Change Background Color Of Selected Item In ListView

Question

I have a ListView, I would like that each time i select an item in the listview, the background color changes to grey. If I select another element I want previous elements background to revert to white and the new item's background to be highlighted in grey

If you just want list items to change background color based on selection, that sounds like basic selector functionality. Create a selector xml file and set it as the background in your row xml.

Something like:

 < selector xmlns:android="http://schemas.android.com/apk/res/android">
    < item android:drawable="@android:drawable/myGreyColor" android:state_pressed="true"/>
    < item android:drawable="@android:drawable/myGreyColor" android:state_selected="true"/>
    < item android:drawable="@android:drawable/myWhiteColor"/>
    < /selector>
