在执行其他活动后如何保存EditText的值

Question

i have my first activity with two EditText fields with hint's as first name and last name, when ever i go to my second activity and return to my first activity by a widget button the EditText fields in my first activity gets reset.

SIMPLY i want my EditText fields to remain same in my first activity as i re-visit my first activity from my second activity.

MY MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);



}

public void onButton1Click(View v)
{

    Intent intent = new Intent (this,MainActivity2.class);
    startActivity(intent);

}

}

My MainActivity2.java

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main2);

}

}

SOLUTION - i changed my second activity to this. just added reference to my Button and applied an onClickListener with onBackPressed(); code.

    setContentView(R.layout.activity_main2);  

     Button button = (Button)findViewById(R.id.button3);   //gave reference of button in second activity
    button.setOnClickListener(new View.OnClickListener() {  //and applied an onClickListener with code onBackpressed();
        public void onClick(View v) {
            onBackPressed();
            // Code here executes on main thread after user presses button
        }
    });
}

Answer 1

Open secondActivity like below,

Intent i = new Intent(A.this,B.class);
startActivity(i);
finish();

to

Intent i = new Intent(A.this,B.class);
startActivityForResult(i,1);

do not open 1st Activity from 2nd Activity, just need to back press.

Answer 2

try this declare all variavle at top of activity

public static final String MyPREFERENCES = "MyPrefs" ;
public static final String FNAME = "fname";
public static final String LNAME = "lname";

SharedPreferences sharedpreferences;

write this code when you move to your next activity

sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);

// store login data in sharedpreferences
SharedPreferences.Editor editor = sharedpreferences.edit();
editor.putString(FNAME, edittext.getText());
editor.putString(LNAME, edittext2.getText());
editor.commit(); //save data in  sharedpreferences

write this code in your oncreate method after you bind your controls

and get data from sharedprefrence like this

String fname= prefs.getString(FNAME, "");
String fname= prefs.getString(LNAME, "");

than set it to your editext like this

editext.setText(fname);
editext2.setText(lname);

let me know in case of any query
