Android :: Scrollview And GestureDetector?

Jun 13, 2009

I'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 :: ScrollView .scrollTo Not Working - Saving ScrollView Position On Rotation

Jul 16, 2010

I 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 :: Performance Of GestureOverlayView And GestureDetector

Aug 24, 2010

I am using GestureOverlayView with ViewFlipper, and it takes about one second for the android to recognize my gesture and flip to next view. However, the Android calendar flips almost immediately. I checked the Android calendar code, and it uses GestureDetector. Is there big difference between these two gesture detecting mechanisms?

I am also wondering what's the difference between these two mechanism of detecting gestures. I know GestureOverlayView came out at 1.6, while GestureDetector was in 1.0. But why didn't they just deprecate GestureDetector when GestureOverlayView came out?

Android :: Create A ListView That's Not In A ScrollView - Or Has The ScrollView Disabled

Mar 10, 2010

I 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?

Android :: ScrollView With ListView Being Cut Off

Jul 1, 2009

I'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, 2009

I 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, 2009

I 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 :: Sync Two ScrollView?

Aug 19, 2010

I 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)?

Android : Chart Using Scrollview

Sep 8, 2010

I want to draw a chart and I'm using a scrollview to do so. my scrollview holds the chart view. What I've observed is that the scrollview's onDraw calls the onDraw of my chart view. Now I draw the entire chart on the canvas when the onDraw of chart view is called. Also scrollview's onDraw is called everytime I scroll the view. So I end up drawing the entire chart multiple times. Is there any better way to achieve what this

Android :: EditText Wrapped In ScrollView

Jul 21, 2010

I 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.

</LinearLayout>In onCreate method of my activity I compute ListViews height according there contents.During execution, on activity launch, ScrollView is already scrolled a bit.So I tried, at the end of onCreate to call method scrollTo(0, 0), but it does not change anything.

Android :: ListView/ScrollView In New Widgets

Apr 30, 2009

I 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?

Android :: Can Put A ListView Into A ScrollView Without It Collapsing

Aug 16, 2010

I'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, 2009

Pulling 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 :: ScrollView Is Not Calling OnDraw / Way To Fix?

I hope this question belongs in the Android Developers and not Android Beginners group but I have a question about ScrollViews. I am currently working with a customized GraphView class and am trying to put it into a ScrollView but it doesn't seem to work. Whenever I run the code, it comes up with a blank screen. I've written the code in XML and also tried to create the ScrollView encapsulating the GraphView programmatically but whenever the code runs, it comes up with just a blank screen and GraphView's onDraw() is never called.Code...

Android :: Limit Size Of ScrollView

Jul 26, 2009

I am using a ScrollView as a child of an AbsoluteLayout to display a list of items inside this AbsoluteLayout. Because the ScrollView is embedded in the AbsoluteLayout's design, I want to restrict it's size to fit the assigned area. Is there any way to set the height of the ScrollView or of the RelativeLayout that is the child of my ScrollView? My layout.xml (with just the important tags):

<AbsoluteLayout android:layout_width="fill_parent" android:layout_height="fill_parent" /> <...some TextViews...>
<ScrollView android:layout_width="wrap_content" android:layout_height="wrap_content"> <RelativeLayout android:layout_width="wrap_content" android:layout_height="wrap_content"> <...some TextViews that I want to be able to scroll, all with wrap_content...> </RelativeLayout> </ScrollView>
<...again, some TextViews in the main layout...> </AbsoluteLayout>

To make it clearer, I have uploaded two images of what I am trying to do: http://drop.io/v8qobow/asset/current-jpg http://drop.io/v8qobow/asset/goal-jpg

Android :: More Complex Scrollview Example Needed

Nov 6, 2010

I 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.

Android :: Scrollview Vertical And Horizontal

Jan 11, 2010

I'm really tired looking for a solution for Scrollview vertical and horizontal. I read that the any view/layout implements this feature in the framework but i need something like this. I need to define a layout within other, the child layout must implement scrolling vertical/horizontal for moving. Initially implemented a code that move the layout pixel by pixel, but i think that is not the right way. I tried with ScrollView and HorizontalScrollView but any ones work like i want, because only implement vertical or horizontal scrolling.

Android :: Layout With ScrollView And TextView

Apr 1, 2010

I want to have a textview (like a console or output window), which scrolls. I saw on this list that the TextView will not scroll on its own unless I wrap it in a ScrollView. So I did that and it worked. The problem is, it seemed no matter what I did I could not get the TextView to be higher than one line. This was only when it was embedded in the ScrollView, and didn't seem to change whatever I set the TexView's layout_height to.

Here is my layout:
