二进制 XML 文件第 1 行：膨胀 class 片段 MapFragment 时出错
Binary XML file line #1: Error inflating class fragment MapFragment
我有一个带有一些片段的导航抽屉。每个 Fragment 在布局中都有一个 MapFragment。最初，当应用程序运行导航抽屉时，点击一次打开片段，但是当我第二次点击同一个导航项打开同一个片段时（在访问其他片段之后）我在 onCreateView() 中得到以下错误
Binary XML file line #1: Error inflating class fragment
下面是我的片段代码：

试试这个
