I am working on a app in which layout structure is as follows -
Activity A - This activity is a Tab Layout Activity which uses viewpager for tabs and code is given below.
<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/main_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_marginTop="24dp"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tabMode="scrollable" />
</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_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
The fragment that is added to the viewpager has a common layout for all tabs and code is given below.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="8dp"
android:paddingBottom="8dp"
android:background="#color/background_app"
tools:context="com.peacecorps.pcsa.safety_tools.SafetyPlanActivity">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textColor="#color/primary_text_default_material_dark"
android:textSize="20sp"
android:textStyle="bold"
android:text="#string/safety_plan_subtitle"/>
<android.support.v4.view.ViewPager
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/safety_plan_pager"
android:layout_marginTop="20dp"
android:layout_width="match_parent"
android:layout_height="320dp" />
<Button
android:id="#+id/actionButton"
style="#style/NavigateButton"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="15sp"
android:text="#string/see_action"
android:layout_marginTop="10dp" />
</LinearLayout>
As you can see this fragment again contains a viewpager.This viewpager will always be populated by a fragment below.
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<include android:id="#+id/text_to_show"
layout="#layout/textview"/>
</ScrollView>
where textview is
<?xml version="1.0" encoding="utf-8"?>
<!--This is the common layout used for TextViews-->
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#color/primary_text_default_material_dark"
android:textSize="#dimen/abc_text_size_medium_material"
android:layout_gravity="center_horizontal"
android:background="#drawable/bg_textview_rounded_rectangle"
android:padding="#dimen/textview_padding"
android:scrollbars="vertical"
android:fadeScrollbars="false"
android:layout_marginBottom="#dimen/activity_vertical_margin"
android:autoLink="web|email"
android:textColorLink="#color/text_color_link"
/>
Here textview contains text of different amount which is set dynamically in java for different tabs.
The problem I am facing is that only part of UI is available in landscape mode and some part is lost which is not scrollable too.Please help me, I am stuck on this for a really long time.
The problem you are facing is because you have 2 scrolling behavior. When the phone is on portrait mode it has a lot of space that 320dp height ViewPager won't be able to occupy all the spaces available, but when the phone is on landscape mode 320dp height ViewPager will occupy the whole screen so the layout will only scroll the second view pager, that means that the whole screen on landscape mode will only have access on the second ViewPager.
Remember that the ones on the bottom are the first to be accessed. That means that a view that is on the bottom have a higher z-index - Code Reference not the actual view.

I've implemented a standard tab layout with 3 fragments with custom tab view as mentioned in this post.
The problem is the titles in the tabs are very long in some languages. For example, "Unsolved cases" in Finnish language is "ratkaisemattomat tapaukset" which causes this:
Custom view implementation
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:tools="http://schemas.android.com/tools"
android:background="#color/colorPrimary">
<TextView
android:id="#+id/text_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#ffffff"
android:textSize="16sp"/>
</FrameLayout>
Tab Layout XML

android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
I understand if this is not recommended by Google in having a large text in tabs but the translated text is too long.
I need a way by which I can dynamically scale the tab height with the length of the text. I cannot give static height in the xml file. Is there any way I can achieve this?
I created a viewpager using a fragment adapter which returns a few fragments
however the layout is not taking into acount the tabs height and results in cut and missing items for lower part of the screen (the fragment layout).
i.e it has a toolbar or a button which suppose to show at the bottom of the layout it will look okay in the layout editing tool which shows only the fragment but once inside the pager it will ignore the height of the tabs keep thinking the layout takes the entire screen resulting in the lower part not showing properly (only the higher part of the button is shown)
How can i make it to take into account the height of the tabs in the activity?
the inflation code:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.fragment_test,container,false);
return view;
}

