I want to change list item color when selected or deselected and store all selected values in array

Question

How to select multiple list items in horizontal listview. I want to select multiple items in a list and store these values in an array.

        Async task to show sizelist

        @Override
        protected void onPostExecute(String result) {
            super.onPostExecute(result);
            if (dialog != null) {
                dialog.dismiss();
                dialog = null;
            }

            if (flag == 1) {

                sizeAdapter = new SizeAdapter(Product.this, arraysize, "fonts/GeosansLight.ttf");
                list_size.setAdapter(sizeAdapter);

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

Code to change selected item color in class HomeGS homeGS = arraysize.get(position);

                        if (homeGS.getSelected()) {

                            homeGS.setSizeProduct(homeGS.getSizeProduct());
                            homeGS.setSelected(false);


                        } else {
                            homeGS.setSizeProduct(homeGS.getSizeProduct());
                            homeGS.setSelected(true);
                        }

                        arraysize.set(position, homeGS);
                        sizeAdapter.notifyDataSetChanged();
                        size = arraysize.get(position).getSizeProduct();

                    }

                });


            } else if (flag == 0) {


            }

        }

    }

This is my Size Adapter code to change background and text color of selected item.

        if (oldData.get(position).getSelected()){

            holder.txt_name.setText(oldData.get(position).getSizeProduct());
            holder.txt_name.setBackgroundColor(Color.parseColor("#000000"));
            holder.txt_name.setTextColor(Color.parseColor("#ffffff"));

        }else {

            holder.txt_name.setText(oldData.get(position).getSizeProduct());
            holder.txt_name.setBackgroundResource(R.drawable.btn_border);
            holder.txt_name.setTextColor(Color.parseColor("#000000"));

        }
        return convertView;

    }

Make a bean class like this for your list

public class YourBean {

private String itemData;
private boolean checked;


public String getitemData() {
    return itemData;
}

public void setitemData(String itemData) {
    this.itemData= itemData;
}

public boolean isChecked() {
    return checked;
}

public void setChecked(boolean checked) {
    this.checked = checked;
}
}

Then make a arrayList like this

ArrayList<YourBean> listArray = new ArrayList<>();

Then make a custom adapter to make it the data list for your list

then if checkbox is checked set the checked boolean to true for that position like this

listArray.get(position).setChecked(true);

when you want to make another arraylist run a for loop for the listArray and check if the boolean is true or not, if its true then add it to another array list that you want to make.

I want to change list item color when selected or deselected and store all selected values in array
