Code

mTitle = mDrawerTitle = getTitle();
mNavigationDrawerItemTitles = getResources().getStringArray(R.array.navigation_drawer_items_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);

setupToolbar();

DataModel[] drawerItem = new DataModel[1];

drawerItem[0] = new DataModel(R.drawable.connect, "exit");

getSupportActionBar().setHomeButtonEnabled(true);

DrawerItemCustomAdapter adapter = new DrawerItemCustomAdapter(this, R.layout.list_view_item_row, drawerItem);
mDrawerList.setAdapter(adapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerLayout.setDrawerListener(mDrawerToggle);
setupDrawerToggle();

And

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) {

    Fragment fragment = null;

    switch (position) {
        case 0:
            fragment = new ConnectFragment();
            break;
        case 1:
            fragment = new FixturesFragment();
            break;
        case 2:
            //fragment = new TableFragment();
            session.clear();
            Intent i = new Intent(Products.this, MainActivity.class);
            startActivity(i);
            finish();
            break;

        default:
            break;
    }

    if (fragment != null) {
        FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();

        mDrawerList.setItemChecked(position, true);
        mDrawerList.setSelection(position);
        setTitle(mNavigationDrawerItemTitles[position]);
        mDrawerLayout.closeDrawer(mDrawerList);

    } else {
        Log.e("MainActivity", "Error in creating fragment");
    }
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {

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

    return super.onOptionsItemSelected(item);
}

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

}

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

void setupToolbar() {
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
    getSupportActionBar().setDisplayShowHomeEnabled(true);
    getSupportActionBar().setDisplayShowTitleEnabled(false);
}

void setupDrawerToggle() {
    mDrawerToggle = new android.support.v7.app.ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.empty, R.string.empty);
    //This is necessary to change the icon of the Drawer Toggle upon state change.
    mDrawerToggle.syncState();
}
