Customize Camera View for Android using zbar

Question

I am new in android development. My app should activate the camera to scan a QR code and decode it to a string. This works fine, but I have one more requirement: to present

I faced the same problem. The solution is simply add the CameraPrevie in your xml inside a frameLayout, and just after that the image you want to put on top of is.

eg.:

and populate it from your activity:

Camera mCamera = getCameraInstance();

ImageScanner scanner = new ImageScanner();
scanner.setConfig(0, Config.X_DENSITY, 3);
scanner.setConfig(0, Config.Y_DENSITY, 3);

CameraPreview mPreview = new CameraPreview(this, mCamera, null, autoFocusCallB);
FrameLayout preview = (FrameLayout)findViewById(R.id.cameraPreview);
 preview.addView(mPreview);
