Android XML: How to place widget below included layout

I am trying to place a chart widget (com.android.AnyChartView, #+id/piechart) from the AnyChart library (https://github.com/AnyChart/AnyChart-Android) below an included layout (#layout/content_main) that contains a TabHost. I tried giving the include an id and setting the layout_below property of the chart widget, but that has not worked. The app graph fills the entire screen, covering the Tab view.
Below is my code:
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"/>
<include layout="#layout/content_main"
/>
<com.anychart.AnyChartView
android:id="#+id/piechart"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" />
</FrameLayout>
</LinearLayout>
</TabHost>
</androidx.constraintlayout.widget.ConstraintLayout>
Below is a screenshot of the app:

You need to remove your pie chart from main_activity and put it under content_main like this:

</androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>
I have added the scrollview but you can remove it if it's not in your requirements.

There are a number of possible solutions
Solution 1
On the include tag indicate android:layout_width="match_parent" and android_height="wrap_content"
<include layout="#layout/content_main"
android:layout_width="match_parent"
android_height="wrap_content"
/>
Solution 2
Using LinearLayout as the parent ViewGroup provide android:layout_weight="1" and android:layout_height="0dp" on the include tag, this will allow the content_main.xml to occupy the remaining space and yet fit on the screen.
<include layout="#layout/content_main"
android:layout_width="match_parent"
android_height="0dp"
android_layout_weight="1"
/>

Android: Issue with ScollView and ViewPager

I am creating UI like as per below code
View pager with images and then other UI controls.
It is working fine with 2-3 controls, but if UI is out of page with 10 UI controls then scroll view not wokring.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fadeScrollbars="true"
android:fillViewport="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:weightSum="3">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<android.support.v4.view.ViewPager
android:id="#+id/scheduleViewPager"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="2"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/create_account_create_password" />
// Other UI controls
</LinearLayout>
</LinearLayout>
</ScrollView>

Please try this below code ...
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"

Progress bar on centre in relative layout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="?android:attr/actionBarSize"
android:background="#drawable/stalker_background"
android:focusableInTouchMode="true" >
<ProgressBar
android:id="#+id/pb"
android:layout_height="75dp"
android:layout_width="75dp"
android:layout_gravity="center"
android:indeterminate="true"
/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:id="#+id/svProfile"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<android.support.v4.view.ViewPager
android:id="#+id/VPSlider"
android:layout_width="match_parent"
android:layout_height="175dp"
/>
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" />
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>
</LinearLayout>
</ScrollView>
</LinearLayout>
</RelativeLayout>
Progress Bar appears at corner of the screen, how can I align it on centre of the screen. I have relative layout and I'm removing this progress bar after I have some thing to show on screen that's why I need this on top of other controls.

Try this..
Add android:layout_centerInParent="true" to your ProgressBar because you parent layout is RelativeLayout
<ProgressBar
android:id="#+id/pb"
android:layout_height="75dp"
android:layout_width="75dp"
android:layout_gravity="center"
android:indeterminate="true"
android:layout_centerInParent="true"
/>

Try this way,hope this will help you to solve your problem.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="?android:attr/actionBarSize"
android:background="#drawable/stalker_background"
android:focusableInTouchMode="true" >
<ProgressBar
android:id="#+id/pb"
android:layout_height="75dp"
android:layout_width="75dp"
android:layout_centerInParent="true"
android:indeterminate="true"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ScrollView
android:id="#+id/svProfile"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
</LinearLayout>
</RelativeLayout>

How can I put FragmentTabHost Tabs at the bottom of the screen?

I have tried the following code. which aligns the framed layout above the tab widget but it still didn't work
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal" />
<FrameLayout
android:id="#+id/tabFrameLayout"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_alignParentTop="true"
android:layout_above="#android:id/tabs"
/>
</RelativeLayout>
</android.support.v4.app.FragmentTabHost>
edit
i am using FragmentTabHost. maybe that could be why it's not changing position

The solution which finally worked for is the following:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/realtabcontent"
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1" />
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="0" />
</android.support.v4.app.FragmentTabHost>
</LinearLayout>

Try this
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:padding="5dp"
android:layout_weight="1"/>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="0"
android:visibility="visible"
/>
</LinearLayout>

Maybe like this:
<android.support.v4.app.FragmentTabHost
android:id="#android:id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TabWidget
android:id="#android:id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal" />
</RelativeLayout>
<FrameLayout
android:id="#+id/tabFrameLayout"
android:layout_width="match_parent"
android:layout_height="0dp" />
</LinearLayout>
</android.support.v4.app.FragmentTabHost>

Display tabs at the bottom in Android

First of all sorry! I really have tried to use StackOverFlow to find the answer to this. I've seen an answer here -Android: Tabs at the BOTTOM which other people are understanding, but I cannot get my head around the solution.
My cut down XML code is this
<?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:orientation="vertical" >
<TabHost
android:id="#+id/tabhost"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="bottom"
android:orientation="vertical"
android:padding="5dp" >
<FrameLayout
android:id="#android:id/tabcontent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" >
<LinearLayout
android:id="#+id/tab1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</FrameLayout>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="-5px"
android:layout_weight="0"
android:background="#ffff0000" >
</TabWidget>
</LinearLayout>
<LinearLayout
android:id="#+id/tab2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
<LinearLayout
android:id="#+id/tab3"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
</LinearLayout>
</FrameLayout>
</LinearLayout>
</TabHost>
How can i get the selection of tabs to be displayed at the bottom? Many thanks

for this you will have to use RelativeLayout instead of LinearLayout than you can use android:layout_alignParentBottom="true" property inside TabWidget
Change
<LinearLayout
android:id="#+id/tab1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
</FrameLayout>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="-5px"
android:layout_weight="0"
android:background="#ffff0000" >
</TabWidget>
</LinearLayout>
To
<RelativeLayout
android:id="#+id/tab1"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<FrameLayout
android:layout_alignParentTop="true"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</FrameLayout>
<TabWidget
android:id="#android:id/tabs"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginBottom="-5px"
android:layout_weight="0"
android:layout_alignParentBottom="true"
android:background="#ffff0000" >
</TabWidget>
</RelativeLayout>
