android - Returning # Of Items from ParseQueryAdapter -

i trying obtain amount of objects returned parsequeryadapter , put them in textview show user amount loaded.

i tried this, keeps displaying 0 though items loaded listview fine.

booksalesadapter = new booksalesadapter(this);         setlistadapter(booksalesadapter);      int booksalesamount = booksalesadapter.getcount();     string booksales = integer.tostring(booksalesamount);     textview salesamount = (textview) findviewbyid(r.id.textview_booksalesamount);     salesamount.settext(booksales); 

any ideas how go grabbing amount of items using parsequeryadapter rather running query?

this didn't seem work activity listview.

try using parsequeryadapter.onqueryloadlistener.

you can write code run after objects have been loaded adapter. there, should able fetch count.

before call setlistadapter():

booksalesadapter.addonqueryloadlistener(new parsequeryadapter.onqueryloadlistener<book>() {     @override     public void onloading() {}      @override     public void onloaded(list<event> events, exception e) {         // access item count through adapter's getcount() , update ui...     } });
