We start by creating an array of Integers in which we add the 3 colors present in the file colors.xml. The FirstFragment contains data needed to create our Spinner of colors. In our example we don't specify the type when we declare our ArrayAdapter but as this class is a template one we could have replaced Object objects with Integer objects in the constructor parameters.

We use Integer and not int type because we can't use primitive types, indeed Integer inherits from Object whereas int doesn't. Within we're going to fill an array of Integers (list of colors) and use this array to display every element (color) in this array. We have then the BaprogArrayAdapter which is a class that extends the Android ArrayAdapter. The MainActiviy is quite simple and so easy to understand. Spinner, Object class and 2's complement will be see in this example. The minimum SDK for this tutorial is the API 14 (Android 4.0 or also known as IceCreamSandwich). In this Android Spinner tutorial we're going to create our own cutom Spinner by replacing classic texts with squares of color. Here we will use custom adapters so as to fill customize data with images in spinner.With Android we haven't a classic ComboBox like in other frameworks but we have instead a Spinner.Īctually it's exactly the same and only the name differs.

Now to fill the data in this spinner we need to use one of the adapter class. In above code snippet we implement a simple spinner in our xml file. Important Note: Spinner is associated with Adapter view so to fill the data in spinner we need to use one of the adapter class. It provides a easy way to select a value from a list of values. In a default state, a spinner shows its currently selected value. Android spinners are nothing but the drop-downlist seen in other programming languages. In Android, Spinners provides you a quick way to select one value from a set of values. For more clarification about how’s an custom adapter implemented firstly we need to understand spinner. Here we create a custom list using the overrided functions of adapter and display custom spinner. For customization we need to create a custom adapter class and then extends our default adapter in that class. creating more custom list) then we have to implement a custom adapter like base adapter. In Android, Whenever we need to display a spinner item with image, text etc (i.e.
