How to stick a view at the bottom of the screen so the above part is movable?

My layout consists of a ScrollView which holds everything. At some point I need to show a View at the bottom of the screen on top (above) of ScrollView (so ScrollView goes behind the View) so I could scroll the screen up and down while this View still be sticked to a device's screen bottom. Please advice guys how to do such a layout. Thank you.

If you want the scrollview to go behind the view, this can be done like this:
(partial code copy from this SO question)
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/RelativeLayout1">
<ScrollView android:id="#+id/scrollView"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</ScrollView>
<View android:id="#+id/bottomView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:visibility="gone">>
</View>
</RelativeLayout>
The scrollview will now expand beyond the View element.

You could create two fragments and use the weight attribute to distribute the space. The fragment at the top would host you root scrolView and the fragment at the bottom would have the View.

Okay two options, first one:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<View
android:id="#+id/myView"
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_alignParentBottom="true" />
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#id/myView" />
</RelativeLayout>
This way your ScrollView will always be above of your View. But it seems like you want the ScrollView to fill the whole screen while the View "hides" some of the items of your SV. So check this code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
<View
android:id="#+id/myView"
android:layout_width="fill_parent"
android:layout_height="1dp"
android:layout_alignParentBottom="true" />
</RelativeLayout>

Android ScrollView and buttons at bottom of the screen

I want to implement this: A ScrollView that contains many elements (ImageViews, TextViews, EditTexts etc) and then after the ScrollView some buttons (which are custom ImageViews) that appear always exactly at the bottom of the screen.
If I use the android:fillViewport="true" attribute, then if the elements of the ScrollView are too big to fit in the screen size the buttons get invisible . If I use the android:Weight=1 attribute then the ScrollView gets only 50% of the Screen when the screen is big and it can fit (I want the buttons to take a small percentage, about 10%). If I set the android:Weight to bigger values then the buttons appear very small.
Please help! Maybe it is something simple that I overlooked but I’ve been banging my head for hours!

Just created and tested it. Looks like you want.
<?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="match_parent">
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
android:layout_alignParentBottom="true">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Custom Button1"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Custom Button2"/>
</LinearLayout>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/buttons">
<!--Scrollable content here-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="test text"
android:textSize="40dp"/>
</LinearLayout>
</ScrollView>
</RelativeLayout>

</LinearLayout>
</ScrollView>
<RelativeLayout

android:text="Go next page"
android:layout_alignParentRight="true" />
</RelativeLayout>
</LinearLayout>

This worked for me. Give the scroll view a weight of 1. Put all the other widgets following the scroll view in a layout. The scroll view will grow enough to not block the rest.
Widgets in scroll view and rest at bottom

scrollview cannot fit the screen because you put it on a linear layout, so linear layout fit in the screen,
just try to make scrollview as root elemen on xml layout
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<!-- Here you can put some XML stuff and BOOM! your screen fit to scrollview -->
</LinearLayout>
</ScrollView>

If you do not want to use RelativeLayout, it is better to use LinearLayout. This method is better in my opinion.
Just set the layout_weight to one

no gravity for scrollview. how to make content inside scrollview as center

I want the content inside the scrollView as center.
<ScrollView
android:id="#+id/scroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay"
android:layout_gravity="center" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check"
android:gravity="center_vertical|center_horizontal"/>
</ScrollView>
Note: there is no android:gravity attribute for scrollvew.
any sol:-

I had the same issue and finally figured it out. This is for a vertical ScrollView.
Put your ScrollView inside a RelativeLayout and center it in the RelativeLayout. In order for this to work, your ScrollView should have
android:layout_height="wrap_content"
This is how the final code should look like:
<?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">
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="b1"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="b2"/>
<Button
android:id="#+id/button3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="b3"/>
</LinearLayout>
</ScrollView>
</RelativeLayout>

How about this?
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center"
android:gravity="center">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check"
android:gravity="center_vertical|center_horizontal"/>
</LinearLayout>
</ScrollView>

