Android: Umano AndroidSlidingUpPanel Sliding two Panels?

So I started using Umano's AndroidSlidingUpPanel library and it's very useful. I managed to implement ONE sliding panel from the bottom which worked very well. However I want to implement two Sliding panels (top and bottom) such as this:
This is what I have so far:
<?xml version="1.0" encoding="utf-8"?>
<com.sothree.slidinguppanel.SlidingUpPanelLayout xmlns:sothree="http://schemas.android.com/apk/res-auto"

android:layout_height="wrap_content" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
</LinearLayout>
</com.krish.horizontalscrollview.CenterLockHorizontalScrollview>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Hi"
android:textSize="16sp" />
</LinearLayout>
</LinearLayout>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center|top"
android:text="The Awesome Sliding Up Panel"
android:textSize="16sp" />
</com.sothree.slidinguppanel.SlidingUpPanelLayout><LinearLayout>
How do I add two Sliding Panels to a view? :)

try to set the parameter rotation = "180" of
com.krish.horizontalscrollview.CenterLockHorizontalScrollview

LinearLayout and TextView doesn't show properly

I'm trying to create a new LinearLayout and now i have added a text and a background and now the background appears and still not full as it seems in the graphical they both show up in the graphical layout
example here:
https://www.dropbox.com/s/k58uznho9pu5qky/Untitled1.png
and when i test it out in a emulator which is real device the background isn't showing probably with some white space down and the text doesn't even appear
example here:
https://www.dropbox.com/s/q9e45sunbsesrd1/uniteled3.png
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/relLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="right"
android:orientation="vertical"
tools:context=".SecondActivity" >
<LinearLayout
android:id="#+id/linearlayout2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/images"
android:gravity="center|right"
android:orientation="vertical" >
<TextView
android:id="#+id/two"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingTop="10sp"
android:text="testing ytestifnfndfijdfhffdkjdfkjfdjkj"
android:textSize="25sp" />
</LinearLayout>
</ScrollView>

How does this fit your needs? If you plan to add more content, then the root component can be ScrollView with the background. But with only one TextView, there should be no need for ScrollView unless the text is huge.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:ads="http://schemas.android.com/apk/lib/com.google.ads"
xmlns:tools="http://schemas.android.com/tools"
android:background="#drawable/images"
android:gravity="center"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".SecondActivity" >
<TextView
android:id="#+id/two"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="testing ytestifnfndfijdfhffdkjdfkjfdjkj"
android:textSize="25sp" />
</LinearLayout >

to fill whole screen with your layout use match_parent for layout_height and layout_width
<LinearLayout
android:id="#+id/linearlayout2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/images"
android:gravity="center|right"
android:orientation="vertical" >

Unable to make all UI components appear in RelativeLayout

I want a RelativeLayout based android UI that looks like the below mock graphic:
Below is my layout xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayoutForPreview"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- surface view that contains camera preview , and seats above #+id/linearLayoutToolbar -->
<SurfaceView
android:id="#+id/surfaceViewBarcodeScanner"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<!-- LinearLayout that contains toolbar that is divided into 3 sections horizontally -->
<LinearLayout
android:id="#+id/linearLayoutToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/surfaceViewBarcodeScanner"
android:orientation="horizontal" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/scanner_bottom_left" />
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/scanner_bottom_center_toolbar" />
<ImageView
android:id="#+id/imageView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/scanner_bottom_right_landscape_button" />
</LinearLayout>
</RelativeLayout>
I used Eclipse GUI palette and my own editing , however the output was not what I expected, the SurfaceView seems to covering all the screen, the LinearLayout at the bottom does not appear.
Snapshot of my current result on Galaxy S3 device:
Any help will be appreciated, Thanks.

Could you please try out to modify your layout as the follows:
Define your SurfaceView and set it's layout_above value to the ID of the linear layout made in the previous step. Set the layout_alignParentTop to true.
Define your bottom linear layout and set the layout_alignParentBottom to true.
Smart code snippet with only the important parts:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android">
<SurfaceView
android:id="#+id/surfaceViewBarcodeScanner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_above="#+id/linearLayoutToolbar" />
<LinearLayout
android:id="#+id/linearLayoutToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
</RelativeLayout>
I hope this will solve your problem.

you can use Linearlayout instead of Realtive Layout
<?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" >
<SurfaceView
android:id="#+id/surfaceViewBarcodeScanner"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1" />
<LinearLayout
android:id="#+id/linearLayoutToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<!-- inside elements -->
</LinearLayout>
</LinearLayout>
else you should use android:layout_above="#+id/linearLayoutToolbar" to your surfaceview
and remove android:layout_below attribute and add android:layout_alignParentBottom="true" to your toolbar view.

// try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/LinearLayoutForPreview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="5dp"
android:orientation="vertical">
<LinearLayout
android:layout_height="0dp"
android:layout_weight="1"
android:layout_width="match_parent">
<SurfaceView
android:id="#+id/surfaceViewBarcodeScanner"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<LinearLayout
android:id="#+id/linearLayoutToolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="0dp"
android:gravity="center"
android:layout_weight="1">
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/scanner_bottom_left" />
</LinearLayout>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="0dp"
android:gravity="center"
android:layout_weight="2">
<ImageView
android:id="#+id/imageView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/scanner_bottom_center_toolbar" />
</LinearLayout>
<LinearLayout
android:layout_height="wrap_content"
android:layout_width="0dp"
android:gravity="center"
android:layout_weight="1">
<ImageView
android:id="#+id/imageView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/scanner_bottom_right_landscape_button" />
</LinearLayout>
</LinearLayout>
</LinearLayout>

How can I use LinearLayout two times with different postions ? center and bottom

I wanna to add one button in the center, and two in the bottom (one on the lift and the second on the right) using linearlayout programmatically if that possible ?
best practice and different idea are welcome too
A picture attached, Thanks in advance

<?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:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:gravity="center" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Center Button" />

Setting textbox width to the remaning width

Please have a look at the following code
<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="vertical"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/firstNumber"
/>
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
</LinearLayout>
In here, the size(width) of the text box is very small. I am trying to set it to fit to the remaining width, but as you can see, it fails. I have used android:weight=1 as well. Please help, how can I set the width of the text box to the remaining width?

Maybe you need to change the horizontal LinearLayout like below. Change width to match_parent
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
and add android:weight=1 to the textview

Try this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#FFFFFF"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/firstNumber"
android:layout_weight="0"
/>
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>

Try giving the layout_width of inner LinearLayout as match_parent
android:layout_width="match_parent"
