LinearLayout with nested RelativeLayout, order problem

I've got a problem with 2 dynamically created Layouts, the outer one being a LinearLayout which contains a relativeLayout and a Button (just for testing, will me more buttons soon).

My Relative Layout is basically a 9x9 arrangement of Buttons for a sudoku game.

My Problem now is the following, i want the relativeLayout on top of the Button, not below it. Following code places it below:

MainLayout lay = new MainLayout(this); // MainLayout is derived from RelativeLayout
LinearLayout outerLay = new LinearLayout(this);
outerLay.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
outerLay.setOrientation(LinearLayout.VERTICAL);
Button but = new Button(this);

outerLay.addView(but);
outerLay.addView(lay);

setContentView(outerLay);

This works perfectly fine, but if I rearrange them it like this:

outerLay.addView(lay);
outerLay.addView(but);

the button doesn't even show up. Anyone has a clue on this? (Same ha开发者_开发问答ppens to vertical btw.).

Greetings.

If your MainLayout lay is like :

setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));

Well there is no room on screen to display anything.

Your lay is too big. Check your layoutParams of it. I hope it will help you.
