Add buttons to the bar action when using Listactivity?

Question

Well I have an application that would like to keep the standard format on all screens, i have a quick access menu with some items in the action bar, and other complete in the menu option.

The problem is that as I am using the ListActivity This is not working. I do not understand very well this part of extensions, if someone has a good material that explains, in Portuguese please, I thank you.

My menu XML code:

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:yourapp="http://schemas.android.com/apk/res-auto"
    tools:context="com.example.starlighting.MainActivity" >

    <item
        android:id="@+id/menugerenceditar"
        android:icon="@drawable/editar"
        android:orderInCategory="1"
        android:title="Editar"
        app:showAsAction="ifRoom"/>

    <item
        android:id="@+id/menuadd"
        android:icon="@drawable/site"
        android:orderInCategory="2"
        android:title="Gerenciar"
        app:showAsAction="ifRoom"/>

    <item
        android:id="@+id/menuremov"
        android:icon="@drawable/site"
        android:orderInCategory="3"
        android:title="Importar"
        app:showAsAction="ifRoom"/>

    <item
        android:id="@+id/menuexportar"
        android:icon="@drawable/site"
        android:orderInCategory="4"
        android:title="exportar"
        app:showAsAction="ifRoom"/>

    <item
        android:id="@+id/menuimportar"
        android:icon="@drawable/site"
        android:orderInCategory="5"
        android:title="Star Lighting"
        app:showAsAction="ifRoom"/>

    <item
        android:id="@+id/menusair"
        android:icon="@drawable/sair"
        android:orderInCategory="100"
        android:title="Sair"
        app:showAsAction="ifRoom"/>

</menu>

My code of flater menu:

@Override

    if(featureId == Window.FEATURE_ACTION_BAR && menu != null){
        if(menu.getClass().getSimpleName().equals("MenuBuilder")){

                m.invoke(menu, true);
            } catch(NoSuchMethodException e){
            } catch(Exception e){
                throw new RuntimeException(e);
            }
        }
    }

    return super.onMenuOpened(featureId, menu);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    //getMenuInflater().inflate(R.menu.gerenciar, menu);
    getMenuInflater().inflate(R.menu.gerenciarescondido, menu);
    onMenuOpened(Window.FEATURE_ACTION_BAR, menu);
    return true;
}

//seta as opções de função dos itens do menu
@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.

    int id = item.getItemId();
    if (id == R.id.menugerenceditar) {
        //List<Lista> lista = gerarlista(tabbanco);

        //final Listaadapter listasadapter = new Listaadapter(this,  lista);
        //setListAdapter(listasadapter); 

        getListView().setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position,
                long id) {
            //Lista tabela = listasadapter.getItem(position);
            Intent intent = new Intent(gerenciar.this, gerenciartabela.class);
            //intent.putExtra("tabela", tabela.getNome());

        startActivity(intent);
        return true;
    }
    if(id==R.id.menuremov){
        return true;
    }
    if (id == R.id.menusair) {
        AlertDialog.Builder mensagem = 
                new AlertDialog.Builder(gerenciar.this);

        mensagem.setTitle("Atenção!");
        mensagem.setMessage("Deseja realmente sair?");
        mensagem.setIcon(R.drawable.sair);

        mensagem.setPositiveButton("Sim",new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog,int id) {
                gerenciar.this.finish();
            }});
        mensagem.setNegativeButton("Não",null);
        mensagem.show();
        return true;

    }
    if (id == R.id.menuexportar) {
        return true;
    }
    if (id == R.id.menuimportar) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

My code 'list'

        package com.example.app;
    public class Lista {

        private String nome;
    //    private int idade;
     //   private int imagem;


        public Lista() {
        }

        public Lista(String nome) {
            super();
            this.nome = nome;

        }

        public String getNome() {
            return nome;
        }

        public void setNome(String nome) {
            this.nome = nome;
        }

          @Override
        public String toString() {
            return nome;
        }
    }

