NotifyDataSetChanged on gridview не работает - Android

Question

Я работаю с GridView. Я хочу обновить GridView на какой-то основе. Но метод notifyDataSetChanged() не работает.

Я выбираю таблицы на основе названия раздела. Когда я выбираю название раздела в первый раз, я получил таблицы этого раздела. Но когда я снова перейду к фрагментам разделов и выберите diff. чем я получаю только ранее выбранные таблицы. Это означает, что notifyDataSetChanged() не работает.

То, что я пробовал, как показано ниже.

Answer 1

Наконец я получил решение.

Я сделал, как показано ниже ...

Я поддерживая FLAG под названием getTableStatus, чтобы получить таблицы конкретного раздела. Если значение getTableStatus является FALSE, то вызывается только TableStatusAsync. При первом выборе раздела таблицы поступают из веб-службы, и эти таблицы вставляются в БД.

Во второй раз, выбрав СЕКЦИЯ, таблицы поступают из БД, а не из веб-службы. И таблицы поступают из БД из ранее выбранной СЕКЦИИ. Итак, нет ничего общего с notifyDataSetChanged().

Я только что изменил значение FLAG на FALSE, позвонив по номеру pref.setTableStatus(false); по выбору SECTION. Теперь, TableStatusAsync вызывается каждый раз, когда вы меняете свой выбор SECTION.

Модифицированный код ...

TableScreenSectionwiseActivity.java

@Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { pref.setSectionId(view.getTag().toString()); pref.setTableStatus(false); pref.setTableServiceStatus(false); Fragment fragment = new TableScreenActivity(); ReplaceFragment.getReplaceFragment(getActivity(), fragment, ""); }
