Android search listview like dial pad search(search for both name and number) -

i created dial pad using grid view , got call log in list view, enabled search functionality call log user entered number(from gridview). how can search call log contact name also. suppose when user entered 7 showing call log containing 7 number, not showing call log containing letters p,q,r,s in contact name. have filter both same time.

dialerhomeactivity.java

calllistadapter=new customadapter(dialerhomeactivity.this, r.layout.list_row, common.calloglist);     /**      * enabling search filter      * */     // capture text in edittext     phone_num_edt.addtextchangedlistener(new textwatcher() {          @override         public void aftertextchanged(editable arg0) {             // todo auto-generated method stub             string text = phone_num_edt.gettext().tostring().tolowercase(locale.getdefault());             calllistadapter.filter(text);         }          @override         public void beforetextchanged(charsequence arg0, int arg1,                 int arg2, int arg3) {             // todo auto-generated method stub         }          @override         public void ontextchanged(charsequence arg0, int arg1, int arg2,                 int arg3) {             // todo auto-generated method stub         }     });
