Go to another Activity from a list item with parse.com site data

Question

I would like to know how I could do to call another Activity, through a list item where the data is used from the site parse.com. For example, I have this code:

public class ListViewAdapterPizzarias extends BaseAdapter {

// Declare Variables

Context context;
LayoutInflater inflater;
ImageLoader imageLoader;
private List<WorldPopulation> worldpopulationlist = null;
private ArrayList<WorldPopulation> arraylist;

public ListViewAdapterPizzarias(Context context,
                                List<WorldPopulation> worldpopulationlist) {
    this.context = context;
    this.worldpopulationlist = worldpopulationlist;
    inflater = LayoutInflater.from(context);
    this.arraylist = new ArrayList<WorldPopulation>();
    this.arraylist.addAll(worldpopulationlist);
    imageLoader = new ImageLoader(context);
}

public class ViewHolder {

    TextView nome;
    TextView telefone;
    TextView endereco;
    TextView status;
}

@Override
public int getCount() {
    return worldpopulationlist.size();
}

@Override
public Object getItem(int position) {
    return worldpopulationlist.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

public View getView(final int position, View view, ViewGroup parent) {
    final ViewHolder holder;
    if (view == null) {
        holder = new ViewHolder();

        view = inflater.inflate(R.layout.item_lista_pizzarias, null);
        // Locate the TextViews in listview_item.xml
        holder.nome = (TextView) view.findViewById(R.id.nome);
        holder.endereco = (TextView) view.findViewById(R.id.endereco);
        holder.telefone = (TextView) view.findViewById(R.id.telefone);
        holder.status = (TextView) view.findViewById(R.id.status);
        view.setTag(holder);


    } else {
        holder = (ViewHolder) view.getTag();
    }
    // Set the results into TextViews

    holder.nome.setText(worldpopulationlist.get(position).getNome());
    holder.endereco.setText(worldpopulationlist.get(position).getEndereco());
    holder.telefone.setText(worldpopulationlist.get(position).getTelefone());
    holder.status.setText(worldpopulationlist.get(position).getStatus());


    ///teste
    // Listen for ListView Item Click
    view.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View arg0) {
            // Send single item click data to SingleItemView Class
            Intent intent = new Intent(context, MainActivity.class);

   //O que colocar aqui para buscar o dado do site parse.com e chamar a outra activity?

        }
    });
    return view;
}

}

It is not interesting that you perform this logic inside your Adapter. From your Listview you have the method setOnItemClickListener which is the best way to perform an action from clicking on a list item.

To start an Activity you need another Activity to create one Intent and use startActivity(), for example:

Intent i = new Intent(MyActivity.this, MyNewActivity.class);
startActivity(i);

If you are using your Listview in a Fragment use the method getActivity() to create Intent, for example:

Intent i = new Intent(getActivity(), MyNewActivity.class);
getActivity().startActivity(i);
