I want to put custom border around zxing capture screen (camera screen). What modification would I need to make for this? Which activity and layouts would I need to change
This question already has an answer. But if someone needs how to draw a border around capture screen, here is the code. inazaruk's answer is correct. My answer is just an extension for that.
//initialize new paint in the constructor
Paint borderPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
borderPaint.setColor(ContextCompat.getColor(context, R.color.colorPrimary));
//inside onDraw
int distance = (frame.bottom - frame.top) / 4;
int thickness = 15;
//top left corner
canvas.drawRect(frame.left - thickness, frame.top - thickness, distance + frame.left, frame.top, borderPaint);
canvas.drawRect(frame.left - thickness, frame.top, frame.left, distance + frame.top, borderPaint);
//top right corner
canvas.drawRect(frame.right - distance, frame.top - thickness, frame.right + thickness, frame.top, borderPaint);
canvas.drawRect(frame.right, frame.top, frame.right + thickness, distance + frame.top, borderPaint);
//bottom left corner
canvas.drawRect(frame.left - thickness, frame.bottom, distance + frame.left, frame.bottom + thickness, borderPaint);
canvas.drawRect(frame.left - thickness, frame.bottom - distance, frame.left, frame.bottom, borderPaint);
//bottom right corner
canvas.drawRect(frame.right - distance, frame.bottom, frame.right + thickness, frame.bottom + thickness, borderPaint);
canvas.drawRect(frame.right, frame.bottom - distance, frame.right + thickness, frame.bottom, borderPaint);
