1.Nuget引用AcrUserdialogs

    其中版本兼容性注意事项，

2.最终集中控件的使用代码如下

 1   public partial class MainPage : ContentPage
 2     {
 3         public MainPage()
 4         {
 5             InitializeComponent();
 6      
 7         }
 8         //返回值
 9         Action<LoginResult> OkAction = (LoginResult) =>
10         {
11             if (LoginResult.Ok==false)
12             {
13                 UserDialogs.Instance.Alert("退出", null, "确认");  //直接参数调用
14             }
15             else
16             {
17                 if (LoginResult.LoginText=="1" && LoginResult.Password=="1")
18                 {
19                     UserDialogs.Instance.Alert("登陆成功", null, "确认");
20                   
21                 }
22                 else
23                 {
24                     UserDialogs.Instance.Alert("登陆失败", null, "确认");
25                 }
26             }
27         };
28 
29         Action CancleAction = () =>
30         {
31             UserDialogs.Instance.Alert("退出", null, "确认");
32         };
33 
34         Action Action1 = () =>
35         {
36             UserDialogs.Instance.Alert("CESHI", null, "确认");
37         };
38 
39         private async void Button_Clicked(object sender, EventArgs e)
40         {
41             using (IProgressDialog progress = UserDialogs.Instance.Progress("Progress", null, null, true, MaskType.Black))
42             {
43                 for (int i = 0; i < 100; i++)
44                 {
45                     progress.PercentComplete = i;
46                     await Task.Delay(60);
47                 }
48             }
49 
50 
51             LoginConfig loginConfig = new LoginConfig();
52             loginConfig.Message = "登陆操作";

56             loginConfig.LoginPlaceholder = "123";
57             loginConfig.PasswordPlaceholder = "2343";
58             loginConfig.SetAction(OkAction);
59             UserDialogs.Instance.Login(loginConfig);
60 

               //actionsheet的使用
61             ActionSheetConfig actionSheetConfig = new ActionSheetConfig();
62             actionSheetConfig.Add("测试1",Action1);
63             actionSheetConfig.Add("测试1",Action1);
