We take a string parameter in the show() method.Ĭreate a new class named MyReceiver.java. This class is extended to the BroadcastReceiver class. This example demonstrates how do I pass values between fragments in android. Here we are creating an interface and defining a method named show.

You can learn the Interface by clicking hereĬreate a new project in android studio and select an empty activity. Lets start with the development: Open Android Studio and create a new. So the technique is very similar to send data to activity. The interface is one efficient technique to pass data from one class to another class. In android, when we are working on a large project, most of the time we need to pass data from one activity to another activity or one fragment to another fragment. SetArguments setArguments () is a method to set bundle data over fragment. Intent intent new Intent( this, MyActivity.
In this article, we are going to learn how to pass data using the interface in android. Passing data to activity using the putExtra() directly on the intent.
