当使用Xamarin时,处理方向变化的最佳或最可接受的方法是什么?在Xamarin中处理页面方向变化
我有一个旋转木马页面,它旋转了5个内容页面(相同的页面,只是不同的文本/图像),在内容页面我有一个6行网格,每行包含图像,文本或按钮。
当从纵向更改为横向时,我在OnSizeAllocated中重置了这些尺寸和填充。这似乎对5个内容页面中的3个随机地工作,其他2个页面中的文本将失去位置,并且它并不总是相同的3。
我猜测有比手动调整大小的东西更好的方法吗?
protected override void OnSizeAllocated(double width, double height)
{
base.OnSizeAllocated(width, height); //must be called
if (this.width != width || this.height != height)
{
this.width = width;
this.height = height;
//reconfigure layout
if (width > height)
{
img.HeightRequest = 62.5;
img.WidthRequest = 62.5;
logo.HeightRequest = 52.5;
logo.WidthRequest = 142.27;
headerStack.Padding = new Thickness(0, -60, 0, 0);
txtStack.Padding = new Thickness(20, -60, 20, 0);
sIndicator.Padding = new Thickness(20, 0, 20, 100);
sButton.Padding = new Thickness(0, -40, 0, 0);
}
else
{
img.WidthRequest = 250;
img.HeightRequest = 250;
logo.HeightRequest = 70;
logo.WidthRequest = 189.7;
headerStack.Padding = new Thickness(20, 40, 20, 0);
txtStack.Padding = new Thickness(20, 0, 20, 0);
sIndicator.Padding = new Thickness(20, 25, 20, 0);
}
}
}
