Android :: Child TextView In ScrollView With Large Amount Of Text Pushes Other Views Off The Screen
May 6, 2009I am trying to create an activity layout that has a top level vertical linear layout like so:
CODE:................
This works ok as long as the wordDefinition text isn't very long. But, when I set the text to something very long, it pushes the back button off the bottom of the screen. Why? Isn't the ScrollView supposed to scroll the text in the child TextView?
I've tried playing with weights (e.g., giving the top text view a weight of .2, the scroll view a weight of .7 and the button a weight of .1, but to no avail.
Android :: ScrollView .scrollTo Not Working - Saving ScrollView Position On Rotation
Jul 16, 2010I must be overlooking something real simple here, but i think i'm trying to do something fairly basic.. Simply retain the scrollbar position of a ScrollView on orientation change...
Here is the code for my onSaveInstanceState and onRestoreInstanceState.. sView is the container for the ScrollView layout. Within my scrollview is a linearlayout with a lot of textviews.
CODE:............
If I set a Toast with the values of sViewX and sViewY on the Restore, the values are kept and correct.
I just tried to do a sView.scrollTo(0,150); in my onCreate.. just to see if that would open the activity at 150px down, and it didn't. I think my issue has to do with the .scrollTo method.
Android :: Create A ListView That's Not In A ScrollView - Or Has The ScrollView Disabled
Mar 10, 2010I want some of the goodies in a ListView, like being able to use a ListAdapter, and item selection, etc, but I don't want the ScrollView portion of it. I want to implement that part myself, in a different way (why or how I do this isn't really the point of this question, so please don't ask "why"). Is there a way to have a ListView that's not in a ScrollView or has the scrolling disabled?
View 2 Replies View RelatedAndroid :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background
Jan 6, 2010I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
Android :: How Can Update The All The Views Inside A TabHost When Pressing On A ContextMenu Item From Within One Of The Views
Nov 16, 2010I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

Android :: Switching Views With RadioButton And Saving Views In Bundle
Mar 6, 2010I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.

Jan 25, 2010Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Android :: ScrollView With ListView Being Cut Off
Jul 1, 2009I've got a ScrollView containing a vertical LinearLayout.
The LinearLayout contains several items, including a ListView.
The problem is that I can't seem to get the ListView to be fully expanded. It is being compressed to fit everything on the screen, and forcing me to scroll through just the list. I would prefer to be able to scroll the entire layout, including the ListView.
I've played with the layout parameters a lot, but can't seem to get anything to work.
Also, I'm going to put this in another thread, but thought I'd ask here as well. Is there any way to force a separator at the top of a ListView?
Android :: Don't Put ListView In ScrollView
May 23, 2009I am trying to display a screen filled with data fetched from a server. The data, if it were HTML, would look something like the following (try to visualize =) ):
CODE:..............
So I naively tried to put a ListView in a ScrollView. Not only did it not work, but I've since read all about why it is bad by the likes of such luminaries as Hackborn and Guy (it nullifies the optimizations, etc).
Problem is, the half dozen places that said NOT to do it didn't recommend what I SHOULD do instead, excepting one post by Romain Guy specifying footer or header use (not suitable in my example, right?). In other words, it seems like people want to mix a list of items in among other text data, getting the benefits of a ListAdapter, but this isn't addressed anywhere that I can find.
So, what is The Right Way to implement my example above? I'm a step away from trying to add TextViews inside a for loop, which just doesn't sit right in my gut.
Android :: ScrollView Of WebView?
May 2, 2009I show articles in WebView and would like to add some additional information, e.g. publishing date, author etc., into the same ScrollView above the original content. So that it usually doesn't take up space, but the user can just scroll back when the information is needed.
Did any of you do something like that in a sane way?
I thought I can put my stuff into the same ScrollView that WebView uses, but when looking at it with hierarchyviewer I can't see any children, it's probably native.
Android :: Scrollview And GestureDetector?
Jun 13, 2009I'm making sort of a book app. I have the text displayed as a textview in a scrollview:
CODE:.....
I then have
CODE:...............
And implemented the required following to catch a left fling or right fling. And
CODE:.......
This works fine if the text inside the textview is small (ie. there is no scroll bar as it all fits within the view). But as soon as the text requires scrolling, the gesture is no longer picked up by the detector. onFling is never called.
I have read that it is because scrollview handles its own gestueres? If so what is the easiest way to maintain the ability to scroll up and down the text, and also be able to detect flinging left or right and invoking nextChapter() and previousChapter() respectively?
Android :: Sync Two ScrollView?
Aug 19, 2010I have two ScrollView inside of each of two HorizontalScrollView of a TableRow. When I touch drag one of ScrollView, another ScrollView must scroll as much. For instance, if I have a list of name on left ScrollView and corresponding phone numbers in right ScrollView, scrolling one ScrollView should not destroy the original bounding between the names and phone numbers. Can it be implemented by onTouchEvent? If so, how should I implement this(on both or one of the ScrollView)?

