在Android导航抽屉中的MapFragment导致android.view.InflateException

2016-03-06 58 views

我想用一个抽屉与地图片段一起。以下代码适用于API 19，但在模拟器中的API 22和23上引发android.view.InflateException: Binary XML file line #25: Error inflating class fragment。该代码适用于物理设备（在API 19和API 23上测试）。错误指向onCreate中的setContentView(R.layout.activity_map);。在Android导航抽屉中的MapFragment导致android.view.InflateException

我已经看到有关当前错误的类似问题（post），但我不相信这是我的问题，因为这只会影响模拟器设备。

我刚刚测试了一个真正的谷歌Nexus这段代码运行的棉花糖，也没有崩溃。这个问题似乎只能在模拟器中观察到。 – upperlacon

首先，查身份证使用进口android.app.Fragment;而不是import android.support.v4.app.Fragment;。其次，我认为你的问题可能是你需要扩展Fragment而不是直接使用它。我可以提供一个参考。
