Android ListView divider strange problem

Question

I have a ListView with a divider of 1pd thickness. But somehow every second divider in the ListView is thicker then the others ...as you can see on the picture

the code of the ListView is real simple :

 <ListView 
         android:id="@+id/directoriesListView"
         android:choiceMode="singleChoice"
         android:clickable="true"
         android:layout_weight="2.5"
         android:cacheColorHint="@null"
         android:footerDividersEnabled="false"
         android:fadingEdge="none"
         style="@style/ListView_NarrowItems"
         />

and the style :

<style
    name="ListView_NarrowItems"
    >
    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_height">fill_parent</item>
    <item name="android:textColor">#FFFFFF</item>
    <item name="android:background">#000000</item>
    <item name="android:divider">#FFFFFF</item>
    <item name="android:dividerHeight">1px</item>
</style>

any idea what is wrong ?

Answer 1

Android is scaling your activity. Add the appropriate <supports-screens> element to your manifest, set to indicate what screen sizes you are handling, and this effect should disappear.

Answer 2

根据此博客文章，这是由于您的应用程序以兼容模式运行，而解决方案是将minSdk和targetSdk放入您的应用程序清单中，如下所示：

<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="8"/>
