I am looking that when i scroll the listview the whole page gets scrolled.
I don't know what it is exactly that you want, but never put a ListView inside a ScrollView! ListView does its own scrolling.

I have a listView, with a footer attached to it, which is Button. This Button works fine when there is no Scrolling involved.
When the listView is scrolling, it becomes unclickable, like the other items in the ListView. Since it takes some time after the View have reached bottom, and the View actually stops "Scrolling", the footer(Button) is unclickable for a sec or 2. Is it possible to make an item, in this case a ListView footer, clickable while the ListView is scrolling? Or another clever solution to this issue?
try to make the button.setClickable(true). it should be clickable during the scrolling
This sounds like another one of a very long list of problems with ListView stealing touch events from its child views. The solution is to use RecyclerView instead. ListView is essentially deprecated and RecyclerView is the replacement.
Here I am attaching one image displaying what i want to achieve.
Now, what i want to do is, when the scrollview scrolls upwards, its should scroll the "somedata" "header" and "listview" part behind the image. I have already achieve this.
Next thing should be done is when "header" comes exactly below the "Imageview" while scrolling, it should stick there and then we must be able to scroll the other items of listview.
Can anyone help me ?
First of all, you can not use ListView inside ScrollView.
You can combine your "Some data" and "header" into single layout and set whole layout as your listview HeaderView.This will make your list scrollable with header.
I have an HorizontalScrollView in my design, which I populate with a variable number of items. The problem I have is that sometimes I populate it with many items, so the ScrollView shows scroll bars. That's OK, but I would like to check this situation and show a Previous and Next buttons in this case.
How can I do this?
I don't think ScrollView has a scroll listener. Synchronise ScrollView scroll positions - android might help you for creating a custom one.
I'm running into a problem and i can't figure out how to implement it. I have many controls in my Linear layout and a Listview. Because I have many controls controls in my screen so i hadto implement scrolls in my layout BUT after i get through the listview it again has its scrolls so i have 2 scrolls in my screen. My question is how to disable the ListView scrolls and view all it's cells in the screen so that the user can scroll from the main scrollview.
Any help would be appreciated !

lv.canScrollVertically(0);
I am adding a listview inside a scrollview in xml that xml(Screen) is loading from the middle screen. In my design I have a top part like a textview and a list view and middle part like editext and bottom part like button. Page is loading from the middle part. If it scrolls I can only see the above part. I want to load the page from above part. Can anybody tell me what the problem is and how to resolve it?
Thanks
Use android:fillViewport="true" as an attribute in your scrollview tag and it will fill up the screen.
Actually there is no need to use ScrollView with ListView. Use ListView only, you will be able to scroll the items in a ListView.
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.
