Java Saving and Retrieving Preferences

We want to save data and retry after.

First, save data, use this lines.

final String MYPREFS = "mySave";

int mode = Activity.MODE_PRIVATE;

SharedPreferences mySharedPreferences = getSharedPreferences(MYPREFS,mode);

SharedPreferences.Editor editor = mySharedPreferences.edit();

editor.putBoolean("isTrue", true);

editor.putFloat("lastFloat", 1f);

editor.putInt("Number", 2);

editor.putString("textEntryValue", "My String");

editor.commit();

To get data saved, use this lines, key value must be the same with key value saved.

final String MYPREFS = "mySave";

int mode = Activity.MODE_PRIVATE;

SharedPreferences mySharedPreferences = getSharedPreferences(MYPREFS,mode);

boolean isTrue = mySharedPreferences.getBoolean("isTrue",false);

float mfloat = mySharedPreferences.getFloat("lastFloat", 0f);

int number = mySharedPreferences.getInt("Number", 1);

String stringPreference = mySharedPreferences.getString("textEntryValue","");

Or we can do shortly.

final SharedPreferences.Editor edit = prefs.edit();

 edit.putInt("vi", 100);

 edit.commit();  
To get data.

SharedPreferences prefs;

prefs=PreferenceManager.getDefaultSharedPreferences(this);

int so = prefs.getInt("vi", 0);
