I have a situation where I want to add an image view doing the same effect as this app
As you notice there is a drawable or something hiding the bottom side of the view adding a transparent gradient. How can I achieve the same effect?
Well, you can use fadingEdge attribute of the listView in your xml. Make a listView, then add items xml (images in particular as you've mentioned above).
android:fadingEdge="horizontal"
android:fadingEdgeLength="30dp"
android:fillViewport="false"
android:requiresFadingEdge="vertical"
