In your Java activity, you can call the Kotlin activity using an Intent. Here’s an example…

    
        binding.myButton.setOnClickListener(view -> {
            Intent intent = new Intent(this, MainActivity.class);
            startActivity(intent);
        });
    

In the above code, MainActivity is Kotlin Activity.

Call Java Activity from Kotlin:

Calling a Java activity from a Kotlin activity is simple. Start by navigating to your Kotlin Activity, then within the onCreate() method, incorporate the following code snippet.

    
        binding.myButton.setOnClickListener {
            val intent = Intent(this, MainActivity2::class.java)
            startActivity(intent)
        }
    

Conclusion:

In conclusion, the seamless interaction between Java and Kotlin activities is a fundamental aspect of Android development. Whether calling a Java activity from Kotlin or a Kotlin activity from Java, the process involves creating and utilizing Intents. This bidirectional interoperability empowers developers to harness the strengths of both languages, fostering a flexible and collaborative environment for crafting robust Android applications.
