Question

我正在尝试实现布局，但是我无法获得正确的布局。当我的设备处于“纵向”模式并且使用constraint.Guideline时，我尝试找到正确的数字以将ORANGE FrameLayout底部放置在BottomNavigationView附近。如果我使用 app：layout_constraintGuide_percent =“。90” 靠近“正确”的数字，但我认为这是不正确的方法...也将设备置于横向模式时，ORANGE FrameLayout会消失要重新出现，我必须设置 app：layout_constraintGuide_percent =“。80” 。我是新手

当我在横向模式下旋转设备时，我遇到上面的相同问题以及 BottomNavigationView 的另一个问题，我想删除左右两边的空白（或替换为与BottomNavigationView的颜色相同）
