android.view.InflateException报错

调试项目时候 报错：

 android.view.InflateException: Binary XML file line #49: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference
    Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference
        at android.view.LayoutInflater.createViewFromTag(LayoutInflater.java:786)

仔细检查后 发现：

报错布局

修改后不报错:

真是粗心 竟然犯这低级错误，还调试了半天
