XML Layout overlap

I am trying to create a certain layout, that consists of 2 parts a scrollview and a "footer" at the bottom, but always on top of the scrollview. Everything inside the scrollview must be visible (by scrolling).
This is my current code:
<?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"
>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/banner" />
<TextView
android:layout_width="fill_parent"
android:paddingTop="1dp"
android:layout_height="3px"
android:background="#DADADA" />
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:text="Start Connecting" />
<Button
android:id="#+id/button01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/button1"
android:layout_alignParentLeft="true"
android:text="First use" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:text="Welcome to ADB Wireless!"
android:textSize="25sp" />
</RelativeLayout>
</LinearLayout>
But it gives an overlap on small screens & landscape mode. I would only like to have the 2 buttons to be inside the 'footer'. Thank you!

<?xml version="1.0" encoding="utf-8"?>

Android: how to align views vertically and horizontally

I'm wondering how I can align the buttons as the following: Button1 and Button2-2 are supposed to align horizontally, Button2-1 and Button2-2 should align vertically.
[Button2-1]
[other views] [Button1] [Button2-2]
Here is my code but it doesn't work:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ButtonGroups"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:id="#+id/Button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical" >
<Button
android:id="#+id/Button2-1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<Button
android:id="#+id/Button2-2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
EDITED:
To be more clear, I posted more code here and hopefully it could explain my needs better:
What I want is to align the text view horizontally with the image buttons while vertically with the seekbar above it.
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ButtonGroups"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal" >
<ImageButton
android:id="#+id/Button00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/background00"
android:gravity="bottom"
android:scaleType="center"
android:src="#drawable/button00" />
<ImageButton android:id="#+id/Button11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/button11"
android:scaleType="center"
android:gravity="bottom"
android:background="#drawable/background11"
/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="bottom"
android:orientation="vertical" >
<SeekBar
android:id="#+id/SeekBar1"
style="#style/MySeekBar1"
android:layout_width="60dp"
android:layout_height="35dp"
android:layout_marginBottom="20dp"
/>
<TextView
android:id="#+id/MyText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="bottom"
android:background="#drawable/MyTextImg"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>

Use RelativeLayout. Stacking LinearLayouts is usually not the way to go!
https://developer.android.com/reference/android/widget/RelativeLayout.html
https://developer.android.com/guide/topics/ui/layout/relative.html

Try changing the gravity attribute of the first button (Button 1) to bottom.

As someone suggested, use a RelativeLayout to design this type of pattern! Here's an example for your situation:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ButtonGroups"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/Button2-2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/Button1"
android:layout_alignBottom="#+id/Button1"
android:layout_toRightOf="#+id/Button1"
android:text="button 2-2" />
<Button
android:id="#+id/Button2-1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/Button2-2"
android:layout_alignLeft="#+id/Button2-2"
android:text="button 2-1" />
<Button
android:id="#+id/Button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="54dp"
android:text="button 1" />
</RelativeLayout>
I hope this get you started!

Try the code below:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:stretchColumns="*">
<TableRow >
<TextView />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2-1" />
</TableRow>
<TableRow >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button1" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2-2" />
</TableRow>
</TableLayout>
The trick is to use a blank text view for the empty space in the first row. Let me know if this helps you. :)

Position ListView Below Buttons

I have a ListView that is appearing behind two buttons. I'd like the ListView to fill the area below the buttons. I've tried the solutions in this link:
Android Layout with ListView and Buttons and Listview with button below not working properly . However, it is not working. Can you tell me how to keep theListView below the buttons?
Here is my code:
<?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"
android:layout_weight="1.0"
>
<ListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_below="#id/layoutButtons"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:weightSum=".50" />
<LinearLayout
android:id="#+id/layoutButtons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1.0" >
<Button
android:id="#+id/btnLogout"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".70"
android:text="left" />
<Button
android:id="#+id/btnMessage"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".30"
android:text="right" />
</LinearLayout>
</RelativeLayout>

Try the following:
<?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="fill_parent"
android:orientation="vertical"
>
<LinearLayout
android:id="#+id/layoutButtons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<Button
android:id="#+id/btnLogout"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".70"
android:text="left" />
<Button
android:id="#+id/btnMessage"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".30"
android:text="right" />
</LinearLayout>
<ListView
android:id="#+id/listview"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
Hope this helps.

