android - 在 FrameLayout 中添加 Google Maps Android API v2 MapFragment 和 View

Question

好的伙计们，我有一个问题。我试图在 FrameLayout 中放置一个 MapFragment 和一个 View 。听起来像是很基本的东西，但我做不到。我不断得到这个:

这是布局:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <FrameLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent" >

        <fragment
            android:id="@+id/map"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            class="com.google.android.gms.maps.MapFragment" />

        <view
            android:id="@+id/myview"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent" 
            class="com.google.android.view.View" />
    </FrameLayout>

</LinearLayout>

代码如下:

package com.example.testarc;

import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

public static MapFragment mapFragment;
public static View myView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    mapFragment = (MapFragment) getFragmentManager().findFragmentById(R.id.map);
    GoogleMap map = mapFragment.getMap();

    myView = (MyView)findViewById(R.id.myview);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

}

提前致谢。

好的，我明白了，它真的很愚蠢:它是 android.view.View，而不是 com.google.android.view.View……显然。 (今天不是我的日子)
