  @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;

        Log.i("checkeddddd","checkedddddd2222222233333333");
    }
    ViewHolder holder = (ViewHolder) view.getTag();

推荐答案

在获取视图，把第一个参数位置决赛。然后，你就可以从OnCheckListener得到它。然后，你可以在某些列表保存。并单击按钮时，通过列表循环和删除文件。

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.
