OnClicking Delete an Item from the ListView in Android

Question

I am trying to implement Delete functional to delete item from the listview. Click On the Text "Remove Item" Item should be removed from the ListView. I have tried but, I am getting an error in the code. I dont have any Idea of how to correct the errors.

Here is my code:

   public View getView(final int position, View convertView, ViewGroup parent) 
    {


      final  ViewHolder holder;

        if (convertView == null) 
        {
            convertView = inflater.inflate(R.layout.selecteditemlistview, null);
            holder = new ViewHolder();

            holder.textViewSelectedText = (TextView)convertView.findViewById(R.id.selectedtext);
            holder.price=(TextView)convertView.findViewById(R.id.selectitemprice);
            holder.image=(ImageView)convertView.findViewById(R.id.selectitemimage);
            holder.qty=(EditText)convertView.findViewById(R.id.selectqty);
            holder.total=(TextView)convertView.findViewById(R.id.price);

            holder.deleteButton = (TextView) convertView.findViewById(R.id.delete);


            convertView.setTag(holder);
        }
        else 
        {
            holder = (ViewHolder) convertView.getTag();
        }
        String amount=holder.qty.getText().toString();
        final Double price1=Double.parseDouble(itemprice.get(position));
        int qut=Integer.parseInt(holder.qty.getText().toString());
        Double total=(price1*qut);
        holder.textViewSelectedText.setText(arr1.get(position));
        holder.price.setText(itemprice.get(position));
        holder.image.setImageBitmap(itemimage.get(position));
        holder.total.setText(String.valueOf(total));

        final CartItem mCartItem = (CartItem) getItem(position);


        holder.mTextView.setText(mCartItem.product_name);
        holder.deleteButton.setOnClickListener(new OnClickListener() {


            public void onClick(View v) {
                Object cartItems;
                CustomAdapter myAdapter = new CustomAdapter(CustomAdapter.this, R.layout.selecteditemlistview, cartItems);
                ListView listview = (ListView) findViewById(R.id.delete);
                listview.setAdapter(myAdapter);
                        cartItems.remove(object);
                        myAdapter.notifyDatasetChanged();


            }

        });

        return convertView;     
    }

    class ViewHolder      
    {
         public TextView deleteButton;
         public TextView mTextView;

        TextView textViewSelectedText = null;
        TextView price=null;
        ImageView image=null;      
        EditText qty=null;
        TextView total=null;
    }  
    public class CartItem {
        public int id;
        public String product_name;
    }

The Exact error is in the below code:

     holder.deleteButton.setOnClickListener(new OnClickListener() {


            public void onClick(View v) {
                Object cartItems;
                CustomAdapter myAdapter = new CustomAdapter(CustomAdapter.this, R.layout.selecteditemlistview, cartItems);
                ListView listview = (ListView) findViewById(R.id.delete);
                listview.setAdapter(myAdapter);

                Object toRemove = arrayAdapter.getItem([POSITION]);
                arrayAdapter.remove(toRemove);

            }

        });

Please Help me to solve this problem. Thank you..

Answer 1

What you need is simply remove the dataset item from which you are populating your Adapter and then notify the adapter using notifyDataSetChanged()

        holder.deleteButton.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                 yourdataset.remove(position);
                 notifyDataSetChanged();
            }
        });
