    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    acTextView = (MultiAutoCompleteTextView) findViewById(R.id.autoComplete);
    acTextView.setAdapter(new SuggestionAdapter(this,acTextView.getText().toString()));
    acTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

   /* JsonParse jp=new JsonParse();
    List<SuggestGetSet> list =jp.getParseJsonWCF(acTextView.getText().toString());
    list.get(0).getId();*/

         }catch (JSONException e) {
             e.printStackTrace();

         return null;
    }

    // After completing background task Dismiss the progress dialog

    protected void onPostExecute(String file_url) {
        //dismiss the dialog once product deleted
        pDialog.dismiss();

        //parentcat.getText().clear();
}}

   try {
      JsonParse jp=new JsonParse();
      List<NameValuePair> params = new ArrayList<NameValuePair>();
      List<SuggestGetSet> list =jp.getParseJsonWCF(acTextView.getText().toString());
      for(int i = 0;i<list.length();i++){
        if(list.get(i).getName().equals(acTextView.getText().toString()))
         params.add(new BasicNameValuePair("parentid",list.get(i).getId()));
           break;
      }
