Please help my ListView stop vertical scrolling - android

I've created a ListView in a nested LinearLayouts with Horizontal scrolling in an attempt to display long records with the capability for Horizontal scrolling, but now I'm unable to scroll the ListView vertically.
Here is my XML setup. Can you help me figure out why the ListView stop scrolling. I've found several article tried difference Width, Height and Weight layout, but nothing seems to work.
Thank you in advance for your help.

I've figured out what to do. This is probably not the best way, but it work for us. I put the column headers one linear layout and the ListView in another. Thanks.

Could anyone help me find the reason as to why this won't scroll? Inside the relative layout I have textViews, spinners and editTexts. I'm pretty new to android and xml so I have no idea why it's not scrolling.
Edit: here is the full layout as requested.

Based on your code you don't need the parent linear layout. Try to delete it and use the scrollView as parent. And also remove the orientation and scrollbars attributes to the relativeLayout, you don't need them.

Android SDK: RelativeLayout - Button WILL NOT center horizontally, even with Layout_CenterHorizontal=true

I really hope somebody can help me here because I am going to start pulling my hair out if this keeps doing what it's doing.
I'm trying to design a layout and I want all of my stuff to be centered. So far, everything is. However, the Save button I created will not center itself for the life of it. It consistently aligns its left edge with the center of the screen, rather than the center of the button itself.
Below is a screenshot of my simple design and the xml behind it... Any help will be GREATLY appreciated!

Something like this ? It can be done much easier in LinearLayout though.

Android RelativeLayout, hiding views and pushing the views beneath up

I have a RelativeLayout which includes a Spinner and some RadioButtons, based on the selection of these I have to hide some views and make others visible. The problem is if I make the views GONE by view.setVisibility(View.GONE) the layout gets messed up, the views overlap, if I use view.Visibility(View.INVISIBLE) everything is fine but the missing views create a void on the page. I want to push the views beneath up to properly augment the page. Below is a better explanation:

You should use alignWithParentIfMissing attribute.

Use LinearLayout(vertical) inside ScrollView and create RelativeLayouts as child of this LinearLayout. Set height of these RelativeLayout as wrap content, so that as you set visibility of items as GONE its height will shrink.
Now as per image that you have given here, you can have spinner first then below that a relative layout which will contain two (horizontal) items that you wanna hide. then next two (horizontal) items in another layout and then your image, editText and Button in third layout.
So you hide any relative layout others will arrange properly.

I would recommend to create a view of height 1dp with transparent background below texView4 and then set android:layout_below="#id/view" attribute for textView5. Here is how the changes to the layout would look like:
</RadioGroup> <!-- RadioGroup ends -->
<View
android:id="#+id/view"
android:layout_width="match_parent"
android:layout_height="1dp"
android:layout_below="#id/textView4"
android:background="#color/transparent"/>
<!-- Changed layout_below attribute value -->
<TextView
android:id="#+id/textView5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/spinner1"
android:layout_below="#id/view"
android:layout_marginTop="25dp"
android:text="xxx"
android:textColor="#002f44"
android:textSize="18sp" />
And here is how the layout looks like with textView4 and RadioGroup gone:

And when I tried to add the following after defining RelativeLayout and before closing RelativeLayout, it broke the app immediately when I run it.
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent"

...........
</ScrollView>
How can I make it scrollable?

Your app crashes because ScrollView can host only one direct child.
Direct from official documentation:
Layout container for a view hierarchy that can be scrolled by the
user, allowing it to be larger than the physical display. A ScrollView
is a FrameLayout, meaning you should place one child in it containing
the entire contents to scroll; this child may itself be a layout
manager with a complex hierarchy of objects. A child that is often
used is a LinearLayout in a vertical orientation, presenting a
vertical array of top-level items that the user can scroll through.
Look this http://developer.android.com/reference/android/widget/ScrollView.html.
To solve your xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Hope help you

I think you must enclose your relative layout in your scrollview ( before defining and after closing ) .
EDIT : You must also enclose your relative layout in Liner Layout
ex :
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
android:stackFromBottom="true"
android:transcriptMode="alwaysScroll" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/background"
android:paddingBottom="16dp"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:paddingTop="16dp"
android:textDirection="anyRtl"
tools:context=".AddDiscountActivity" >
</RelativeLayout>
</LinearLayout>
</SrcollView>

Please help my ListView stop vertical scrolling - android

I've figured out what to do. This is probably not the best way, but it work for us. I put the column headers one linear layout and the ListView in another. Thanks.
