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.

I have created a listview inside scrollview. Atfirst it was not scrolling but when it started scrolling then layouts below list view started disappearing from screen. is there any solution to dynamically calculated he height of list view and assign it or is it possible that some how the scrolling of listvew is disabled so that only its items appear on screen like normal layouts or any tags and it does not scrolls???
ListView is deprecated. I would suggest you to use RecyclerView and add nestedScrollingEnabled="true" to your xml or call RecyclerView.setNestedScrollEnabled(true) if you want to wrap adapterview with a scroller. You can also try NestedScrollView for support compability.
Good luck
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.
Hello, I have a question,
Is there any possibility to skip the first scroll's that occur before gridView is loaded?
To get only those when user really scrolls my list?
I am loading more, and that scroll before any user action is messing up.
How are you loading the gridView?
If you load it using addView you probably won't have problem.
In my opinion the best solution is to create a scrollView that contains a LinearLayout (for example vertical), then add at this LinearLayout a list of LinearLayouts (horizontal), and every layout contained in list contains yours elements.
I'm implementing a listview that looks like this :
So basicly I have a listview, with a headerview. My problem is to set the space between the headerview and the rest of the listview. If anyone has a clue, thanks :)
To set a gap below the header view you can just add marginBottom to the header view. That should do it. But like Pauland said, never ever EVER put a listview inside a scrollview. You are basically placing two vertical-scrolling views ontop of each other and Android can't tell which one to scroll when the user swipes!
I'm having abit of an issue and i'm not too sure how to go about solving it.
Essentially i have an activity which has a base xml layout of ScrollView and i want this activity to list some results from a Cursor. So i thought i'd use SimpleCursorAdapter... however when i got it all set up it appears that the ListView that the SimpleCursorAdapter goes into doesn't play nice being within another scrollable layout element.
I've sorta got it working programmically but i'd much rather use a ListAdapter as it will make each list entry look like a button and keep it inline with the design of the rest of the application and can handle the ids of each item and where to send the user upon clicking.
So my question is this: is there anyway to either make ListView show all the items such that it never needs to scroll, or can i change the ListView to something like a LinearLayout?
I hope that makes sense!
Any help / insight / ideas are welcome!
Cheers!
You can NEVER use a scroll view and a ListView together. Its a mess! and illogical as well.
Here are some of the approaches you can use:
Theres no screen big enough to show all the content of you listView you can try wrapping up your content but as I said it won't help as scroll view and list view don't work together. So you can either remove your or
If your list items are simple you can dynamically add your views to LinearLayout with specified location
Another tip I can give you is you can always use an relative layout and place your listView alignParentBottom="true" and emit the scrollView approach this will make you listview alwyas scrollable.
It doesn't really make sense to have a ListView inside a ScrollView at all. The ListView implements it's own scroll function so it should not be used in conjunction with a ScrollView anyway.
You should rethink your UI design.
I agree with Shardul; trying to put a listview with a scrollview will make it impossible to scroll. Have a look at the links below to see what you can accomplish with just a ListView -