I created a Scroll View which should allow me to scroll through all the content which is inside Linear Layout (that is a child of Scroll View).
Code looks like this:
<ScrollView 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="pl.oakfusion.delegator.DomesticDelegationSecondFragment">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content">
....
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="25dp"
android:layout_marginTop="25dp"
android:background="#color/textDarkest"
android:text="Save"
android:textColor="#color/textColor"
android:layout_gravity="right" />
</LinearLayout>
Preview looks like this:
But in my app I have this:
I can't scroll down, this is all I can see.
If I allow to rotate I have horizontal view:
which now allows me to scroll but cuts the button entirely. (On the picture is bottom of view) I can pull down fast and I can see that the button is there but it goes up again (this android thing when you can pull slightly further but it scrolls back)
How can I fix this?

try adding this to the scrollView in your xml layout
android:fillViewport="true"
I have experienced the same problem once. I tried adding padding for the ViewGroup inside ScrollView. Then it worked fine. Its a hacky solution and not an ideal one.
For the example mentioned above (by user3212350):
I have added some padding to the LinearLayout inside ScrollView to make the view completely visible. The amount of padding required may differ for various screen sizes.
<ScrollView 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="pl.oakfusion.delegator.DomesticDelegationSecondFragment">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
##android:paddingBottom="50dp"##>
....
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="25dp"
android:layout_marginTop="25dp"
android:background="#color/textDarkest"
android:text="Save"
android:textColor="#color/textColor"
android:layout_gravity="right" />
</LinearLayout>
EDIT: See Using the Master/Detail template in ViewPager Fragments (download link) for full code
I have a toolbar and a recyclerView. When the layout is first inflated the last item of the recyclerView is out of the scroll-able region of the screen and is therefore not visible. After rotating the item appears. It is apparent that the toolbar is pushing the recyclerView outside the boundaries of the screen. If I add padding to the bottom of the recyclerView with the height of the toolbar the issue is resolved BUT only for the initial inflation of the layout. After rotation I am left with a gap on the bottom of the screen. I'm using sdk 23.
A possible workaround would be to programmatically remove the padding after the very first inflation of the layout. I assume I could use:
onCreateView(){ if (onSaveInstanceState != null) removePadding();}
However, I'd rather not have to do a dodgy work-around.
My app is basically exactly the same as the Master/Detail-flow template supplied in Android Studio, except that I use fragments and a single Activity. There is no such issue in the template.
Any ideas?

snippet of ItemListFragment.java
Toolbar toolbar = (Toolbar) root.findViewById(R.id.toolbar);
toolbar.setTitle("List");
I added:
android:layout_gravity="fill_vertical"
android:layout_marginBottom="?attr/actionBarSize"
to item_list.xml. The issue persists. The first time the layout is inflated it shows the bottom element as expected. After rotating to landscape and back to portrait it leaves a margin the size of the actionBar at the bottom of the screen.
This issue does not happen in the Master/Detail-flow template available in Android Studio and the code for item_list.xml, item_list_twopane.xml and activity_item_list are exactly the same as the code used in item_list.xml, land/item_list.xml and fragment_item_list.xml in my project. Yet, as the attached images show, the preview of the AppBar shows the flexible space in the Android template but not my code.
EDIT: When I click on the reference for "?attr/actionBarSize" in the template it navigates to a different line in android SDK's values.xml, which starts with <declare-styleable name="AppCompatTheme">. The same line of code in my app references a different line starting with<declare-styleable name="Theme">.

You must add
android:layout_paddingBottom="?attr/actionBarSize
Instead of
android:layout_marginBottom="?attr/actionBarSize
This works for me

<!-- When I add my own view here and use match_parent, it fills ENTIRE screen, even over the Toolbar. The ViewPager right above does not do this. Why? -->
</android.support.design.widget.CoordinatorLayout>
I am trying to add my own buttons/textviews/etc to my activity_main.xml but I do not know where to add them. The android.support.v4.view.ViewPager uses match_parent although it does not fit the whole screen, it expands across the entire screen besides the Toolbar area at the top. However, whenever I add my own view underneath the android.support.v4.view.ViewPager, lets say RelativeView and set it to match_parent, it expands OVER the Toolbar. This led me to believe that I should put my contents inside the ViewPager tags but that does not work either.
Where should I put my views so that they are not overlapping the Toolbar?
You can wrap your ViewPager in an RelativeLayout and you can add the view child also.
Here is the code snippet which may help you-
<RelativeLayout
