Multiautocompletetextview工作不正常(Multiautocompletete

我使用multiautocomplete TextView的在我的应用程序，这是我与mutltiautocompletetextview使用的项目是从JSON，现在只要用户选择多个值，我需要得到该项目的ID我想是的，我能得到第一项的ID只要，..

      "category":
   [
  {
  "id":"4",
  "name":"cat1"
  },
  {
  "id":"7",
   "name":"aditya"}
   ]
 }

JsonParse.java

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")));
       }
   } catch (Exception e1) {

                suggestions.clear();
                /*for (int i=0;i<new_suggestions.size();i++) {
                    suggestions.add(new_suggestions.get(i).getName());
                }*/

MainActivity.java

          JsonParse jp=new JsonParse();
              List<NameValuePair> params = new ArrayList<NameValuePair>();
              List<SuggestGetSet> list =jp.getParseJsonWCF(acTextView.getText().toString());
              for(int i = 0;i<list.size();i++){
                if(list.get(i).getName().equals(acTextView.getText().toString()))
                 params.add(new BasicNameValuePair("parentid",list.get(i).getId()));
                System.out.println("what goes"+params);
                catid=list.get(i).getId().toString();
              }

Answer 1:

所以你需要充分catids，所以第一个变化CATID到数组或列表。

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

然后改变你的代码

             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()));


              } 
             }
