I want to align those elements to the bottom of the image that i have:
here is a
expected results:

Scale imageview on tablet with original aspect

I have the code below and I face a problem with the image view "#+id/logo_skilfull" because it does not keep the aspect.. I think is because of the scaleType or the adjustViewBounds..

You should read about the ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
This is a problem changing the size of the View. You need to set scaleType.
Try fitStart.
<ImageView
android:id="#+id/logo_skilfull"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_gravity="center"
android:layout_marginLeft="10dp"
android:layout_marginTop="10dp"
android:background="#drawable/logos"
android:scaleType="fitStart"
android:layout_alignParentBottom="true" />

Displaying Button Above Image in Android

I am making an android application in which i have an ImageView and an Forward Arrow Button ,All i want is to display the button at the Right Center of the screen above the image.
Here is my code.....
<ImageView
android:id="#+id/ImageShow"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<EditText
android:id="#+id/postal_address"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="#string/postal_address_hint"
android:inputType="textPostalAddress" />

Maybe you can try something like this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="#+id/ImageShow"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:id="#+id/YOUR_BUTTON_ID"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#id/ImageShow" />
</RelativeLayout>

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_alignParentRight="true"
/>
</RelativeLayout>

I am working with android and I have designed my xml in which I am showing three buttons at the bottom of my screen and also I am showing a textbox (textboxA) at the center of my screen along with three buttons at the bottom of the screen.
Now I would like to show three labels and three spinners just below the textboxA Is possible to do? I tried using the below code but some of my labels and spinners are off
textboxA
labelA: SpinnerA
labelB: SpinnerB
labelC: SpinnerC
Below is my xml layout -
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:id="#+id/button1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="ButtonA" />
<Button
android:id="#+id/button2"
android:layout_width="0dp"
android:layout_height="wrap_content"

</EditText>
<TextView

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:text="Radius1: " />
<Spinner
android:id="#+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/edittext"
android:layout_centerHorizontal="true" />
<TextView

<Spinner
android:id="#+id/spinner3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/edittext"
android:layout_centerHorizontal="true" />
Is there anything wrong I am doing here?

If you are using RelativeLayout you should use toLeftOf or above or below xml properties in the items to define their positions
Edit:
Try this layout, obviously you will have to tweek it a bit to fullfil your needs:
<RelativeLayout 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" >
<EditText
android:id="#+id/edittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:ems="10"
android:hint="textboxA"
android:inputType="text" >
</EditText>
<LinearLayout
android:id="#+id/firstRadius"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/edittext" >
<TextView
android:id="#+id/text_view_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radius1: " />
<Spinner
android:id="#+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:id="#+id/secondRadius"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/firstRadius" >
<TextView
android:id="#+id/text_view_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radius2: " />
<Spinner
android:id="#+id/spinner2"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
<LinearLayout
android:id="#+id/thirdRadius"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#+id/secondRadius" >
<TextView
android:id="#+id/text_view_3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Radius3: " />
<Spinner
android:id="#+id/spinner3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:orientation="horizontal" >
<Button
android:id="#+id/button1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="ButtonA" />
<Button
android:id="#+id/button2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="ButtonB" />
<Button
android:id="#+id/button3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="ButtonC" />
</LinearLayout>
</RelativeLayout>
Hope it is helpful.

Android scrollview scrolls more than needed

I added scrollview to a relative layout, but it scrolls more than I needed. If I remove the scrollview, it will not show the last two buttonImages. So I added srollview.
Here is the code.
<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>
</ScrollView>
I tried changing lots of things, but I can't make it work.

Would using a LinearLayout help? I'm not sure you need a RelativeLayout inside the ScrollView with just those buttons listed there.
Something like this (extra properties, ids, etc. need adding)...
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:background="#drawable/background_image"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<!-- Add buttons here... -->
</LinearLayout>
</ScrollView>
This will scroll if it needs to, and not otherwise.
