Question

我正在尝试将Google地图添加到我的Android应用中的片段中，并且我收到了android.view.InflateException

我的应用有问题的部分的背景：

我已经使用ViewPager实现了一个TabLayout，其中每个标签都会在ViewPager中显示一个片段
这使用FragmentPagerAdapter
我已经单独测试了API密钥等，可以在我的Android设备上显示基本地图
我尝试在我的XML布局中使用android:name="com.google.android.gms.maps.SupportMapFragment"和class="com.google.android.gms.maps.SupportMapFragment"作为地图片段

以下是一些可能相关文件的要点：

https://gist.github.com/ThrowingSpoon/dbd982c5720e4c27ed47

这两个位置的错误跟踪看起来很有希望：

Caused by: android.view.InflateException: Binary XML file line #7: 
Error inflating class fragment at
android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:782)

android.view.InflateException: Binary XML file line #7:

在此处添加代码：

但不知道我哪里出错了。请帮忙！

Answer 1

在onCreateView方法中。

map = ((SupportMapFragment)getFragmentManager().findFragmentById(R.id.map)).getMap();

尝试更改：

getFragmentManager()

到

getChildFragmentManager() or getSupportFragmentManager()

由于您有嵌套片段，您可能需要传入子片段管理器。此外，如果您正在使用支持v4片段，则应始终使用getSupportFragmentManager（）而不是getFragmentManager（）

Android无法将地图添加到片段。 android.view.InflateException：在android.view.LayoutInflater.createViewFromTag中输出类片段时出错
