Android: Is it possible to set overlay on camera if we use this code below?

Question

Intent i = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

mFileUri = getOutputMediaFileUri(MEDIA_TYPE_IMAGE);

i.putExtra(MediaStore.EXTRA_OUTPUT, mFileUri);

startActivityForResult(i, CAMERA_CAPTURE_PHOTO_REQUEST_CODE);

I am trying to add a button on Camera Overlay, but most tutorials out there create a camera file that extends SurfaceView implements SurfaceHolder.Callback. While that way is great for implementing a custom camera, I realize you have to rebuild some buttons for taking photos. Please Correct me if I'm wrong.

I want to use the Android default camera buttons and just add an overlay view for one button on top. Is it possible to do that? Like i.setOverlay(View v...); or something like that. Any help will be grateful. Thanks in advance.

Answer 1

Is it possible to do that?

No, because that is not your app. That is somebody else's app. You cannot modify the UI of somebody else's app from your app.
