Android出现错误：InflateException:Binary XML file

 

错误显示：在XML文件的第一行

<sunny.example.ahthreeview.TopBar xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:custom="http://schemas.android.com/apk/res-auto"
    android:id="@+id/topBar"
    android:layout_width="match_parent"
    android:layout_height="40dp"
    custom:leftBackground="@drawable/ic_launcher"
    custom:leftText="Back"
    custom:leftTextColor="#FFFFFF"
    custom:rightBackground="@drawable/ic_launcher"
    custom:rightText="More"
    custom:rightTextColor="#FFFFFF"
    custom:title="自定义标题"
    custom:titleTextColor="#123412"
    custom:titleTextSize="15sp">
</sunny.example.ahthreeview.TopBar>

包名应该是上面所示，写成了Topbar
