how to delete a particular file from the paticular folder in sdcard when click on check boxes in list view.

  @Override
  public View getView(final int position, View convertView, ViewGroup parent) {
    View view = null;
    if (convertView == null) {
        LayoutInflater inflator = context.getLayoutInflater();
        view = inflator.inflate(R.layout.rowbuttonlayout, null);
        final ViewHolder viewHolder = new ViewHolder();
        viewHolder.text = (TextView) view.findViewById(R.id.label);
        viewHolder.checkbox = (CheckBox) view.findViewById(R.id.check);
        viewHolder.imageView=(ImageView) view.findViewById(R.id.imageView1);
        viewHolder.imageView.setImageResource(R.drawable.ic_launcher);
        viewHolder.checkbox.setChecked(true);

        viewHolder.checkbox.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Log.i("checkeddddd","checkedddddd2222222233333333444444");
            }
        });


        viewHolder.checkbox
        .setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView,
                    boolean isChecked) {
                Model element = (Model) viewHolder.checkbox
                .getTag();
                element.setSelected(buttonView.isChecked());


                InterectiveArrayAdapter.this.remove(InterectiveArrayAdapter.this.getItem(position));
                //adapter.notifyDataSetChanged();
            //  list.remove(position);

                    Toast.makeText(getContext(), "Checked", 
                    Toast.LENGTH_SHORT).show(); 

            }
        });
        view.setTag(viewHolder);
        viewHolder.checkbox.setTag(list.get(position));


    } else {
        view = convertView;
        ((ViewHolder) view.getTag()).checkbox.setTag(list.get(position));

        Log.i("checkeddddd","checkedddddd2222222233333333");
    }
    ViewHolder holder = (ViewHolder) view.getTag();
    holder.text.setText(list.get(position).getName());

If you have path to the particular file then you can delete it by calling the below method().::

public boolean deleteFile(File path) {
    // TODO Auto-generated method stub
    if( path.exists() ) {
        return(path.delete());
      }
}

In get view, put the first param position as final. Then you will be able to get it from the OnCheckListener. Then, you can save it in some list. And when the button is clicked, loop through the list and delete files.

I can't follow you. If you have an index in a list, why can't you retrieve the file at that index in the list ??? – Snicolas Apr 04 '12 at 09:18
