What I want

My image already have transparency... The problem should be that I dont know a way to "Get a view under a view"

Answer 1

Use a FrameLayout parent to contain both views. Make the ListView fill the parent. Make the ImageView anchor to the bottom of the parent with layout_gravity ="bottom" and fill parent horizontally.

Make sure the ImageView is defined after the ListView so it will appear on top.

Answer 2

If i get you right, you have an imageView with transparent background but the canvas that the image is painted on has a white background.

So basically you just need to make sure that in the image view you give add the image with "src:" property.

and for transparent background use:

android:background="@android:color/transparent"
