Question

How to achieve in android something like on_hover in css ? I want to images in buttons be more light when touch. I have those lightier images but I don’t know where to save them.

Answer 1

use this below selector.xml and put your image in your drawable folder.
call your button background as android:background=”@drawable/selector”.

<item android:state_pressed="true"
    android:drawable="@drawable/darkimage" >
</item>

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

<item android:drawable="@drawable/lighterimage" >
</item>
