动态注册的广播

记录一下在项目中动态使用广播的方法

private SpeechReceiver receiver;
/**
 * 注册动态广播接收极光推送的信息
 */
public static final String ScanAction = "com.xgs.ui.scan";

public class SpeechReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

     }

}

在当前页面创建的时候注册这个广播

receiver = new SpeechReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(ScanAction);
registerReceiver(receiver, filter);

在发送广播的位置 

Intent intents = new Intent(注册广播的class.ScanAction);
intents.putExtra("ssa", ssa);
context.sendBroadcast(intents);

intent 可传递数据 

在结束页面的时候回收

if (null != receiver) {
    unregisterReceiver(receiver);
}

就可以了