Jul 21, 2010I have an issue with EditText when it's wrapped in ScrollView.
Please see the following layout setup:
CODE:............
There's nothing special about this layout. I just want the EditText inside ScrollView to be scrollable when I entered more than 5 lines of text.
I tested this layout with both Eclair and Froyo and Eclair seemed working fine, but Froyo didn't really work at all. Was there any change on ScrollView?
ScrollView api says that I can put EditText(or TextView) inside of ScrollView to have this kind of functionality, so I guess that I did make a mistake or missed something important.
Android :: How To Scroll Programatically ScrollView ?

Android :: ListView/ScrollView In New Widgets
Apr 30, 2009I found some documentation that said for the 1.5 pre api that ScrollView and ListView are not supported. I used ListViews in my aHome widgets. Does anyone know if there is a way to scroll content in the new Cupcake widgets? I believe there might be a way to scroll plain text, but I need to scrol images as well as text.
I also found this list in an earlier posting to the list: supported Views are: AbsoluteLayout AnalogClock Button Chronometer FrameLayout ImageButton ImageView LinearLayout ProgressBar RelativeLayout TextView
Are these components still the only ones supported?

View 2 Replies View RelatedAndroid :: Can Put A ListView Into A ScrollView Without It Collapsing
Aug 16, 2010I've searched around for solutions to this problem, and the only answer I can find seems to be "don't put a ListView into a ScrollView". I have yet to see any real explanation for why though. The only reason I can seem to find is that Google doesn't think you should want to do that. Well I do, so I did.
So the question is: How can you place a ListView into a ScrollView without it collapsing to its minimum height?
Android :: ScrollView Always Fill Dialog
May 3, 2009Pulling my hair out on this one. I want a dialog that contains a ScrollView with an embedded TextView that will contain what could be a couple of pages of text. Below the ScrollView I want a close button. Everything I try that doesn't involve directly setting the height of the ScrollView results in the ScrollView filling the dialog and the button being invisible because it has been pushed off the bottom. I've tried about every combination I can think of for layout_height and layout_weight of both the ScrollView and the Button but always get the same result.

Android :: More Complex Scrollview Example Needed
Nov 6, 2010I am working on some sort of record lookup for a database. My code allows to search for some kind of string within an index (of that database) and returns the database-position of the found thing . With this found position my program is then able to move to adjacent records from the database moving forward and backwards from the initial position in small steps. ListView seems to not work in this case, as ListView starts per default at ListAdapter position 0 and not at an arbitrary position in the (here virtual) list. The api-docs doesn't seem to specify some sort of "start somewhere else and follow during scrolling". At least I haven't found that. So what I thought of is to use a ScrollView. Unfortunately I don't have a real understanding of how that could be realized with a huge number of records (and not just a handfull like in the examples). So, my questions are: - Is it possible to start a ListView at some defined position (without reimplementing {Abs}ListView) - Or can someone provide an example on how to implement a more complex ScrollView.
