如何在android中使用两个线程升级gridview，在xml布局中仅使用一个gridview
我在gridview中有一些项，这些项是从sqlite显示的。现在，我使用另一个线程从json webservice获取数据，并将数据存储在sqlite中。现在，我想在同一个网格视图中显示更新的项以及现有项如何在android中使用两个线程升级gridview，在xml布局中仅使用一个gridview,android,sqlite,Android,Sqlite,我在gridview中有一些项，这些项是从sqlite显示的。现在，我使用另一个线程从json webservice获取数据，并将数据存储在sqlite中。现在，我想在同一个网格视图中显示更新的项以及现有项 private void displayUpdate(String Bid) { Log.w("Update cALL","Executing Update"); System.out.println("aeqw cursor that
