How can I stick buttons to one another in TableLayout?

Question

1) How can I make all buttons stick to one another so that there is no space between any 2 buttons? 2) How can I make the picture of the bomb be inside the button as backround(I have it done wrongly) Here is some code how I added image:

clickedButton.setPadding(0,0,0,0);
        int newWidth = clickedButton.getWidth();
        int newHeight = clickedButton.getHeight();
        Bitmap originalBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.b64);
        Bitmap scaledBitmap = Bitmap.createScaledBitmap(originalBitmap, newWidth, newHeight, true);
        Resources resource = getResources();
        clickedButton.setBackground(new BitmapDrawable(resource, scaledBitmap));

Thank you very much!

To make them stick together I would try removing any possible margins, since you already tried padding. If it doesn't work I would try to work some negative values that might do what I wanted.

As for the images in the buttons, I think you could use ImageButton instead of button. Once it is clicked, it changes the background image (or not, I don't understand your game[?]).
