标签： android android-fragments android-recyclerview

我正在做一个培训计划，其中有一个可以回答是或否的问题列表。根据答案文本，问题会改变颜色。结果应显示在单独的活动中。我建议使用片段来保存文本问题的颜色但我有一个错误二进制XML文件行＃22：错误膨胀类片段

以下是代码：

MainActivity：

 openconnection()
    cmd = New SqlCommand("UPDATE products SET quantity = '" + TextBox3.Text + "' WHERE bar_code = '" & ComboBox1.Text & "'", conn)

    For Each i As ListViewItem In
        ListView1.SelectedItems

        cmd.Parameters.AddWithValue("@quantity", Val(TextBox5.Text) + Val(TextBox3.Text))

        cmd.Parameters.AddWithValue("@barcode", TextBox3.Text)

        ListView1.Items.Remove(i)
        ListView1.Items.Remove(i)
        dr = cmd.ExecuteReader()
    Next


End Sub

2 个答案:

答案 0 :(得分：1)

无法使用xml添加片段。
您需要使用片段管理器通过在活动或其他片段中执行片段事务来添加它。

在您的示例中，不必使用片段，因为它只包含单个TextView。

您可以直接使用TextView替换项目xml中的片段标记。

答案 1 :(得分：0)

所以几周后我发现了问题。在更新到Sceneform SDK 1.16时，你们发生了重大变化。较小版本的碰撞，但是会导致我在问题中提及的那些崩溃。解决方案是：

  1. 按照Sceneform SDK存储库的自述文件中的步骤进行操作（将两个src目录复制到您的源代码中，修改两个构建文件）。
  2. 从build.gradle文件中删除现有的com.google.ar.sceneform.ux：sceneform-ux：1.x参考
  3. 在您的项目不依赖旧的AppCompat目录的情况下，重构SDK中的这两个目录以使用androidx导入。
