How to use relativelayout.setBackgroundDrawable() with a bitmap?

Question

I have a RelativeLayout object and want to dynamically change the background image with a dynamically created Bitmap object (it changes its color dynamically).

I saw that when I wanted to update the background image of the RelativeLayout object that I can only choose setBackgroundDrawable() which requires a Drawable object as a parameter.

My question is, how can I convert the dynamically created Bitmap object into a Drawable object?

Answer 1

BitmapDrawable(obj) convert Bitmap object into drawable object.

Try:

RelativeLayout relative = (RelativeLayout) findViewById(R.id.relative1);
Drawable dr = new BitmapDrawable(bit);
(view).setBackgroundDrawable(drawable);

I hope this will help you.

Answer 2

You can do it by this way

Drawable drawable = new BitmapDrawable(bitmap);
RelativeLayout r;
r = (RelativeLayout) findViewById(R.id.relativelayout1);
ll.setBackgroundDrawable(drawable);
