Why is there 2 title bars in my activity when using navigation drawer in Marshmallow device

When I run my app in devices lower than marshmallow devices it shows only one title bar. But when I try it in marshmallow devices the navigation drawer is present in the second title bar.Like this.
Can someone Tell me how to fix this?
My MainActivity, activity_main, manifest and style are given below.
Thank You.

you are missing this:setSupportActionBar()
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
setSupportActionBar(toolbar);
in values/styles.xml:
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
Apply the theme: for ur activity in manifest
in manifest:
<activity
android:name=".Oodo.CaseSheets.MainActivity"
android:theme="#style/AppTheme.NoActionBar" //change here

I finally fixed it.
What I did was:
1.Deleted the toolbar from the layout
2.Changed my MainActivity like this. refer here
public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
setTitle("Case Sheets");
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerToggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close) {
#Override
public void onDrawerClosed(View drawerView) {
super.onDrawerClosed(drawerView);
}
#Override
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
}
};
drawer.post(new Runnable() {
#Override
public void run() {
mDrawerToggle.syncState();
}
});
drawer.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
myDB = MainActivity.this.openOrCreateDatabase("hoteldb", MODE_PRIVATE, null);
mRecyclerView = (RecyclerView) findViewById(R.id.recycler_view);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.setItemAnimator(new DefaultItemAnimator());
mRecyclerView.addItemDecoration(new DividerItemDecoration(getApplicationContext()));
try {
showList();
}catch (Exception e)
{
Toast.makeText(getApplicationContext(),"Please Synch the data",Toast.LENGTH_SHORT).show();
}
} catch (Exception e) {
e.printStackTrace();
Toast.makeText(getApplicationContext(),"Please Login",Toast.LENGTH_LONG).show();
Intent logout = new Intent(MainActivity.this, LoginPage.class);
startActivity(logout);
}
}
And Kept the theme of the activity as Apptheme itself.
It worked on both marshmellow and lolipop devices..
#rafsanahmad007..Thank u for helping.

add this setSupportActionBar(myToolbar); after toolbar initialisation.

Navigation drawer icon not showing

I'm building Xamarin Android application and I want to implement right navigation drawer with drawer toogle in a custom action bar. Everything is working (drawer slides from right side,...) except one thing: the navigation drawer icon is not showing.
So, this is my Activity.axml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.widget.DrawerLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:id="#+id/drawerLayout">
<!-- Main Content -->
<FrameLayout xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
android:id="#+id/map" />
...
</FrameLayout>
<!-- Right Navigation Drawer -->
<LinearLayout
android:orientation="vertical"
android:layout_width="250dp"
android:layout_height="match_parent"
android:layout_gravity="right"
android:background="#f2f2f2">
...
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
</RelativeLayout>
And this is my Activity.cs:
using Android.Support.V4.App;
using Android.Support.V4.Widget;
...
public class Activity : Activity
{
...
private DrawerLayout mDrawerLayout;
private ActionBarDrawerToggle mDrawerToogle;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
ActionBar.SetDisplayShowHomeEnabled(false);
ActionBar.SetDisplayShowTitleEnabled(false);
ActionBar.SetCustomView(Resource.Layout.CustomActionBar);
ActionBar.SetDisplayShowCustomEnabled(true);
SetContentView(Resource.Layout.Activity2);
mDrawerLayout = FindViewById<DrawerLayout>(Resource.Id.drawerLayout);
mDrawerToogle = new ActionBarDrawerToggle(this, mDrawerLayout, Resource.Drawable.ic_drawer,Resource.String.open_drawer_layout, Resource.String.close_drawer_layout);
mDrawerLayout.SetDrawerListener(mDrawerToogle);
ActionBar.SetDisplayHomeAsUpEnabled(true);
ActionBar.SetHomeButtonEnabled(true);
...
}
protected override void OnPostCreate(Bundle savedInstanceState)
{
base.OnPostCreate(savedInstanceState);
mDrawerToogle.SyncState();
}
public override void OnConfigurationChanged(Configuration newConfig)
{
base.OnConfigurationChanged(newConfig);
mDrawerToogle.OnConfigurationChanged(newConfig);
}
public override bool OnOptionsItemSelected(IMenuItem item)
{
if (mDrawerToogle.OnOptionsItemSelected(item))
{
return true;
}
return base.OnOptionsItemSelected(item);
}
...
}
This is my Themes.xml:
<resources>
<style name="CustomActionBarTheme"
parent="#android:style/Theme.Holo.Light.DarkActionBar">
<item name="android:actionBarStyle">#style/ActionBar</item>
</style>
<style name="ActionBar"
parent="#android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:height">75dp</item>
<item name="android:background">#00000000</item>
</style>
</resources>
Am I doing something wrong? Any help is appreciated.
UPDATE
My CustomActionBar has app icon and app title. Is this maybe interrupting navigation drawer icon?

