在第一个StackLayout中,我得到了只有3个元素的ListView。之后是很多空白,在PopUp的底部是另外两个StackLayouts。我尝试使用Margins,Padding,但没有任何变化。我不知道是什么问题。为什么会有那么多空间。底部的两个StackLayouts之间没有空格。如何解决这个空白?
<StackLayout VerticalOptions="End" Orientation="Horizontal" >
<Label Text="Check Default:" FontSize="18" />
<CheckBox IsChecked="False" Color="#006BE6" ></CheckBox>
但是,请注意如何将其包装在父堆栈布局中。由于没有高度要求,因此它仅遵循要求的高度。父堆栈布局是定义列表视图的布局。因此,它加载了列表视图,然后在底部(End)呈现了其他堆栈布局,确实造成了巨大的差距所以本质上:
<StackLayout VerticalOptions="End" Orientation="Horizontal" > <Label Text="Check Default:" FontSize="18" /> <CheckBox IsChecked="False" Color="#006BE6" ></CheckBox> </StackLayout> </StackLayout>
转到:
</StackLayout> <StackLayout VerticalOptions="End" Orientation="Horizontal" > <Label Text="Check Default:" FontSize="18" /> <CheckBox IsChecked="False" Color="#006BE6" ></CheckBox> </StackLayout>
