How to save a fully rendered ScrollView to a Bitmap?

Question

Android

Here is the code:

public static Bitmap getBitmapFromView(View view, int totalHeight, int totalWidth) {
        Bitmap returnedBitmap = Bitmap.createBitmap(totalWidth,totalHeight , Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(returnedBitmap);
        Drawable bgDrawable = view.getBackground();
        if (bgDrawable != null)
            bgDrawable.draw(canvas);
        else
            canvas.drawColor(Color.WHITE);
        view.draw(canvas);
        return returnedBitmap;
    }

If I pass a ScrollView I get:

I pass the ViewGroup in which the ScrollView is contained I get:

Is there an option to save the ViewGroup with the ToolBar and the fully expanded ScrollView?

You forgot to call a method measure
Fix it like this:

public static Bitmap getBitmapFromView(View view, int totalHeight, int totalWidth) {
        Bitmap returnedBitmap = Bitmap.createBitmap(totalWidth,totalHeight , Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(returnedBitmap);
        Drawable bgDrawable = view.getBackground();
        if (bgDrawable != null)
            bgDrawable.draw(canvas);
        else
            canvas.drawColor(Color.WHITE);

        view.measure( View.MeasureSpec.makeMeasureSpec(totalWidth,View.MeasureSpec.EXACTLY),
                View.MeasureSpec.makeMeasureSpec(totalHeight,View.MeasureSpec.EXACTLY));
        view.layout(0,0,totalWidth,totalHeight);

        view.draw(canvas);
        return returnedBitmap;
    }
