drawable To Bitmap

2   Hi Praveen. The drawable I want to set as the wallpaper is not in R.drawable. It is a drawable I downloaded from the web and keep it in an arrayList of type Drawable along with other drawables. –  Rob Jun 14 '10 at 8:37  1   i think you have the url values. then my edited answer should help. –  Praveen Jun 14 '10 at 8:49 where does str_url come from? I couldn't find any Drawable function related to strings... thanks for your help.–  Rob Jun 14 '10 at 9:08 4   I think I found something: if "draw" is the drawable I want to convert to a bitmap then: Bitmap bitmap = ((BitmapDrawable)draw).getBitmap(); does the trick! –  Rob Jun 14 '10 at 9:29  1   @Rob : if your Drawable is a BitmapDrawable only. (which means that your Drawable is but a wrapper around a Bitmap, actually) –  njzk2 May 28 at 11:47 show 1 more comments

public static Bitmap drawableToBitmap (Drawable drawable) { if (drawable instanceof BitmapDrawable) { return ((BitmapDrawable)drawable).getBitmap(); } Bitmap bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Config.ARGB_8888); Canvas canvas = new Canvas(bitmap); drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight()); drawable.draw(canvas); return bitmap; } share|improve this answer answered May 15 '12 at 12:33 André 2,2381921

8   This looks like the only answer that would work for any kind of drawable and also has a quick solution for a drawable that is already a BitmapDrawable. +1 –  Matt Wolfe Jun 6 '12 at 22:37 Add @Mauro's solution to this after the check for BitmapDrawable and you've got a very ideal solution with any/ all quicker solutions Incorporated. –  Tom Jul 4 '12 at 23:45 This solution works even if the drawable is a 9 patch image. –  Prakash Nadar Aug 15 '12 at 18:47 just one amendment: docs says about BitmapDrawable.getBitmap() that it may come back null. I say it may also come back already recycled. –  kellogs Sep 1 '12 at 21:20 7   Watch out: getIntrinsicWidth() and getIntrinsicHieght() will return -1 if drawable is a solid color.–  S.D. Oct 12 '12 at 13:51
