Help Please?Īlso, the reason i need a "response" or "action" from Spinner B is because, based on Spinner B's selection, it will display different data in the following Activity. By default, Android Spinner works like a Dropdown List or. So Spinner A, the Listener is working fine for, but it is not listening to spinner B. In Android, Spinner is a ViewGroup that allows the user to select a value from a list of values. I tested this by setting a Toast on All of Spinner B's selections, so when ever you select something in spinner B, you should get a toast, but that doesnt happen. In this video we will learn, how to create a custom spinner in Android Studio, which will display 1 ImageView and 1 TextView per list item. BUT, the problem i am having is that i cannot get the onItemSelectedListerner to work (i.e, it is only listening for selections from Spinner A, but any selections from spinner B are ignored). 2: Modify src/AndroidSpinnerExampleActivity.java file to create a simple list view with items which are showing as spinner items: 3: Modify res/layout/activitymain.xml file to add respective XML code. If the person changes their selection on Spinner A to Medicine, then Spinner B has to immediately change and show ONLY Medicine programs. You will use Android studio to create an Android application and name it as AndroidSpinnerExample under a package. So If Spinner A has I.T Selected, then Spinner B should show only I.T Programs. Now, Spinner B has to change based on Spinner A. So under I.T there are things link MIS, or DATABASE etc. Spinner B contains a list of Programs, which are under each "Major". But for this example, we will try the other way i.e. One by declaring an array and defining the items in it. Spinner A contains a list of "Majors" (e.g, I.T, Medicine, Vet) To add items to the Spinner, there are two possible ways to provide it with a set of options.
Now this is how this activity is supposed to work.
MultiSelectionSpinner.java public class MultiSelectionSpinner extends 7.widget.AppCompatSpinner implementsĭialogInterface.Firstly, i am a novice at android and java. As for the list item layout, we use Android's simple_spinner_item.xml.
Item.java package īelow is the initial code of our MultiSelectionSpinner class which consists of the variables I've mentioned before and the constructors. To make it easy, I use Lombok annotations. First, we create the Item class which has two variables, name and value. In this video we will create a simple spinner in Android Studio and fill it with a string array from our xml resource file.
