嗨，我对 Android 有点陌生，我正在开发一个代码来显示和映射一些标记。我使用了 2 个按钮，一个用于查看地图，另一个用于添加信息。问题是我第一次点击显示地图时，它会显示，但是当我回到“主菜单”并再次点击显示地图时，只是出现黑屏并显示此错误： 

android.view.inflateException: Binary XML file line #11: Error inflating class fragment

我正在使用 API 16，如果我没记错的话，我应该像现在一样使用 MapFragmet，而不是扩展 Fragment，因为它在旧版本中使用，不是吗？

我的 XML：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

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

    <ImageView
        android:id="@+id/logo"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_alignRight="@+id/map"
        android:layout_alignTop="@+id/map"
        android:contentDescription="@string/hintlogo"
        android:src="@drawable/logo" />

</RelativeLayout>
