How to set layout height to one screen height except actionbar and status bar, in scrollview

I have a layout in a scrollview and I add another layout to the end of the first one. Actually I am trying to make a one page design and the rest of the other views will appear after scrolling. I tried to put linearlayout1 and linearlayout2 to another view but it didn't work. Also I set scrollview android:fillViewport="true" but it made the scrollview in screen size.
I've added an image of what I want, but it could also be one view, I mean lin1 and lin2 together.
I can set width and height for one phone but I want to do this for each screen. For example like yahoo weather app. They have done one layout for first view and start another view from the end of screen. I tried so many things but I couldn't imagine how to put layouts. Could you help me?
Thanks for your help
Here is what I want
Here is I tried:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scroller"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:id="#+id/linearlayout1"
android:background="#android:color/holo_purple"
android:layout_width="match_parent"
android:layout_height="350dp" >
<TextView
android:text="LinearLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:id="#+id/linearlayout2"
android:background="#android:color/holo_blue_bright"
android:layout_width="match_parent"
android:layout_height="250dp"
android:orientation="vertical">
<TextView
android:text="LinearLayout2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:background="#android:color/holo_green_light"
android:layout_width="match_parent"
android:layout_height="350dp">
<TextView
android:text="LnearLayout3"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
</LinearLayout>
</ScrollView>
But unfortunately I couldn't configure this for each screen size.
enter image description here

Just try this.
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/action_bar"

Instead of hardcoding the height as in:
android:layout_height="250dp"
Set android:layout_height="0dp" and use
android:layout_weight="25"
And also in the other layout use weight. Weight works like this, if you have 3 components in your container, set the weights to let's say 1, 2 and 3 => they will take in that order 1/6, 2/6 and 3/6 of the container. 6 being the sum of 1,2,3. So here instead of using heights as 350 and 250, you can set them to 0 and use weights 2.5 and 3.5 or 25 and 35.

Android - How do I make the button taller in a linear layout?

I have a linear layout inside a relative layout, and I want to make the buttons 'taller' to fit the height of the linear layout.
I tried adding padding, as you can see in the screenshot, the layout is 'taller' but the buttons are not. I tried 'fill_parent', 'match_parent' but it didn't make a difference. How do I make the buttons expand in height?
<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"
android:id="#+id/timerLayout">
<Chronometer
android:id="#+id/chronometer1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="48dp"
android:text="#string/chronometer"
android:textSize="50sp" />
<LinearLayout
android:id="#+id/buttonLayout"
android:orientation="horizontal"
android:paddingLeft="4.0dp"
android:paddingTop="50.0dp"
android:paddingRight="4.0dp"
android:paddingBottom="4.0dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/btnReset"
android:layout_width="0.0dp"
android:layout_height="fill_parent"
android:drawableLeft="#drawable/ic_restore_white_24dp"
android:drawableStart="#drawable/ic_restore_white_24dp"
android:text="#string/pause_btn"
android:layout_weight="1.5" />
<Button
android:id="#+id/btnStart"
android:layout_width="0.0dp"
android:layout_height="fill_parent"
android:text="#string/start_btn"
android:drawableLeft="#android:drawable/ic_media_play"
android:drawableStart="#android:drawable/ic_media_play"
android:layout_weight="1.5" />
<Button
android:id="#+id/btnSave"
android:layout_width="0.0dp"
android:layout_height="fill_parent"
android:text="#string/save_btn"
android:drawableLeft="#drawable/ic_save_white_24dp"
android:drawableStart="#drawable/ic_save_white_24dp"
android:layout_weight="1.0" />
</LinearLayout>

The extra space you are seeing is from the padding values in your linear layout, and your buttons are already filling the parent linear layout. But your linear layout has specified the following.
android:layout_height="wrap_content"
If you want to see buttons with a larger height, change the height value for your linear layout to something else like:
android:layout_height="300dp"

your linearlayout says height:wrap_content
so the child elements will takeup only as much space as specified.
Try giving either minHeight for linearlayout or simply remove linearlayout and in your buttons specifiy "alignparentbottom = true".
For left-most button give alignparentStart = true.

Take a look at your xml layout file very closely
<LinearLayout
android:id="#+id/buttonLayout"
android:orientation="horizontal"
android:paddingLeft="4.0dp"
android:paddingTop="50.0dp" //this guy
android:paddingRight="4.0dp"
android:paddingBottom="4.0dp"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
the android:paddingTop is the space on the top of every child in your LinearLayout so if you remove it the buttons will fit.

