OpenCV on Android focus on upper part

Question

I am using Open CV on Android studio. How can I focus on the upper part on the frame? I am using CameraBridgeViewBase. I tried to set cameraBridgeViewBase.setFocusable(true); and cameraBridgeViewBase.setFocusableInTouchMode(true);. Both does not work when I click to focus. I saw some said use parameters.setFocusMode(Parameters.FOCUS_MODE_AUTO);, but Camera Parameter class is deprecated.

Thank you.
