Top and bottom dividers not showing in Android listview
提问by InterRaptor
The way I understand it, the divider defined for a listview should appear at the top and bottom of the list too, i.e. above the first item and under the last item.
按照我的理解，为列表视图定义的分隔符也应该出现在列表的顶部和底部，即第一项上方和最后一项下方。
For some reason they don't appear in my listview:
出于某种原因，它们没有出现在我的列表视图中：
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/mainLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background">
<ImageView
android:id="@+id/home"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:paddingTop="3dp"
android:paddingBottom="3dp"

android:divider="@drawable/separatorimg">
</ListView>
</RelativeLayout>
Setting android:footerDividersEnabled to true (which is the answer given in other questions around that matter) doesn't change anything. Also I have no disabled items, unless there is somehow a default footer that would be disabled.
将 android:footerDividersEnabled 设置为 true （这是围绕该问题的其他问题中给出的答案）不会改变任何东西。我也没有禁用的项目，除非有某种默认页脚会被禁用。
Any ideas?
有任何想法吗？
Edit: It seems the divider at the top and bottom dividers appear for a split second when I scroll past the first/last item, and then disappears. It looks as if interface was going to continue, only later to realize that was the last item and then disable the divider.
编辑：当我滚动经过第一个/最后一个项目时，顶部和底部分隔线的分隔线似乎会出现一瞬间，然后消失。看起来好像界面要继续，后来才意识到这是最后一项，然后禁用分隔符。

I solved this problem using help from the following link: Divider disappears from last item in listview if footerview added
我使用以下链接的帮助解决了这个问题：如果添加了footerview，分隔线将从列表视图中的最后一项消失
What I did was add the
我所做的是添加
android:footerDividersEnabled="true"
attribute to the ListView in XML. Then programatically, I added an empty footer view that was selectable using
属性到 XML 中的 ListView。然后以编程方式，我添加了一个空的页脚视图，可以使用
listView.addFooterView(new View(context), null, true);
I didn't try the header, but I expect it to work the same way.
我没有尝试标题，但我希望它以相同的方式工作。

I had the same problem. Here's how I solved it:
我有同样的问题。这是我解决它的方法：
<ListView
android:id="@+id/my_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:divider="@color/transparent"
android:dividerHeight="@dimen/padding_default"
android:footerDividersEnabled="false"
android:headerDividersEnabled="false" >
</ListView>
Then, in the onCreate() method, I have:
然后，在 onCreate() 方法中，我有：
View v = new View(this);
v.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT, 1));
mList.addFooterView(v);

I think you have to set footer using a view below the listview. i had the same problem and this is what i could get as a solution:
我认为您必须使用列表视图下方的视图设置页脚。我有同样的问题，这是我可以得到的解决方案：

I had the same problem, and setting padding and background color solved it.
我遇到了同样的问题，设置填充和背景颜色解决了它。
<ListView
android:id="@+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@color/gray_background"
android:paddingTop="1dp"
android:paddingBottom="1dp"
/>
Here, background color should be same with that of divider with the listview.
在这里，背景颜色应该与列表视图中的分隔线的背景颜色相同。
