This question might have been asked many times, but none of the solutions are working for me.
I have an activity that implements navigation drawer but the drawer toggle button is not working.
I don't know what I am missing, but it is really bothering me.

Edit
It seems that the buttons on action bar are not working altogether. Even the overflow button does not responds to clicks
I did followings:
#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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
} else {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
drawer.openDrawer(GravityCompat.START);
}
}
return super.onOptionsItemSelected(item);
}
and it works OK.
R.id.driver_layout - is my Layout in XML.

I'm trying to add fragments to a navigation drawer.
But I have the error: can not resolve the 'fragment' symbol ...
I added: import android.support.v4.app.Fragment;
And checked on Grandle for compile 'com.android.support:appcompat-v7:25.3.1'
Where is the mistake?

You are trying to assign a Fragment Object to an non-defined property.
You should declare a Fragment Object as a the top property, so it could be accessible to all methods for you transactions.

This is what I currently have:
I have tried spinner inside layout in my code, but it's not producing what I want. Please give me some help. I need it to look more like the following:
I'm trying to combine a navigation view and page viewer. I've got that working fine, the problem I'm having is adding the drawer toggle to the action bar (or tool bar) in order to bring up the navigation drawer. I don't care if I can add the toggle to the default view pager or by implementing my own bar (you can see the commented out sections). I actually had both bars on screen at one time...this was not what I wanted. I'm just experimenting to see what's possible. Any help would be appreciated, and thanks in advance.

I actually solved the issue with the following changes:
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_kiosk_pager);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout_kiosk);
actionBarDrawerToggle = new ActionBarDrawerToggle(
this, drawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
navigationView = (NavigationView)findViewById(R.id.nav_view_kiosk);
navigationView.setNavigationItemSelectedListener(this);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
But now the toggle doesn't pull out the drawer and the drawer appears behind the action bar.... Help.
Hello i am new to android. I would like to implement navigation drawer consisting of a list of items, which when clicked opens a new activity. Basically a navigation drawer across all the activities. When I select an item from the navigation drawer that particular activity opens but the icon for the navigation drawer (hamburger icon) disappears. How do I get that?

It is advised to use Navigation Drawer with fragments as it will maintain the nav drawer. You have to convert your activities in fragments. Please check developer link- http://developer.android.com/training/implementing-navigation/nav-drawer.html
Has anyone figured out how to get this method of one main activity pushing in fragments to work with the back button ?
Everything works fine going "forward", and all the fragments get pulled into the content frame, but as soon as you hit the back button, the application closes...most likely because it is the only activity running and the back button closes the activity.
Anyway to put code in to get the fragment manager to go back to the last fragment and not close the activity on the back button ?
The case is the following: I have two types of users, type1 and type2. Both have to login in order to go to the main activity which has a Navigation Drawer. The items in the navigation drawer depends on the type of the user. How can I change the items of the navigation drawer at runtime after I know the user type.

I found easier way to change navigation view ( work with both submenu and menu). You can re-inflate NavigationViewat runtime with 2 lines of code. In this example i re-inflate with new_navigation_drawer_items.xml when user successfully logged-in
navigationView.getMenu().clear(); //clear old inflated items.
navigationView.inflateMenu(R.menu.logged_in_navigation_drawer_items); //inflate new items.
When user log out just re-inflate again with logged_out_navigation_drawer_items.xml
navigationView.getMenu().clear(); //clear old inflated items.
navigationView.inflateMenu(R.menu.logged_out_navigation_drawer_items); //inflate new items.
