更改网格XAMARIN

Question

我需要更改网格内按钮的大小...。

添加属性HightRequest和WidthRequest时，这不会在我的应用程序中进行任何更改。这为什么会发生？我应该怎么做才能修改网格上按钮的大小？

对我有帮助吗？

MyView.XAML：

 <StackLayout
            Padding="5">
            <SearchBar
                    Placeholder="Buscar..."              
                    BackgroundColor="White">
            </SearchBar>


            <Grid HorizontalOptions="FillAndExpand">
                <Grid.ColumnDefinitions>

您可以通过更改网格中ColumnDefinition的宽度来实现。 另外，第二行不在网格内，因为您只有一个RowDefinition。
