我有ActionBarDrawerToggle问题

Question

Recently I was using in my App this feature. But, using the ActionBarDrawerToggle a new app, I went unused error in that function. So I implemented import android.support.v7.app.ActionBarDrawerToggle; But now the code does not work for me.

public class MainActivity extends ActionBarActivity {
private ListView drawerList;
private String[] drawerOptions;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle drawerToggle;
private Fragment[] fragments = new Fragment[]{
                                               new MainFragment(),
                                               new AcordesFragment(),
                                               new AfinadorFragment(),
                                               new AboutFragment(),
                                               new ExitFragment(),
};

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

    drawerList = (ListView) findViewById(R.id.leftDrawer);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    drawerOptions = getResources().getStringArray(R.array.drawer_options);

    drawerList.setAdapter(new ArrayAdapter<String> (this,
                                                    R.layout.drawer_list_item,
                                                    drawerOptions));

    drawerList.setItemChecked(0, true);
    drawerList.setOnItemClickListener(new DrawerItemClickListener());

    drawerToggle = new ActionBarDrawerToggle(this,
                                            drawerLayout,
                                            R.drawable.ic_drawer,
                                            R.string.drawer_open,
                                            R.string.drawer_close){
                                                                    public void onDrawerClosed(View view){
                                                                        ActivityCompat.invalidateOptionsMenu(MainActivity.this);
                                                                    }
                                                                    public void onDrawerOpened(View drawerView){
                                                                        ActivityCompat.invalidateOptionsMenu(MainActivity.this);
                                                                    }
                                             };

    drawerLayout.setDrawerListener(drawerToggle);

    FragmentManager manager = getSupportFragmentManager();
    manager.beginTransaction()
            .add(R.id.contentFrame, fragments[0])
            .add(R.id.contentFrame, fragments[1])
            .add(R.id.contentFrame, fragments[2])
            .add(R.id.contentFrame, fragments[3])
            .add(R.id.contentFrame, fragments[4])
            .hide(fragments[1])
            .hide(fragments[2])
            .hide(fragments[3])
            .hide(fragments[4])
            .commit();

    ActionBar actionbar = getSupportActionBar();
    actionbar.setDisplayHomeAsUpEnabled(true);
    actionbar.setHomeButtonEnabled(true);

    if( getIntent().getBooleanExtra("Exit me", false)){
        finish();
        return; // add this to prevent from doing unnecessary stuffs
    }

}

The error is in the following code:

    drawerList.setOnItemClickListener(new DrawerItemClickListener());

    drawerToggle = new ActionBarDrawerToggle(this,
                                            drawerLayout,
                                            R.drawable.ic_drawer,
                                            R.string.drawer_open,
                                            R.string.drawer_close){
                                                                    public void onDrawerClosed(View view){
                                                                        ActivityCompat.invalidateOptionsMenu(MainActivity.this);
                                                                    }
                                                                    public void onDrawerOpened(View drawerView){
                                                                        ActivityCompat.invalidateOptionsMenu(MainActivity.this);
                                                                    }
                                             };

Surely Be That it has changed the syntax When using the ActionBarDrawerToggle but can not find.

Thank you very much for everything

Thank you very much for everything. The error has been resolved. Thank you very much to @hata and @Spring Breaker

Here is the corrected code so that other people can see it

public class MainActivity extends ActionBarActivity {
private ListView drawerList;
private String[] drawerOptions;
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle drawerToggle;
private Fragment[] fragments = new Fragment[]{
                                               new MainFragment(),
                                               new AcordesFragment(),
                                               new AfinadorFragment(),
                                               new AboutFragment(),
                                               new ExitFragment(),
};


private class DrawerItemClickListener implements ListView.OnItemClickListener {

    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

    }
};

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

    drawerList = (ListView) findViewById(R.id.leftDrawer);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    drawerOptions = getResources().getStringArray(R.array.drawer_options);

    drawerList.setAdapter(new ArrayAdapter<String> (this,
                                                    R.layout.drawer_list_item,
                                                    drawerOptions));

    drawerList.setItemChecked(0, true);

    drawerList.setOnItemClickListener(new DrawerItemClickListener());

    drawerToggle = new ActionBarDrawerToggle(this,
                                            drawerLayout,
                                            //R.drawable.ic_drawer,
                                            R.string.drawer_open,
                                            R.string.drawer_close){
                                                                    public void onDrawerClosed(View view){
                                                                        ActivityCompat.invalidateOptionsMenu(MainActivity.this);
                                                                    }
                                                                    public void onDrawerOpened(View drawerView){
                                                                        ActivityCompat.invalidateOptionsMenu(MainActivity.this);
                                                                    }
                                             };

    drawerLayout.setDrawerListener(drawerToggle);
