Starting Fragments/Communicating between fragments. Starting a new activity and passing some data. Using Parcelable and Serializable to pass objectsĪs the name says Intent is something that’s used to perform some action with respect to the flow of the android application. However, if you created the activity “by hand”, you will need to add its manifest element, and over time you will need to edit this element in many cases.In this tutorial, we’ll be discussing Android Intents and implement them using Kotlin in our application. If you used the new-activity wizard, this entry will be added for you. We also need to add it to our AndroidManifest.xml file. Simply having an activity implementation is not enough. Your new activity may need a new layout XML resource or other resources, which you would also have to create (or edit those created for you by the wizard). Once you have your stub activity set up, you can then add an onCreate() function to it (or edit an existing one created by the wizard), filling in all the details (e.g., setContentView()), just like you did with your first activity. This happens to be the wizard screen for the “Empty Activity” template other templates will have forms with other data to collect.Ĭlicking “Finish” will then create the activity’s Java or Kotlin class, related resources (if any), and manifest entry. What you see here will be based upon the template you chose. If you choose one of those templates, you will be presented with a one-page wizard in which to provide the details for this activity:Īndroid Studio New Android Activity Dialog This will give you a submenu of available activity templates. To use the Android Studio new-activity wizard, right-click a package (e.g., .activities in the project tree, and go into the “New” > “Activity” portion of the context menu. Use the Android Studio new-activity wizard. You need to create a new source file, containing a public class that extends Activity (or AppCompatActivity, etc.). To create your second (or third or whatever) activity, you first need to create the Java or Kotlin class. The same holds true for the third activity, the fourth activity, and so on. Given a module with one activity, if you want a second activity, you will need to add it yourself. On the positive side, this does help keep Android developers gainfully employed. 
Unfortunately, activities do not create themselves. Creating Your Second (and Third and…) Activity
