Android studio button to new activity using bundle

Here's a step-by-step guide on how to create a button in Android Studio that starts a new activity using a Bundle:

Step 1: Create a new activity

In your Android project, go to File > New > Activity > Empty Activity. Name your activity, for example, SecondActivity.

Step 2: Create a Bundle

In your SecondActivity, create a Bundle object to pass data from the first activity:

Bundle bundle = new Bundle();
bundle.putString("key", "value");

Step 3: Create an Intent

In your SecondActivity, create an Intent object to start the activity:

Intent intent = new Intent(this, SecondActivity.class);

Step 4: Put the Bundle in the Intent

Add the Bundle to the Intent using the putExtras() method:

intent.putExtras(bundle);

Step 5: Start the activity

Start the activity using the startActivity() method:

startActivity(intent);

Step 6: Receive the Bundle in the second activity

In your SecondActivity, retrieve the Bundle using the getIntent() method:

Bundle bundle = getIntent().getExtras();

Step 7: Access the data in the Bundle

Access the data in the Bundle using the getString() method:

String value = bundle.getString("key");

Putting it all together

Here's the complete code for the button click listener in your first activity:

Button button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        Intent intent = new Intent(getBaseContext(), SecondActivity.class);
        Bundle bundle = new Bundle();
        bundle.putString("key", "value");
        intent.putExtras(bundle);
        startActivity(intent);
    }
});

And here's the complete code for the SecondActivity:

public class SecondActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);

        Bundle bundle = getIntent().getExtras();
        String value = bundle.getString("key");
        // Do something with the value
    }
}

That's it! When you click the button, the SecondActivity will be started with the Bundle containing the data.
