How to convert a Drawable to a Bitmap?

Question

I would like to set a certain Drawable as the device's wallpaper, but all wallpaper functions accept Bitmaps only. I cannot use WallpaperManager because I'm pre 2.1.

Also, my drawables are downloaded from the web and do not reside in R.drawable.

Answer 1

public static Bitmap drawableToBitmap (Drawable drawable) {     Bitmap bitmap = null;      if (drawable instanceof BitmapDrawable) {         BitmapDrawable bitmapDrawable = (BitmapDrawable) drawable;         if(bitmapDrawable.getBitmap() != null) {             return bitmapDrawable.getBitmap();         }     }      if(drawable.getIntrinsicWidth() <= 0 || drawable.getIntrinsicHeight() <= 0) {         bitmap = Bitmap.createBitmap(1, 1, Bitmap.Config.ARGB_8888); // Single color bitmap will be created of 1x1 pixel     } else {         bitmap = Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);     }      Canvas canvas = new Canvas(bitmap);     drawable.setBounds(0, 0, canvas.getWidth(), canvas.getHeight());     drawable.draw(canvas);     return bitmap; } 

Answer 2

This piece of code helps.

Bitmap icon = BitmapFactory.decodeResource(context.getResources(),                                            R.drawable.icon_resource); 

Here a version where the image gets downloaded.

String name = c.getString(str_url); URL url_value = new URL(name); ImageView profile = (ImageView)v.findViewById(R.id.vdo_icon); if (profile != null) {     Bitmap mIcon1 =         BitmapFactory.decodeStream(url_value.openConnection().getInputStream());     profile.setImageBitmap(mIcon1); }