You can add the buttons in the header of the listview:
Create a layout with the buttons
listview_header.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/layoutButtons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1.0" >
<Button
android:id="#+id/btnLogout"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".70"
android:text="left" />
<Button
android:id="#+id/btnMessage"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".30"
android:text="right" />
</LinearLayout>
Declare views:
private ListView listView;
private ViewGroup mListHeaderView;
onCreateView()
mListHeaderView = (ViewGroup)inflater.inflate(R.layout.listview_header,
listView, false);
onActivityCreated()
listView = this.getListView();
listViewTickets.addHeaderView(mListHeaderView,null,false);

Modified Leoa's answer a bit:
<LinearLayout
android:id="#+id/layoutButtons"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1.0" >
<Button
android:id="#+id/btnLogout"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".70"
android:text="left" />
<Button
android:id="#+id/btnMessage"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight=".30"
android:text="right" />
</LinearLayout>
<ListView
android:id="#android:id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="#id/layoutButtons"
android:weightSum=".50" />
Removed the
android:layout_alignParentTop="true"
from the ListView and changed the id of the ListView to #android:id/list.
Also the ListView must be placed below the LinearLayout with the buttons, else you won't be able to use android:layout_below in the ListView.

Align two-button layout left and right in Android

I want to align two buttons with a linear layout, one on the left, and one on the right, like the next and previous buttons on an image gallery. I tried to align them but it doesn't work.
XML layout code:
<?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="fill_parent"
android:orientation="vertical"
android:background="#android:color/white"
android:gravity="bottom" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"
android:layout_alignParentRight="true" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next" />
</LinearLayout>
</LinearLayout>
Actual output:
Expected output:
How can I fix it?

Use a RelativeLayout. There you can set android:layout_alignParentLeft and android:layout_alignParentRight.
This should work for you:
<?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="fill_parent"
android:orientation="vertical"
android:background="#android:color/white"
android:gravity="bottom" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"
android:layout_alignParentLeft="true" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next"
android:layout_alignParentRight="true"/>
</RelativeLayout>
</LinearLayout>

With Linear Layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"/>
</LinearLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"/>
</LinearLayout>
With Relative Layout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"
android:layout_alignParentLeft="true"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:layout_alignParentRight="true"/>
</RelativeLayout>

Use Relative layout in your LinearLayout;
Also add android:layout_alignParentLeft="true" to "prev" Button
and android:layout_alignParentRight="true" to "next" Button
<?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="fill_parent"
android:background="#android:color/white"
android:gravity="bottom"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true" <---- ADD this prop
android:text="prev" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true" <----- ADD this prop
android:text="next" />
</RelativeLayout>
</LinearLayout>

I guess, the simplest solution is to use View in your inner LinearLayout.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"/>
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next"/>
</LinearLayout>

Something like 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" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="right" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Button" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/button1"
android:orientation="vertical" >
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
The idea is, to create a RelativeLayout as container and put first Button and then stick it to the right of parent view. After that, add Another button inside LinearLayout and set this LinearLayout into the left of first Button.
Here's the result.

ur layout xml should be as shown below
<?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"
android:gravity="bottom"
android:background="#fff">
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000"
android:layout_gravity="bottom" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Pre" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Next" />
</RelativeLayout>
</RelativeLayout>

Use a RelativeLayout instead of a LinearLayout you can add the tags android:layout_alignParentRight="true" and android:layout_alignParentLeft="true" on each button.

You can use RelativeLayout like this:
<?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="fill_parent"
android:background="#android:color/white"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black"
android:gravity="bottom"
android:orientation="horizontal" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="prev" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="next" />
</RelativeLayout>
</LinearLayout>
(I used grey instead of white for the screenshot)

Use a FrameLayout and add the layout_gravity attribute in each of the buttons

Do something like this it will surely help you out
<?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"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Linear"
android:textSize="35dp"
android:layout_margin="90dp"
/>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Relative"
/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="200dp"
android:text="Constraint" />
</LinearLayout>
</LinearLayout>

Use margin_Start and End to seprate the buttons in the layout
<?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:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="-:Linear Layout:-"
android:textSize="35sp"
android:layout_gravity="center"
android:layout_marginTop="250dp"
tools:ignore="HardcodedText"/>
<LinearLayout
android:id="#+id/linear2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_marginTop="90dp">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Relative"
tools:ignore="ButtonStyle,HardcodedText"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="200dp"
android:text="Constraint"
tools:ignore="ButtonStyle"
/>
</LinearLayout>
</LinearLayout>

For Better Performance:
Best to put two views left and right and one view between in linear layout rather than relative layout. Use the below code it will also remove the nesting of views .... It will be good in performance perpective :
<?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="wrap_content"
android:gravity="center_vertical">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="prev" />
<TextView android:text="Hi its working"
android:layout_width="0dp"
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:text="next" />
</LinearLayout>

Making linearlayouts scrollable in android

I am making an android application that needs to use a scrollable layout that contains a couple of linearlayouts, a textview and a listview. How can i make this happen??? Please help and thanks SO much in advance! This is the xml code that i am using so far:

Make your main layout as scroll layout inside that put the linear layout.
Keep in mind Scroll layout can hold only one type of item...
Once you do this, the whole layout is scroll able up and down or left and right as per your XML config.
