注册在AndroidManifest.xml本地广播接收器？ [英] Register a Local BroadcastReceiver in AndroidManifest.xml?

问题描述

反正在AndroidManifest.xml中注册一个BroadcastReceiver并接收由LocalBroadcastManager？

发送广播

目前我必须调用

  registerReceiver（广播接收器接收器，过滤器的IntentFilter）
 

要注册一个接收器，声明在AndroidManifest.xml将无法工作。但是，这意味着我必须确切地知道接收的包名和类名，而不仅仅是意图过滤器。是否有可能宣布接收清单文件？

以下是我目前的code。

AndroidManifest.xml中：

  ...
＆lt;接收
    机器人：名字=com.example.test.MessageReceiver
    机器人：启用=真正的＆GT;
    ＆所述;意图滤光器＆gt;
        ＆lt;作用机器人：名字=com.m2x.test.intent.MESSAGE_RECEIVED/＆GT;
    ＆所述; /意图滤光器＆gt;
＆LT; /接收器＆GT;
...
 

MainActivity.java：

 意向意图=新的Intent（）;
intent.setAction（com.m2x.test.intent.MESSAGE_RECEIVED）;LocalBroadcastManager经理= LocalBroadcastManager.getInstance（mContext.get（））;
manager.sendBroadcast（意向）;
 

MessageReceiver.java

 公共类的messageReceiver扩展广播接收器{    @覆盖
    公共无效的onReceive（上下文的背景下，意图意图）{        如果（intent.getAction（）。等于（com.m2x.test.intent.MESSAGE_RECEIVED））{
            Toast.makeText（背景下，用户接收到消息，Toast.LENGTH_SHORT）.show（）;
        }    }
}
 

解决方案

没有，你不能。

本地广播接收器不是一个真正的广播接收器，实际上它是一个列表回调功能。结果

Is there anyway to register a BroadcastReceiver in AndroidManifest.xml and receives broadcast that is send by a LocalBroadcastManager?

Currently I must call

registerReceiver(BroadcastReceiver receiver, IntentFilter filter) 

to register a Receiver, declare in AndroidManifest.xml won't work. But this means I must know exactly the receiver's package name and class name, not just the intent filter. Is it possible to declare the receiver in the manifest file?

following is my current code.

AndroidManifest.xml:

...
<receiver 
    android:name="com.example.test.MessageReceiver"
    android:enabled="true" >
    <intent-filter>
        <action android:name="com.m2x.test.intent.MESSAGE_RECEIVED" />
    </intent-filter>
</receiver>
...

MainActivity.java:

Intent intent = new Intent();
intent.setAction("com.m2x.test.intent.MESSAGE_RECEIVED");

LocalBroadcastManager manager = LocalBroadcastManager.getInstance(mContext.get());
manager.sendBroadcast(intent);

MessageReceiver.java

public class MessageReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {

        if (intent.getAction().equals("com.m2x.test.intent.MESSAGE_RECEIVED")) {
            Toast.makeText(context, "user message received", Toast.LENGTH_SHORT).show();
        }

    }
}

解决方案

No, you can't.

A local BroadcastReceiver isn't a real BroadcastReceiver, actually its a list of callbacks functions.
You can check the source code of LocalBroadcastManager.java.
