PreferenceActivity with Navigation Drawer Throws Null Pointer Exception - android

I had a PreferenceActivity which was working fine. Then, I decided to add a navigation drawer to it, and edited the layouts according to my other activity layouts which also have working navigation drawers. However, after doing that, my PreferenceActivity stopped opening and started throwing a NPE on start. I can't even open that activity anymore. Problem is in onCreate, obviously, and also in an onClick method as stated in the logcat. Yet, there are two onClick's in this activities onCreate, and I'm not seeing how those result in a NPE, since they are the exact same in my other working activities. My layout xmls are seperated into 3 xmls according to the default DrawerLayout implementation. Without further due, here are the codes and xmls:
PreferenceActivity:
public class FirstYearCoursesActivity extends PreferenceActivity
implements NavigationView.OnNavigationItemSelectedListener {
private AppCompatDelegate mDelegate;
Toolbar toolbar;
#Override

getDelegate().installViewFactory();

window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);

DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view2);
navigationView.setNavigationItemSelectedListener(this);

EDIT:
One thing worth mentioning is that I triple checked the activity and it's adapter that leads to this PreferenceActivity on list item click. I reversed all my Drawer Layout implementations, and I was able to open this PreferenceActivity through parent activity. Navigation Drawer code, or layouts are the ones messing with it. I'm getting the listview.onclick(adapter) NPE because my list item click on parent activity goes to a null reference, which in this case it the PreferenceActivity itself. Also debug didn't show me anything null in PreferenceActivity's onCreate, except savedInstanceState.

I was able to reproduce the same NPE using your code and fixed it by replacing the addPreferencesFromResource call (note that it's deprecated) using a fragment instead as described in these threads:
Android: Preference Fragment with a Navigation Drawer's Fragment
What to use instead of "addPreferencesFromResource" in a PreferenceActivity?
Although, on my version, the preferences view overlaps the toolbar and I am not sure what the activity layout should be to fix that, maybe it will be OK in yours.

Navigation drawer: How do I set the navigation item selected listener with custom tool bar?

I don't see any error when I open the navigation drawer, but it keeps getting closed whenever I select an item. Edit: My drawer gets closed automatically on item selection without showing the Toast message as mentioned in NavigationItemSelectedListener. The toast message is not displayed.
I have used a custom toolbar in which I have added an image view as a side menu button.

I have tried other method with default toolbar, and it was working properly but I am not able to figur out the problem with custom toolbar. I wanted to display a toast on item selection inside the navigation drawer. Please help me find the solution...
Thank you.
In onNavigationItemSelected, Change this
return false;
to
return true;
After so long finally I found the solution to my problem. But I don't know why it was happening like that but I'm happy that it is finally working. And I am also very happy to share it with those who may experience the same issue in the future which I hope they won't.
I referred to the link from the Git hub for this solution. Link: https://github.com/priyalbhatewara123/Navigation-Drawer--Android
Finally here is the solution I found,
I just added the following lines of codes below </ScrollView> which was above <ScrollView> in the problematic code used in my activity_custom_toolbar.xml.
<com.google.android.material.navigation.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:headerLayout="#layout/header_file"
app:menu="#menu/main_manu"
android:layout_gravity="start"/>
I'm also adding the code after changes,

onNavigationItemSelected not being called [duplicate]

I am trying to use NavigationView from Android Support Design library in my app. For some reason, OnNavigationItemSelected listener is not being called. Here is my code
Activity Layout
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/drawer_header"
app:menu="#menu/drawer_menu" />
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.DrawerLayout>
Activity onCreate()
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutID());
toolbar = (Toolbar) findViewById(R.id.activity_toolbar);
setSupportActionBar(toolbar);
toolbar.inflateMenu(R.menu.common_menu);
final ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setHomeAsUpIndicator(R.drawable.ic_menu_white_24dp);
actionBar.setDisplayHomeAsUpEnabled(true);
}
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
navigationView = (NavigationView) findViewById(R.id.navigation_view);
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(final MenuItem menuItem) {
Snackbar.make(contentLayout, menuItem.getTitle() + " pressed", Snackbar.LENGTH_LONG).show();
menuItem.setChecked(true);
// allow some time after closing the drawer before performing real navigation
// so the user can see what is happening
drawerLayout.closeDrawer(GravityCompat.START);
mDrawerActionHandler.postDelayed(new Runnable() {
#Override
public void run() {
navigate(menuItem.getItemId());
}
}, DRAWER_CLOSE_DELAY_MS);
drawerLayout.closeDrawers();
return true;
}
});
usernameTextView = (TextView) findViewById(R.id.drawer_header_username);
usernameTextView.setText(getAppDContext().getAccount().getUsername());
}
When you make XML layout, you should write down NavigationView after BaseLayout (FrameLayout, LinearLayout, etc..)
<DrawerLayout>
<FrameLayout />
<NavigationView />
</DrawerLayout>
For me this did the trick!
navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.bringToFront();
Your activity main layout should look like this:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/navigationDrawer"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/activity_main_content" />
<android.support.design.widget.NavigationView
android:id="#+id/navigationView"
style="#style/NavigationView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="right"
app:headerLayout="#layout/header"
app:menu="#menu/menu_drawer"/>
</android.support.v4.widget.DrawerLayout>
In this NavigationView I linked header.xml and menu_drawer.xml (from menu folder)
for example menu_drawer.xml :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="#+id/nav1"
android:checked="true"
android:icon="#drawable/logo"
android:title="Navigation item 1"/>
<item
android:id="#+id/nav2"
android:icon="#drawable/logo"
android:title="Navigation item 2"/>
</group>
</menu>
than your java code:
public class ActivityMain extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setUpToolbar();
setUpNavDrawer();
}
private void setUpNavDrawer() {
NavigationView view = (NavigationView) findViewById(R.id.navigationView);
mDrawerLayout = (DrawerLayout) findViewById(R.id.navigationDrawer);
view.setNavigationItemSelectedListener(this);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.drawerOpen, R.string.drawerClose);
mDrawerLayout.addDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
}
Check if this work for you. In my project works like a charm.

