First of all, I know this question has been asked before, I've spent an hour looking through other solutions, mostly from - getActionBar() returns null , and none have worked so another pair of eyes might be able to do something.
NavigationDrawer class which other classes inherit from:
public class NavigationDrawer extends AppCompatActivity {
String[] mDrawerTitles;
DrawerLayout mDrawerLayout;
ListView mDrawerList;
ActionBarDrawerToggle mDrawerToggle;
String activityTitle;
#Override
protected void onCreate(Bundle savedInstanceState) {
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_drawer_layout);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
mDrawerTitles = getResources().getStringArray(R.array.drawer_array);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.left_drawer);
activityTitle = getTitle().toString();
getSupportActionBar().setDisplayHomeAsUpEnabled(true); //here is where the error is thrown
getSupportActionBar().setHomeButtonEnabled(true);
addDrawerItems();
navDrawerSetup();
}
MainActiviy which extends the above:
public class MainActivity extends NavigationDrawer {
int[]images={R.drawable.user_manual,R.drawable.tips_tricks, R.drawable.troubleshooting};
Integer printer;
ListView myListView;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View contentView = inflater.inflate(R.layout.activity_main, null, false);
mDrawerLayout.addView(contentView, 0);
}

In NavigationDrawer activity you are performing setContentView(R.layout.navigation_drawer_layout), and in navigation_drawer_layout there is no any Toolbar, which leads to an exception.
Doing the following in you NavigationDrawer.class
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); //This is null
setSupportActionBar(toolbar);
You are setting Activity toolbar to null, because there is no view in your R.layout.activity_main with R.id.toolbar ID. So when you try to set toolbar after the code above, you are trying to set a property in a null object, that produces a null pointer exception.
Remove the two lines above in your activity or declare a Toolbar view with R.id.toolbar ID on your R.layout.activity_main layout file. Doing that you will solve the problem.

public class MainActivity extends AppCompatActivity {
private DrawerLayout drawerLayout;
private ActionBarDrawerToggle actionBarDrawerToggle;
#Override

drawerLayout.addDrawerListener(actionBarDrawerToggle);

}
}
I want the navigation view to be only visible when the hamburger icon in the toolbar is clicked. Every tutorial I followed did the same things with me, however mine doesn't show inside the toolbar.
Pass toolbar instance during initiation of ActionBarDrawerToggle
actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout, toolbar, R.string.open,R.string.close);

My intention is to have an appbar with navigation drawer (icon on left), and options menu (icon on right). However, it appears to be stuck underneath the system default. Here is an image showing its preview:
Additionally, my styles.xml is:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar" parent="AppTheme">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
Changing AppCompat.Light.DarkActionBar to NoActionBar has no effect. The appbar with "AppName" just remains above the other appbar (which should show "BEEP" as text, in addition to the two icons for navbar and options menu) - NoActionBar is also defined in the manifest for the activity:
<activity
android:name=".MainActivity"
android:label="BEEP"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Here is the relevant part of the MainActivity.java, if needed:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
// Create the adapter that will return a fragment for each of the three
// primary sections of the activity.
mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());
// Set up the ViewPager with the sections adapter.
mViewPager = (ViewPager) findViewById(R.id.container);
mViewPager.setAdapter(mSectionsPagerAdapter);
TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));
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);
...
So, how can I get the toolbar (ID is "toolbar") to display instead of the default appbar that currently contains the text "AppName" in the above image? I also followed this, however there is no change in the result.
EDIT 1: The following screenshot shows my user-defined appbar appearing underneath the default, for some reason. I have also included my app_bar_appbar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

<android.support.v7.widget.Toolbar

app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_appbar" />
</android.support.design.widget.CoordinatorLayout>
As you are having Theme.AppCompat.Light.DarkActionBar to your Application tag of AndroidManifest all activity will include default actionbar.
Create one more theme in your styles.xml with NoActionBar and apply this to your NavigationDrawerActivity.
i.e.
<style name="navigation_theme" parent="Theme.AppCompat.Light.NoActionBar"/>
Set it to your Navigation Activity
<activity
android:name=".NavigationDrawerActivity"
android:label="#string/title_activity_navigation_drawer"
android:theme="#style/navigationtheme" />
Example of default theme with ActionBar and NavigationDrawerActivity with NoActionBar theme
EDIT
As #Talisman said, it was the issue with the TabLayout and ViewPager
of DrawerLayout
<?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:layout_height="wrap_content"

<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#android:color/holo_blue_light"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<!--Your content in this FrameLayout-->
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.and.NavigationDrawerActivity">
</FrameLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
app:srcCompat="#android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"

android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_navigation_drawer"
app:menu="#menu/activity_navigation_drawer_drawer" />
</android.support.v4.widget.DrawerLayout>
Now Set the TabLayout and ViewPager in other Fragment and Load that fragment in this FrameLayout on onCreate method of NavigationDrawerActivity
FragmentManager fm = getSupportFragmentManager();
FragmentTransaction tr = fm.beginTransaction();
tr.replace(R.id.frame_container, fragment);
tr.commitAllowingStateLoss();
where fragment is other fragment which contains your TabLayout and ViewPager.
Everything is looking perfect as it should be. If you just want to change the title of toolbar then you just have to add few lines of code in MainActivity.java
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// add few lines here like...
toolbar.setTitle("Your title here");
// ....
setSupportActionBar(toolbar);
If right option menu not showing then override these two method in MainActivity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return false;
}
return super.onOptionsItemSelected(item);
}
First of all select "AppTheme" from layout preview
Select Project Theme >> AppTheme.NoActionBar
To create option menu for your Activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()){
case R.id.menu_item:
//do need full stuff
break;
case R.id.menu_settings:
//do need full stuff
break;
}
}
create a menu.xml in res>menu folder
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/menu_item"
android:title="Item"/>
<item
android:id="#+id/menu_settings"
android:title="Settings" />
</menu>
I tried various solution to get toolbar title but none of them worked. like using and others. What went wrong with my code. can you advice. I m getting menu and their options but Title of toolbar no luck.
getSupportActionBar().setDisplayShowTitleEnabled(true);
getSupportActionBar().setTitle("Hello");
Below is my style.xml code:

You can set title to toolbar for reference no need to get toolbar of support.
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle("Hello");
setSupportActionBar(toolbar);
}

android:fitsSystemWindows is for making status bar and/or navigation bar transparent. I am not aware that it can be applied to Toolbar.
As for changing navigation bar's colour part, you can do it like this:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
// clear FLAG_TRANSLUCENT_STATUS flag:
window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
// add FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS flag to the window
window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
// finally change the color
window.setStatusBarColor(rgbColor);
}
And for Toolbar you can do it in XML by setting app:contentScrim="?attr/colorPrimary" property to CollapsingToolbarLayout, or in code:
collapsingToolbarLayout.setContentScrimColor(toolbarColor);
collapsingToolbarLayout.setExpandedTitleColor(textColor);
collapsingToolbarLayout.setCollapsedTitleTextColor(textColor);
I'm trying to change the colour of section titles but I can find any options within the xml nor java as I type. The title is called 'Section' but appears in black hence I cannot see it. How can it be changed to white?

Subheaders use the android:textColorSecondary from your theme for the text color - make sure this is set to a light color (as would be the default for Theme.AppCompat.NoActionBar).
