How to use Listactivity with Actionbar?

Question

You can only access a menu ListView who is without the ActionBar by the menu key in the emulator.

How to display it? It is necessary to inflate by BaseAdapter?

Activity of ListView:

public class ListDespesasActivity extends ListActivity {



@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);



    DespesaDAO despesa = new DespesaDAO(this);
    List<Despesa> list = despesa.getLista();
    ListView listView = getListView();
    setListAdapter(new DespesaAdapter(this,list,listView));


}


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_list_despesas, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()){
        case android.R.id.home:
            NavUtils.navigateUpFromSameTask(this);
            return true;
        case R.id.action_add_despesa:
            Intent intent = new Intent(this, EditaDespesaActivity.class);
            startActivity(intent);
            return true;
    }

    return super.onOptionsItemSelected(item);
}
}

BaseAdapter:

public class DespesaAdapter extends BaseAdapter {
private Context context;
private List<Despesa> lista;
private ListView listView;


public DespesaAdapter(Context context, List<Despesa> lista, ListView listView) {
    this.context = context;
    this.lista = lista;
    this.listView = listView;
}


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

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

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

@Override
public View getView(int position, View view, ViewGroup viewGroup) {
    final int auxPosition = position;




    LayoutInflater inflater = (LayoutInflater)
            context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);



    final RelativeLayout layout = (RelativeLayout)
            inflater.inflate(R.layout.row, null);


    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            Intent intent = new Intent(context, EditaDespesaActivity.class);
            intent.putExtra("valor", lista.get(auxPosition).getValor());
            intent.putExtra("data", lista.get(auxPosition).getData());
            intent.putExtra("descricao", lista.get(auxPosition).getDescricao());
            context.startActivity(intent);
        }
    });





    TextView data = (TextView)
            layout.findViewById(R.id.ddata);
    data.setText(lista.get(position).getData());

    TextView desc = (TextView)
            layout.findViewById(R.id.ddesc);
    desc.setText(lista.get(position).getDescricao());

    TextView valor = (TextView)
            layout.findViewById(R.id.vvalor);
    valor.setText(lista.get(position).getValor());

    return layout;
}
}

Answer 1

One Activity to have a Actionbar has to descend from Actionbaractivity, which is not the case Listactivity.

An Activity does not need to derive from Listactivity in order to use a Listview. The class Listactivity exists only to facilitate the use of Listview in a Activity.

So that your Actionbaractivity can handle a Listview needs a Layout containing a reference to and.

Declare a private field to store Listview

private ListView listView;

In the method onCreate get a reference to Listview and use the method ListView.setAdapter to pass an instance of DespesaAdapater

public class ListDespesasActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);

        //Layout que contem a ListView
        setContentView(R.layout.activity_main);

        DespesaDAO despesa = new DespesaDAO(this);
        List<Despesa> list = despesa.getLista();

        // O mesmos que ListView listView = getListView();
        ListView listView = (ListView)findViewById(android.R.id.list);

        //O mesmo que setListAdapter(new DespesaAdapter(this,list,listView));
        listView.setAdapter(new DespesaAdapter(this,list,listView));
    }
}

Now the Actionbaractivity is a "Actionbarlistactivity"

To interact with the Listview use the listview field:

listView.setOnItemClickListener(new OnItemClickListener()
{
    @Override
    public void onItemClick(AdapterView<?> a, View v,int position, long id) 
    {
        ....
        ....
     }
});

Although this solution is easy to implement, it would be advisable to use a Listfragment together with the Actionbaractivity
