android - Searchview searches only whole words instead searching in content -

i have searchfield searches in arrayadapter

   inputsearch.addtextchangedlistener(new textwatcher() {          @override         public void ontextchanged(charsequence cs, int arg1, int arg2, int arg3) {             zt.this.adapter.getfilter().filter(cs);           }          @override         public void beforetextchanged(charsequence arg0, int arg1, int arg2,                 int arg3) {           }          @override         public void aftertextchanged(editable arg0) {          }     }); 

it searches whole word. example:

baloon 

seach bal returns baloon, searching oon returns nothing. , he'll return baloon in case.

thanks helping.

you can use filterqueryprovider , pass adapter.setfilterqueryprovider().

adapter.setfilterqueryprovider(new filterqueryprovider() {     public cursor runquery(charsequence constraint) {         string s = '%' + constraint.tostring() + '%';         return getcontentresolver().query(contactscontract.commondatakinds.phone.content_uri,              new string[] {phone._id, phone.display_name, phone.number},             phone.display_name + ' ? or ' + phone.number + ' ?',             new string[] { s, s },             null);     } }); 

use adapter.
