I want to disable the navigation drawer button animation using this answer, but I can't override the onDrawerSlide cause it is not showing in the auto-completion list.

As a newbie here and in Android app development, how can I include it? What am I missing here?

setSupportActionBar(toolbar);

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.main);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_open, R.string.navigation_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
}
...
}
To Access the OnDrawerSlide method , you have to override the method which is implimented in ActionBarDrawerToggle class, example is shown below
drawerToggle = new ActionBarDrawerToggle(this, drawerLayout,
getToolbar(), R.string.open, R.string.close) {
#Override
public void onDrawerSlide(View drawerView, float slideOffset) {
super.onDrawerSlide(drawerView, slideOffset);
}
};

As suggested in many have put the navigationView in the last of the xml also. still does not help. Made many changes. as suggested in many have put the navigationView in the last of the xml also. still does not help.

Adding to the above.I have called setContentView() in onCreate() as well as onResume() .I removed the latter. and it worked fine.
I'm working on a drawer layout. I want to replace the main activity screen with a fragment when I click a menu item, but it doesn't show a toolbar when I set the background of a fragment on some color app. Work done so far ...

You are using relative layout so you have to position every single child in relative layout since you are not doing it. framelayout overlapping the toolbar when there is not color in framelayout toolbar visible to you and it does not go anywhere so whenever you add a color toolbar becomes invisible to you but not from screen it will be under the framelayout...
so add below line in framelayout
android:layout_below="#id/toolbar"
I have a problem.
I create a DrawerLayout and I use it as my MainLayout.
For my menu, I create a nav_header with two TextView.
Of course, when I try to modify the TextView, I got a null object reference, because the TextView are from another layout.
How can I setText for the TextView from another layout (specifically nav_header)?
I tried LayoutInflate but the problem doesn't disappear (probably i set things bad).
Can anyone help me?
MainActivity.java:
public class MainActivity extends AppCompatActivity{
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mToggle;
private NavigationView navigationView;
private TextView logout_txt, name_txt;
private PermissionManager permissionManager;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final LayoutInflater layoutInflater = getLayoutInflater();
final View view = layoutInflater.inflate(R.layout.nav_header, null);
Log.d("USERNAME: ", ParseUser.getCurrentUser().getUsername());
name_txt = view.findViewById(R.id.txt_username_view);
name_txt.setText(ParseUser.getCurrentUser().getUsername());
ParseInstallation.getCurrentInstallation().saveInBackground();
init();
setUpDrawerContent(navigationView);
}
private void init() {
mDrawerLayout = findViewById(R.id.drawer_layout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
navigationView = findViewById(R.id.nav_view);
logout_txt = findViewById(R.id.logout);
permissionManager = new PermissionManager() {};
permissionManager.checkAndRequestPermissions(this);
name_txt.setText(ParseUser.getCurrentUser().getUsername());
}

<?xml version="1.0" encoding="utf-8"?>

UPDATE:
I tried this code, and the applications starts, but the setText doesn't set text.
You are using a wrong method to use the drawerlayout. You could simply use the Navigation Drawer Activity in Android Studio for creating a navigation drawer. Navigation Drawer Layout automatically creates 4 layout files and a Java file for this purpose. I'm adding them right bellow-
MainActivity.java
package com.example.user.myapplication;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = findViewById(R.id.drawer_layout);

drawer.closeDrawer(GravityCompat.START);
} else {

}
}

When I add a Button or TextView it crashes. Actually I am new to android programming. I have searched a lot and found that the content of nav drawer activity should be put in content_** folder. In the same way I put a text view in content_main2.xml and it crashes. I put it in the FrameLayout and this time it also crashes.please help me out.

And finally I decided not to use fragments then I saw a tutorial NAV DRAWER on every activity without fragment.I created a new nav activity named test and put a TextView in it.it is working but When I add a button it crashes.

start coding in FirstFragment's layout because you are replacing content_main2.xml to FirstFragment's layout.
May be it will help you.
You can edit like this app_bar.main2.xml

I am working with Navigation Drawer in Android.I have code from some examples.In my code working to change the drawer open and drawer close title but the panel is not open.I not insert the ListView array. My main Problem is not open the panel.Is anything I missed in the code?

DrawerLayout expects it's first child to be the actual layout and the second one to be the drawer. So, to make it work you should change your layout to (assuming that your entire drawer consists of only one ListView):
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:layout_height="150dp"
android:layout_width="match_parent"
android:id="#+id/toolbar"
android:background="?attr/colorPrimary"
android:minHeight="?android:attr/actionBarSize"/>
</LinearLayout>
<ListView
android:id="#+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:background="#000000"
android:layout_gravity="start"/>
</android.support.v4.widget.DrawerLayout>
It looks like your xml layout needs to be re-arranged. The DrawerLayout should wrap two items; 1) a View or ViewGroup to set as the page content (e.g., RelativeLayout containing a Toolbar and Fragment container); 2) a View or ViewGroup that holds your NavigationDrawer items (e.g., ListView).
<android.support.v4.widget.DrawerLayout
android:id="#+id/navigation_drawer_layout"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/your_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:background="#color/your_toolbar_color"
android:minHeight="?attr/actionBarSize"/>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#+id/your_toolbar"/>
</RelativeLayout>
<ListView
android:id="#+id/your_drawer_list"
android:layout_width="#dimen/drawer_width"
android:layout_height="match_parent"
android:layout_gravity="left"
android:background="#color/your_drawer_color"
android:divider="#null"/>
</android.support.v4.widget.DrawerLayout>
You can get a more detailed explanation and examples here:
https://developer.android.com/training/implementing-navigation/nav-drawer.html
If your list is empty and you have the height as wrap_content, the height will be 0. Changing it to match_parent will have it fill the screen regardless of the content.
<ListView
android:id="#+id/drawer_list"
android:layout_width="240dp"
android:layout_height="match_parent"
android:background="#000000"
android:layout_gravity="start"/>
