如何创建行数和列数未知的动态表格布局？

Question

我想创建动态表格布局。我有这些节点（因为每个节点都有单独的样式）：

• 标题行
• 标题单元格
• 奇数行
• 奇数行单元格
• 偶数行

• 偶数行单元格 像这样：

  在此处输入代码

  <TableRow
      android:id="@+id/header_row"
      style="@style/HeaderRow"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" >
  
      <TextView
          android:id="@+id/header_tv"
          style="@style/HeaderText"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content" />
  </TableRow>
  
  <TableRow
      android:id="@+id/bodyrow_odd"
      style="@style/BodyRowOdd"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" >
  
      <TextView
          android:id="@+id/body_tv_odd"
          style="@style/BodyTextOdd"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content" />
  </TableRow>
  
  <TableRow
      android:id="@+id/bodyrow_even"
      style="@style/BodyRowEven"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" >
  
      <TextView
          android:id="@+id/body_tv_even"
          style="@style/BodyTextEven"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content" />
  </TableRow>
  

如果我想通过膨胀每个节点来创建动态界面，我必须让每个节点在单独的 xml 中？`在此处输入代码
