How to use general settings in fragment on Android?

Question

I have a snippet and I want to keep the Facebook id in general preference. I cannot write private mode in the get preference function. And also I want to access these shared preferences in another snippet. How can i do this?

Here is my code ...

Session.openActiveSession(getActivity(), true, new Session.StatusCallback()
{
    @Override
    public void call(Session session,
                     SessionState state,
                     Exception exception) {

        if (session.isOpened()) {
            Request.executeMeRequestAsync(session,new Request.GraphUserCallback() {

                @Override
                public void onCompleted(GraphUser user, Response response) {

                    if (user != null) {
                        t = (TextView)rootView.findViewById(R.id.textView2);
                        p = (ProfilePictureView)rootView.findViewById(R.id.profilePictureView1);
                        p.setProfileId(user.getId());
                        s = user.getName();
                        t.setText(s);
                        s1 = user.getId();

                        private void SavePreferences(String key,String value)
                        {
                            SharedPreferences sharedPreferences = getPreferences(MODE_PRIVATE);
                            SharedPreferences.Editor editor = sharedPreferences.edit();
                            editor.putString(key, value);
                            editor.commit();
                        }

Answer 1

Use Shared Preferencesinside a Fragment; see below.

First write to SharedPreferences:

SharedPreferences pref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor edt = pref.edit();
edt.putString("facebook_id", id);
edt.commit();

Here id is a string containing the Facebook id you have, and 0 indicates private_mode.

-, Facebook, SharedPreference, Fragment:

SharedPreferences pref = getActivity().getPreferences(Context.MODE_PRIVATE);
String id = pref.getString("facebook_id", "empty");

, facebook_id null SharedPreference.

,

editor = getActivity().getSharedPreferences(MY_PREFS_NAME, Context.MODE_PRIVATE).edit();
                        editor.putString("yourtextvalueKey", test);
                        editor.commit();

prefs = getActivity().getSharedPreferences(MY_PREFS_NAME, Context.MODE_PRIVATE);
        text = prefs.getString("yourtextvalueKey", null);

• :

  public class Session {
  private static String PREF_NAME = "Memory";
  private static String FBID = "FBID ";
  public static boolean saveSessionId(String FBID , Context context) {
  Editor editor = context.getSharedPreferences(PREF_NAME, 0).edit();
  editor.putString(FBID , FBID);
  return editor.commit();
  }
  
  public static String getSessionId(Context context) {
  SharedPreferences savedSession = context.getSharedPreferences(
          PREF_NAME, 0);
  return savedSession.getString(FBID , null);
  }
  }

Answer 4

SavePreferences :

private static String MY_PREFS = "My_Preference";
private void SavePreferences(String key, String value) {
    SharedPreferences sharedPreferences = getActivity().getSharedPreferences(
            MY_PREFS, 0);
    SharedPreferences.Editor editor = sharedPreferences.edit();
    editor.putString(key, value);
    editor.apply();
}

Answer 5

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setHasOptionsMenu(true);
    getSharedPrefs();
}

private void getSharedPrefs() {
    sharedpreferences = getActivity().getSharedPreferences(
            Data.MY_PREFERENCES, Context.MODE_PRIVATE);

    // check for all to be loaded here
    boolean isValid = false;

    int posImage = 0;

    if (sharedpreferences.contains(Data.COLUMN_IMAGENUMBER)) {
        posImage = sharedpreferences.getInt(Data.COLUMN_IMAGENUMBER, 0);
        if (posImage >= 0 || posImage < Data.PICS.length) {
            isValid = true;
        }
    } else {
        isValid = false;
    }
}

@Override
public void onStop() {
    super.onStop();
    Editor editor = sharedpreferences.edit();
    editor.putInt(Data.COLUMN_IMAGENUMBER, cv.currentPuzzleImagePosition);
    editor.apply();
}

Answer 6

Try using this code. This is enough for this Shared preference, and it works either in work or in Fragment. Shared preferencecannot reflect or cannot affect activity or Fragment.
