Displaying two views at once

Question

I have a Game class which extends Activity:

public class Game extends Activity
...

in which I'm setting content view to XML layout, and just after that switching to my GamePanel class like this:

setContentView(R.layout.game_layout);
setContentView(new GamePanel(this));

In GamePanel class I need to update and draw objects on my layout game_layout. But my game_layout isn't showing because of switching to GamePanel.

How do I keep displaying first layout view and switch to class Gamepanel?

public class GamePanel extends SurfaceView implements SurfaceHolder.Callback
...

Is the question to put the Gamepanel inside the game layout like a smaller part of it? Or it isn't displaying at all? — dave, Mar 30 '16 at 16:11
I think you need fragments: http://developer.android.com/intl/es/guide/components/fragments.html — Miguel Benitez, Mar 30 '16 at 16:14
Gamepanel is overlaping whole screen (although I didn't set it any bg or something like that). So it's "displaying" (working). I need it to display over first layout, but transparently, if you know what I mean (just draw views on it over first layout). — johnyX, Mar 30 '16 at 16:15
setContentView means you are setting that as your Activity's content view. When you are calling `setContentView(new GamePanel(this))` you are changing the content that you previously set with `setContentView(R.layout.game_layout)`. If you want the `GamePanel` view to overlap the `R.layout.game_layout` not override it, you need to create the GamePanel view and add it to your contentView. Something like `this.findViewById(android.R.id.content).addView(new GamePanel(this))` — zgc7009, Mar 30 '16 at 16:17

If you want to display both views at the same time, try to add dinamically the GamePanel to the main layout view.

You have an example here Add view dinamically

In your code

setContentView(R.layout.game_layout);
setContentView(new GamePanel(this));

It overwrites game_layout by GamePanel. To make game_layout is the background you need to setup the GamePanel inside game_layout, i guest it is from game_layout.xml
