android - Duplicate value issue in MultiAutoCompleteTextView -

-

i new android development , using multiautocompletetextview in app , following code.

public textview autoselected; string[]    countries   =   {"india","usa","canada","indonesia","belgium", "france", "italy", "germany", "spain"}; @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);      multiautocompletetextview   autocompletetextview    =   (multiautocompletetextview)findviewbyid(r.id.autocompletetextview);           arrayadapter<string>    adapter     =   new arrayadapter<string>(this,android.r.layout.simple_dropdown_item_1line,countries);     autocompletetextview.setadapter(adapter);     autocompletetextview.settokenizer(new multiautocompletetextview.commatokenizer());   }

first problem , main problem textview getting duplicate values means same country showing in textview again , again. example: can select usa autocomplete n number of times , showing n times in text field.

i want if selected specific value suggestion, in case either should not visible in suggestions or should not visible in textview.

second issue

i want customize design of selected values in textview background , close sign attached it.
