scrollable tabs custom user Interface

I am working on a Scrollable tabs and came to observe a custom scrollable tabe in a mediaplayer app but don't know what is used in this as per my knowledge it is like scrollable tabs.Any hint how to achieve this while changing from one fragment to another .I want to show a gape in the fragment while scrolling as in this app?THIS is what I created
this is what i want a gape between two fragment
I tried to give padding in the view pager but it is not working at all.
my layout content main .xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.view.ViewPager android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:background="#drawable/gradient2"
>
<android.support.v4.view.PagerTitleStrip
android:id="#+id/title"
style="#style/viewPagerTitleStrip"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_gravity="top"
android:paddingTop="4dp"
android:paddingBottom="4dp"
android:background="#drawable/gradient1">
</android.support.v4.view.PagerTitleStrip>
</android.support.v4.view.ViewPager>
I tried both padding and margine in the ViewPager but it is not working

Here is the similar property used try this https://github.com/astuetz/PagerSlidingTabStrip
Since I am using ViewPager, the easiest way to achieve some space is to use the setPageMargin() method of Viewpager, which in my case will be
ViewPager pager = (ViewPager) findViewById(R.id.pager);
pager.setPageMargin(200);
//200 is value in pixel
There is also a method setPageMarginDrawable() sets a drawable that will be used to fill the margin between pages (Android documentation).

Is there any way to have embedded scrollable tabs?

I have a layout in my head that should look like that: http://i.imgur.com/H1nTRvd.png
Only part that will be dynamic is the blue one. I don't know the number of tabs that will be created before I load the activity, hence the number is acquired from server (could be either 5 or 24 for all I know).
The bottom buttons should not move when I swipe and the blue area changed.
Currently I have this implemented w/o tabs list using embedded fragment in my activity and gesture listener. There's no good looking transaction animation between fragments.

#Nick Pakhomov: You can use PagerTabStrip
PagerTabStrip
is intended to be used as a child view of a ViewPager widget in your XML layout. PagerTabStrip is most often used with fragment, which is a convenient way to supply and manage the Lifecycle of each fragment.
So here’s how a ViewPager with a PagerTabStrip in it would look like in the layout file:
<android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.PagerTabStrip
android:id="#+id/pager_tab_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#33b5e5"
android:textColor="#fff"
/>
</android.support.v4.view.ViewPager>
Please check this PagerSlidingTabStrip demo . I hope it will helps you .

Overlay view like YouTube app

I am creating an app which does some tracking on a map. The tracking part works great inside my activity.
However, I want to have some kind of small overlay in the bottom right corner (like the minimalised video playback in the YouTube app) that stays there, even when I switch activities.
I have looked at this, but it's not really what I need. I don't need it to be moveable, and I think this is impossible to keep when switching activities.
Is there some kind of class that I can implement (Widget, Fragment, ...) that would fit my needs?
Thank you,

This is a bit late and probably not relevant to you anymore, but maybe somebody else will find this helpful.
I don't think it's possible to switch activities and keep a certain view on screen. How I think this should be done is have a main activity with fragments that swap and in the activity's layout have a view overlay on top of the fragments container.
For example:
<?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"
tools:context=".MainActivity">
<!-- Container for the fragments -->
<FrameLayout
android:id="#+id/fragment_container"
android:layout_below="#id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<!-- This view will overlay the fragment in the bottom right corner -->
<View
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</RelativeLayout>

Swipe part of the page using pager view

I have ViewPager with PagerTabStrip , when swiping from page to another, both the pager and the tab will be moving together. (like google paly)
It's working fine. now all the pages have common data, and one part is going to change when swiping, so i don't want to swipe the whole page, just the area that going to change.
As you can see in the following image just the red area will be effected when swipe pages, the green area will not move.
I've searched a lot, but i can't find anything useful, any help would be appreciated.
viewpager code:
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.PagerTabStrip
android:id="#+id/pager_title_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#FFFFFF"
android:textColor="#003366"
android:paddingTop="4dp"
android:paddingBottom="4dp"/>
</android.support.v4.view.ViewPager>

Using swipeyTabs is the answer.
The problem when using PagerTabStrip is that the PagerTabStrip will be inside the ViewPager tag see the following code:
<android.support.v4.view.ViewPager
android:id="#+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v4.view.PagerTabStrip
android:id="#+id/pager_title_strip"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="top"
android:background="#FFFFFF"
android:textColor="#003366"
android:paddingTop="4dp"
android:paddingBottom="4dp"/>
</android.support.v4.view.ViewPager>
so you cant separate them form each other.
but when using the SwipeyTabs, each tag will be as a separate part, see the following code:
<net.peterkuterna.android.apps.swipeytabs.SwipeyTabs
android:id="#+id/swipeytabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
swipeytabs:bottomBarColor="#ff96aa39"
swipeytabs:bottomBarHeight="2dip"
swipeytabs:tabIndicatorHeight="3dip"
android:background="#ff3b3b3b"/>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1" />
In this case, you can customize your layout as you want by dealing with ViewPager and SwipeyTabs as two parts.
In your case, I guess you can put the SwipeyTabs and ViewPager in red position like in the image, and in the green areas, you have to just adjust them as your needs.
I found these links which may help you. Good luck with that.
Swipey tabs sample
ViewPager meets Swipey Tabs

Disclaimer: I misread your post. Separating the ViewPager from the PagerTabStrip may not work or may need another approach. I'll leave the answer here in case it may help anyway.
You can achieve that by embedding the ViewPager in a separate fragment and placing another independent fragment beneath, which is not controlled by the ViewPager.
Basically, your main activity consists of two fragments: one that contains the ViewPager (which contains more fragments), another one that contains your fixed view.
To do it properly, this needs support for nested fragments, which is only available on Android 4.2 or otherwise in the latest support library (revision 11).
Be aware when instantiating your adapter for the ViewPager, you need to use the FragmentManager returned by getChildFragmentManager().

how to create a slide layout

in my application I would create a new layout, like the standard Android where you see the clock, battery, etc. That Is, it opens with the slide of the finger on the screen. How do I proceed?

You need to use a ViewPager
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/myfivepanelpager"
android:background="#234567"/>
See: http://developer.android.com/reference/android/support/v4/view/ViewPager.html
You can also do a ViewPager solution as Fragments. This is the way to go.
