activeNetworkInfo!=null && activeNetworkInfo.isAvailable()){

Toast.makeText(context,"有网",Toast.LENGTH_SHORT).show();

}else{

Toast.makeText(context,"没网",Toast.LENGTH_SHORT).show();

               }

        }

}

//模拟完毕后要在Activity中注册广播

//注册广播

netWorkChangeReceiver = newNetWorkChangeReceiver();

//广播接收器

IntentFilter intentFilter = newIntentFilter();//意图过滤器intentFilter.addAction("android.net.conn.CONNECTIVITY_CHANGE");//接受网络变化registerReceiver(netWorkChangeReceiver, intentFilter);//注册广播  谁接  谁收

//有注册就有取消注册

protected void onDestroy() {

super.onDestroy();

//注销广播

    unregisterReceiver(netWorkChangeReceiver);

}

---

三、动态注册

//1.首先创建几个receiver对象，在清单文件里会生成对应的<receiver><receiver/>  ，粗体部分则为自定义.name

<receiver

android:name=".receiver2.MyReceiver1"

android:enabled="true"   

android:exported="true">   

<intent-filter android:priority="80">       

<action  android:name="com.jiyun.action.ABC" />   

</intent-filter>

</receiver>

//2.代码实现注册

//<1>标准广播

Intent intent =new Intent("com.jiyun.action.ABC");

intent.putExtra("name" ,"我是广播传过来的值");     //广播同样可以传值

sendBroadcast(intent);

//<2>有序广播——具有拦截广播的功能

Intent intent1 =new Intent("com.jiyun.action.ABC");

sendOrderedBroadcast(intent1 ,null);

//3.有序广播的拦截功能

abortBroadcast();//拦截广播

//4.广播中非页面之间的启动页面

Intent intentMain =new Intent(context, MainActivity.class);

intentMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); //非页面之间启动页面， 需要自带加载任务栈

context.startActivity(intentMain);