How to create an android drawer with custom icons on it?

Can anyone please help me on designing this android layout? I want to put two icons on the drawer toolbar like on the image below.
This is LeftNavigationActivity.class
public class LeftNavigationActivity extends BaseActivity
implements NavigationView.OnNavigationItemSelectedListener {
private ImageView profilePic;
Session session;
FragmentManager fragmentManager = getSupportFragmentManager();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_left_navigation);
this.setTitle("Home");
session = new Session(this);
if (!session.loggedIn()) {
logOut();
}
View v = getLayoutInflater().inflate(R.layout.nav_header_left_navigation,
null);
TextView username = (TextView) v.findViewById(R.id.username);
Intent intent = getIntent();
String uname = intent.getStringExtra("username");
Toast.makeText(this, "Welcome " + uname, Toast.LENGTH_SHORT).show();
username.setText(uname);
LoansAndDebtsFragment loansAndDebtsFragment = new LoansAndDebtsFragment();
fragmentManager.beginTransaction().replace(R.id.layout_for_fragment,
loansAndDebtsFragment, loansAndDebtsFragment.getTag()).commit();
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) 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 = (NavigationView)
findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
FragmentManager fragmentManager = this.getSupportFragmentManager();
int stackCount = fragmentManager.getBackStackEntryCount();
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else if (fragmentManager.getFragments() != null) {
LoansAndDebtsFragment loansAndDebtsFragment = new
LoansAndDebtsFragment();
fragmentManager.beginTransaction().replace(R.id.layout_for_fragment,
loansAndDebtsFragment, loansAndDebtsFragment.getTag()).commit();
}
}
The LeftNavigationActivity is the BaseDrawerActivity which contains the navigation menu.

Open Android Studio
Start a new Android Studio project
Select Navigation Drawer Activity
Pick your icons here: https://material.io/icons/
1. Create an menu XML with your desired menu items and put this XML into res/menu/ folder.
menu.xml:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.ferdous.advancefilter.MainActivity">
<item
android:id="#+id/action_notification"
android:title="Notification"
android:icon="#drawable/ic_action_notification"
app:showAsAction="always" />
<item
android:id="#+id/action_warning"
android:title="Notification"
android:icon="#drawable/ic_action_warning"
app:showAsAction="always" />
</menu>
2. In your Activity, override method onCreateOptionsMenu() to add menu items to Toolbar and override method onOptionsItemSelected() to handle the Toolbar item click event.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#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();
switch (id) {
case R.id.action_notification:
// Do something
break;
case R.id.action_warning:
// Do something
break;
}
return super.onOptionsItemSelected(item);
}
OUTPUT:
#. If you want to add count badge over your menu item like below then you can follow my another answer Notification Badge On Action Item Android. I have added detail steps and codes.
Hope this will help~

