Android RecyclerView Adaper没有膨胀我的布局？
我正在使用Android RecyclerView Adaper没有膨胀我的布局？,android,android-recyclerview,Android,Android Recyclerview,我正在使用RecyclerviewAdapter显示一些数据。这是我的第一次，我真的遇到了麻烦。在我的移动设备上，RecyclerView变为空 能否RecyclerView.Adapter使用图像膨胀视图 这是sensor_data_listitem.xml <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="ht
