I am trying to make a if statement where it looks if the Edittext(number) is bigger then the int value. Doesnt Work

When I try to look if the Input of the edittext( number) is smaller than the int value, it says I can't compare an < to an EditText. My Value is an int and the Input is for numbers and how I understand is an int for a Number. So why can't I compare them? (If this is easy to solve, I have to say I am a beginner in Android Development)

Code:

package com.teamtreehouse.airport;

import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class AirPortActivity extends AppCompatActivity {

    private EditText nameTextView;
    private  EditText inputNumberAge;

    private Button nextActivityButton;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_air_port);

        nameTextView = (EditText)findViewById(R.id.nameeditText);
        inputNumberAge = (EditText)findViewById(R.id.inputNumberAge);






        nextActivityButton = (Button) findViewById(R.id.nextActivityButton);

        nextActivityButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Integer.parseInt(inputNumberAge.getText().toString()));
                String nameOfUser = nameTextView.getText().toString();
                int numberAge = 18;

                if (inputNumberAge > numberAge) {
                    Toast.makeText(AirPortActivity.this, "No Permission yet!", Toast.LENGTH_SHORT).show();
                }

                else




                startStory();
                String nameOfUserToast = "Hi " + nameOfUser;
                Toast.makeText(AirPortActivity.this, nameOfUserToast, Toast.LENGTH_SHORT).show();

            }
        });


    }

    private void startStory() {
        Intent intent = new Intent(this, AirPortSetup.class);
        startActivity(intent);
    }
}
