我正在创建一个 Google Map API v2 应用程序，但我在 LogCat 中发现了一个问题，并且 O 不知道如何解决它，谁能帮助我？

我正在使用 API Google 16。我已导入 Google Play 服务并添加到项目中，但我在 LogCat 中遇到了这个问题。

我将不胜感激。

主要的.xml

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

    <fragment
        android:name="com.google.android.gms.maps.SupportMapFragment"
        class="android.support.v4.app.DialogFragment"
        android:id="@+id/map"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
</LinearLayout>

你的问题是这个错误行：

Caused by: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

基本上，如果您收到，那么您的问题可能是因为/是该库的一部分，因此fragment/class not found error缺乏对该库的良好参考：google-play-servicesMapFragmentSupportMapFragment

检查你的Android Dependencies文件夹是否(blue)在google-play-services (orange)里面，你会发现有这个类的com.google.android.gms.maps包：(green)MapFragment(red)

在此处输入图像描述

如果不是这种情况，您可以查看我写的这篇博文的前 3 个步骤，以了解如何正确引用这个包：
