I'm trying to get rid of the elevation under the toolbar by using app:elevation="0dp" but it only works in the main activity xml. When I go to other activities I can still see the elevation, any ideas how to completely get rid of the elevation under my toolbar?

this is what I got after including toolbar in other activities layouts
I ran into this problem before, and it looks like you're using a theme that doesn't extend #style/Theme.AppCompat.NoActionBar. When you're using a Toolbar in your XML layout, you have to hide the default ActionBar so they don't conflict.
In your AndroidManifest.xml, make sure you set the theme for the activity you're having a problem with:
<application ...>
<activity ...
android:theme="#style/AppTheme.NoActionBar">
</activity>
</application>
In your activity XML, just add app:elevation="0dp" attribute to AppBarLayout. This will cause no elevation to all fragments under this activity. Here, I use a frame layout for the fragment containers.
<layout xmlns:android="http://schemas.android.com/apk/res/android"

ScreenShot : Child layout not having tablayout
But the problem is toolbar menu icon for drawer is not showing up its hiding behind the child toolbar. So any idea what is problem in my layout.
Thanks
You are overriding the Parent Activity toolbar in your Bottom Navigation View- Fragment 1
Change your layout to remove the toolbar..
BottomNavFragment1.xml
<?xml version="1.0" encoding="utf-8"?>
<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="wrap_content"
android:orientation="vertical">
<android.support.design.widget.TabLayout
android:id="#+id/tab_layout"
app:tabGravity="fill"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#3b5998"
android:minHeight="?attr/actionBarSize"
app:tabIndicatorColor="#c8130d"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar" />
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
</android.support.v4.view.ViewPager>
</LinearLayout>
EDIT
In your activity layout use layout_below attribute for your FrameLayout
ParentLayout.xml
<FrameLayout
android:id="#+id/container"
android:layout_below = "#+id/appBarLayout" //add this
android:layout_width="match_parent"
android:layout_height="match_parent" />
otherwise it will replace the whole layout including the toolbar in your parent.
I am currently using CollapsingToolbar Layout in the upper portion of my layout. I want to collpase a particular portion (LinearLayout only) and keep the toolbar fixed on the top. I was able to fix the Toolbar position on top in another project and keep it from collapsing. However, for some reason, I am not able to fix the position of my toolbar. Any help will be appreciated. Here is my the XML of the layout:

I am loading another fragment on the ViewPager. and I am using the following code to load the toolbar.
findViewById(R.id.toolbar). setBackgroundResource(R.drawable.dark_primary_no_radius);
setSupportActionBar((android.support.v7.widget.Toolbar)findViewById(R.id.toolbar));
And here is UPDATED the result:
As you can see, in the second image, toolbar collapsed on the top. Any help will be highly appreciated.
Thank you.
You need to use the app:layout_collapseMode="pin" in Toolbar only.
Remove this from other components like the LinearLayout and CollapsingToolbarLayout.

I'm trying to add a simple SearchView to the toolbar in my app. Everything it's working fine expect for the layout.
There is this "space" between the NavigationDrawer icon and the SearchView.
If I set a title the space is filled with that string, otherwise is empty.
Empty string:
With a string in title:
How do I remove that annoying empty space?
Edit:
I'm using as base code the NavigationDrawer example from Android Studio

Toolbar extends from FrameLayout and you can put views inside it. Like this:
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toolbar"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/primary_color">
<SearchView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</android.support.v7.widget.Toolbar>
Edit: You put it inside the layout as a menu. It always will be on the right side of the toolbar, because it is a menu. If you want to have a more direct control over views inside a toolbar, just put it there as I did show you.
I have set actionBar.setDisplayHomeAsUpEnabled(true) in code. So only adding SearchView in the toolbar didn't work for me and there is some extra space between Navigation Back and SearchView. I don't have Title in Toolbar. So I customized whole toolbar like this:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_alignParentTop="true" // If parent layout is RelativeLayout
android:background="?attr/colorPrimary"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:contentInsetLeft="0dp" // This is important,
app:contentInsetStart="0dp" // Otherwise there will be extra space on Left Side
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:orientation="horizontal">
<ImageView
android:id="#+id/ivNavBack"
android:layout_width="56dp"
android:layout_height="56dp"
android:background="#drawable/your_drawable" // Custom background (optional), if you want to have a press effect
android:padding="16dp"
android:src="#drawable/ic_nav_back" /> // You can set icon of your choice here
<android.support.v7.widget.SearchView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:queryHint="#string/search_view_hint"
app:queryHint="#string/search_view_hint" />
</LinearLayout>
</android.support.v7.widget.Toolbar>
...& in your Activity:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
SearchView searchView = (SearchView) toolbar.findViewById(R.id.searchView);
searchView.onActionViewExpanded(); // Expands searchView by default
// If this is not set, then you will see default search icon and you have to click it to expand SearchView.
Now no need to set actionBar.setDisplayHomeAsUpEnabled(true) in code. Just handle click event of ivNavBack for it.
EDIT: Problem solved. See Blackbelt's comment
I've been trying to implement the collapsing toolbar into my project, sticking to an example provided by Google. I've gotten it to work for the most part, but views are appearing on top of the toolbar rather than below them.
Below, I've pasted the XML code for the activity that hosts the toolbar.
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

app:layout_scrollFlags="scroll|exitUntilCollapsed">

android:layout_height="match_parent"
android:scaleType="fitXY"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax"
android:id="#+id/toolbarImage"
/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/item_detail_container">
</FrameLayout>
<android.support.design.widget.FloatingActionButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/btn_star_big_off"
app:layout_anchor="#id/app_bar"
app:layout_anchorGravity="bottom|end"
android:scaleType="center"
app:backgroundTint="#ffffff"/>
Note that the FrameLayout with id item_detail_container will contain a fragment.
Said fragment uses to the following XML file:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView
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"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/activity_movie_details"
tools:context="android.jochemkleine.com.popularmovies.ui.m"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST TEXTVIEW"
/>
</LinearLayout>
Note that right now, the LinearLayout in this XML file serves no purpose at all, because there is only one TextView present. It will however be of use later, as NestedScrollView can only host one direct child.
I am fairly sure that the fault lies somewhere within the first XML file, likely with the use of the FrameLayout. What baffles me is that the Google example does it almost exactly the same way, the only difference is that they include a layout, instead of using a FrameLayout.
Thanks in advance; any and all help is appreciated.