Android RelativeLayout above Fragment

I am trying to display a RelativeLayout above a Fragment without success.
And here my xml :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#5C5A59"
android:gravity="center_vertical"
android:orientation="horizontal"
android:padding="5dp" >
</RelativeLayout>
<fragment
android:id="#+id/map"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center|bottom"
android:background="#5C5A59"
android:orientation="horizontal"
android:paddingLeft="10dp"
android:paddingRight="10dp" >
<TextView
android:id="#+id/lbl_altitude"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:text="#string/lbl_altitude"
android:textColor="#00FFFF"
android:layout_alignParentBottom="true" />
</RelativeLayout>
</LinearLayout>
Using this code the Fragment takes always the entire size of the screen and my RelativeLayout above isnt display.
Thank you in advance.

Try to use layout_weight property
You can read this guide: Linear Layout

if you are using the Linear layout then you have to set the weight this will set your screen according to the percentage for example if you give weightsum 1 to the parent and then you first give the layout weight 0.2 to your layout ang 0.8 to your fragement its means your layout acquires the 20% screen and other fragement acquire 80%
So i think you want to use the Relative layout as your parent and set first child aligment on the top of parent and set the fragement below to the relative layout.

Custom Button Class not resizing based on layout_weight android

I have a CircularMeter class which is derived from Button. The problem is that it is not resizing even if the weight given is 0.5 (ie. half the vertical screen).
<LinearLayout
android:id="#+id/WidgetDataLayout"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_alignParentTop="true"
android:layout_weight="0.5"
android:orientation="vertical"
android:layout_gravity="center_horizontal">
<com.test.CircularMeter
android:id="#+id/cm1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal" />
</LinearLayout>
Any Ideas ?

You can take help from this example to make your circularmeter fill half of the vertical screen
eg.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:weightSum="1">
<LinearLayout
android:id="#+id/linearLayout"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_gravity="center_horizontal"
android:layout_weight="0.5"
android:background="#123456"
android:orientation="vertical" >
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#123456"
android:text="#string/hello_world" />
</LinearLayout>
</LinearLayout>

There's no layout_weight in CircularMeter.
It's parent LinearLayout has both android:layout_alignParentTop="true" and android:layout_weight="0.5" which is not correct since layout_alignParentTop is a layout attribute for a RelativeLayout parent while android:layout_weightis an attribute for a LinearLayout parent. The layout XML does not show what is the parent layout actually is. android:layout_height="0dp" would make the layout invisible unless there really is a vertical LinearLayout as a parent.
Also note that layout_weight="0.5" won't make the view size half the screen. After doing first pass layout for a linear layout, the weight mechanism just distributes any remaining space in proportion of element weights. By default an element's weight is 0. So if you have just one element with non-zero weight, it will get all remaining space in its linear layout parent.

Adding view to bottom of layout inside a scrollview

So my layout looks basically like this:
<ScrollView>
<RelativeLayout>
<BunchOfViews/>
<ImageView android:layout_alignParentBottom="true"/>
</RelativeLayout>
</ScrollView>
I have the ScrollView so all of the layout always is visible no matter the height of the screen. The problem is that on a very high screen, I still want my ImageView to be at the bottom. However, a child of a ScrollView don't seem to have a defined bottom. The View is placed at the top of the layout. How can I solve this problem in a neat way?

I ran into the same issue. I never could find a very pleasing solution, but here is how I did it. Maybe someone else has a better way, I hate adding layouts that don't do anything.
My hack was to add a dummy linearlayout at the bottom of the scrollview that has fill_parent to take up all the room and force the scrollview to fill the screen. Then add whatever component I want to that linearlayout.
Here is one of my layouts that does this:
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:fillViewport="true" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="15px" >
<!-- bunch of components here -->
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#+id/spinner"
android:layout_marginTop="5px"
android:gravity="center_horizontal|bottom"
android:paddingTop="2px" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingLeft="20px"
android:paddingRight="20px"
android:text="Delete" />
</LinearLayout>
</RelativeLayout>
</ScrollView>

