Android dynamically stacking views

Question

It seems that this issue is pretty confusing to me.

I just want a view to be added on click on top of another one. Something like this:

• View
• View
• View
• View

Does anyone know how to do this?

Answer 1

That depends on what "on top of another one" means.

If you mean on the Y axis (vertically up the screen), use a vertical LinearLayout .

If you mean on the Z axis (perpendicular to the screen, heading towards the user's eyes), use a FrameLayout or RelativeLayout , where later children are higher on the Z axis than are earlier children. Or, if your minSdkVersion is 21 or higher, you can use the elevation property to control the Z axis positioning.
