Always used linear layout for continuous Views and use Framelayout or Relative Layout when you what to show something position like right or bottom.

Try this out,
android:fillViewport="true"
for eg:
<ScrollView
android:layout_width="match_parent"
android:fillViewport="true"
android:layout_height="wrap_content">
</ScrollView>
it may help you.

Ypu are using fill_parent which is deprecated now you should use match_parent
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">
Change it to
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" // you can add this line too but it should work without it

How to make box layouts and fit on full screen and full height

Height is not fitting in different devices.
Here is the code:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal">
<include android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:id="#+id/left_center"
layout="#layout/card_center_top" />
<include android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:id="#+id/right_"
layout="#layout/card_center_right" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal">
<include android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:id="#+id/left_bottom"
layout="#layout/card_left_bottom" />
<include android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:id="#+id/right_bottom"
layout="#layout/card_right_bottom" />
</LinearLayout>
It is not fitting on every device and don't know how to make this happens. Thanks in advance.

create below hierarchy. I have set Black and White box so you can understand easy way.
Xml Code :
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/red1"
android:orientation="vertical"
android:weightSum="3">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:background="#FFFFFF"
android:layout_weight="1"

android:layout_height="match_parent"
android:background="#FFFFFF"
android:layout_weight="0.5">

Output :

Use relative layout concept

Eihschnaehkeee is right -- you just need a layout that allows overlapping. Here is XML to try (also adding right margin for your button):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:fab="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#0000">
<br.com.test.common.view.SlidingTabLayout
android:id="#+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true" />
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/sliding_tabs"
android:layout_alignParentBottom="true"
android:background="#0000"/>
<com.getbase.floatingactionbutton.FloatingActionButton
android:id="#+id/pink_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
fab:fab_icon="#drawable/ic_add"
fab:fab_colorNormal="#color/material_orange_500"
fab:fab_colorPressed="#color/material_orange_a200"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_marginBottom="16dp"
android:layout_marginRight="16dp"/>
</RelativeLayout >

Eihschnaehkeee and Bruce.
I tried to put as relative layout and swipe funcinou not more, I tried using SlidingTabLayout the android code https://github.com/googlesamples/android-SlidingTabsBasic/

how to align parent bottom in android linear layout?

I have a linearlayout
and I want to create at the bottom of it a slice.
I know there are some options, but I'm a bit confused
1) android:layout_gravity:"bottom" --> this doesn't work for me for some reason.
2) android:gravity_weight="0" and give the sibling before it android:gravity_weight:"1"
3) android:height="wrap_content" and give the sibling before it android:height:"match_parent"
I know how to do this using relativeLayout, but I want to practice linearLayout
what would you suggest?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/blue_bg"
android:orientation="vertical" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:src="#drawable/signup_illu_why" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight=""
android:orientation="horizontal" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/signup_skip_icon" />
</LinearLayout>

Actually, you can set the parent element's gravity to bottom
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/blue_bg"
android:orientation="vertical"
android:gravity="bottom" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:src="#drawable/signup_illu_why" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight=""
android:orientation="horizontal" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/signup_skip_icon" />
</LinearLayout>

<LinearLayout
android:orientation="vertical"
... >
<Space
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<SomeViewThatNeedsGoBottom
... />
</LinearLayout>

try this
<?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="match_parent"
android:background="#ffffff"
android:orientation="vertical" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="vertical" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
</LinearLayout>
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/black"
android:orientation="vertical"
android:weightSum="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_weight="0.8" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="0.2" />
</LinearLayout>

surround your linear layout with framelayout and give gravity as bottom..
its simple than you think... many layouts are used just for easier move towards design
<FrameLayout
android:layout_height="fill_parent"
android:layout_width = "fill_parent">
<LinearLayout`
android:layout_height="wrap_content"
android:layout_width = "wrap_content"
android:layout_gravity = "bottom"
android:orientation = "vertical">
<Button
android:layout_height="wrap_content"
android:layout_width = "wrap_content"
android:text = "btn"/>
</LinearLayout>
</FrameLayout>
`

Use:
android:gravity="bottom"
example:
<LinearLayout
android:layout_weight="7"
android:layout_width="0dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="5">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="some text"
android:layout_weight="2"
android:gravity="bottom" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="some text"
android:layout_weight="1" />
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="some text"android:gravity="center"
android:layout_weight="2" />
</LinearLayout>

Put Relative in LinearLayout
and set Relative to matchparent, so you can use the layoutalignparentbottom
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/blue_bg"
android:orientation="vertical" >
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_marginTop="5dp"
android:src="#drawable/signup_illu_why" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight=""
android:orientation="horizontal" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:src="#drawable/signup_skip_icon"
android:layout_alignParentBottom="true" />
</RelativeLayout>
</LinearLayout>
