android - 广播接收器未被调用

Question

在我的 fragment 中，我有一个按钮，当按下按钮时，我通过以下方式广播自定义 Intent :

package com.my.store.fragments.shopping;

public class ShoppingFragment extends Fragment{
    ...
    @Override
    public void onStart(){
       super.onStart()

       myButton.setOnClickListener(new OnClickListener(){
             @Override
             public void onClick(View v){
                broadcastMyIntent(v);
             }
       });
    }

    public void broadcastMyIntent(View view){
     Intent intent = new Intent();
     intent.setAction("com.my.store.fragments.shopping.CUSTOM_INTENT");
     getActivity().sendBroadcast(intent);
    }
}

然后，我定义了一个广播接收器:

package com.my.store.utils;

public class MyReceiver extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Receive my intent", Toast.LENGTH_LONG).show();
    }
}

我在 AndroidManifest.xml 中注册接收器:

<application
    ...>
    <activity ...>
       ...
    </activity>

    <!--this is the receiver which doesn't work-->
    <receiver android:name="com.my.store.utils.MyReceiver"> 
          <action android:name="com.my.store.fragments.shopping.CUSTOM_INTENT"/>
    </receiver>

    <!--I have another receiver here, it is working fine-->
   <receiver android:name="com.my.store.utils.AnotherReceiver">
        <intent-filter>
            <action android:name="android.intent.action.BOOT_COMPLETED"/>
        </intent-filter>
    </receiver>
</application>

我运行我的应用程序，当我按下按钮时，我的接收器没有被调用。为什么？

你忘了包围你的 <action>带有 <intent-filter> 的元素容器。
