Toolbar disappears immediately after launching Activity

I originally had an ActionBar atop my Google Map Activity, but I needed to add multiple elements inside it, so it was suggested to me that I use a Toolbar instead.
Well, I've managed to successfully get it setup, but the Toolbar disappears immediately after launching.
I don't understand why this is happening since there are no errors, and I don't know where I would try to add a breakpoint in my code.
Here's the code in my onCreate method of my MapActivity.java:
/*
CODE FOR DISTANCE TEXT AND SHARE BUTTON
*/
if(getSupportActionBar() != null) {
getSupportActionBar().setDisplayShowTitleEnabled(false);
}
Toolbar toolbar = findViewById(R.id.toolbar);
mDrawerLayout = findViewById(R.id.nav_drawer);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mToggle = new ActionBarDrawerToggle(this,mDrawerLayout,toolbar,R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
mNavigationView = findViewById(R.id.navigation_view);
if(mNavigationView != null) {
mNavigationView.setNavigationItemSelectedListener(this);
}
Here are the activities in my AndroidManifest.xml

After reading about layouts, I realized I forgot about z-ordering!
I changed my code from this:

to this:

<!-- PLACED IT UNDER THE FRAGMENT -->

Now the toolbar is there. :-)

android change actionbar to toolbar

I am trying to change Actionbar to Toolbar, I have successfully added Toolbar and removed Actionbar, but now the problem I have is that on my layout there will be a blank space above my toolbar where the Actionbar was at before. How can I move my Toolbar up so that it aligns with the top of the screen?
I changed style to:
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>

Hope its help.:)

Did you call setSupportActionBar?
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(getLayoutResource());
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
if (toolbar != null) {
setSupportActionBar(toolbar);
}
}
See this for a complete guide: material-design-everywhere

First disable the ActionBar within res/styles.xml:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
</style>
</resources>
Include ToolBar in Activity layout file:
<LinearLayout
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:fitsSystemWindows="true"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:minHeight="?attr/actionBarSize"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:titleTextColor="#android:color/white"
android:background="?attr/colorPrimary"/>
</LinearLayout>
In your Activity:
public class MyActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_my);
// Find the toolbar view inside the activity layout
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
// Sets the Toolbar to act as the ActionBar for this Activity window.
// Make sure the toolbar exists in the activity and is not null
setSupportActionBar(toolbar);
}
Note:
You'll want to add android:fitsSystemWindows="true" to the parent layout of the Toolbar to ensure that the height of the activity is calculated correctly.
When using the support library, make sure that you are importing android.support.v7.widget.Toolbar and not android.widget.Toolbar.
I include this information from here. Refer this for more.

Try to put theme for that activity in AndroidMenifiest.xml file like
<activity
android:name=".SplashActivity"
android:label="#string/app_name"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.Light.NoActionBar" />

Toolbar's shadow on status bar for Lollipop

I'm using a template from Android Studio that used AppCompat Toolbar. Unfortunately, the toolbar casts shadow on the status bar so it doesn't look right.I also implement a NavigationDrawer so I can't simply set the color of the status bar.
This is how it looks:
This is how it should be:
activity_main.xml
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

</style>
</resources>

Put a LinearLayout in like this:
<android.support.design.widget.CoordinatorLayout 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"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".ui.activities.MainScreenActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main_screen" />
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>

This shadow is part of windowContentOverlay on APIs below LOLLIPOP (on LOLLIPOP it's #null).
When you work with Toolbar widget the toolbar isn't part of window decor anymore so the shadow starts at the top of the window over the toolbar instead of below it (so you want the windowContentOverlay to be #null). Additionally you need to add an extra empty View below the toolbar pre-LOLLIPOP with its background set to a vertical shadow drawable (8dp tall gradient from #20000000 to #00000000 works best). On LOLLIPOP you can set 8dp elevation on the toolbar instead.

I tried all the other answers and none worked. What fixed it was adding this to the AppBarLayout:
app:elevation="0dp"

That's because of :
<item name="android:statusBarColor">#android:color/transparent</item>
i guess.
Got it, check this:
http://developer.android.com/training/material/theme.html#StatusBar
To set a custom color for the status bar, use the
android:statusBarColor attribute when you extend the material theme.
By default, android:statusBarColor inherits the value of
android:colorPrimaryDark.
And you've set it to transparent.this is not a good way for doing that since Google put this code for you:
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
And also, instead of:
<style name="AppTheme.NoActionBar">
Use this and add a parent and check:
<style name="AppTheme.NoActionBar" parent="Theme.AppCompat.Light.NoActionBar">

To get the correct behavior, you will need to remove
android:fitsSystemWindows="true"
From android.support.design.widget.CoordinatorLayout
In your styles.xml, color defined in colorPrimaryDarkwill be used for drawing the notification bar.
You will need to have styles.xml in your values-v21 folder with following item in your styles:
<item name="android:statusBarColor">#android:color/transparent</item>
Hope this helps.

activity becomes fullscreen when toolbar is transparent

I am trying to use a transparent toolbar in my app. However, when I set my toolbar as transparent the activity expands to fullscreen height and some content overlaps with my toolbar.
Here is the layout code for the activity:
app_bar_main.xml :
<?xml version="1.0" encoding="utf-8"?>

Try adding this to your relative layout xml
android:paddingTop="?android:attr/actionBarSize"

You can try with this:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#00FFFFFF">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"/>
</android.support.v7.widget.Toolbar>

You are using a RelativeLayout as parent container in app_bar_main.xml where all children will occupy the entire view if set to match parent. You can change it to LinearLayout with vertical mode where Android will arrange the children one by one in vertical direction without overlap.

Try adding this:
<include layout="#layout/content_main" android:layout_below="#+id/toolbar" />

android - Bug Status Bar and navigation Bar TRANSPARENT

I have a problem with the translucent statusbar only when opening of the app for the first time. Take a look at the screenshot:
http://i1335.photobucket.com/albums/w673/ductruongcntt/Screenshot_2014-06-26-14-17-26_zps1e9a56f4.png
Here is the XML of the Style I use which is including the translucent Status Bar:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
android:fitsSystemWindows="true"
android:orientation="vertical" >
<com.viewpagerindicator.PagerSlidingTabStrip
android:id="#+id/indicatorTabHome"
android:layout_width="match_parent"
android:layout_height="40dp"
android:clipToPadding="false"
android:fitsSystemWindows="true" >
</com.viewpagerindicator.PagerSlidingTabStrip>
<android.support.v4.view.ViewPager
android:id="#+id/vpMain"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</android.support.v4.view.ViewPager>
and my theme:
<style name="MyTheme" parent="#android:style/Theme.Holo.Light">
<item name="android:windowContentOverlay">#null</item>
<item name="android:windowTranslucentStatus">true</item>
</style>

Put this inside your activity tag in the manifest. This'll ensure that the app opens full screen.
android:label="#string/app_name"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen"
