Xamarin.Forms菜鸟笔记--6.自定义无边框输入框Entry
Xamarin.Forms默认的Entry在ios下是四周圆角样式的输入框，在安卓下是底部横线
有时候我们想自定义输入样式，比如
官方给了自定义输入框的demo，传送门：https://docs.microsoft.com/zh-cn/xamarin/xamarin-forms/app-fundamentals/custom-renderer/entry
我们只需要稍微对demo修改一下就可以
// 这里不用改
public class MyEntry : Entry
{
}
ios下，修改BorderStyle 为空
using Xamarin.Forms.Platform.iOS;
[assembly: ExportRenderer (typeof(MyEntry), typeof(MyEntryRenderer))]
namespace CustomRenderer.iOS
{
public class MyEntryRenderer : EntryRenderer
{
protected override void OnElementChanged (ElementChangedEventArgs e)
{
base.OnElementChanged (e);
if (Control != null) {
Control.BorderStyle = UITextBorderStyle.None;
}
}
}
}
安卓没有设置border的方法，需要设置背景色为空即可
using Xamarin.Forms.Platform.Android;
[assembly: ExportRenderer(typeof(MyEntry), typeof(MyEntryRenderer))]
namespace CustomRenderer.Android
{
class MyEntryRenderer : EntryRenderer
{
public MyEntryRenderer(Context context) : base(context)
{
}
protected override void OnElementChanged(ElementChangedEventArgs e)
{
base.OnElementChanged(e);
if (Control != null)
{
Control.SetBackgroundColor(global::Android.Graphics.Color.Transparent);
}
}
}
}