This is the solution I have found.
First, you need to add action_bar.xml file with the following content to the menu folder:
<?xml version="1.0" encoding="utf-8" ?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/personalInfoActionBar"
android:title="Informations"
android:icon="#drawable/infoIcon"
android:showAsAction="always"/>
</menu>
Then insert this code in your activity:
public override bool OnOptionsItemSelected(IMenuItem item)
{
if (item.ItemId == Resource.Id.personalInfoActionBar)
{
if (mDrawerLayout.IsDrawerOpen(mRightDrawer))
{
mDrawerLayout.CloseDrawer(mRightDrawer);
}
else
{
mDrawerLayout.OpenDrawer(mRightDrawer);
}
return true;
}
return base.OnOptionsItemSelected(item);
}

Don't forget call actionbarDrawerToggle.syncState()

Only lower half of the Action Bar is showing (and it is behind the status bar)

For some reason only the lower half of the ActionBar is being displayed, and the half that is showing is behind the status bar. Why could this happen?
This happens only in the DrawerActivity.
It must be something with the newer versions of Android because I noticed the bug in Android 5.0.2 and 6.0. In Android 4.4.4 there is no issue.
I'm extendig my Activity from the android.support.v7.app.AppCompatActivity and implementing some fragments in it.
This is my app configuration:
android {
compileSdkVersion 22
buildToolsVersion "21.1.2"
defaultConfig {
applicationId "com.mypackage.myapp"
minSdkVersion 15
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
The layout for the DrawerActivity
<?xml version="1.0" encoding="utf-8"?>

</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
onCreate method of DrawerActivity:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
//Setting floating button
FloatingActionButton fab = (FloatingActionButton) 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 = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
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_view);
navigationView.setNavigationItemSelectedListener(this);
//Setting up default fragment.
Fragment fragment = HomeFragment.newInstance(null, null);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.mainFrame, fragment);
ft.commit();
}
Here's a screenshot for better understanding:
Thank you!

Add this line in your oncreate
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
//then set status bar color or any thing else
}

Notification Bar is grey after implementing Nav Drawer

I am trying to learn implementations of Navigation Drawer in Android.
In one activity, i have made the Navigation Drawer come under the Status Bar(transparent) and over the App Bar and everything works fine.(left Screenshot)
In another activity in the same App, i am trying to create Navigation Drawer that pulls up under the App Bar. But here, the status bar turns grey for some reason(whether nav drawer is open or closed)(Right Screenshot). Other than this, everything seems fine.
Below is the screenshot:
The green Nav Drawer is a fragment.
What i want to know is how to make the status normal(darker shade of. Please remember, if i click that twin arrow icon in the App Bar, it will take me to another activity which contains another Nav Drawer which works like the one in Material Design(Full height of the screen and comes under a transparent Status Bar). This is shown in the left side of the screenshot.
Below is the code:
MainActivity.java:
public class MainActivity extends ActionBarActivity {
Toolbar toolbar;
DrawerLayout xDrawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_alt);
toolbar = (Toolbar) findViewById(R.id.app_bar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
xDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
xDrawerLayout.setStatusBarBackgroundColor(getResources().getColor(R.color.primary_dark));
NavDrawerFragment mfragment = (NavDrawerFragment) getFragmentManager().findFragmentById(R.id.nav_drawer_fragment);
mfragment.SetUp(xDrawerLayout, toolbar, R.id.nav_drawer_fragment);
}
...

Colors.xml(screenshot showing color samples):
Note: I do not want to compromise on the styles etc that would render my other navigation drawer not working. In other words, i prefer a solution wherein both types of navigation bar works as expected in the same app.
Please let me know if you need any info and i shall edit if required.
Edit: added app_bar.xml & colors.xml for clarity.

But here, the status bar turns grey for some reason
It's the translucent (25% black) status bar background over the white background of activity underneath it.
What i want to know is how to make the status normal
You need to disable translucent status bar for the second activity. It is activated by this line in your theme definition:
<item name="android:windowTranslucentStatus">true</item>
<item name="android:statusBarColor">#color/primary_dark</item>
So either define a child theme and override the flag with false or clear the flag programmatically by calling this from your activity:
if (Build.VERSION.SDK_INT >= 21) {
getWindow().clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
getWindow().setStatusBarColor(getResources().getColor(R.color.primary_dark);
}

Not able to add NavigationDrawer using MaterialDesign

I have written the following code to add drawer layout in my material design theme which is not showing up. Just the tool bar is showing up.

I missed out certain important statements in my activity. Here is the complete activity the remaining stays the same. With following changes I was able to add the new NavigationDrawer
