如何将加载覆盖进度条覆盖到android的“底部导航视图”（使用约束布局）

Question

我的id =“@ + id / loading_overlayView_main”constraintlayout打算覆盖整个屏幕“包括底部导航”

但事实并非如此。似乎android相对于底部导航视图调整它。

我的四个约束是这个

        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintBottom_toBottomOf="parent">

我该怎么设置布局约束？

我希望“@ + id / loading_overlayView_main”覆盖整个屏幕（包括底部导航视图）
