So i moved these lines to onPostExecute and it loads my page with the
appropriate number of rows, but nothing is populated.
In the "items" there are the 26 rows that should be returned, and now the
page loads 26 rows but no data is seen on the page.
protected void onPostExecute(Void result)
{
CustomListView adapter = null;
adapter = new
CustomListView(ViewInventoryActivity.this,R.layout.activity_view_listview_single,items);
list = (ListView)findViewById(R.id.list);
list.setAdapter(adapter);
if(this.dialog.isShowing()){
this.dialog.dismiss();
}
}
