Developing a databound listview in Ionic: A step-by-step guide

In the world of programming, each platform has its own way of handling lists. For example, Android uses RecyclerView, WPF uses ListView, and in Ionic, we have ion-list. If you have a list of strings like this:

Animals:string[] = ["Dog", "Cat", "Human", "Crab"];

How can you bind this list to an ion-list and display all four items? I attempted the following code but it didn't produce the desired result.

<ion-list [(ngModel)]="Animals"/>
</ion-list>

Answer №1

Give this code a try,

 <ion-list>
        <ion-item *ngFor="let item of Animals">
          {{item}}
        </ion-item>
      </ion-list>

Here is the string array in your component file,

Animals:string[] = ["Dog", "Cat", "Human", "Crab"];
