scroll view can only contain only one child view.so you have to put the views into a relative layout or linear layout or something else and then put this relative layout in scroll view.

I want to create a list of image buttons and i added 3 of them but only two are visible and i want to make them scrollable. I tried using ScrollView but it still doesnt work. I also tried replacing RelativeLayout in the first line with ScrollView but the app started to crash.
Here's the xml file:
<RelativeLayout 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:background="#drawable/back"
tools:context=".home">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/download"
android:layout_gravity="center_horizontal"
/>
</RelativeLayout>

Make the width and height of first scroll view as wrap content .If it doesn't work then
Make only a single scroll view.Then make a Linear layout as its child and in linear layout having vertical orientation add your 3 image buttons.
I have this simple activity in my android app but I don't know how to place my button so it appears at the same position on various screen sizes.
I want the button to always be placed at the bottom of the screen. The screenshot shown is from a phone screen. When displayed on a larger screen the button is higher up.
How can I fix this?
Thanks
See this screenshot
You can use RelativeLayout with this parameter (android:layout_alignParentBottom="true")
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Click Me!"/>
</RelativeLayout>
You should use a RelativeLayout
If you have a RelativeLayout that fills the whole screen you should be able to use android:layout_alignParentBottom to move the button to the bottom of the screen.
If your button at the bottom doesn't show then probably the layout above it takes all the space. In this case you can put the button first in your layout file and position the rest of the layout above the views with android:layout_above.
Have a look a RelativeLayout. Use this ViewGroup and add a Button inside it with alignParentBottom
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
<Button
android:id="#+id/button_id"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:alignParentBottom="true"
android:text="HORAIRE"
android:layout_margins="<your_margin_in_dp>" />
</RelativeLayout>
Make footerButton.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/footer"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:text="HORAIRE"
android:textColor="#ffffff"
android:textSize="20sp" />
</RelativeLayout>
And add it in all your layout file like below line:
Android Activity_Layout
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Footer aligned to bottom -->
<include layout="#layout/footer" />
<!-- Content above footer -->
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#id/footer"
android:layout_below="#id/header"
android:gravity="center">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Content goes here"
android:textColor="#FFFFFF"
android:textSize="20sp" />
</RelativeLayout>
</RelativeLayout>
Hope it will solve your problem
This is what I ended up doing. Thanks to everyone who posted, it helped me get in the right direction!

I have 2 fragments, the first had the second inside it. This is the first:
<?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"
android:background="#drawable/gradient_details_bg"
android:orientation="vertical" >
<TextView
android:id="#+id/fragmentDetailTitle"
style="#style/textTitleDetailStyle" />
<LinearLayout
android:id="#+id/detailSubObjectFrame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:gravity="center"
android:orientation="vertical" >
</LinearLayout>
<Button
android:id="#+id/fragmentDetailButtonGo"
style="#style/goButtonStyle" />
</RelativeLayout>
And inside the layout detailSubObjectFrame I had others fragments. In this specific case:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/sub_take_error_Layout"
android:layout_width="wrap_content"
android:layout_height="match_parent"
>
<LinearLayout
android:id="#+id/numberErrorLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:gravity="center"
android:orientation="horizontal" >
<com.mypackage.NumberPickerCustom
android:id="#+id/numberPickerCustomRandom"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
max="100"
min="1"
value="30" />
<TextView
android:id="#+id/moreText"
style="#style/textOnSubmenu"
android:textSize="20sp"
android:text="#string/moreErrorText" />
</LinearLayout>
<LinearLayout
android:id="#+id/myLayoutTop"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:orientation="horizontal" >
<TextView
android:id="#+id/numberOfQuestion"
style="#style/textOnSubmenu"
android:textSize="20sp"
android:text="#string/numberOfErrorQuestionText" />
<TextView
android:id="#+id/numberOfQuestionValue"
style="#style/textOnSubmenu"
android:textSize="20sp"
android:text="6" />
</LinearLayout>
</RelativeLayout>
I would like that the layout "myLayoutTop", will be placed just below the textview of the first fragment fragmentDetailTitle. (Without moving the other layout from the center).
Like you can see I tried layout_alignParentTop but didn't work.
If needed I could totally change only the layout of the 2nd fragment, the constraint that I have is that numberErrorLayout should stay (like now) on the center of the screen.
I just changed the layout of detailSubObjectFrame in a FrameLayout and sub_take_error_Layout in a LinearLayout. After I used the attribute gravity for numberErrorLayout and myLayoutTop.
I have a problem to layout my view.
I want the "buttonsLayout" to dock at the bottom of the view. That is no problem, but my "buttonsLayout" overlays the "pager". I want that the "pager" stops, where the "buttonsLayout" begins.
I have read so many posts, but nothing helps. What is wrong ?
<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
android:id="#+id/buttonsLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:orientation="horizontal" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Left" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Right" />
</RelativeLayout>
</RelativeLayout>
Add android:layout_above = "#+id/buttonsLayout" to your pager layout. So pager will never overlay buttons.
P.S. I cant see one more closing RelativeLayout tag in your xml...
Here follows the code for my dialog.
<?xml version="1.0" encoding="utf-8"?>

android:id="#+id/source_select_cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#android:string/cancel" />
<Button
android:id="#+id/source_select_ok"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="#android:string/ok" />
</LinearLayout>
</LinearLayout>
When the ExpandableListView is open, it is automatically scrollable; however, the two buttons below it disappear. I have tried enclosing the whole layout within a ScrollView, but then the scrollable behavior of the ExpandableListView is broken (i.e. it gets too small to be actually touched). What I would like to achieve is a dialog that can take up all the screen while allowing the ExpandableListView to be the only scrollable component. Can someone help me with this, please?
Old question, but this can be achieved using a relative layout as the root layout instead of a linear layout
