Xamarin Android布局问题

Question

我有一个简单的Xamarin布局，无法正确呈现。行（4,5,6）上有多个只包含单个UI元素的列。这是XML。根据其他SO帖子，设置layout_span=2应该可以解决问题。但它似乎并不奏效。

<?xml version="1.0" encoding="utf-8"?> 
 
<TableLayout xmlns:p1="http://schemas.android.com/apk/res/android" 
 
    p1:minWidth="25px" 
 
    p1:minHeight="25px" 
 
    p1:layout_width="match_parent" 
 
    p1:layout_height="match_parent" 
 
    p1:id="@+id/tableLayout1"> 
 
    <TableRow 
 
     p1:id="@+id/tableRow1" 
 
     p1:layout_width="match_parent" 
 
     p1:gravity="center_horizontal" 
 
     p1:layout_weight="1"> 
 
     <TextView 
 
      p1:text="Image Path" 
 
      p1:textAppearance="?android:attr/textAppearanceLarge" 
 
      p1:id="@+id/pathLabel" /> 
 
     <EditText 
 
      p1:inputType="text"

我检查你的代码，它是正确的。

尝试关闭/打开IDE，从设备上删除应用程序并重新构建项目。
