Navigation Drawer mit ActionBarDrawerToggle aufrufen/anzeigen

Hallo,

Ich bin neu hier im Forum und bin ebenfalls neu in der Android App Development World.

Ich habe folgendes Problem, bei dem ich eure Hilfe benötige:
Ich habe ein Navigation Drawer erstellt. Dieser kann durch das wischen vom linken Rand des Screens eingeblendet werden.
Ich habe nach einen Tutorial in der Toolbar eine ActtionBar mit einem DrawerToggle erstellt.

Laut dem Tutorial, müsste der N.D. beim drücken des D.T. eingeblendet werden, aber es geschiet nichts.

Wie kann ich es einrichten, dass beim betätigen des D.T. (Oben links in der Ecke) der N.T. eingeblendet wird?

Danke im Voraus!

Hier Zwei Screenshots:

Und hier die Codes:

Okay danke.

Ich habe den Code jetzt mal etwas umgeschrieben. Nur leider passiert immer noch nichts beim betätigen des Toggles.
Habe ich etwas vergessen? Was mache ich falsch?

Hier mein jetziger Code:

package [...].app1;

import android.content.Context;
import android.content.DialogInterface;
import android.content.res.Configuration;
import android.net.Uri;
import android.support.design.widget.NavigationView;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;

import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AlertDialog;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

import com.google.android.gms.appindexing.Action;
import com.google.android.gms.appindexing.AppIndex;
import com.google.android.gms.common.api.GoogleApiClient;

public class MainActivity extends AppCompatActivity {

Toolbar toolbar;
DrawerLayout drawerLayoutgesamt;
ActionBarDrawerToggle drawerToggle;

private ListView drawerList;
private ArrayAdapter<String> mAdapter;

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

    toolbar = (Toolbar) findViewById(R.id.toolbar1);
    setSupportActionBar(toolbar);

    drawerLayoutgesamt = (DrawerLayout) findViewById(R.id.drawerLayoutGesamt);
    drawerToggle = new ActionBarDrawerToggle(MainActivity.this,drawerLayoutgesamt,R.string.drawer_open, R.string.drawer_close);
    drawerLayoutgesamt.setDrawerListener(drawerToggle);

    getSupportActionBar().setDisplayHomeAsUpEnabled(true);
    drawerToggle.syncState();
}

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

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.action_settings) {
        return true;
    }

    if (drawerToggle.onOptionsItemSelected(item)) {
        return true;
    }

    return super.onOptionsItemSelected(item);
}

@Override
protected void onPostCreate(Bundle savedInstanceState) {
    super.onPostCreate(savedInstanceState);
    drawerToggle.syncState();
}

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    drawerToggle.onConfigurationChanged(new Configuration());
}

private void addDrawerItems() {
    String[] osArray = {"Feature #1", "Feature #2", "Feature #3", "Feature #4", "Feature #5"};
    mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, osArray);
    drawerList.setAdapter(mAdapter);
}

}

Meinst du

 import android.support.v4.widget.DrawerLayout;

durch

 import android.support.v7.app.ActionBarDrawerToggle;

ersetzen?

Ich habe jetzt diese Imports drin:

import android.support.v7.widget.ActionBarOverlayLayout;
import android.support.v7.app.ActionBarDrawerToggle;

Sind diese Deklarationen richtig?

    ActionBarOverlayLayout drawerLayoutgesamt;
    ActionBarDrawerToggle drawerToggle;
