Question

Hi i have a class (MyCustomForm.xml) which i use as a LoginForm for the user.
Now i want to save and load the value from the username(EditText) from the LoginForm using SharedPreferences but i do not know how to set the value of username saved by SharedPreferences into the EditText in LoginForm(MyCustomForm.xml).

I was thinking to save the value in OnPause in my Main.xml and load the value through OnCreate in the class MyCustomForm.xml

Generaly i would like to use SharedPreferences globaly.

How would this look like?
Can somebody please help me to get on the right track?

It was thinking something like this Main.xml:

public class AndroidLogin extends Activity implements OnClickListener {

@Override     
protected void onPause() { 
   super.onPause();  
     Editor e = mPrefs.edit();
     e.putString(USERNM, username);
     e.commit();
}
}

Code MyCustomForm (LoginForm):

public class MyCustomForm extends Dialog {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(com.sencide.R.layout.inlogdialog);

    EditText userTest = (EditText)findViewById(R.id.txtUserName);
    userTest.setText(USERNM);
}
}

You can do something like this :

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(YouActivity.this);

String servername = settings.getString("sharedPreferencesKey", "defaultValue");
server.setText(servername);  // EditText

And you store data like this :

SharedPreferences.Editor editor = settings.edit();
editor.putString("server", "serverName");

EDIT :

This piece of code should do the trick for you :

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(context.getApplicationContext());
String servername = settings.getString("sharedPreferencesKey", "defaultValue");
