Converting a cardview to an image (bitmap)

Question

I have a CardView Layout with some views inside it. I want to convert that CardView(containing all views inside it) to an image.

• This layout is a dummy layout for demonstration purpose.

Here, the CardView cardfront , i want to convert that into an image bitmap and i want to show it in ImageView dummy .

I have checked a lots of, but none of them are working. And those are also depreciated. What are the new ways of achieving it.

(image)this layout to an image

Answer 1

use the below function to the get bitmap from cardview

protected Bitmap convertToBitmap(CardView view) {
    int totalHeight = view.getHeight;
    int totalWidth = view.getWidth();
    float percent = 0.7f;//use this value to scale bitmap to specific size

    Bitmap canvasBitmap = Bitmap.createBitmap(totalWidth,totalHeight, Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(canvasBitmap);
    canvas.scale(percent, percent);
    view.draw(canvas);

    return canvasBitmap;
}

use following to set bitmap as imageview background

imageview.setImageBitmap(canvasBitmap);

Answer 2

I hope you have tried converting a view to bitmap if not then here is code snippet below try this out and set the bitmap converted into the dummy image view

public static Bitmap getBitmapFromView(View view) {
    view.measure(MeasureSpec.UNSPECIFIED, MeasureSpec.UNSPECIFIED);
    Bitmap bitmap = Bitmap.createBitmap(view.getMeasuredWidth(), view.getMeasuredHeight(),
            Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    view.layout(0, 0, view.getMeasuredWidth(), view.getMeasuredHeight());
    view.draw(canvas);
    return bitmap;
}
