How to make a horizontal recyclerview appear bottom of the screen?

I wanna to build the layout like the diagram below. When I click the button a horizontal recyclerView slide up and appear at the bottom of the screen under the LinearLayout which contain the button.
I looking to use bottom sheet.When the bottom sheet with recyclerView appear,but it cover the whole LinearLayout which contain the button.Here is my layout xml:
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<LinearLayout
android:id="#+id/bottomBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#color/white"
android:orientation="horizontal"
android:paddingBottom="5dp"
android:paddingTop="5dp">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#null"
android:text:"Button"/>
</LinearLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/horizontalRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_anchor="#id/bottomBar"
android:animateLayoutChanges="false"
android:scrollbars="horizontal"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"/>
</android.support.design.widget.CoordinatorLayout>
So my question is,how can I make the horizontal recyclerView slide up and appear from the bottom of the screen? Am I going the right direction? Or have a better approach to achieve this?
Thanks in advance.

You can achieve that in simple steps:
First keep your linear Layout orientation vertical by adding this.
android:orientation="vertical"
And then add recycler view below button inside linearLayout.Whenever you have to hide recyclerview keep the visibility of recyclerview as "gone" and to show keep visibility as "visible" like this.
Initially keep your recycler hidden in xml and by adding this line in xml
android:visibility="gone"
Thrn whenver button is clciked make your recycler appear in java like this
yourRecycler.setVisibility(View.VISIBLE);
Finally your xml should look like this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
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:fitsSystemWindows="true">
<LinearLayout
android:id="#+id/bottomBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/white"
android:orientation="vertical"
android:paddingBottom="5dp"
android:layout_alignParentBottom="true"
android:paddingTop="5dp">
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#null"
android:text="button"/>
<android.support.v7.widget.RecyclerView
android:id="#+id/horizontalRecyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="gone"
android:animateLayoutChanges="false"
android:scrollbars="horizontal"
/>

try below steps,
First, define XML like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layout_root"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="3"
>
<Button
android:id="#+id/tv1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textColor="#FFF"
android:text="hello"
android:textStyle="bold"
android:layout_weight="1"
/>
<RecycleView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="2"
android:visibility="gone"
>
</RecycleView>
</LinearLayout>
Second, initially set RecycleView visibility gone.
Third, on click of Button set RecycleView visibility visible in run time.

You can use this library.

How to add FrameLayout inside LinearLayout

Hi i am new for android in my app i am adding Frame-layout inside LinearLayout but Frame-Layout and it's inside fields are not adding
my code is below please help me some one
main.xml:-
<?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">
<FrameLayout
android:id="#+id/frame"
android:layout_width="match_parent'"
android:layout_height="wrap_content">
<TextView
android:layout_width="0dp"
android:layout_weight ="1"
android:layout_height="wrap_content"
android:background="#android:color/holo_red_dark"
android:text="something" />
<Button
android:layout_width="30dp"
android:layout_height="30dp"
android:background="#android:color/holo_red_light"/>
</FrameLayout>
<ListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/frame" />
</LinearLayout>

I think you misunderstand the purpose of FrameLayout.
http://developer.android.com/reference/android/widget/FrameLayout.html
FrameLayout is designed to block out an area on the screen to display
a single item. Generally, FrameLayout should be used to hold a single
child view, because it can be difficult to organize child views in a
way that's scalable to different screen sizes without the children
overlapping each other.
You are trying to put two items inside of it. I would suggest removing the FrameLayout. You have no need of it.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button" />
</FrameLayout>
</LinearLayout>
This works for displaying a single button, but there's no point in having it there.

Cam any one please help for solving this issue:)

It is not recommended to scroll inside scroll in android. Recycler view is itself a scroll. Seems you want a scrollable portion above a list "layout_top_balance". Add this view as header of recycler view and remove scrollview. This will solve your problem.

You can use this recycle view lib if you want to add header

Button spanning 2 fragments (xml layout)

Can't figure out how to set this up in XML...
Trying to get a button to lay over 2 fragments that sit behind it.
What I want:
What I have:
My code:
<?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="horizontal"

>
<Button
android:id="#+id/luckBtn"
android:layout_gravity="bottom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

<fragment

android:id="#+id/firstWord"
android:layout_weight="1"
android:layout_width="0dp"

android:id="#+id/lastWord"

You can do this with a RelativeLayout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

android:name="com.wizardknight.visionaryvulgarity.FirstWord"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
<fragment
android:id="#+id/lastWord"
android:name="com.wizardknight.visionaryvulgarity.LastWord"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1" />
</LinearLayout>
<Button
android:id="#+id/luckBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_gravity="bottom"
android:text="#string/feel_lucky"
android:textColor="#ffffff" />
</RelativeLayout>
Explanation:
The difference between RelativeLayout and LinearLayout is simple. LinearLayouts order their child views, like the name already says, linearly. That means, that the child will order themselves, depending on the orientation of the LinearLayout, vertically or horizontally to each other. The child view of a RelativeLayout on the other hand order themselves relative to the parent view or to other views. In this layout I just changed the parent layout to RelativeLayout and wrapped your fragments in a LinearLayout, so it they can use the layout_weight attribute. Then I set this to the button:
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
This aligns the button to the bottom and centers them horizontally. Now, since it does this relative to the top level layout, it overlaps the fragment. 

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.
