首先：如果单个物品的高度大于窗户高度……它就像一个魅力并且正常工作.(A)
第二：如果单个项目的高度小于窗口高度…有时它显示项目(B),有时则不显示！ (C).
第三：我正在使用SwipeRefreshLayout from支持库,当我尝试刷新ListvIEw时,如果我在ListvIEw中有一个项目…如果它的高度小于窗口高度,它不会显示该项目.(C)
我想不出来!!有谁能够帮我
我知道这个问题与SwipeRefreshLayout或ListvIEw的高度有关,因为当我将margintop设置为此视图(作为屏幕高度的一半)时,ListvIEw的工作原理是perefctly.
我的xml文件是：
<androID.support.v4.Widget.SwipeRefreshLayoutandroID:ID="@+ID/swipe_Container"androID:layout_wIDth="match_parent"androID:layout_height="match_parent"androID:layout_margintop="0dp"androID:background="#FFedf1f2"androID:paddingleft="8.5dp"androID:paddingRight="8.5dp"androID:paddingtop="0dp" ><ListVIEw androID:ID="@+ID/List" androID:layout_wIDth="match_parent" androID:layout_height="0dp" androID:layout_weight="1" androID:divIDer="@androID:color/transparent" androID:divIDerHeight="8.5dp" androID:scrollbars="none" ></ListVIEw>@H_404_26@
一切都像魅力一样,直到我在ListvIEw中显示至少多一个项目.但是当我在列表视图中显示一个项目时,我的列表视图没有显示任何内容:(
为什么？我的错在哪里？我哪里错了？
这是我的适配器的getVIEw()(扩展BaseAdapter – 我已经削减了一些代码行)：

我在你的代码中发现了这个问题.
