Caused by: android.view.InflateException: Binary XML file line #57: Error inflating class null

错误原因是因为我在xml布局文件中讲View写成了view(注意首字母的大小写区分)

错误代码如下

<view android:layout_width="fill_parent"
          android:layout_height="1dp"
          android:background="#000"
          android:layout_below="@+id/set_tag"
          android:layout_marginBottom="20dp"/>

错误日志如下
