How can I prevent the truncation of a listview by the layout header?

I cannot see the first row of my listview. I am assuming the screen page's header is overlapping with the listview.
My fragment file is follows:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView 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"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="?attr/layout_background_color">
<LinearLayout
android:id="#+id/colors_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="visible">
<ListView
android:id="#+id/colors_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
Any advice tips will be very helpful.
Edit: I am including my activity file below.
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout
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: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"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<fragment
android:id="#+id/color_fragment"
android:name="com.microsoft.skype.teams.views.fragments.ColorFragment"

android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.constraint.ConstraintLayout>
As a hack I am currently adding an extra row of data. Adding the extra row of data is clearly something I wish to avoid.

The issue is your toolbar is taking the height of your first row. To get out of this do something like this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView 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"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="?attr/layout_background_color">
<LinearLayout
android:id="#+id/colors_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?attr/actionBarSize" // added this line now your
android:orientation="vertical" listview will start below
android:visibility="visible"> toolbar
<ListView
android:id="#+id/colors_list"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</android.support.v4.widget.NestedScrollView>

My tab one layout: I try to change ScrollView to android.support.v4.widget.NestedScrollView , it's still no working.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">

Here is my tab layout setting:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

style="#style/AppTabLayout"
app:tabTextAppearance="#style/AppTabTextAppearance"
android:background="#color/appColor"
app:tabTextColor="#android:color/white"
app:tabGravity="fill"/>
</LinearLayout>
I had add like app:layout_behavior="#string/appbar_scrolling_view_behavior" and android.support.v4.widget.NestedScrollView why its still no working ?
Any help would be appreciated . Thanks in advance.

That's because you haven't set the scroll flags in toolbar. Use the following code for your toolbar
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"/>

(tablayout) Tabs come over the keyboard when editText is focused

I have setUp tabLayout with ViewPager which has 5 Fragments.
tabLayout with android:layout_gravity set to bottom . Third fragment has editText which when focused , my tabs come over the keyboard.
Tablayout without EditText
TabLayout with EditText
Main layout :
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/coordinatorLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<include
android:id="#+id/t"
layout="#layout/toolbar"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewPager"
android:layout_width="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"/>
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tab="http://schemas.android.com/tools"
android:layout_gravity="bottom"
app:tabGravity="fill"
android:background="#color/colorPrimary"
android:layout_alignParentBottom="true"
android:id="#+id/tabs"
app:layout_collapseMode="parallax"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
xmlns:android="http://schemas.android.com/apk/res/android">
</android.support.design.widget.TabLayout></android.support.design.widget.CoordinatorLayout>
Third Fragment layout :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="40dp"
android:hint="Enter something"
/>
</LinearLayout>

Open AndroidManifest.xml and add to your activity tag
android:windowSoftInputMode="adjustPan"
If this doesn't work add
android:windowSoftInputMode="adjustNothing"
This will prevent the soft keyboard from adjusting the layout.
Hope this helps.

Put The TabLayout under the ToolBar and aove the ViewPager

Custom MaterialSearchView Displayed Under Toolbar in a Fragment

I'm using a custom MaterialSearchview, and my project is as the following :
Layouts:
MainLayout
FragmentSection Layout
Codes :
MainActivity
SectionFragment
In the MainActivity there's a Drawer library, i have 6 sections, only one of those fragments has a Search icon, so here's my problem .
In main layout i have a toolbar and a fragment :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.abohani.ramadantime.MainActivity">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways|snap"
android:minHeight="#dimen/abc_action_bar_default_height_material"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<FrameLayout
android:id="#+id/fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:layout_below="#+id/toolbar" />
</RelativeLayout>
As you can see, the fragment is under the toolbar, so when the transaction is made, the Search shows under the toolbar, why ?
because i'm adding the searchview in my fragment layout, and i'm repalcing the MainLayout #id/fragment with my fragment layout, and that fragment view is under toolbar => Searchview shows under .
What do i need ? i'd like a help to fix this, a different logic on it ?
Here's my fragment layout :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/rel"
android:orientation="vertical">
<com.lapism.searchview.SearchView
android:id="#+id/searchView"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<android.support.v7.widget.RecyclerView
android:id="#+id/fav_rv"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/no_match"
android:visibility="invisible"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
<include
android:id="#+id/loading_layout"
layout="#layout/loading_progress"/>
</RelativeLayout>

Fragment from View Pager hiding behind Tab Bar

I am having an issue with a Tab bar and ViewPager in my android project. What the app does it has an activity which hosts a tab layout and then has 2 fragment which represents each of the tabs.
When the activity is opened it posts to an API to get some data and puts the data into a data adapter for a Recycler View and Card layout in each of the fragments.
The recycler view will contain 3 items but only 2 are being shown as the first is being hidden under the toolbar and/or the tab bar as shown in the screenshot below.
Below is the layout file of my activity
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.BoardiesITSolution.CritiMonApp.AppsActivity">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include layout="#layout/toolbar" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="fixed"
app:tabGravity="fill" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<!--app:layout_behaviour="#string/appbar_scrolling_view_behaviour" />-->
</android.support.design.widget.CoordinatorLayout>
Below is the layout of the fragment
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<view
android:id="#+id/recycler_view"
class="android.support.v7.widget.RecyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true" />
</LinearLayout>
Below is the layout for card layout
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:cardview="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="80dp"
android:layout_margin="8dp">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="80dp"
android:elevation="5dp">
<TextView
android:id="#+id/txtApplicationName"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:maxLines="3"
android:padding="8dp"
android:textColor="#222"
android:textSize="15dp"
android:layout_centerInParent="true"/>
</RelativeLayout>
</android.support.v7.widget.CardView>
Below is the screenshot as mentioned above which shows the problem. I've pixelated some of the text but it should you what I mean, there should be 3 items but the first item is hiding underneath the tab bar.

Edit: As suggested below by #smeet and #hardik, adding the scroll behavior app:layout_behavior="#string/appbar_scrolling_view_behavior" should fix the problem while preserving the scroll behavior. Scroll behaviors only work if the view is a direct child of the coordinator layout.
Old Answer
Just Wrap your appbar layout and viewpager in a vertical LinearLayout
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context="com.BoardiesITSolution.CritiMonApp.AppsActivity">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
//appbar layout
//viewpager
</LinearLayout>
</android.support.design.widget.CoordinatorLayout>
From the docs, CoordinatorLayout is a super-powered FrameLayout. So you can expect the typical "lay views on top of other views" FrameLayout behavior.

Adding :
app:layout_behavior="#string/appbar_scrolling_view_behavior"
in ViewPager resolved issue in my case.

if we will wrap app bar layout with linear layout than toolbar will not hide when you scroll so accepted answer might not help you if you want to hide toolbar when you scroll.
Smeet did it right way but not explained! here is full example with explanation.
add app namspace to CoordinatorLayout
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
......
>
and just add below line in your ViewPager
app:layout_behavior="#string/appbar_scrolling_view_behavior"
complete xml will be as below
<?xml version="1.0" encoding="utf-8"?>
<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"