I had the same issue and found this page:
http://www.curious-creature.org/2010/08/15/scrollviews-handy-trick/
Basically, you set the ScrollView's android:fillViewport to true, which will allow the child view to expand to the same height as the ScrollView itself, filling out the space. You then just need to have one of the child controls' layout_height set to fill_parent and layout_weight to 1, causing that control to "spring" to fill the empty space.
Note that if the contents of the ScrollView are already tall enough to fill the ScrollView, the android:fillViewport has no effect, so the setting only kicks in when needed.
My final XML looks like similar to this:
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content">
<LinearLayout
android:layout_height="fill_parent"
android:layout_weight="1">
<!-- this expands to fill the empty space if needed -->
</LinearLayout>
<!-- this sits at the bottom of the ScrollView,
getting pushed out of view if the ScrollView's
content is tall enough -->
<ImageView
android:layout_height="wrap_content"
android:src="#drawable/footer_image">
</ImageView>
</LinearLayout>
</ScrollView>

it seems that the linearlayout isn't necessary, all that is important is the fillViewPort.
you could just use
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottomParent="true">
now that you have specified the relativelayout to be at least the size of the screen.

its work for me perfectly android:fillViewport="true"

Joel Malone's answer Adding view to bottom of layout inside a scrollview does that trick. My solution is almost the same, except that I use Space widget to do the work of filling the rest height inside the parent layout. Like this:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
>
<LinearLayout
android:orientation="vertical"
android:layout_height="wrap_content"
>
<android.support.v4.widget.Space
android:layout_height="match_parent"
android:layout_weight="1"
/>
<ImageView
android:layout_height="wrap_content"
android:src="#drawable/footer_image"
/>
</LinearLayout>
</ScrollView>
Attention:
fill_parent in the other answers is noted as deprecated for a long time;
Compare to an empty LinearLayout to fill the rest of parent layout, I think Space is much more appropriate(it's designed to do that job.)
Finally, don't forget that important attribute at the beginning of ScrollView: android:fillViewport="true". They together make this trick.

just put this attribute android:fillViewport="true" to your ScrolView
and you will got what you need

On your view that you want to be at the bottom use android:gravity="bottom"

From: http://code.google.com/p/k9mail/source/browse/k9mail/trunk/res/layout/account_setup_basics.xml?r=1314
This should help you:
<RelativeLayout
android:layout_marginTop="-45dip"
android:padding="0dip"
android:layout_alignParentBottom="true"
android:gravity="bottom|right"
android:background="#android:drawable/bottom_bar"
android:layout_height="fill_parent"
android:layout_width="fill_parent">
<Button
android:id="#+id/manual_setup"
android:text="#string/account_setup_basics_manual_setup_action"
android:minWidth="#dimen/button_minWidth"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:layout_marginBottom="-4dip"
android:layout_alignParentLeft="true"
android:layout_centerVertical="false"
/>
<Button
android:id="#+id/next"
android:text="#string/next_action"
android:minWidth="#dimen/button_minWidth"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:drawableRight="#drawable/button_indicator_next"
android:layout_marginBottom="-4dip"
android:layout_alignParentRight="true"
android:layout_centerVertical="false"
/>
</RelativeLayout>

ScrollView view = new ScrollView( this );
ScrollView.LayoutParams lps = new FrameLayout.LayoutParams( FILL_PARENT, FILL_PARENT, Gravity.CENTER );
LinearLayout layout = new LinearLayout( this );
// what ever you want in the Layout
view.addView( layout, lps );

I tried alot to align the Scroll View to bottom of the screen but thats not possible according to this link.
https://newbedev.com/how-do-i-align-views-at-the-bottom-of-the-screen
The way i found was to create a view with 1dp height and aa id (lets say android:id="#+id/bottomView") at the bottom of your XML page.
now just add these attributes to your scroll view..
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical"
android:fillViewport="true"
android:layout_alignBottom="#+id/bottomView"
>

Here is how you can use a ConstraintLayout to align the image view at the bottom:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/content_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/text_view"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:text="Text 1"
app:layout_constraintBottom_toTopOf="#+id/space_view"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="parent" />
<Space
android:id="#+id/space_view"
android:layout_width="match_parent"
android:layout_height="0dp"
app:layout_constraintBottom_toTopOf="#+id/image_view"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/text_view" />
<ImageView
android:id="#+id/image_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="..."
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/space_view" />
</androidx.constraintlayout.widget.ConstraintLayout>
</ScrollView>
