c# - Xamarin CarouselView Not Displayed -


i attempting use carouselview first time , kind of struck it. have xaml defined follows

<?xml version="1.0" encoding="utf-8" ?> <contentpage xmlns="http://xamarin.com/schemas/2014/forms"              xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"              xmlns:prism="clr-namespace:prism.mvvm;assembly=prism.forms"              prism:viewmodellocator.autowireviewmodel="true"              xmlns:cv="clr-namespace:xamarin.forms;assembly=xamarin.forms.carouselview"              x:class="csixty.xam.views.mainpage"              title="mainpage">     <contentpage.content>     <stacklayout>         <label text="name"  horizontaloptions="center" verticaloptions="centerandexpand"/>         <cv:carouselview itemssource="{binding zoos}">             <cv:carouselview.itemtemplate>                 <datatemplate>                     <label text="{binding name}" />                  </datatemplate>             </cv:carouselview.itemtemplate>         </cv:carouselview>     </stacklayout>     </contentpage.content> </contentpage>

the viewmodel has collection defined follows.

    public mainpageviewmodel()     {         zoos = new observablecollection<zoo>             {                 new zoo                 {                     name = "woodland park zoo"                 },                     new zoo                 {                     name = "cleveland zoo"                     },                 new zoo                 {                     name = "phoenix zoo"                 }             };      }

where zoo defined 

public class zoo {     public string name { get; set; } }

my issue carousel doesn't show up. empty. guide me ?

finally got working, thought share in case else runs same situation.

you need install nuget package in droid project (or whatever platform using) well. previously, had installed in portable library only.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
