Saving information in EditText in android

Question

I am trying to retain the data in my Edittext views, using onsaveinstancestate. The user clicks on the "add" button, which is supposed to retain the information in the Edittext views. When the add button is clicked, the user is taken back to activity main. When the module is selected for editing, the edit_module layout is shown but without the information in the edittext views, which I am trying to retain. Any ideas?? I think I may be missing a step, is there more to it than saving the strings in the onsaveinstancestate method, and then assigning those strings to the Edittext views when the activity is called?? New to Android.

NewModule.java

public class NewModule extends Activity{

// The EditText objects

EditText ModuleCode;
EditText ModuleName;
EditText ModuleType;
EditText DayOfWeek;
EditText StartTime;
EditText EndTime;
EditText Location;
EditText AdditionalInfo;


@Override
public void onCreate(Bundle savedInstanceState) {


      // Get saved data if there is any

    super.onCreate(savedInstanceState);
    dbTools = new DBTools(this);
    // Designate that add_module.xml is the interface used

    setContentView(R.layout.add_module);

    // Initialize the EditText objects
    ModuleCode= (EditText) findViewById(R.id.modcodeet);
    ModuleName = (EditText) findViewById(R.id.modnameet);
    ModuleType = (EditText) findViewById(R.id.moduletypeet);
    DayOfWeek = (EditText) findViewById(R.id.dowet);
    StartTime = (EditText) findViewById(R.id.starttimeet);
    EndTime = (EditText) findViewById(R.id.endtimeet);
    Location = (EditText) findViewById(R.id.locationet);
    AdditionalInfo = (EditText) findViewById(R.id.additionalinfoet);



}
public void addNewModule(View view) {

    // Will hold the HashMap of values 

    HashMap<String, String> queryValuesMap =  new  HashMap<String, String>();




    // Get the values from the EditText boxes

    queryValuesMap.put("ModuleCode", ModuleCode.getText().toString());
    queryValuesMap.put("ModuleName", ModuleName.getText().toString());
    queryValuesMap.put("ModuleType", ModuleType.getText().toString());
    queryValuesMap.put("DayOfWeek", DayOfWeek.getText().toString());
    queryValuesMap.put("StartTime", StartTime.getText().toString());
    queryValuesMap.put("EndTime", EndTime.getText().toString());
    queryValuesMap.put("Location", Location.getText().toString());
    queryValuesMap.put("AdditionalInfo", AdditionalInfo.getText().toString());

    // Call for the HashMap to be added to the database

    dbTools.insertModule(queryValuesMap);

    // Call for MainActivity to execute

    this.callMainActivity(view);


}
public void callMainActivity(View view) {
    Intent theIntent = new Intent(getApplicationContext(), MainActivity.class);
    startActivity(theIntent);
}   

public void onSaveInstanceState(Bundle savedInstanceState){


EditText editText = (EditText) findViewById(R.id.modcodeet);
String code = editText.getText().toString();
savedInstanceState.putString("code", code);


EditText editText2 = (EditText) findViewById(R.id.modnameet);
String name = editText2.getText().toString();
savedInstanceState.putString("name", name);

EditText editText3 = (EditText) findViewById(R.id.moduletypeet);
String type = editText3.getText().toString();
savedInstanceState.putString("type", type);


EditText editText4 = (EditText) findViewById(R.id.dowet);
String dow = editText4.getText().toString();
savedInstanceState.putString("dow", dow);

EditText editText5 = (EditText) findViewById(R.id.starttimeet);
String messagesubject = editText5.getText().toString();
savedInstanceState.putString("start", messagesubject);

EditText editText6 = (EditText) findViewById(R.id.endtimeet);
String end = editText6.getText().toString();
savedInstanceState.putString("end",end);

EditText editText7 = (EditText) findViewById(R.id.locationet);
String location = editText7.getText().toString();
savedInstanceState.putString("location", location);

 EditText editText8 = (EditText) findViewById(R.id.additionalinfoet);
String additionalinfo = editText8.getText().toString();
savedInstanceState.putString("additionalinfo", additionalinfo);

super.onSaveInstanceState(savedInstanceState);

}

Answer 1

try like this:

//intialization of shared preferences
private SharedPreferences preferences;

//in oncreate() give like this:
preferences = PreferenceManager.getDefaultSharedPreferences(this);

// store the edittext value in shared preferences
Editor edit = preferences.edit();
edit.putString("edittextvalue", edittextvalue);
edit.commit();

//whereever u want to get value and use
String apptext = preferences.getString("edittextvalue","");

Answer 2

use SharedPreferences to save edittext value
