How To Save Dynamically Added Items In Listview With Sharedpreferences?

protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_mai

Solution 1:

You can save to shared preference in this way

SharedPreferencessp= context.getSharedPreferences(
            "file name", 0);
    SharedPreferences.EditorspEdit= sp.edit();
    spEdit.putLong(key, value);
    spEdit.commit();

Solution 2:

You are supposed to store single key-value paired data with SharedPreferences. Trying to store big grouped data is not efficient at all. You should use an SQLite database.

Solution 3:

You can store string sets in Shared Preferences, then convert them back to a List when you retrieve them.

ArrayList<String> list = newArrayList<String>();
list.add("test1");
list.add("test2");

PreferenceManager.getDefaultSharedPreferences(context)
    .edit()
    .putStringSet("stringset", newHashSet<String>(list))
    .commit();
