I am using xamarin.forms to do an app but,
for some reason, after I change this page, I turned the image bigger and added some grids, the gesturerecognizer stopped work only in iphone, in android it works normally...cam someone see the problem in this code? because, so far, I can't.
I am creating a page programatically because of the template that I need.
private void CriaTela()
{
int row = 0;
int column = 0;
gridtextura.RowSpacing = 5;
gridtextura.ColumnSpacing = 15;
lstCategorias = lstCategorias.OrderBy(o => o.nome).ToList();
foreach (var item in lstCategorias)
{
Grid GridContent = new Grid
{
RowSpacing = 0,
//BackgroundColor = Color.Pink,
VerticalOptions = LayoutOptions.FillAndExpand,
RowDefinitions =
{
new RowDefinition { Height = new GridLength(8, GridUnitType.Star) },
new RowDefinition { Height = new GridLength(2, GridUnitType.Star) }
}
};
var textura = new CachedImage();
textura.Source = "texturaCateg";
textura.HorizontalOptions = LayoutOptions.FillAndExpand;
textura.VerticalOptions = LayoutOptions.FillAndExpand;
textura.Aspect = Aspect.Fill;
GridContent.BindingContext = item;
Grid boxColorView = new Grid
{
RowSpacing = 0,
// BackgroundColor = Color.Pink,
VerticalOptions = LayoutOptions.FillAndExpand,
RowDefinitions =
{
new RowDefinition { Height = new GridLength(2, GridUnitType.Star) },
new RowDefinition { Height = new GridLength(8, GridUnitType.Star) }
}
};
boxColorView.Children.Add(new BoxView { Color = Color.FromHex(item.corFundo), VerticalOptions = LayoutOptions.FillAndExpand }, 0, 1 );
boxColorView.Children.Add(textura, 0, 1);
boxColorView.Children.Add(new BoxView { VerticalOptions = LayoutOptions.FillAndExpand }, 0, 0);
gridtextura.Children.Add(boxColorView, column, row);
gridtextura.Children.Add(GridContent, column, row);
//Qual categoria foi escolhida?
var CliqueCategoria = new TapGestureRecognizer();
CliqueCategoria.Tapped += (s, e) =>
{
CriaLoading();
var stacklayout = s as Grid;
categoriaEscolhida = (Categorias)stacklayout.BindingContext;
ChamaProdutos();
};
GridContent.GestureRecognizers.Add(CliqueCategoria);
GridContent.BackgroundColor = Color.Green;
if (item.imagem != null && item.imagem != "")
{
int initIndex = item.imagem.IndexOf(',');
string image = "";
image = item.imagem.Substring(initIndex + 1);
try
{
GridContent.Children.Add(new CachedImage { Source = ImageSource.FromStream(() => new MemoryStream(Convert.FromBase64String(image))), VerticalOptions = LayoutOptions.FillAndExpand }, 0, 0);
}
catch (Exception e)
{
GridContent.Children.Add(new CachedImage { Source = "error.png", VerticalOptions = LayoutOptions.FillAndExpand, HorizontalOptions = LayoutOptions.Fill, HeightRequest = 50, WidthRequest = 50 }, 0, 0);
}
}
GridContent.Children.Add(new Label { Text = item.nome, TextColor = Color.FromHex(item.corTexto), FontSize = Device.GetNamedSize(NamedSize.Micro, typeof(Label)), FontAttributes = FontAttributes.Bold, HorizontalTextAlignment = TextAlignment.Center, VerticalOptions = LayoutOptions.Start, HorizontalOptions = LayoutOptions.CenterAndExpand }, 0, 1 );
if (column == 0)
{
column = 1;
}
else
{
column = 0;
row++;
}
}
}
The problem was in xaml...The main grid was inside other grid...this other grid was creating the problem...I think maybe it was over the clicks