My code 'list Adapter'

    package com.example.app;

import java.util.List;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

public class Listaadapter extends ArrayAdapter<Lista> {

        private Context context;
        private List<Lista> lista = null;

        public Listaadapter(Context context,  List<Lista> lista) {
            super(context,0, lista);
            this.lista = lista;
            this.context = context;
        }

        @Override
        public View getView(int position, View view, ViewGroup parent) {
            Lista tabela = lista.get(position);

            if(view == null)
                view = LayoutInflater.from(context).inflate(R.layout.lista, null);


            TextView textViewNomeLista = (TextView) view.findViewById(R.id.text);
            textViewNomeLista.setText(tabela.getNome());


            return view;
        }
    }

Answer 1

As I suggested earlier, the idea is to create a class that inherits from ActionBarActivity but which has the support methods of the class ListActivity.

The class would be this:

public class ListActionBarActivity extends ActionBarActivity {

    /**
     * This field should be made private, so it is hidden from the SDK.
     * {@hide}
     */
    protected ListAdapter mAdapter;
    /**
     * This field should be made private, so it is hidden from the SDK.
     * {@hide}
     */
    protected ListView mList;

    private Handler mHandler = new Handler();

    private Runnable mRequestFocus = new Runnable() {
            public void run() {
                    mList.focusableViewAvailable(mList);
            }
    };

    /**
     * This method will be called when an item in the list is selected.
     * Subclasses should override. Subclasses can call
     * getListView().getItemAtPosition(position) if they need to access the
     * data associated with the selected item.
     *
     * @param l The ListView where the click happened
     * @param v The view that was clicked within the ListView
     * @param position The position of the view in the list
     * @param id The row id of the item that was clicked
     */
    protected void onListItemClick(ListView l, View v, int position, long id) {
    }

    /**
     * Ensures the list view has been created before Activity restores all
     * of the view states.
     *
     *@see android.app.Activity#onRestoreInstanceState(android.os.Bundle)
     */
    @Override
    protected void onRestoreInstanceState(Bundle state) {
            ensureList();
            super.onRestoreInstanceState(state);
    }

    /**
     * @see android.app.Activity#onDestroy()
     */
    @Override
    protected void onDestroy() {
            mHandler.removeCallbacks(mRequestFocus);
            super.onDestroy();
    }

    /**
     * Provide the cursor for the list view.
     */
    public void setListAdapter(ListAdapter adapter) {
            synchronized (this) {
                    ensureList();
                    mAdapter = adapter;
                    mList.setAdapter(adapter);
            }
    }

    /**
     * Set the currently selected list item to the specified
     * position with the adapter's data
     *
     * @param position
     */
    public void setSelection(int position) {
            mList.setSelection(position);
    }

    /**
     * Get the position of the currently selected list item.
     */
    public int getSelectedItemPosition() {
            return mList.getSelectedItemPosition();
    }

    /**
     * Get the cursor row ID of the currently selected list item.
     */
    public long getSelectedItemId() {
            return mList.getSelectedItemId();
    }

    /**
     * Get the activity's list view widget.
     */
    public ListView getListView() {
            ensureList();
            return mList;
    }

    /**
     * Get the ListAdapter associated with this activity's ListView.
     */
    public ListAdapter getListAdapter() {
            return mAdapter;
    }

    private void ensureList() {
            if (mList != null) {
                    return;
            }
            setContentView(com.android.internal.R.layout.list_content_simple);

    }

    private AdapterView.OnItemClickListener mOnClickListener = new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v, int position, long id)
            {
                    onListItemClick((ListView)parent, v, position, id);
            }
    };

}

The maximum code that the ListActivity provides, but only one method is left out. Because the ActionBarActivity writes about the method onContentChanged of adds the modifier final, so it is not possible to write it in the created class.

But by its use, the ListActionBarActivity must meet.
