顶部和底部的分隔没有显示在Android的列表视图 [英] Top and bottom dividers not showing in Android listview

问题描述

我的理解是，对于一个列表视图定义的分应该出现在列表的顶部和底部也一样，即上述第一项和最后一项下。

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.

有关某种原因，他们不会出现在我的列表视图：

For some reason they don't appear in my listview:

<?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:paddingLeft="3dp"
    android:paddingTop="3dp"
    android:paddingBottom="3dp"
    android:src="@drawable/homeicon"/>

<TextView
    android:id="@+id/titleBar"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="Page Title" 
    android:layout_marginLeft="10dp" 
    android:paddingTop="3dp"
    android:textSize="18sp" 
    android:textStyle="bold" 
    android:typeface="serif" 
    android:textColor="#FFFFFF"
    android:layout_centerHorizontal="true"/>

<ImageView
    android:id="@+id/back"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingRight="8dp"
    android:paddingTop="8dp"
    android:src="@drawable/backicon" 
    android:layout_alignParentRight="true"/>


<ImageView
    android:id="@+id/separator1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/home"
    android:scaleType="fitXY"
    android:src="@drawable/separatorimg" />


<ListView
    android:id="@android:id/android:list" 
    android:layout_below="@+id/separator1"
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:cacheColorHint="#00000000"
    android:divider="@drawable/separatorimg">
</ListView>

</RelativeLayout>

设置的android：footerDividersEnabled为true（这是在其他周围的物质的问题给出的答案）不会改变任何东西。另外我有没有禁用的项目，除非有某种方式，将被禁用默认页脚。

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.

任何想法？

编辑：看来分频器在顶部和底部的分隔第二出现的一瞬间，当我滚动过去的第一个/最后一个项目，然后消失。它看起来好像界面会继续，只是后来意识到那是最后一个项目，然后禁用分频器。

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.

推荐答案

我解决了从下面的链接使用帮助，这个问题：<一href="http://stackoverflow.com/questions/5661668/divider-disappears-from-last-item-in-listview-if-footerview-added">Divider从最后一项消失在列表视图，如果footerview添加

I solved this problem using help from the following link: Divider disappears from last item in listview if footerview added

我所做的是添加

  android:footerDividersEnabled="true" 

属性在XML中的ListView。然后编程，我添加了一个空的页脚视图使用是可选的。

attribute to the ListView in XML. Then programatically, I added an empty footer view that was selectable using

 listView.addFooterView(new View(context), null, true);

我没有尝试的头，但我希望它的工作方式相同。

I didn't try the header, but I expect it to work the same way.
