Label each row in the list

I am trying to set the ListViewdefault background image and highlighted background image for each individual line.

However, the highlighted background image affects individual lines, and the default background image affects the entire line ListView; but I need this to affect every line.

Can someone tell me how to do this?

This is my code:

layout /main.xml:

<ListView
 android:id="@+id/list"
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:dividerHeight="1dip"       
 android:listSelector="@drawable/bg_highlighted"
/>

hoods /selector.xml:

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

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

</selector>

SIC /main.java:

   ArrayAdapter<String> adapter = new ArrayAdapter<String>(
            this,R.layout.list, mStrings); /*"Item1","Item2","Item3","Item4"*/
    ListView lv = (ListView)findViewById(R.id.list);
    lv.setAdapter(adapter);
    lv.setBackgroundResource(R.drawable.selector);

As the default background and selected background, I use png images.

This is what I have , but this is what I want .

, , , ListView :

lv.setBackgroundResource(R.drawable.selector);

All you have to do is set this selector as the background of the root view inside yours layout/list.xml(the layout is overpriced for each item in the list)
