Android- Adding items to spinner from listview

Question

I'm trying to add items from list-view into spinner.My first Activity contains list-view. I'm using button each time which is inserted a new row entry using SQLite database in my activities ListView and every row add in list-view properly. And another I have spinner in second Activity.

And I want to add each list_view items into spinner in second Activity.

This is my Product List Adapter class:

 public class Product_List_Adapter extends BaseAdapter
    {
        @SuppressWarnings("unused")
        private Context mContext;
        private ArrayList<String> Productid_ArrayList;
        private ArrayList<String> ProductName_ArrayList;
        private ArrayList<String> ProductDescription_ArrayList;


        public Product_List_Adapter(Context mContext,
                ArrayList<String> productid_ArrayList,
                ArrayList<String> productName_ArrayList,
                ArrayList<String> productDescription_ArrayList)
        {
            super();
            this.mContext = mContext;
            Productid_ArrayList = productid_ArrayList;
            ProductName_ArrayList = productName_ArrayList;
            ProductDescription_ArrayList = productDescription_ArrayList;
        }




        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return Productid_ArrayList.size();
        }

        @Override
        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return position;
        }

        @Override
        public long getItemId(int position) {
            // TODO Auto-generated method stub
            return position;
        }

        @Override
        public View getView(int pos, View child, ViewGroup parent) {
            // TODO Auto-generated method stub
            Holder mHolder;
            LayoutInflater layoutInflater;

            if(child == null)
            {
                layoutInflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
                child = layoutInflater .inflate(R.layout.define_products_listrow, null);
                mHolder = new Holder();
                mHolder.txt_product_id = (TextView)child.findViewById(R.id.txt_ProductId);
                mHolder.txt_product_name = (TextView)child.findViewById(R.id.txt_ProductName);
                mHolder.txt_product_description = (TextView)child.findViewById(R.id.txt_ProductDescr);

                child.setTag(mHolder);
            }
            else
            {
                mHolder = (Holder) child.getTag();
            }

            mHolder.txt_product_id.setText(Productid_ArrayList.get(pos));
            mHolder.txt_product_name.setText(ProductName_ArrayList.get(pos));
            mHolder.txt_product_description.setText(ProductDescription_ArrayList.get(pos));

            return child;
        }

        public class Holder {
            TextView txt_product_id;
            TextView txt_product_name;
            TextView txt_product_description;
        }
    }

Answer 1

This is arrayList

ArrayList<HashMap<String, String>> rssItemList = new ArrayList<HashMap<String, String>>();  

This is asyncTask class

class loadStoreItems extends AsyncTask<String, Void, ArrayList<HashMap<String, String>>> {
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        rssItemList.clear();
    }

    @Override
    protected ArrayList<HashMap<String, String>> doInBackground(
            String... args) {
        // updating UI from Background Thread
        FeedDBHandler rssDb = new FeedDBHandler(getApplicationContext());

        // listing all RSSItems from SQLite
        List<RSSItem> rssList = rssDb.getAllItems();

        // loop through each RSSItem
        for (int i = 0; i < rssList.size(); i++) {

            RSSItem s = rssList.get(i);

            // creating new HashMap
            HashMap<String, String> map = new HashMap<String, String>();

            // adding each child node to HashMap key => value

            map.put(TAG_TITLE, s.getTitle());
            map.put(TAG_LINK, s.getLink());
            map.put(TAG_CATEGORY, s.getCategory());
            map.put(TAG_DESRIPTION, s.getDescription());
            map.put(TAG_PUB_DATE, s.getPubdate());
            // adding HashList to ArrayList
            rssItemList.add(map);

        }
        return rssItemList;
    }

This can be helpful to you.

You can go through this code.

Answer 2

Add content to ListView and then use the onItemClickListener for each ListItem Value. You can achieve your goal by below code.

Use this for your global variable instead of string array

Global Class

    class GlobalClass extends Application {
    public static List<String> myVal = new ArrayList<String>() ;
    }

HomeActivity

OnItemClickListener

    listView.setOnItemClickListener(new OnItemClickListener() {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            long id) {

         String clickedvalue =(String) parent.getItemAtPosition(position); 
         myVal.add(clickedvalue);

         }
    }); 
}

Now All Clicked Values will be in your ListArray.

and then you can send it to via ..

    intent.putParcelableArrayListExtra( "addresses", addyExtras );

I hope it helps.
