这是列表项xml

<?xml version="1.0" enCoding="utf-8"?><androID.support.percent.PercentrelativeLayout xmlns:androID="http://schemas.androID.com/apk/res/androID"    xmlns:app="http://schemas.androID.com/apk/res-auto"    androID:orIEntation="vertical"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"><ImageVIEw    androID:background="#d20404"    androID:ID="@+ID/test_image_ID"    androID:layout_wIDth="match_parent"    androID:layout_height="300dp" /><TextVIEw    androID:background="#000"    androID:text="sfgfashdsfg"    androID:layout_below="@+ID/test_image_ID"    app:layout_heightPercent="50%"    androID:layout_wIDth="match_parent"    androID:layout_height="wrap_content" /></androID.support.percent.PercentrelativeLayout>

我有一个github的示例项目

解决方法 我已将此问题打开谷歌.答案是

The height of your ListVIEw row item is insufficIEntly specifIEd.

The first child says it wants to take 60% of the row height (note that
this is heightPercent and not aspectRatio),and the second child says
it wants to take 10% of the row height. But nothing tells ListVIEw how
tall the entire row wants to be. So it ends up being with height 0.

Note that the semantics of height=match_parent do not work in ListVIEw
rows,and if this works in any one particular AndroID platform version
(for however much you can say it works),it is purely incIDental.