Clicking hamburger icon on Toolbar does not open Navigation Drawer

I have a simple android.support.v7.widget.Toolbar and all I am trying to do is to open a NavigationDrawer by pressing the "hamburger" icon in the top left corner. The "hamburger" button is visible, and when I start to pull from the left I see the animation on the button but pressing the button does not open/close the NavigationDrawer as I expect. I have followed the [Google Documentation][1] and still am not able to figure this out. Sorry for any confusion, below is the simplified code I am currently attempting to use:
public class MainActivity extends AppCompatActivity implements
View.OnClickListener,
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Log.d("NICK", "button button button..................");
}
});
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer);
NavigationView n = (NavigationView) findViewById(R.id.nav);
mDrawerLayout.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Log.d("NICK", "button button button..................");
}
});
//mDrawerLayout.setDrawerListener(mDrawerToggle);
n.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(MenuItem menuItem) {
switch (menuItem.getItemId()) {
////.......
}
mDrawerLayout.closeDrawers(); // CLOSE DRAWER
return true;
}
});
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Log.d("NICK","CWECNEWKVNERIPNVIEWNFVIPEWNVIPEWNVPIEWNVPIEWNVPIEWNVPIRWNVPRWVPO");
switch (item.getItemId()) {
case android.R.id.home:
mDrawerLayout.openDrawer(GravityCompat.START); // OPEN DRAWER
Log.d("NICK","CWECNEWKVNERIPNVIEWNFVIPEWNVIPEWNVPIEWNVPIEWNVPIEWNVPIRWNVPRWVPO");
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.drawer, menu);
return true;
}
}
}
And as it is I do not get any of the log debug statements when running.
This is essentially the issue I have: https://stackoverflow.com/a/26636045/1489990. I've followed this and it just doesn't work.
It is my understanding that setNavigationOnClickListener is called when the hamburger icon is pressed, and this is where I am focusing my efforts is to get the event handled properly because when I press the button I do not get my log statement. Let me know if this idea is incorrect. https://developer.android.com/reference/android/widget/Toolbar.html#setNavigationOnClickListener(android.view.View.OnClickListener)

In your ActivityMain.xml, the toolbar is outside of the DrawerLayout. That's the problem. If you want Toolbar to interact with DrawLayout, Toolbar needs to be a child of DrawerLayout.
To fix the problem, make DrawerLayout the root of your activity. Here's the documentation. The relevant quote is:
To add a navigation drawer, declare your user interface with a
DrawerLayout object as the root view of your layout. Inside the
DrawerLayout, add one view that contains the main content for the
screen (your primary layout when the drawer is hidden) and another
view that contains the contents of the navigation drawer.
So basically, structure your ActivityMain.xml to be something like this:
<android.support.v4.widget.DrawerLayout ...>
<RelativeLayout ...>
<android.support.v7.widget.Toolbar .../>
<!-- Your other content goes here -->
</RelativeLayout>
<android.support.design.widget.NavigationView .../>
</android.support.v4.widget.DrawerLayout>
That should take care of the problem.
Override onOptionsItemSelected method and use below
if(item.getItemId() == android.R.id.home){ // use android.R.id
mDrawerLayout.openDrawer(Gravity.LEFT);
}
You need to sync the drawer toggle:
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
EDIT: That code is working for me (copied from your post)
public class TempActivity extends AppCompatActivity {
private ActionBarDrawerToggle mDrawerToggle;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.temp);
setupDrawer();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
#Override
public boolean onOptionsItemSelected(final MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
private void setupDrawer() {
Toolbar toolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.my_drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,toolbar,R.string.drawer_open, R.string.drawer_close) {
public void onDrawerClosed(View view) {
super.onDrawerClosed(view);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
}
};
mDrawerLayout.setDrawerListener(mDrawerToggle);
}
}

