Question

I have to parse data from server to spinner. Now I want to delete some value from Spinner .

Here is my code .

mytaxList include all values. Now I want put check that if TaxType is compound delete TaxName and TaxValue of that type from spinner. Actually i donot want to display cound type tax in spinner. i.e i want to remove compound type tax from ArrayList mytaxList.

JSONObject taxes = returnTaxlist.getJSONObject(TAG_TAXES);

        Object tax ;

         if (taxes.optJSONArray("tax") != null){
                //The result isn't null so it is a JSONArray
                tax = taxes.optJSONArray("tax");
                }
                else
                {
                //The result is null so it isn't a JSONArray
                tax = taxes.optJSONObject("tax");
                }

                if (tax instanceof JSONObject){
                // The object is a JSONObject
                    tax =  taxes.getJSONObject(TAG_TAX);
                }

                    else
                     {
                // The object is a JSONArray

                    tax = taxes.getJSONArray(TAG_TAX);

                    mytaxList = new ArrayList<TaxList>();


                    for(int i = 0; i <=((JSONArray)tax).length(); i++)
                         {
                        if(i==0){
                            TaxList iTaxClass = new TaxList();
                             iTaxClass.setTaxId("");
                             iTaxClass.setTaxName("--Select--");
                             iTaxClass.setTaxType("");
                             iTaxClass.setTaxvalue("");
                             mytaxList.add(iTaxClass);

                             continue;

                        }

                          JSONObject taxlist = ((JSONArray)tax).getJSONObject(i-1);
                          TaxList iTaxClass = new TaxList();

                               //***** Storing each JSON item in variable
                         iTaxClass.setTaxId(taxlist.getString(TAG_TAX_ID));
                         iTaxClass.setTaxName(taxlist.getString(TAG_TAX_NAME));
                         iTaxClass.setTaxType(taxlist.getString(TAG_TAX_TYPE));
                         iTaxClass.setTaxvalue(taxlist.getString(TAG_TAX_VALUE));

                         mytaxList.add(iTaxClass);


                         } 

                            tax1 = (Spinner)findViewById(R.id.item1);
                            tax1.setAdapter(new TaxListAdapter(mytaxList,this));

                            tax1.setOnItemSelectedListener(new Spinner.OnItemSelectedListener() {

                             public void onItemSelected(AdapterView<?> parent, View selectedItemView, int position, long id) 
                             {

                                    TaxListAdapter taxlistvalue = (TaxListAdapter)parent.getAdapter();
                                    taxlistvalue.getItemId(position);

                        }

                        public void onNothingSelected(AdapterView<?> arg0) {


                        }
                    });

Answer 1

Before adding into ArrayList check this condition for Custom tax object, if it has add object into arraylist else no need to add.

if( taxlist.getString(TAG_TAX_NAME).equals("Normal") mytaxList.add(iTaxClass);
    mytaxList.add(iTaxClass);
