Button at the bottom of ScrollView with ListView inside

I have a layout, something like a page. I have a list view and at the bottom of the list i need to have a button. It has to be under the List View, not sticking at the bottom of the screen. (Like you have to scroll all the way down through the list to get that button.) The structure I am using:
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ListView
android:id="#+id/show_list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:dividerHeight="7dp"
android:paddingHorizontal="25dp"
android:scrollbars="none"
android:scrollingCache="false" />
<LinearLayout>
//My button here
</LinearLayout>
</LinearLayout>
</ScrollView>
MAIN ISSUE: Scrolling ends at the last item of ListView, Button stays out of screen. Why is that so? (I tried disabling list scrolling with isVerticalScrollBarEnabled, but it didn't make any difference.)
EDIT: Now, as I switched order of the button and the list, I found out that I am scrolling ListView, not ScrollView, so the issue is I need to do scrolling of ScrollView, not ListView. How to do that?

So I found out that ListView in a ScrollView is a bad practice, I used ListView footer feature instead, having button in the seperate layout, then adding it through code. It works perfectly.

ScrollView doesn't work

My Layout has a few complex layouts and they are pretty big. That's why I need a ScrollView. But whatever I try it doesn't work.
Here is my layout file:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="match_parent"
android:layout_width="fill_parent"
android:fillViewport="true"
android:layout_weight="1"
android:orientation="vertical"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:weightSum="1">
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.33"
android:id="#+id/Linear1"
>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#color/tileColor1"
android:layout_weight="1"
android:id="#+id/tileLayout1"
android:onClick="openFirst"
>
I have only posted a part of it but all the closing tags are ok and inside my RelativeLayout there are 2 textViews and an image. There are 9 more RelativeLayouts with the same structure.
How can I fix the problem and why doesn't it work? It doesn't even show a scrollbar.
EDIT
I have uploaded my full layout to pastebin
EDIT 2
On the developer.android it is said:
You should never use a ScrollView with a ListView, because ListView takes care of its own vertical scrolling. Most importantly, doing this defeats all of the important optimizations in ListView for dealing with large lists, since it effectively forces the ListView to display its entire list of items to fill up the infinite container supplied by ScrollView.
Mine doesn't deal with the scrolling at all. I suppose it is this way because I edit LayoutParams in code. How do I fix this?

1. Try removing android:layout_weight="1" and android:orientation="vertical".
2. Ensure that there is only one ViewGroup inside the ScrollView (i.e. one child as they say). I assume you've done this, but as you haven't provided your full layout I couldn't confirm it.

ScrollView only accepts one child view. So wrap everything inside it in a LinearLayout with wrap_content set as height and you're set.

I had the same problem, and I do not know if my solution helped (mainly because it is a very late response), but my ScrollView not worked since set up a layout that fit exactly on the screen, so it was not necessary to create scrolling. When increased my layout (I put all my items with
android:layout_height = WRAP_CONTENT) became operational.

Why is Horizontal Scrolling is not working when a List View is placed inside a horizontal ScrollView?

I have a simple list view which is placed inside a Horizontal Scroll view so that I can scroll horizontally when the list view content is too long. When I place Text View inside the horizontalScrollView, I could scroll horizontally. But, with list view it doesn't work.
Any body had the same issue? Any work around for this?
<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/newListBoxContainerHSV"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true"
android:background="#FF00FF">
<ListView
android:id="#+id/list_view"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#FFFF00"
>
</ListView>
</HorizontalScrollView>

Because ListView is not meant to be put inside any ScrollView. It's considered a bad practice, as ListView itself has a built-in ScrollView and you may use it, so try avoiding at any price a ListView inside a ScrollView.
If necessary, redesign your layout to not need it, as it goes against Android's design.

Trying to get textView to stick to gridView scroll

I have a fragment with a textView giving instructions, and below a gridView. I wanted for the textView to scroll upwards with the gridView. In other words: for textView to disappear off screen when gridView is scrolling.
My idea of how to accomplish this is to give the gridView a fixed height that would make the entire layout scrollable - including the textView. However, up until I cannot achieve this. Is there a way to do this?
Layout no scroll:
When scrolled:
Any help/advice would be appreciated.
My layout XML:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#color/LightGrey"
android:gravity="center_horizontal|center_vertical"
android:orientation="vertical" >
<TextView
android:id="#+id/chooseLine"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="18dp"
android:text="#string/chooseLine"
android:textAppearance="?android:attr/textAppearanceLarge" />
<GridView
android:id="#+id/gridLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:columnWidth="130dp"
android:fitsSystemWindows="false"
android:gravity="center"
android:horizontalSpacing="5dp"
android:numColumns="auto_fit"
android:paddingTop="0dp"
android:stretchMode="columnWidth"
android:verticalSpacing="25dp" />
</LinearLayout>

Achieving this is is not going to be trivial. What you need is ListView's capability to add a header view, but unfortunately, GridView doesn't offer that functionality.
What I have done in the past to solve this problem is to convert the GridView to a ListView, and then add the header to the ListView. I created a wrapper adapter that takes the original adapter and combines a horizontal row's worth of grid cells into a single list row.
The tricky parts include: dynamically adapting the number of columns in a row based on the width of the screen, accounting for all combinations of view types within a row and remaining empty columns in the last row, and handling click interactions properly.

Put the whole LinearLayout in a ScrollView (How to use ScrollView in Android?) and for the GridView set android:layout_height="wrap_content"

Getting a button to scroll into view at the bottom of a GridView on Android

I am trying to port an existing iPhone application to android. I wish to have a button scroll into view at the bottom of a GridView to enable the user to load more data from the server. Presently, my solution simply fixes a button at the bottom of the screen instead of having it scroll into view.
Here is my layout code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:columnWidth="70dp"
android:numColumns="auto_fit"
android:verticalSpacing="0dp"
android:horizontalSpacing="0dp"
android:stretchMode="columnWidth"
android:gravity="center"
android:background="#000000"
/>
<Button
android:id="#+id/load_more"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Load More"
/>
</LinearLayout>
Fixing the button at the bottom of the screen won't work because I plan on placing an ad at the bottom.
Can anyone either explain conceptually how to get a load more button to scroll into view, or point me to some sample code, OR tell me why this is not idiomatic to Android and what other UI convention it uses to load more data in a GridView?
Thanks!

You can place a ScrollView inside your main LinearLayout. A ScrollView can only have one direct child, though, so you'll need to put another LinearLayout inside of it which would then contain your GridView and Button.

I had a similar problem with scrolling a GridView and after refreshing the underlying data, noticing that the scoll was not reset to the beginning. I solved it with the following code fragment
gvKeys.setSelection(0);
I'm guessing that if you know the number of items in your grid, N, that the following will work:
gvKeys.setSelection(N);
