add buttons in front of javacameraview Android

Question

I have a javacameraview in my main activity. I would like to put some control buttons in front of the camera

<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.gustavo.tassio.opencvnativeandroid.Principal">

<org.opencv.android.JavaCameraView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:visibility="gone"
    app:show_fps="true"
    app:camera_id="any"
    android:id="@+id/cameraOpenCv"/>

JavaCameraView cameraView;
    cameraView = (JavaCameraView) findViewById(R.id.cameraOpenCv);
    cameraView.setVisibility(SurfaceView.VISIBLE);
    cameraView.setCvCameraViewListener(this);

it is like this now, just the pure image, my idea is to put the buttons on this scene

What do you mean in front? Can you post an image to see how it looks now? — Skizo-ozᴉʞS ツ, Apr 12 '18 at 22:48

If you add buttons to your framelayout, they will be displayed as you wish. The views in framelayout are displayed in chronological order. When you change visibility of a subview of a framelayout, it's order does not change, all subviews that you added after it either in xll or programmatically will be drawn "above".
