如何preVIEW Android的ListView中自定义行头布局 [英] How to preview Android ListView with custom row and header layout

问题描述

我已经创建了一个自定义布局页眉和行项目很多次，但总是什么惹恼我是Android Studio中的UI preVIEW不显示preVIEW列表视图。显然，因为自定义布局由ListView控件或CursorAdapter的，但什么编程方式加载，如果我想一些如何指定XML页眉和页脚的布局，这样我可以看到一个preVIEW。任何一个知道如何做到这一点？

I have created a list view with a custom layout for the header and rows items many times but what always annoys me is the UI preview in Android Studio does not show a preview. Obviously because the custom layouts are loaded programmatically by the ListView or CursorAdapter but what if I wanted to some how specify a header and footer layout in xml so that I could see a preview. Any one know how to do that?

推荐答案

您可以使用 工具：列表项 。只需添加工具命名空间布局的根

You can use tools:listitem. Just add the tools namespace in the root of the layout

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    (...)

，然后在你的ListView设置列表项的布局

and then in your ListView set your list item layout

 <ListView
    android:id="@+id/mylistView"
    tools:listitem="@layout/my_list_item"
    (...)

也可以设置页眉/页脚 listheader / listfooter 。

Is also possible to set header/footer with listheader/listfooter.
