Alight two buttons in the same Horizontal Line

I am trying to make the "Save" and "Attach Pic" buttons align at the top of my xml page but I can't quite get it to work. I got it to the point where the buttons would align just not in the same horizontal line. Oh, and is there any way that I can make both buttons align in the top left and top right corners?
Here is the xml page:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#ffffff" >
<!-- Footer Start -->
<LinearLayout
android:id="#+id/footer"
android:layout_width="fill_parent"
android:layout_height="90dip"
android:layout_alignParentBottom="true"
android:background="#layout/footer_repeat"
android:orientation="horizontal" >
</LinearLayout>
<!-- Footer Ends -->
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dip" >
<!-- Save button -->
<Button
android:id="#+id/btnSavePic"
style="?android:attr/buttonStyleSmall"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="10dip"
android:text="#string/savePic"
android:layout_gravity="top|left"/>
<Button
android:id="#+id/btnAttachPic"
style="?android:attr/buttonStyleSmall"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="10dip"
android:text="#string/attachPic"
android:layout_gravity="top|right"/>
</LinearLayout>
</RelativeLayout>
</ScrollView>

I would suggest using an eclosing LinearLayout:
<LinearLayout
android:id="#+id/linear_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<Button
android:id="#+id/btnSavePic"
android:layout_width="0dip"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="#string/savePic"
/>
<Button
android:id="#+id/btnAttachPic"
android:layout_width="0dip"
android:layout_weight="1"
android:layout_height="wrap_content"
android:text="#string/attachPic"
/>
</LinearLayout>

Try this. Hope it will work.
Change your orientation to horizontal in
So that you can get the buttons in horizontal alignment.
Pls vote if it get works.

how to overlap two images each other

how to add images above the image? this is my screen shot http://imgur.com/Yh4DqnJ which have only 1 image in background now i want to add two imagebutton like this image http://imgur.com/XrLXb0L below is my code which have only background image
below is my code which have background imeage onheader Linearlayout how i add two images on left and right side??
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#drawable/imagelogo2"
android:orientation="horizontal" >
</LinearLayout>
<LinearLayout
android:id="#+id/lytContent"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/txtCopyright"
android:layout_marginTop="10dp"
android:background="#drawable/border2"
android:layout_below="#+id/lytTitlebar"
android:orientation="vertical" >
<ListView
android:id="#+id/listMainMenu"

android:layout_height="wrap_content"
android:listSelector="#drawable/listview_selector"
android:dividerHeight="1dip"
android:fadeScrollbars="true" />
</LinearLayout>
</LinearLayout>

Best way to use overlap images is through frame layout
Try this code
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:src="#drawable/onlymobilepro"
android:scaleType="fitCenter"
android:layout_height="fill_parent"
android:layout_width="fill_parent"/>
<TextView
android:text="This is Frame Layout!!!"
android:textSize="24px"
android:textColor="#cc0000"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:gravity="top"/>
<TextView
android:text="Learn Android Development At onlyMobilePro.com"
android:textSize="24px"
android:textColor="#00dd00"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
android:gravity="center"/>
</FrameLayout>

For overlapping images you should probably use Framelayout,

Space unwanted layout and image

like the title said it there are some "space" before and after an image and i don't want it.
<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="#drawable/fond"
>
<ImageView
android:id="#+id/imageView1"
android:contentDescription="#string/desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/top"
android:layout_gravity="top"
/>
<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="#drawable/fond1"
>
</LinearLayout>
</LinearLayout>
So like you can see i have a first Layout with a background.
The ImageView is just after and should be on the top but it didn't.
The second Layout is to much after the image.
->
first layout
--unwanted space--
image
--unwanted space--
second layout
If anyone know how to delete this "space", thanks.

Use android:adjustViewBounds="true" inside your ImageView. That way your ImageView will be adjusted to the provided image bounds.

Use Relative layout this Way::
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#drawable/fond"
>
<ImageView
android:id="#+id/imageView1"
android:contentDescription="#string/desc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/top"
android:layout_gravity="top"
android:layout_alignParentTop="true"
/>
<LinearLayout
android:layout_below="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="#drawable/fond1"
>
</LinearLayout>
</RelativeLayout>

How to size a ScrollView to fit 60% of the screen from bottom?

I am trying to create a ScrollView that occupies about 60% of the screen from the bottom. The screen is in landscape mode and the scrollview is the only view element in this activity. I can get it to work on a 800x480 emulator screen by forcing layout margins (see XML code below) but when I switch to a higher res screen the scrollview will occupy more than 60% of the screen and as a result it covers up some of the information on the background image. Can someone please advice on how to keep the view at around 60% of screen size, and preferably be able to handle different screen sizes?
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:background="#drawable/safety_base"
android:orientation="vertical"
android:padding="0dp" >
<ScrollView
android:id="#+id/scrollSafety"
android:layout_width="435dp"
android:layout_marginBottom="10dp"
android:layout_marginTop="120dp"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:scrollbars="none" >
<RelativeLayout
android:id="#+id/layoutSafety"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imgSafety"
android:contentDescription="#string/imgSafety_desc"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:src="#drawable/safety_info" />
</RelativeLayout>
</ScrollView>
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="0dp" >
<ScrollView
android:id="#+id/scrollSafety"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="3"
android:background="#android:color/background_light"
android:scrollbars="none" >
<RelativeLayout
android:id="#+id/layoutSafety"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/imgSafety"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:contentDescription="Blah blah"
android:src="#drawable/icon" />
</RelativeLayout>
</ScrollView>
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="2"
android:visibility="invisible"
/>
</LinearLayout>

GUI-preview and buttons together

I need to have a video preview(on a Surface) and a TextView and a few buttons(at the bottom of the screen)
Currently, my preview's height is large but it's narrow and at the far left at the screen and the TextView is not visible.
The buttons are placed at the bottom as I require.
How do I make the preview's width large as well and the TextView visible?
Here is my layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Android Recorder"
/>
<SurfaceView android:id="#+id/camsurface"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1" />
<TextView
android:id="#+id/recording_time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=" 00:00"
/>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<Button android:id="#+id/btn_settings"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Settings"/>
<Button android:id="#+id/btn_record"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Record" />

Your "preview is very small" is very small because you have it set for 140px square, hard-wired in your layout.
Either take advantage of android:layout_weight with LinearLayout, or use RelativeLayout, to make your SurfaceView take as much space as is available.
For example, here is a layout with a Button at the bottom and a WebView filling up all remaining space:
<?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"
>
<WebView android:id="#+id/webkit"
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1"
/>
<Button android:id="#+id/helpcast"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="View Helpcast"
/>
</LinearLayout>

Corrected :
<?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"
