Hi ich will Fragments und action bar in meinem Projekt für android 2.2-so hatte ich Hinzugefügt-Support-Bibliothek - v4 und v7, aber immer noch ich bin immer Fehler wie

Fragment kann nicht aufgelöst werden, um einen Typ und Die Methode getActionBar() ist nicht definiert für den Typ MainActivity.

hier ist mein code:

    mPlanetTitles = getResources().getStringArray(R.array.planets_array);
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.left_drawer);

    //set a custom shadow that overlays the main content when the drawer

            invalidateOptionsMenu(); //creates call to
                                        //onPrepareOptionsMenu()
        }

        public void onDrawerOpened(View drawerView) {

    if (savedInstanceState == null) {
        selectItem(0);
    }
}

@Override

    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.main, menu);
    return super.onCreateOptionsMenu(menu);

/* Called whenever we call invalidateOptionsMenu() */

     //The action bar home/up action should open or close the drawer.
     //ActionBarDrawerToggle will take care of this.
    if (mDrawerToggle.onOptionsItemSelected(item)) {

        //catch event that there's no activity to handle intent
        if (intent.resolveActivity(getPackageManager()) != null) {
            startActivity(intent);
        } else {
            Toast.makeText(this, R.string.app_not_available, Toast.LENGTH_LONG).show();
        }
        return true;
    default:
        return super.onOptionsItemSelected(item);
    }
}

/* The click listner for ListView in the navigation drawer */
private class DrawerItemClickListener implements
        ListView.OnItemClickListener {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            long id) {
        selectItem(position);
    }
}

private void selectItem(int position) {
    //update the main content by replacing fragments
    Fragment fragment = new PlanetFragment();
    Bundle args = new Bundle();
    args.putInt(PlanetFragment.ARG_PLANET_NUMBER, position);
    fragment.setArguments(args);

    FragmentManager fragmentManager = getFragmentManager();
    fragmentManager.beginTransaction()
            .replace(R.id.content_frame, fragment).commit();

    //update selected item and title, then close the drawer
    mDrawerList.setItemChecked(position, true);
    setTitle(mPlanetTitles[position]);
    mDrawerLayout.closeDrawer(mDrawerList);
}

@Override
public void setTitle(CharSequence title) {
    mTitle = title;
    getSupportActionbar().setTitle(mTitle);
}

/**

 * onPostCreate() and onConfigurationChanged()...
 */

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    //Sync the toggle state after onRestoreInstanceState has occurred.
    mDrawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    //Pass any configuration change to the drawer toggls
    mDrawerToggle.onConfigurationChanged(newConfig);
}

/**
 * Fragment that appears in the "content_frame", shows a planet
 */
public static class PlanetFragment extends Fragment {
    public static final String ARG_PLANET_NUMBER = "planet_number";

    public PlanetFragment() {
        //Empty constructor required for fragment subclasses
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.fragment_planet,
                container, false);
        int i = getArguments().getInt(ARG_PLANET_NUMBER);
        String planet = getResources()
                .getStringArray(R.array.planets_array)[i];

        int imageId = getResources().getIdentifier(
                planet.toLowerCase(Locale.getDefault()), "drawable",
                getActivity().getPackageName());
        ((ImageView) rootView.findViewById(R.id.image))
                .setImageResource(imageId);
        getActivity().setTitle(planet);
        return rootView;
    }
}
}

Nun hier hatte ich versucht, sowohl die

getSupportActionbar() und und getActionBar(). Aber beide Fehler gibt.

Auch ich habe activity_main.xml Datei, sondern in setContentView(R.layout.activity_main); auch gibt es Fehler, wie activity_main kann nicht aufgelöst werden oder ist nicht ein Feld`

Hatte ich bereits setup-compact library-Datei im folgenden Screenshot
