改写ListView样式

<ListView 
		android:id="@id/android:list"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:drawSelectorOnTop="true"
        android:listSelector="@drawable/selector"
        android:divider="@drawable/list_line"/>

 selector:如下

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 

<item 
android:drawable="@drawable/list_normal" 
android:state_selected="false" 
android:state_pressed="false" /> 

<item 
android:drawable="@drawable/list_pressed" 
android:state_selected="false" 
android:state_pressed="true" /> 

<item 
android:drawable="@drawable/list_pressed" 
android:state_selected="true" /> 

</selector> 

 android:divider="@drawable/list_line" 就是每项之间的横线

可以找个横线图片
