Wait for Android Studio to finish creating your project, and then open app > res > layout > activity_main.xml. This file defines the layout for the user interface (UI).Ī UI in Android is defined in XML files. Open Android Studio and create a new project with an empty activity. Our membership form will be for a gym and will collect the following information: Consider the types of data you want to collect and choose the appropriate types of control. See the diagram below representing a standard application layout.īefore you begin the design process, you need to give some thought to what kind of data you want to collect from the user.

Whether you’re in charge of recruiting members for an app, an event, or a club, a simple and well-designed member registration form will speed up the registration process, hence encouraging more users to sign up. This tutorial walks you through the creation and use of a number of the most common controls for collecting data from the user.įor this tutorial, you will design and implement a membership registration form.
Probably is because ContentResolver.Android applications often rely upon data supplied by users.