I think a more elegant solution would be to use the ScrollView's android:fillViewport property. A ScrollView is a little different in how it treats it's content view (can only have one), even if you set match_parent (fill_parent) to the ScrollView it won't give that much spacing to it's content view, instead the default behavior is for the ScrollView to wrap the content regardless of what you specify for that view. What android:fillViewport does is tell the ScrollViewto stretch its content to fill the viewport (http://developer.android.com/reference/android/widget/ScrollView.html#attr_android:fillViewport). So in this case, your LinearLayout would be stretched to match the viewport and if the height goes behind the viewport then it will be scrollable which is exactly what you want!
The accepted answer won't work properly when the content extends beyond the ScrollView because it will still center the content view first causing it to cut off a portion of the view, and the ScrollView centered in another layout works but just doesn't feel right, besides I think it will also result in a lint error (useless parent or something along those lines).
Try something like this:
<ScrollView
android:id="#+id/scroller"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay"
android:fillViewport="true">
<LinearLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check" />
</LinearLayout>
</ScrollView>
Just remember that the reason it is being centered here now is because of the android:gravity on the LinearLayout since the ScrollView will stretch the LinearLayout so keep that in mind depending on what you add to the layout.
Another good read on ScrollView although not about centering but about fillViewport is http://www.curious-creature.org/2010/08/15/scrollviews-handy-trick/

Use this attribute in ScrollView
android:fillViewport="true"
Example
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbarStyle="outsideOverlay"
android:fillViewport="true"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<!--Your Code goes here-->
</RelativeLayout>
</ScrollView>
Make sure to use Single Child in ScrollView just like in above example which is Relativelayout.

For #Patrick_Boss - what stopped the content from cutting of in my application was to change the gravity and layout_gravity to center_horizontal for the LinearLayout.
It worked for me...but not sure if it will work for you.
Modification of #Ghost's answer -
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingTop="12dp"
android:paddingBottom="20dp"
android:scrollbarStyle="outsideOverlay" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_gravity="center_horizontal"
android:gravity="center_horizontal">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="check"
android:gravity="center_vertical|center_horizontal"/>
</LinearLayout>
</ScrollView>

One thing to consider is what NOT to set. Make certain your child controls, especially EditText controls, do not have the RequestFocus property set.
This may be one of the last interpreted properties on the layout and it will override gravity settings on its parents (layout or ScrollView).

using the scroll view inside the ConstraintLayout. It is worked for me
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" />
</ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>
Scroll view height should be wrap_content
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"

Android ListView doesn't expand the whole screen

I've problem similar to the one here: Android ListView doesn't expand the whole screen?
The XML is:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="#+id/ResultLayout">
<ScrollView android:layout_width="fill_parent" android:layout_height="fill_parent">
<ListView android:layout_width="fill_parent" android:id="#+id/ListView"
android:layout_height="fill_parent"></ListView>
</ScrollView>
<LinearLayout android:id="#+id/pagingPanel"
android:gravity="center" android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="horizontal"></LinearLayout>
<Spinner android:layout_width="fill_parent" android:id="#+id/ManSpinner"
android:layout_height="fill_parent" />
</LinearLayout>
In this case, I should have a ScrollView or the PagingPanel LinearLayout will disappear.
Edit
The desired layout is to have all the elements stacked on top of each other. but if the elements exceed the page height, a scroll should be added to the ListView.

If you have a vertical LinearLayout, You can't have multiple fill_parent for layout_height of your LinearLayout elements. What layout you would like to achieve? Uniformly divide screen for all elements?
Another problem is that using ListView in ScrollView is not a good idea also because ListView itself is scrollable.
You should write what layout you would like to achieve with your XML. Also generally is a good practice to write your XML in multiple steps and iterate to woking solution layout by layout.
EDIT: Ok, try something like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/ResultLayout">
<ListView android:id="#+id/ListView"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout android:id="#+id/pagingPanel"
android:gravity="center"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
</LinearLayout>
<Spinner android:id="#+id/ManSpinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</LinearLayout>

ScrollView height 0 even when fill_parent

I have a linearlayout A containing a imageview and scrollview. The scrollview contains a second linearlayout B
The idea is to have a fixed header while the linearLayout B contains multiple views that match exactly the height of the scrollview. See it as a tabview where all tabs are after each other in a scrollview.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/main_view"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000"
android:orientation="vertical">
<ImageView android:id="#+id/logoImg"
android:layout_width="fill_parent"
android:gravity="center"
android:src="#drawable/logo"
android:layout_height="wrap_content"/>
<ScrollView
android:id="#+id/scrollView"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:id="#+id/scrollLinear"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</ScrollView>
</LinearLayout>
I tried to achieve this by calling getHeight on the scrollView and then set this height to each view in the linearLayout B but getHeight always returns 0.
Anyone an idea what's the easiest way to achieve this?

Well, the question is very old, but I'll give it a try :)
Wouldn't it be lack of "fillViewport" in ScrollView?
<ScrollView
android:id="#+id/scrollView"
android:layout_weight="1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
