ScrollView and Wrap_Content not work

I have a problem in my xml, the ScrollView does not work when my RelativeLayout is wrap_content, but if I have a larger screen than the fixed height works correctly, but if I have a larger fixed height than screen the works correctly, but I need to be wrap_content, because I have a listview that is populated gradually as client wants, follows the xml

My listview are configured to not scroll, through code

try do define ScrollView layout_width and layout_height as match_parent, without layout_weight
by the way, you should not mix ScrollView with ListView since both have his own scroll. I suggest to split it like:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
(...)
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>

Why aren't my TextViews getting centered?

I'm trying to emulate a dock for a launcher with 3 text views evenly spaced out across said dock... For some reason I can't get my text views to center align with in there parent linear layouts, can someone please explain to me what is my issue here?
Here is my layout in XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/main_frame"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#FFFFFF" >
<LinearLayout

android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"

Try this out, I think you have too many inner layouts.. you can use layout_weight to achieve this.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/main_frame"

android:background="#FFFFFF"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/footer"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:background="#color/blue"

android:padding="20dp"
android:weightSum="15.0" >
<RelativeLayout

android:layout_weight="5.0" >

Intro layout problems with weight

I am creating an intro activity and What I want is that logo was double bigger than text, and the text was centered to the layout.
With the next code I am having problems with diferents layouts (in some screens the TextView is not shown:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_layout"
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:layout_weight="1" >
<ImageView
android:id="#+id/image_intro"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/image_view_desc"
android:scaleType="fitCenter"
android:src="#drawable/iconok" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_weight="1" >
<TextView
android:id="#+id/email_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="55sp"
android:text="#string/loading_text3" />
</LinearLayout>
</LinearLayout>
What I am doing wrong?

As per your question and comments, I think below snippet will help you.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffffff"
android:orientation="vertical" >
<ImageView
android:id="#+id/image_intro"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="66"
android:scaleType="fitCenter"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/email_textview"
android:layout_width="fill_parent"
android:layout_height="0dp"
android:gravity="left|center"
android:layout_weight="33"
android:text="#string/app_name"
android:textSize="55sp" />
</LinearLayout>

(After your comment) then you should set first inner linear layout's weight 2, and second's 1. Also use layout_height =" 0" for them.
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:layout_weight="2" >
<ImageView
android:id="#+id/image_intro"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/image_view_desc"
android:scaleType="fitCenter"
android:src="#drawable/iconok" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="0dp"
android:gravity="center"
android:layout_weight="1" >
<TextView
android:id="#+id/email_textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="55sp"
android:text="#string/loading_text3" />
</LinearLayout>

test this code :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_layout"
android:layout_width="fill_parent"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="55sp"
android:text="#string/loading_text3" />
</LinearLayout>
</LinearLayout>

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

android:id="#+id/main_layout"
android:layout_width="match_parent"

Try this and change margin according to your requirement.

Change your outer layout to RelativeLayout and position yout ScrollView at the parent center. Position other elements in relation to one in center
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:orientation="horizontal" >
<TextView
android:id="#+id/TextView1"
android:layout_width="151dp"
android:layout_height="fill_parent"
android:textSize="15pt" />
<ScrollView
android:id="#+id/scrollView10"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#000000" >
<TextView
android:id="#+id/textView10"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#000000"
android:gravity="center_vertical"
android:textAlignment="center"
android:textColor="#ffffff"
android:textSize="13sp"
android:textStyle="italic" />
</ScrollView>
</RelativeLayout>

Put the TextView inside of a RelativeLayout, and put that RelativeLayout inside of the ScrollView.
Then, set android:layout_centerInParent="true" within the TextView
