OpenCV android camera preview with custom layout?
I want to add a button to the opencvcamera preview, but the button isnt visible and the Preview still fills the whole screen. Is there a way to make a custom layout where the OpenCV camera preview does not fill the whole scrren to display an additional button?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:opencv="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<org.opencv.android.NativeCameraView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:visibility="gone"
android:id="@+id/HelloOpenCvView"
opencv:show_fps="true"
opencv:camera_id="any" />
<Button
android:id="@+id/takepicture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" * Take Picture "
android:layout_gravity="bottom|right"
android:layout_margin="10px"
/>
</LinearLayout >
