android editing shared preferences
by Prakash[ Edit ] 2014-03-31 16:22:07
Step 1:
Declare class variables :
// Shared Preferences
SharedPreferences pref;
// Editor for Shared preferences
Editor editor;
// Sharedpref file name
private static final String PREF_NAME = "EluthuPref";
// Context
Context _context;
// Shared pref mode
int PRIVATE_MODE = 0;
// All Shared Preferences Keys
private static final String IS_LOGIN = "IsLoggedIn";
// User name (make variable public to access from outside)
public static final String KEY_NAME = "name";
Step 2:
In the constructor, do as follow :
// Constructor
public MyClassname(Context context){
this._context = context;
pref = _context.getSharedPreferences(PREF_NAME, PRIVATE_MODE);
editor = pref.edit();
}
Step 3:
Use the edit function as follow :
/**
* Edit shared preferences
* */
public void editMyPreferences(){
// Storing login value as TRUE
editor.putBoolean(IS_LOGIN, true);
// commit changes
editor.commit();
}
This way using an editor you can edit the shared preferences in Android.
