1. 創建Receiver，兩種方式，動態和靜態：

? （1）靜態注冊：

?首先自定義個Receiver，

public?class?MyReceiver?extends?BroadcastReceiver?{

????@Override
????public?void?onReceive(Context?context,?Intent?intent)?{
????????//?TODO?Auto-generated?method?stub
????????Toast.makeText(context,?"MyReceiver?broadcast",?10000).show();
????}

}

?

然后在AndroidManifest注冊即可：

????????<receiver?android:name=".MyReceiver">
????????????<intent-filter>
????????????????<action?android:name="com.test.broadcasting"?/>
????????????</intent-filter>
????????</receiver>

?

?

? （2）動態注冊：

????private?void?regReceiver()?{
????????IntentFilter?intentFilter?=?new?IntentFilter();
????????intentFilter.addAction("com.test.broadcasting");
????????//?注冊BroadcastReceiver
????????this.registerReceiver(receiver,?intentFilter);

????????//?取消注冊
????????//?this.unregisterReceiver(receiver);
????}

????private?BroadcastReceiver?receiver?=?new?BroadcastReceiver()?{
????????@Override
????????public?void?onReceive(Context?context,?Intent?intent)?{
????????????Toast.makeText(context,?"receive?broadcast",?10000).show();
????????}
????};

?

?

??? 2.發送廣播：

這個非常簡單，只需一行代碼即可：

this.sendBroadcast(new?Intent("com.test.broadcasting"));

?

?

3. 應用場景：

? 最常見的就是SD插拔的廣播注冊(android.content.Intent.ACTION_MEDIA_MOUNTED).
