I can't seem to make this activity save the edittexts inputs so that when I go to the next activity, and come back to this one, it brings up the info you had entered, rather than just showing the activity with empty edittext fields.

can someone see what I'm doing wrong or what I should change to hopefully make it work. The .java file is listed first. The corresponding xml file is listed second.

Code:
//import android.R.color;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;

import android.view.MenuItem;
import android.view.View;
import android.view.View.OnKeyListener;

//import android.widget.EditText;
import android.widget.EditText;
