Android: Setting Background Image for RelativeLayout?

Question

I have downloaded an image at runtime. Now I want to set it as a background for RelativeLayout. Does it possible?

Answer 1

Check out the setBackgroundDrawable, or maybe createFromPath in the Drawable class.

   RelativeLayout rLayout = (RelativeLayout) findViewById (R.id.rLayout);
   Resources res = getResources(); //resource handle
   Drawable drawable = res.getDrawable(R.drawable.newImage); //new Image that was added to the res folder

    rLayout.setBackground(drawable);

Answer 2

Instead use:

View lay = (View) findViewById(R.id.rLayout);
lay.setBackgroundResource(R.drawable.newImage);

This works because R.drawable.newImage refers to an integer. So you could do:

int pic = R.drawable.newImage;
lay.setBackgroundResource(pic);
