set bitmap to background of ImageView with imageView.setImageBitmap method
Please Use the following line to set image background.
imageview.setBackground(getResources().getDrawable(R.drawable.uporder));
Here uporder is an image resource present in your drawablefolder.
try this..
Create drawable using bitmap & use setBackgroundDrawable(Drawable d) method for imageview.
Drawable d = new BitmapDrawable(getResources(),bitmap);
imageview.setBackgroundDrawable(d);
I have tested and it's done
I think you are getting Bitmap
So you have to convert Bitmap to BitmapDrawable
like
BitmapDrawable ob = new BitmapDrawable(getResources(), bitmap)
then just set bitmap with below function
imageView.setBackground(ob);
by this way you can do it..
Try following code to set your own bitmap as background.
Bitmap bitmap = ...;
ImageView imageView = ...;
Drawable drawable = new BitmapDrawable(getResources(), bitmap);
imageView.setBackground(drawable);
