double current_latitude,current_longitude;

    this.current_latitude=current_latitude;
    this.current_longitude=current_longitude;
}
public List<SuggestGetSet> getParseJsonWCF(String sName)
   {
    List<SuggestGetSet> ListData = new ArrayList<SuggestGetSet>();
    try {
       String temp=sName.replace(" ", "%20");
       URL js = new URL("");
       URLConnection jc = js.openConnection();
       BufferedReader reader = new BufferedReader(new InputStreamReader(jc.getInputStream()));
       String line = reader.readLine();
       JSONObject jsonResponse = new JSONObject(line);
       JSONArray jsonArray = jsonResponse.getJSONArray("category");
       for(int i = 0; i < jsonArray.length(); i++){
           JSONObject r = jsonArray.getJSONObject(i);
           ListData.add(new SuggestGetSet(r.getString("id"),r.getString("name")));
       }

回答1:

so you need full catids, so first change catid to array or list.

private List<String> catid=new ArrayList<String>();

then change your code

             String cats[]=acTextView.getText().toString().split(",");
             JsonParse jp=new JsonParse();
             for(String cat:cats){
                 List<SuggestGetSet> list =jp.getParseJsonWCF(acTextView.getText().toString());
              for(int i = 0;i<list.size();i++){
                if(list.get(i).getName().equals(cat))
                    catid.add(list.get(i).getId().toString());
                 //params.add(new BasicNameValuePair("parentid",list.get(i).getId()));


              } 
             }
