Create a Layout file that while show image for changing background and on it show TextView That will show Text and use below code to generate bitmap image and set it to your ImageView. Hope This will Help you
private Bitmap getCustomImage(#DrawableRes int imageId,String text) {
View customView = ((LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.your_layout_file, null);
ImageView imageView = (ImageView) customView.findViewById(R.id.imageView);
TextView textView = (TextView) customView.findViewById(R.id.textView);
textView.setText(text);
imageView.setImageResource(imageId);
customView.measure(View.MeasureSpec.UNSPECIFIED, View.MeasureSpec.UNSPECIFIED);
customView.layout(0, 0, customMarkerView.getMeasuredWidth(), customView.getMeasuredHeight());
customView.buildDrawingCache();
Bitmap returnedBitmap = Bitmap.createBitmap(customView.getMeasuredWidth(), customView.getMeasuredHeight(),
Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(returnedBitmap);
canvas.drawColor(Color.WHITE, PorterDuff.Mode.SRC_IN);
Drawable drawable = customView.getBackground();
if (drawable != null)
drawable.draw(canvas);
customView.draw(canvas);
return returnedBitmap;
}
