Question

我有一个DrawerLayout，我的DrawerLayout当前显示的是一个包含图像和文本的列表视图，一切都运行良好

现在，我决定在我的DrawerLayout中添加一个标题，并在listview中为几行添加一个特殊字段

谢谢

这张图片说明了我想做的事情：

当用户滚动列表视图时，您是否希望标题滚动到屏幕顶部？如果是这样，只需使用addHeaderView API将标题添加到列表视图中。

如果您希望标题保留在原位，请将其添加到XML

中

Sub ParseJson()

    Dim j As String, sc As Object, num As Long, i

    j = Range("A1").Value 'I'm testing in excel...

    Set sc = CreateObject("ScriptControl")
    sc.Language = "JScript"

    'evaluate the json to create a "response" object
    sc.ExecuteStatement "var response = eval((" & j & "));"

    'create a function to return us a piece of data
    '   based on the passed-in js fragment
    sc.ExecuteStatement "var f = function(s){return eval(s);};"

    'how many reviews ?
    num = sc.Eval("f('response.reviews.length')") '>> 4

    For i = 0 To num - 1
        Debug.Print "------- Review " & i & "---------------"
        Debug.Print sc.Eval("f('response.reviews[" & i & "].author')")
        Debug.Print sc.Eval("f('response.reviews[" & i & "].title')")
        'etc etc
    Next i

End Sub
