Run the application to launch Android emulator or you can run it on your mobile also(which is way faster).Copy the contents of res/layout/activity_main.xml and res/layout/activity_second.xml file.This will create both java file as well as the xml file for you For that right click on app, goto New, goto Activity, Empty activity and type in SecondActivity and click on OK. You will need to also create another Activity called SecondActivity.Open an Empty Activity and name it as MainActivity.Open Android Studio and create a new Android application and name it as “ExplicitIntent” and company domain as codedost so your package will be automatically set.Let me know if you want the other way also using Bundle. We can also send and retrieve values using Bundle, but I felt this is the easiest way to get you started with Intents. We are using getStringExtra as we want to display a string and not an integer, if we had an integer then getExtra would be fine. Now in order to retrieve these values in the SecondActivity you will need the method getStringExtra(key). The passing of parameters is done using putExtra method which is a key value tuple i.e putExtra(key, value). Coming straight to MainActivity.java file, here we will create a logic to check if username and password are valid, if valid then we send the username to the next activity using intent. By now, you should be able to understand the XML part, if yet do not understand some bit of it let me know. In the code below we will be going to another screen on successful login, and passing the username from login screen to the next screen(Activity). Explicit intent also helps to pass values from one activity to another. For example when we are on the login screen of any app, then on successful login you go on to another screen(Activity), this is nothing but explicit intent. Explicit intent helps us to call another activity in android. This Android program is to show username on next screen on successful login thereby demonstrating the use of explicit intent. testapp import import import android.os.Bundle import 7.app.Android program to implement explicit intentĪndroid program to implement explicit intent.
