推荐答案

在LIST_VIEW_ITEM，添加一个虚拟查看您的RelativeLayout后，敷他们都在垂直的LinearLayout这样

In list_view_item, add a dummy View after your RelativeLayout and wrap them all at vertical LinearLayout like this

<LinearLayout
  android:orientation="vertical"

>

<RelativeLayout>
...
...
</RelativeLayout>

<View
        android:id="@+id/shadow"
        android:layout_width="fill_parent"
        android:layout_height="3dip" <!or your needed height value/>
        android:background="@drawable/shadow_drawable"

</View>

</LinearLayout>

在绘制文件夹添加新shadow_drawable.xml，并把这个吧

and at drawable folder add the new shadow_drawable.xml and put this at it

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">    
    <gradient
        android:startColor="@color/#000000" <!black/>
        android:endColor="@color/#FFFFFF" <!white/>
        android:angle="90" <! angle of the gradient>
        >
    </gradient>
</shape>
