How to handle multiple intents on same activity?

Question

Okay, I simply want to have multiple intents passing data into a single activity which will summarise all the user inputs into a nice easy to read form.

This is for a mock up school application form.

The following code works fine but will produce two activities: One showing the student's gender and one showing the students name. How to get it to display both in the same activity? Pulling my hair out over this!!

XML of studentInfoActivity:

<android.support.constraint.ConstraintLayout

    String studentFullName = sfnBundle.getString("studentFullName");
    if (studentFullName != null) {
        TextView sfn = (TextView) findViewById(R.id.studentFullNameReviewScreen);
        sfn.setText(studentFullName);
    }
    else {
        TextView sfn = (TextView) findViewById(R.id.studentFullNameReviewScreen);

    }


    //Student Gender Reciever

}

}

You need only one Intent, you can put more than one extra to a intent. — Daniel Spiess, Apr 04 '19 at 10:54

Well you have a lot of mistakes such as incorrect class and method names.

You can pass as many as you want extra in one intent.

public void createCaregiverInfoSplash(View v){
    //Send Student Full Name
    EditText studentFullNameInput = (EditText) findViewById(R.id.studentFullNameInput);
    String studentFullName = studentFullNameInput.getText().toString();

    Spinner genderSpinner = (Spinner) findViewById(R.id.genderSpinner);
    String studentGender = genderSpinner.getSelectedItem().toString();

    Intent reviewIntent = new Intent(studentInfoActivity.this, reviewScreenActivity.class);
    reviewIntent.putExtra("studentFullName", studentFullName);
    reviewIntent.putExtra("studentGender", studentGender);
    startActivity(studentIntent);
}
