public class Test extends View {

    public Test(final Context context) {
        super(context);
    }

    public Test(final Context context, final AttributeSet attrs) {
        super(context, attrs);
    }

    public Test(final Context context, final AttributeSet attrs, final int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onVisibilityChanged(@NonNull final View changedView, final int visibility) {
        Log.d(TAG, " visibility=" + visibility);
        super.onVisibilityChanged(changedView, visibility);
    }
}

If I put this View in Activity, onVisibilityChanged work perfectly.

But if I put this View in Fragment, onVisibilityChanged() will not fire when fragment hidden.

Is there any solution if I don’t want to write the following in every Fragment?

override fun onHiddenChanged(hidden: Boolean) {
    super.onHiddenChanged(hidden)
    if (hidden) {
        //
    } else {
        //
    }
}
