Question

我是Xamarin世界的新手，我遇到了一个奇怪的问题。我的所有屏幕都在页面底部有一个导航栏，导航栏下方似乎有一段白色空间，如下所示：

这是模拟器的屏幕截图，蓝色部分是导航栏的底部，空白区域是我想要删除的空白区域。忽略黑色部分，使用绝对底部的按钮，这只是模拟器。

基本上，我想让Scroll进入这个空白区域。作为旁注，导航栏以编程方式添加，导航栏正上方的内容包含在滚动容器中。目前，我正在使用Galaxy安卓手机和模拟器设置为＆＃34; Android_Accelerated_Nougat＆＃34;。

这个问题可能是什么？我可以在可能的嫌疑人身上检查什么？这个问题有没有解决方法？
