我创建了一个小部件,点击后必须启动一个Activity,我按照这个问题的答案 [Clickable widgets in android]

但是,点击后我无法得到任何回复,这是我的小部件的java代码:

Widget.java

    public class Widget extends AppWidgetProvider
{
    private static String YOUR_AWESOME_ACTION = "YourAwesomeAction";
    public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds)
    {
        Intent intent = new Intent(context, HomeTeamSelector.class);
        intent.setAction(YOUR_AWESOME_ACTION);
        PendingIntent pendingIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
        RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget);
        views.setOnClickPendingIntent(R.id.widgetLayout, pendingIntent);

    }

    @Override
    public void onReceive(Context context, Intent intent)
    {
        super.onReceive(context, intent);
        if (intent.getAction().equals(YOUR_AWESOME_ACTION))
        {
            Intent x = new Intent(context,HomeTeamSelector.class);
            context.startActivity(x);
        }
    }
}

这是xml文件的代码:

widget.xml

    <?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:id="@+id/widgetLayout"
    android:layout_height="match_parent"
    android:transitionGroup="true">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/app_name_extra"
        android:id="@+id/textView"
        android:layout_centerInParent="true"
        android:textColor="@color/colorPrimary"
        android:textSize="30sp" />


</RelativeLayout>

呈现窗口小部件,但是我无法获得任何关于点击的响应,可能导致此问题的原因以及如何修复?

尝试在AndroidMenifest.xml中添加AppWidgetProvider接收器,如

<receiver
        android:name=".Widget"
        android:label="@string/widget">
        <intent-filter>
            <action android:name="android.appwidget.action.APPWIDGET_UPDATE" />
        </intent-filter>

        <meta-data
            android:name="android.appwidget.provider"
            android:resource="@xml/widget" />
    </receiver>
