![]() We can define a string array in XML like we have shown below in the strings.xml file. ![]() But for this example, we will try the other way i.e. One by declaring an array and defining the items in it. To add items to the Spinner, there are two possible ways to provide it with a set of options. Once you will create that, the error in this file will be resolved.Īs you can see, we have one TextView and two Spinner views inside the xml file along with a few properties specified. NOTE: If you are getting an error in this, that is because you have not yet created the below data XML file. If you want, copy paste the below XML to start with this example in your local machine. So let's start, here we have the layout XML file. ![]() When user selects an optin from the second spinner too, then we will create a Toast and display the chosen values on screen. The first Spinner( classSpinner) holds the list of classes(in school) to be selected by the user and based on that choice we will assign the values to the second Spinner( divSpinner). But you can try and change the value of isVisible to VISIBLE to see if it is there or not. Hence, in the image below, it looks like it's not there. The second spinner has the property isVisible equals to GONE, which means it exists in the layout but it will not be visible(or it will be hidden). So we need to customize the layout(shown in below image) where one Spinner is placed below the TextView and the other spinner is below the first spinner.Īs the options inside the second Spinner will depend on what we select in the first Spinner, hence initially the second spinner will be hidden and it will only appear when user has selected one option from the first spinner. The main layout of the application will contain our one TextView and two spinners as its child component views. In this tutorial, we are going to create an application that works with two Spinners, which are inder-dependent. So let's checkout an example and learn how we can implement it in our Android App. You have already studied about what Spinners are and how they work. Android SDK Manager & required Packages.
