All other settings remain as default (not a Launcher Activity, not a Fragment, Package set to, Target Source Set is main).Ĭlick Finish and the Activity and associated layout is created. Select the Parent to be the first Activity, (the parent is the screen the app returns to when the back button is pressed). Set the properties for the new Activity, e.g.: Using the File menu or the context menu (commonly right-click) add a new Activity to the app via New and Activity. (See the Android Project Structure article to become familiar with project files). In the Project explorer tree in the Studio select the app folder. Start with a Basic Hello World Appįire up Android Studio and open the Hello World project (see Your First Android Java Program - Hello World! on how to create the Hello World app). This leaves only a small amount of code to be written to load a second screen from the first app screen. Studio handles most of the plumbing when adding a new activity to an app, performing tasks 1 to 3 automatically when an Activity is created using Studio's options. The app must tell Android to start the new screen.Android must be notified that the Activity exists, via the app's manifest file.An Activity class must be defined in a Java class file to handle the screen.The definition of the screen must be composed in a layout.To get a screen up and running in an app the following is required: This demonstrates the principles of starting a new User Interface (UI) screen, helping to understanding on how Android handles UI creation. Building on the simple example seen in Your First Android Java Program - Hello World! another screen containing a simple message is loaded from a button. If you are new to Android development it is often easier to see simple examples rather than decode the developers online documentation. Step 3 − Add the following code to src/MainActivity.java import a Second Android Activity From The First Step 2 − Add the following code to res/layout/activity_main.xml. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.
This example demonstrates how do I send an Intent to browser to open specific URL in android.
