search - Android Listview searching is not working properly -
kindly me in code, doesn't search perfect other values remain on position except search able string.
here code of filterable class

when search police no(policy# in code)
thank in advance :)
you can choose trick this, set textwatcher on edit text entering search text.
searchtext.addtextchangedlistener(new textwatcher() { @override public void ontextchanged(charsequence s, int start, int before, int count) { } @override public void beforetextchanged(charsequence s, int start, int count, int after) { } @override public void aftertextchanged(editable s) { string text = searchtext.gettext().tostring() .tolowercase(locale.getdefault()); lviewadapter.filter(text); } }); put filter method in adapter class
public void filter(string chartext) { chartext = chartext.tolowercase(locale.getdefault()); temp.clear(); if (chartext.length() == 0) { temp.addall(list_original); } else { (abc abc: list_original) { // if want search via policy if (abc.getpolicy().tolowercase(locale.getdefault()) .contains(chartext)) { temp.add(abc); } } } notifydatasetchanged(); } and create 2 abc type arraylists 1 temp , 1 original, pass data listview in getview method temp list, can make changes in temp, not original one. in above case temp list cleared first , run loop check search text in original list if matches add object temp list, , called notifydatasetchanged.. voila
