Question

Just getting started with Android development and Java. So, here’s the code I’m working with:

package com.example.helloandroid;

import android.app.Activity;
import android.os.Bundle;

public class HelloAndroidActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }
}

What is the purpose of declaring the onCreate() method here:

public void onCreate(Bundle savedInstanceState) {

Then using super to call the onCreate() method here:

super.onCreate(savedInstanceState);

Doesn’t this mean that you are calling the onCreate() method from the Activity class rather than the HelloAndroidActivity class? If so, what is the point of declaring a method with the same name in the HelloAndroidActivity class?

Thanks for any clarification.

Answer 1

onCreate is sort of your main(String[] args) function in normal Java. It is where you setup your code.
