Move Images from one screen to another Android

I'm having a problem with an application I'm creating. There is an application screen that takes data from parse.com, in the case an image, and wanted to pass it to another screen, but without losing quality. I even managed to move the image to another screen, but it comes with a very poor and erased quality. Is there no other way of receiving the image without losing quality? My code is this

public class Eventos extends ActionBarActivity {

ListView listview;
List<ParseObject> ob;
ProgressDialog mProgressDialog;
ListViewEventos adapter;
private List<GetEventos> eventos_lista = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.eventos);
    new RemoteDataTask().execute();
}

// RemoteDataTask AsyncTask
private class RemoteDataTask extends AsyncTask<Void, Void, Void> {
    @Override
    protected void onPreExecute() {
        super.onPreExecute();
        // Create a progressdialog
        mProgressDialog = new ProgressDialog(Eventos.this);
        // Set progressdialog title
        mProgressDialog.setTitle("Carregando Dados...");
        // Set progressdialog message
        mProgressDialog.setMessage("Aguarde...");
        mProgressDialog.setIndeterminate(false);
        // Show progressdialog
        mProgressDialog.show();
    }

    @Override
    protected Void doInBackground(Void... params) {
        // Create the array
        eventos_lista = new ArrayList<GetEventos>();
        try {
            // Localizando a classe noticias no parse.com
            ParseQuery<ParseObject> query = new ParseQuery<ParseObject>(
                    "Eventos");


            //colocando por ordem de data
            query.orderByAscending("Number");
            ob = query.find();
            for (ParseObject titulo : ob) {
                // Localizando as imagens na coluna foto do parse
                ParseFile image = (ParseFile) titulo.get("Foto");
                ParseFile img = (ParseFile) titulo.get("FotoEvento");

                GetEventos eventos = new GetEventos();
                eventos.setTitulo((String) titulo.get("Titulo"));
                eventos.setDescricao((String) titulo.get("Descricao"));
                eventos.setTextoEvento((String) titulo.get("TextoEvento"));
                eventos.setFoto(image.getUrl());
                eventos.setFotoEvento(img.getUrl()); //<<-Está é a imagem
                eventos_lista.add(eventos);
            }

        } catch (ParseException e) {
            Log.e("Error", e.getMessage());
            e.printStackTrace();
        }
        return null;
    }

    @Override
    protected void onPostExecute(Void result) {
        // Locate the listview in listview_main.xml
        listview = (ListView) findViewById(R.id.listViewEventos);
        // Pass the results into ListViewAdapter.java
        adapter = new ListViewEventos(Eventos.this,
                eventos_lista);
        // Binds the Adapter to the ListView
        listview.setAdapter(adapter);
        // Close the progressdialog
        mProgressDialog.dismiss();
    }
}

The listview adapter:

public class ListViewEventos extends BaseAdapter {

// Declare Variables
Context context;
LayoutInflater inflater;
ImageLoader imageLoader = new ImageLoader(context);
private List<GetEventos> eventos_lista = null;
private ArrayList<GetEventos> arraylist;

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

public class ViewHolder {
    TextView titulo;
    TextView descricao;
    ImageView foto;
}

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

@Override
public Object getItem(int position) {
    return eventos_lista.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.listview_eventos, null);
        // Locate the TextViews in listview_eventos.xml
        holder.titulo = (TextView) view.findViewById(R.id.TituloEvento);
        holder.descricao = (TextView) view.findViewById(R.id.DescricaoEvento);
        // Locate the ImageView in listview_noticias.xml.xml
        holder.foto = (ImageView) view.findViewById(R.id.ImgEvento);
        view.setTag(holder);
    } else {
        holder = (ViewHolder) view.getTag();
    }
    // Set the results into TextViews
    holder.titulo.setText(eventos_lista.get(position).getTitulo());
    holder.descricao.setText(eventos_lista.get(position).getDescricao());
    // Set the results into ImageView
    imageLoader.DisplayImage(eventos_lista.get(position).getFoto(),
            holder.foto);
    // 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, EventosAbrir.class);
            // Pass all data rank
            intent.putExtra("titulo",
                    (eventos_lista.get(position).getTitulo()));

            intent.putExtra("descricao",
                    (eventos_lista.get(position).getDescricao()));
            // Pass all data flag
            intent.putExtra("textoevento",
                    (eventos_lista.get(position).getTextoEvento()));


            intent.putExtra("fotoevento",
                    (eventos_lista.get(position).getFotoEvento()));
            // PEGA O ARRAY DE IMAGENS E ENVIA PARA A OUTRA TELA

            context.startActivity(intent);
        }
    });
    return view;
}

The activity that receives the data, including the image:

public class EventosAbrir extends ActionBarActivity {

String titulo;
String fotoevento;
String descricao;
String textoevento;
ImageLoader imageLoader = new ImageLoader(this);

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.eventos_abrir);

    Intent i = getIntent();
    // Get the result of rank
    titulo = i.getStringExtra("titulo");

    textoevento = i.getStringExtra("textoevento");
    // Get the result of country
    descricao = i.getStringExtra("descricao");

    //PEGA A FOTO QUE FOI PASSADA NA TELA ANTERIOR
    fotoevento = i.getStringExtra("fotoevento");


    TextView title = (TextView) findViewById(R.id.TituloAbrir);
    TextView desc = (TextView) findViewById(R.id.DescricaoAbrir);
    TextView txtevento = (TextView) findViewById(R.id.textoevento);

    ImageView imgflag = (ImageView) findViewById(R.id.abrir_foto);
    imgflag.setScaleType(ImageView.ScaleType.FIT_XY);

    // Set results to the TextViews
    title.setText(titulo);
    desc.setText(descricao);
    txtevento.setText(textoevento);

    // Capture position and set results to the ImageView
    // Passes flag images URL into ImageLoader.class
    //EXIBE A IMAGEM PASSADA NA TELA ANTERIOR
    imageLoader.DisplayImage(fotoevento, imgflag);
}

I notice that getStringExtra takes the photo event as String, does it have any influence?

EDITED

Solved the problem. The ImageLoader class loaded the images in 150x150 and the images I put in parse.com are 512x512 and by increasing the size of the imageview it lost quality. I changed the values in the ImageLoader class and now the images come with perfect quality.
