单击通知时显示调用本地通知的内容页

我如何获得通知以显示设置页面,例如单击通知时的“我的联系人”页面?

Xamarin.Forms 只有一个活动,无论你创建了多少个页面,它们都是在上面创建的 MainActivity .

但我们仍然可以找到解决方法:

1. 创建本地通知,以指示要导航到的页面( Page1 ):

   Notification.Builder builder = new Notification.Builder(Xamarin.Forms.Forms.Context);
   Intent intent = new Intent(Xamarin.Forms.Forms.Context, typeof(MainActivity));
   Bundle bundle = new Bundle();
   // if we want to navigate to Page1:
   bundle.PutString("pageName", "Page1");
   intent.PutExtras(bundle);
   PendingIntent pIntent = PendingIntent.GetActivity(Xamarin.Forms.Forms.Context, 0, intent, 0);
   builder.SetContentTitle(title)
          .SetContentText(text)
          .SetSmallIcon(Resource.Drawable.icon)
          .SetContentIntent(pIntent);
   var manager = (NotificationManager)Xamarin.Forms.Forms.Context.GetSystemService("notification");
       manager.Notify(1, builder.Build());
   

2. 在里面 MainActivity.cs 在…内 OnCreate 我们使用反射设置应用程序的 MainPage :

   protected override void OnCreate(Bundle bundle)
   {
       TabLayoutResource = Resource.Layout.Tabbar;
       ToolbarResource = Resource.Layout.Toolbar;
   
       base.OnCreate(bundle);
   
       global::Xamarin.Forms.Forms.Init(this, bundle);
       var myApp = new App();
       var mBundle = Intent.Extras;
       if (mBundle != null)
       {
           var pageName = mBundle.GetString("pageName");
           if (!string.IsNullOrEmpty(pageName))
           {
               //get the assemblyQualifiedName of page
               var pageAssemblyName = "Your_PCL_Name." + pageName+",Your_PCL_Name";
               Type type = Type.GetType(pageAssemblyName);
               if (type != null)
               {
                   var currentPage = Activator.CreateInstance(type);
                   //set the main page
                   myApp.MainPage = (Page)currentPage;
               }
   
           }
       }
   
       //load myApp
       LoadApplication(myApp);
   }
   

注意:此解决方法修改了 主页 你的PCL的 App ,如果您有此属性的用法,请正确修改逻辑。