But if you are using the new NavigationView, then you don't need the toggle etc. Here is a good example how to use it.
I fixed it by giving openable which is drawerLayout to navigateUp function.
More info navigateUp Doc
override fun onSupportNavigateUp(): Boolean {
val navController = this.findNavController(R.id.host_fragment)
return NavigationUI.navigateUp(navController,drawer_layout)
}
If it helps somebody, to me it happened the same because of the stupid error of calling setSupportActionBar(toolbar) two times. Just call it once in onCreate method and never again. My mistake was I called it later in another method.
Use ActionBarDrawerToggle and implement public boolean onOptionsItemSelected(MenuItem item)
Toolbar DOES NOT have to be within a DrawerLayout, it's not likely to be the cause of this issue. toggle.onOptionsItemSelected(item) looks for the ID of the item selected and if it is android.R.id.home then the drawer's visibility is toggled. Thus Toolbar, or any View that creates a Home MenuItem, can be placed anywhere in your layout.
Within your activity:
ActionBarDrawerToggle toggle;
private void setupDrawerToggleInActionBar() {
// assuming a Toolbar has been initialized in your onCreate
this.setSupportActionBar(toolbar);
// setup the action bar properties that give us a hamburger menu
ActionBar actionBar = this.getSupportActionBar();
if(actionBar != null) {
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
}
// the toggle allows for the simplest of open/close handling
toggle = new ActionBarDrawerToggle(this,
drawerLayout,
R.string.navigation_drawer_open,
R.string.navigation_drawer_close);
// drawerListener must be set before syncState is called
drawerLayout.setDrawerListener(toggle);
toggle.setDrawerIndicatorEnabled(true);
toggle.syncState();
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// This is required to make the drawer toggle work
if(toggle.onOptionsItemSelected(item)) {
return true;
}
/*
* if you have other menu items in your activity/toolbar
* handle them here and return true
*/
return super.onOptionsItemSelected(item);
}
Simply call function onOptionsItemSelected(MenuItem menuItem) of ActionBarDrawerToggle class on activity options menu managing function like below.
mDrawerToggle= new ActionBarDrawerToggle(activity, drawerLayout, R.string.nav_drawer_accessbility_drawer_open,
R.string.nav_drawer_accessbility_drawer_close);
#Override
public boolean onOptionsItemSelected(final android.view.MenuItem item) {
navigation().getOptionsMenuInflater(this).closeSearchView();
// The action bar home/up action should open or close the drawer.
// ActionBarDrawerToggle will take care of this behavior.
mDrawerToggle.onOptionsItemSelected(item);
return super.onOptionsItemSelected(item);
}
OR
override onOptionsItemSelected of activity like below
public boolean onOptionsItemSelected(MenuItem item) {
if (item != null && item.getItemId() == android.R.id.home) {
toggle();
}
return super.onOptionsItemSelected(item);
}
private void toggle() {
if (mDrawerLayout.isDrawerVisible(GravityCompat.START)) {
mDrawerLayout.closeDrawer(GravityCompat.START);
} else {
mDrawerLayout.openDrawer(GravityCompat.START);
}
}
For the drawer toggle you need to set "display home as up" to false:
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
As i have no specific answer to your problem, i want to suggest a completely different approach:
In my projects im using the Material Drawer developed by Mike Penz.
Its looks really nice, is easy to implement, and there is not much you have to worry about.
So if you cant find a solution for your problem, you could give it a try.
While accepted answer here works alright however, as they say "Prevention is better than cure".. Adding mDrawerToggle.syncState(); in onPostCreate and onConfigurationChanged() wroks much better as answerd by #mbmc above:
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
After a lot of different problems I found a way to make it work putting Toolbar Widget inside AppBarLayout.
Be sure that there is no other layout on top of widget toolbar!

Idk why...but changing return value to false rather than true fixed the ham Icon for me. on onOptionItemSelected override method
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
if(item.getItemId() == R.id.logout){
ParseUser.logOut();
Intent intent = new Intent(getApplicationContext(), MainActivity.class);
startActivity(intent);
Toast.makeText(this, "Logout Successful!", Toast.LENGTH_SHORT).show();
} else if(item.getItemId() == R.id.action_settings){
Toast.makeText(this, "No setting to update! Will be available later...", Toast.LENGTH_SHORT).show();
}
return true; // here change this to false
}
If none of the above answer works, please cross check again,
First you need to call setSupportActionBar(toolbar); and then do the necessary work for nav drawer. I wasted my 2 hours because of this silly mistake.
I had the same problem. However, it did not occur on all fragments. It occurred on one particular fragment.
Firstly, please follow #hungryghost 's answer mentioned above. Then do the following.
Adding the following piece of code helped the drawer open on click of the hamburger icon. It worked flawlessly for me. Thank you very much. :) My sincere apologies if this isn't the right way.
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
int itemId = item.getItemId();
if(itemId == android.R.id.home){
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
return super.onOptionsItemSelected(item);
}
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
I have found a simple solution to this problem is to call the setSupportActionBar(toolbar) method before the navigation drawer functions.

Navigation drawer: text is hidden below actionbar?

I added navigation drawer to my application. Everything works fine, but now I am trying to add a simple textView to menu, and am not succeeding. The problem is the fact that text is hidden underneath actionBar itself. Even 50dp margin from top isn't enough.
Do you have any tips on how to fix this issue?

You want to assign fitsSystemWindows and clipToPadding to the Navigation Drawer fragment (most probably the ListView)
Something like this -
<ListView 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"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:background="#cccc"
android:fitsSystemWindows="true"
android:clipToPadding="false"
/>
But in your case, you are using the FrameLayout on the activity_main itself to populate the Drawer contents. So you have to apply these two properties to the FrameLayout
<FrameLayout
android:id="#+id/left_drawer"
android:layout_width="200dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"
android:fitsSystemWindows="true"
android:clipToPadding="false"
android:background="#color/dark_brown">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Text"
android:textSize="40dp"
android:textColor="#ffffff"
android:id="#+id/textView"
android:gravity="center_vertical"/>
</FrameLayout>
Also, notice, you don't need following to your TextView anymore.
android:layout_marginTop="50dp"
android:layout_marginLeft="20dp"
