android custom view how to draw button on top of the view

I am creating a android app using LunarLander as a example. Now I need to create a few buttons which are drawn over the view. I do not want them as a seperate layout above or below the view but in the custom view. Is this possible or am I going to have to programmatically show the button images then detect the touch. The buttons I create using new never show on the app. I assume this is because I have overwritten the onDraw and the buttons are never drawn even though I call super.onDraw(canvas);

Answer 1

I think you could use FrameLayout to show two layers - first would be your surface from lunar, and second is the layout with buttons etc. You could define everything in layout.xml file. Probably that is enough.

Answer 2

If your view extends Linear/Relative/TableLayout, you can use view.bringChildToFront(child).

Answer 3

Use AbsoluteLayout & then in your ui thread set button.bringTioFront() & you are done! watch this post Problem when using more elements in the ListView

I would like to show a custom input field (specifically, one containing only 9-0 and two extra buttons containing decimal separator (, or .) and a delete button).

Is there a way to implement an input method and bind it to a specific input field? Thanks for the help!
