java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.paipaixiu/com.example.paipaixiu.MASetSomeThing}: android.view.InflateException: Binary XML file line #19: Attempt to invo

这个报错是因为Android布局的控件

<view
    android:layout_width="match_parent"
    android:layout_height="1dp"/>

无法识别，要写成 <View ....  />
V要大写，小写编译时不识别
