android - Application crashes when searching data from listview using filterable -
i try write application library. have activity, see books in stock. use listview, , baseadapter. information saved in database.
oncreate in activity:

at time, writte in searchbar, , call function filter of baseadapter. application stops running, without anyting.

its not required set adapter on again in querytextlistener. if filter working, don't have except :
searchview.setonquerytextlistener(new searchview.onquerytextlistener() { @override public boolean onquerytextsubmit(final string s) { return false; } @override public boolean onquerytextchange(final string s) { bookshopshopeditionadapter.getfilter().filter(s); bookshopshopeditionadapter.notifydatasetchanged(); return false; } }); also don't need run asynctask in filter filtering.
