How do I save the state of my activity

Question

How do I save the way my Activity is so when closed with the back button and resumed it will be the same way it was when closed.

this is my Activity code:

public class Levels extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setTheme(android.R.style.Theme_NoTitleBar_Fullscreen);
    setContentView(R.layout.levels);

    final EditText anstext1 = (EditText) findViewById(R.id.anstext1);
    Button button1 = (Button) findViewById(R.id.button1);

    button1.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {   
             String result = anstext1.getText().toString();
             if(result.equals("they"))
                 setContentView(R.layout.social);
             else 
               Toast.makeText(getApplicationContext(), "Wrong", Toast.LENGTH_LONG).show();
        }
    });
    }

}

In the onSaveInstanceState() method you can add your data into the bundle and then when the onCreate() is called you can grab those previous values from the bundle.

You can use onResume to restore the resources, and when Activity is dead, you can use properties to save resources and roll back.
