Question

Hi i have a tab activity which show a list of items(ListView). This listview has a button in each row. I am handling this button clickListener in my custom adapter class which extends the BaseAdapter class. Now what i want is when i click on this button the item should be remove from the listview and listview should get a refresh. How to do this?

ok I think my code can explain it

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

    final ActivityManager am = (ActivityManager)context.getSystemService(Context.ACTIVITY_SERVICE);

    if(convertView==null) 
    {
             convertView = mInflater.inflate(R.layout.list_item, null);
             holder = new ViewHolder();
 //     holder.appSize = (TextView)convertView.findViewById(R.id.app_size);

              holder.appName = (TextView)convertView.findViewById(R.id.app_name);
              holder.app_icon = (ImageView)convertView.findViewById(R.id.app_icon);
              holder.button = (Button)convertView.findViewById(R.id.uninstall);
              if(kill_OR_uninstall)
              {

                       holder.button.setOnClickListener(new OnClickListener() {

                            public void onClick(View v) {

                       Intent intent = new Intent(Intent.ACTION_DELETE);
                       intent.setData(Uri.parse("package:"+package_names.get(position)));
                       context.startActivity(intent);



                     }
                    });
              }

              else
              {
                       holder.button.setText("End");
                       holder.button.setOnClickListener(new OnClickListener() {

                        public void onClick(View v) {
                        am.restartPackage(package_names.get(position));

                        }
                    });

              }

      convertView.setTag(holder);

    }

    else
    {       
                     holder = (ViewHolder) convertView.getTag();   
    }

     holder.appName.setText((String)app_details.get(position).get(APP_NAME));
     holder.app_icon.setImageDrawable((Drawable)app_details.get(position).get(APP_ICON));
  //   holder.appSize.setText(app_details.get(position).get(APP_SIZE)+ " KB");



     return convertView;

}

Based on the position of the row that was click remove an item from the Collection that is backing the Adapter example :

myArrayList.remove(position);

then notify the list that the data is changed using :

adapter.notifyDataSetChanged();
