Using RelativeLayout to make a View take all remaining space

I want to achieve this
I am doing this
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="#+id/upper"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/wallet_dim_foreground_inverse_disabled_holo_dark">
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="80dp"
android:orientation="horizontal"
android:layout_below="#+id/upper"
android:background="#color/blueAccentColor">
</LinearLayout>
</RelativeLayout>

<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:id="#+id/upper"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/lower"
android:background="#color/wallet_dim_foreground_inverse_disabled_holo_dark">
</LinearLayout>
<LinearLayout
android:id="#+id/lower"
android:layout_width="fill_parent"
android:layout_height="80dp"
android:orientation="horizontal"
android:layout_alignParentBottom="true"
android:background="#color/blueAccentColor"></LinearLayout>
</RelativeLayout>

You have to set the first Layout to be above the seconde.
With the code you provided you will have a top layout taking all space, and a bottom layout being below him. If you think about it you can see that it's logic that the result will be different.
If you remove android:layout_below="#+id/upper"and add android:layout_alignParentBottom="true"from the lower one, this Layout will be anchored to the bottom side, whichever the screen size is.
Than adding android:layout_above="#+id/lower" to the top Layout, he will take all space(thanks to android:layout_height="fill_parent") but it will stay above the lower Layout.
Here is the result you want :)

Distribution of objects in an activity

I am performing correction on some screens, and on the screen I'm working now, there was a difficulty.
I have a few fields on screen, and even trying to relate the button with the bottom of the screen, the button is in the center.
And it is a large white part after button. I do not know what I can do to fix it. Note: I created the LinearLayout to try solucinar the problem and positions them.
My Code
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ff000000">
<LinearLayout
android:id="#+id/LinLayoutSpin"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Spinner
android:id="#+id/spinner_TamPet"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:entries="#array/tamPet_array"
android:prompt="#string/tamPet_prompt"
android:layout_marginTop="50dp" />
<EditText
android:id="#+id/char_SobreVoce"
android:inputType="textMultiLine"
android:lines="8"
android:minLines="6"
android:maxLines="10"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:layout_below="#id/spinner_TamPet"
android:background="#drawable/edit_text"/>
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_alignParentBottom="true"
android:gravity="bottom"
android:layout_below="#id/LinLayoutSpin">
<Button
android:id="#+id/btnCadastraCliente"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Sou um DoggieWalker"
android:layout_below="#id/char_SobreVoce"
android:background="#drawable/btn_background" />
</LinearLayout>
</RelativeLayout>
The new print after first comment. The white part is up and the form down.

Set android:fillViewPort = "true" in your ScrollView.
In the second LinerLayout set android:layout_height="wrap_content"
you can optimize your screen layout by removing these LinerLayout, only need one RelativeLayout for this screen

Set layout_gravity to bottom for the relative layout
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
layout_gravity="bottom"
android:background="#ff000000">

Button at Bottom

Im not very good in creating android layouts so I am not able to align the button to the bottom in the MainView.
Picture:
Layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="wrap_content" xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical">
<ListView android:id="#+id/lv_pizza" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_weight="1"></ListView>
<Button android:layout_width="fill_parent" android:id="#+id/bt_add"
android:layout_height="wrap_content" android:text="hinzufügen"></Button>
<RelativeLayout android:layout_width="fill_parent" android:id="#+id/relativeLayout2" android:layout_height="fill_parent">
</RelativeLayout>
</LinearLayout>
Please help

This works for a linear layout, note the layout_weight 1 on the list -- that's what pushes the button to the bottom:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView android:id="#+id/lv_pizza"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" />
<Button android:id="#+id/bt_add"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="hinzufügen" />
</LinearLayout>
This then looks like this in the UI editor:

Hi you can set like this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="#+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="wrap_content" xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical">
<ListView android:id="#+id/lv_pizza" android:layout_width="fill_parent"
android:layout_above="#+id/bt_add" android:layout_height="fill_parent" ></ListView>
<Button android:layout_width="fill_parent" android:id="#+id/bt_add"
android:layout_gravity="bottom" android:layout_height="wrap_content" android:text="hinzufügen"></Button>
</RelativeLayout>

Removing the RelativeLayout will push the button to bottom of the screen...

Use a layout_weight for the components inside the LinearLayout. If the ListView has a weight of 1.0, it should push the button to the bottom. I've done this with a ScrollLayout and it works well, allowing the component inside the scroll layout to actually scroll. You could put your ListView into a ScrollLayout to let it grow beyond the visible size.
Also, the second relativelayout also isn't necessary as it doesn't add anything.

You can set a marginTop in the Button until the bottom or change the layout to relative and set the position.

how to set a button at a fixed location on the bottom of UI?

I want a button to appear at fixed location all the time, in the footer of the UI ؟ ( always, if it has components above it or not )

Please take one Relative layout under your main layout . Set its height and width as fill parent and set its gravity as bottom and put any textview or any button you want in it.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom">
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Bottom Gravity" />
</RelativeLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Without Gravity" />
</LinearLayout>
</FrameLayout>

It depends on the layout you are using.
On a RelativeLayout there is
android:layout_alignParentBottom="true"
On a LinearLayout, place it at the bottom and make sure to set the elements layout_weight properly.
Also, check the property
android:layout_gravity
and notice it's different than
android:gravity

Set android:layout_gravity="bottom". Hope this helps.

