I want to create scanner screen (Image is given below).
For this screen, I aim to display a full-screen camera view where only the central 240x240 area is visible for scanning QR codes. Additionally, the remaining area should be displayed with 50% transparency to provide some visibility while keeping the focus on the central area.
Can anybody help me to create this kind of screen in android without using third party dependencies?
I have tried using CameraSource(com.google.android.gms.vision.Detector) and SurfaceView in layout.
In CameraView I can not find a method so that i can allow the scanning the particular area.
