Is your item selected by a click? If it is you can use onItemClick from your listView — Francois Morier-Genoud, Jan 21 '14 at 09:05

I've managed to accomplish that by making several selectors for the different states

first put this in your listview

android:listSelector="@drawable/list_selector"

Then create xml files in drawable to control the diferent states

@drawable/list_selector

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/list_item_bg_normal" android:state_activated="false"/>
<item android:drawable="@drawable/list_item_bg_pressed" android:state_pressed="true"/>
<item android:drawable="@drawable/list_item_bg_pressed" android:state_activated="true"/>
</selector>

@drawable/list_item_bg_normal

<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
  android:startColor="@color/list_background"
  android:endColor="@color/list_background"
  android:angle="90" />
</shape>

@drawable/list_item_bg_pressed

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
  <gradient
      android:startColor="@color/list_background_pressed"
      android:endColor="@color/list_background_pressed"
      android:angle="90" />
</shape>

In your ListView Selection

listView.setOnItemClickListener(new OnItemClickListener() {

         @Override
         public void onItemClick(AdapterView<?> parent, View view, int position,long arg3) {
             view.setSelected(true);
             ...
         }
    }

Don't forget to add list_background_pressed and list_background to your values/color.xml or just set the color manually in each file.

And I Believe that when you use setSelection(int pos) that will automatically uset the layout you've set as selectected.

Hope it helps.

I've edited my code with setOnItemClickListener method, give it a check. — T.V., Jan 21 '14 at 10:18
Thanks! I'll try it! Correct me if I am wrong: function setSelection automatically calls onItemClick method of my list view? — bukka.wh, Jan 21 '14 at 10:22
Yes, I believe it does. Also check this post if you are not successful http://stackoverflow.com/questions/4800415/android-setselected-in-onitemclick-in-listview — T.V., Jan 21 '14 at 10:46

listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        if (updateview != null) updateview.setBackgroundColor(Color.TRANSPARENT);
        updateview = view;
        view.setBackgroundColor(Color.CYAN);
    }
});