Put
android:layout_alignParentBottom="true"
in your relative layout.

if any one have two button you can just make this it orks for me
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="bottom" >
<android.support.v7.widget.AppCompatButton
android:id="#+id/btn_yes"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="12dp"
android:text="Valider"/>
<android.support.v7.widget.AppCompatButton
android:id="#+id/btn_no"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="12dp"
android:text="Annuler"/>
</LinearLayout>
</RelativeLayout>`

Android: How can you align a button at the bottom and listview above?

I want to have a button at the bottom of the listview.
If I use relativeLayout/FrameLayout, it aligns but listView goes down to very botton.
(Behind the button at the bottom)
FrameLayout:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/listview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/btnButton"
android:text="Hello"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</FrameLayout>
</FrameLayout>
RelativeLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/listview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/btnButton"
android:text="Hello"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" />
</RelativeLayout>
</RelativeLayout>
Above two codes only work like the first image. What I want is second image.
Can anybody help?
Thank you.

A FrameLayouts purpose is to overlay things on top of each other. This is not what you want.
In your RelativeLayout example you set the ListViews height and width to MATCH_PARENT this is going to make it take up the same amount of space as its parent, and thus take up all of the space on the page (and covers the button).
Try something like:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ListView
android:layout_width="match_parent"
android:layout_height="0dip"
android:layout_weight="1"/>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0"/>
</LinearLayout>
The layout_weight dictates how the extra space is to be used. The Button does not want to stretch beyond the space it requires, so it has a weight of 0. The ListView wants to take up all of the extra space, so it has a weight of 1.
You could accomplish something similar using a RelativeLayout, but if it is just these two items then I think a LinearLayout is simpler.

<?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:background="#ffffff"
>
<ListView android:id="#+id/ListView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1">
</ListView>
<FrameLayout android:id="#+id/FrameLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button android:id="#+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="button"
android:layout_gravity="center_horizontal">
</Button>
</FrameLayout>
</LinearLayout>
Here is the design you are looking for.
Try it.

I needed two buttons side-by-side at the bottom. I used a horizontal linear layout, but assigning android:layout_height="0dp" and android:layout_weight="0" for the buttons' linear layout didn't work. Assigning android:layout_height="wrap_content" for just the buttons' linear layout did. Here's my working layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="#+id/listView1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<Button
android:id="#+id/new_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="New" />
<Button
android:id="#+id/suggest_button"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Suggest" />
</LinearLayout>
</LinearLayout>

RelativeLayout will ignore its children android:layout_width or android:layout_height attributes, if the children have attributes that properly define their left and right or top and bottom values, respectively.
To achieve the result on the right image, showing the list above the button, your layout should look like this:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#android:id/button1"
android:layout_alignParentTop="true"/>
<Button
android:id="#android:id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="#android:string/ok"/>
</RelativeLayout>
The key is to define android:layout_alignParentTop (defines top value) and android:layout_above (defines bottom value) in your RecyclerView. This way, RelativeLayout will ignore android:layout_height="match_parent", and the RecyclerView will be placed above the Button.
Also, make sure you look into android:layout_alignWithParentIfMissing, if you have a more complex layout and you still need to define these values.

I am using Xamarin Android, and my requirement is exactly the same as William T. Mallard, above, i.e. a ListView with 2 side-by-side buttons under it.
The solution is this answer didn't work in Xamarin Studio however - when I set the height of the ListView to "0dp", the ListView simply disappeared.
My working Xamarin Android code is as follows:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/ListView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_above="#+id/ButtonsLinearLayout" />
<LinearLayout
android:id="#id/ButtonsLinearLayout"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:orientation="horizontal"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/Button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
<Button
android:id="#+id/Button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1" />
</LinearLayout>
</RelativeLayout>
I aligned ButtonsLinearLayout to the bottom of the screen, and set the ListView to be above ButtonsLinearLayout.

#jclova one more thing you can do is use layout-below=#+id/listviewid in relative layout

In your relative layout height of listview is match_parent which is fill_parent(for 2.1 and older) so best solution is if you want to use relative layout then first Declare your button then your list view, make list view position as above your button id, If you want button always at bottom then make it alignParentBottom..
Snippet is
<RelativeLayout
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:id="#+id/rl1"><Button
android:layout_width="MATCH_PARENT"
android:layout_height="WRAP_CONTENT"
/><ListView
android:layout_width="MATCH_PARENT"
android:layout_height="0"
android:layout_above="#id/listview"/></RelativeLayout>
This prevents your list view taking whole place and make your button appear..

This will be the best and the most simple solution to the problem. Just add android:layout_above="#id/nameOfId" in the layout that you want to move above with respect to that layout.
<?xml version="1.0" encoding="utf-8"?>
