                android:visibility="visible">

            </ListView>

In addition to add android:drawSelectorOnTop="true" , you also need set a Drawable that should be used to highlight the currently selected item.

Two ways:

1. use android:listSelector xml attribute.

2. use setSelector method.

And you should create a selector xml in drawable folder like below:

<?xml version="1.0" encoding="utf-8"?>
   <selector xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:state_selected="true"   
         android:drawable="@color/gray" />
</selector>

suppose the name of this selector xml file is my_selector , then you could do like:

your_list.setSelector( R.drawable.my_selector);
