Android :: How To Implement Scrolling Text
Jan 29, 2009
What is the best way to implement scrolling text (with behavior similar to that of HTML tag 'marquee')??
I've been trying to do this using TextViews + Animations but I'm having troubles primarily because of sizing issues. If my text is long enough that it exceeds the screen width, it won't be drawn completely (it's size will be chopped at screen width). Thus, when I animate it from right to left, only a part of the text will be displayed. This happens if I allow a maximum of 1 line in my TextView, because otherwise it makes the TextView have multiple lines. If I make it horizontally scrollable, the same 'chopped-off' behavior is seen.
I think this happens because the TextView's parent imposes some restrictions on its size. Is there a way to bypass these restrictions so that the TextView is 'drawn' even if parts of it will be off- screen?
If that's not possible, what's an alternative way of implementing this behavior?

How to implement scrolling animation? I'm ok with setting a simple AlphaAnimation that triggers at scrollTo(...) but what kind of animation is required for one screen to replace another in a sophisticated manner?

I need to implement a screen having around 1000 thumbnails. This screen should support gesture based scrolling as well as fast scrolling using a scrollbar with thumb. So if user want to move from page 1 to page 100 he can just drag the thumb and reach there. But there is no such control in Android. There is seek bar but its look and feel is not similar to what I want. I also want to flick and swipe functionality which can be inherited using horizontalscrollbar. So i want to add functionality of horizontal scroolbar as well as of seekbar in my application.

Its been a while since I've done any coding, I'm new to android, and unfortunately my first job is rather tricky. My program need to display horizontally scrolling text and images, but it need to set the scroll speed quiet finely. Now I've been looing at some examples with TextView and some also use android.widget.Scroller.
Now I'm pretty sure I'll have to write this from scratch, but what i want to know, is there a clear way that i should use in creating the class. I could try expanding on the TextView class and use its methods. Or should I just write a class to treat text and images the same?

I've been looking around for quite some time now, and I can't get a straight answer for my question. It's quite simple: How can I get a nice scrolling text just like the long app names in the Market when you select an application?

I wish to make a scrolling interface. The screen is populated with images in the left one fourth and corresponding text for an image in the remaining three fourth. There will be n number of image-text on the screen and hence should be scrollable. Also image-text when clicked takes you to a new screen. I seem to be stuck and cant think about which layout should I choose. I am a beginner in Android Developing.

It seems like the best way to create a horizontal scrolling list of images is to use the Gallery widget. I need to display sidebar text with each image.The examples I have seen showing how to use the Gallery widget only show images. Is it possible to display a list of images+text descriptions in a Gallery, and if it is, does anyone have an example of how to do this?

I'm having trouble setting up an Android Layout.
What I would like is a scrollable ListView followed by a small bar of text (TextView) that doesn't scroll and always stays at the bottom of the screen.
it would look like this:
ListViewItem1
ListViewItem2
ListViewItem3
Bar of Text Here (always displayed irrespective of scroll state of the ListView)
I've tried a bunch of different variations on this, but none shows the static text

Simple question - how is text-zooming implemented on an Android/iPhone device? Do they pre-compute frequently used bitmaps of a font and replace the text as the scale changes? Or do they extract the contours from the font files and render the text as vector graphics?

I am trying to create an application which collects a lot of notes from users. I want to implement full text search on the notes so that the user can get relevant notes from the whole array of notes.
I am looking for a solution for this. Full-text-search(FTS) is actually supported by SQLite, but is it available for Android? Can anybody enlighten me on this?

My app builds up a custom screen as dictated to me via the users 'application'. This means that I can end up in the situation where I have a parent scrollview and somewhere down the heirachy I can have a listView or a multiline TextView. Both of these scenarios continue to work fine under 2.1, however are broken in 2.2 (both device and emulator). The symptoms are that the child (list or textview) is unable to scroll using touch gestures although they can be scrolled using the keypad. Has anyone else experienced this behaviour and/or have a work around?? It appears that the onTouchEvent function in View has been changed substantially but I am currently delving into the code...

I'm trying to make a layout that is something similar to how the android market is...where say under comments there is what appears to be a ListView but it does not scroll (the whole page scroll but not the comments). I'm not sure if its even a ListView but I want something that looks like the list view (ie. have those divider bars and what not but NOT SCROLLABLE). There are people suggesting to use a LinearLayout instead of a ListView but I also what the items to be clickable and open a new activity. Please help?
My current layout tree is like so
<LinearLayout>
<ScrollView>
<RelativeLayout>
I am looking to put content inside the RelativeLayout.

Just wondering if anyone knows of a way to invert scrolling so that you swipe down-to-go-down and up-to-go-up instead of the way it is by default: up-to-go-down and down-to-go-up?The only reason it's a problem for me is that I have a laptop and use two-finger-scrolling on the trackpad (down-to-go-down/up-to-go-up). This means that when I switch from one to the other, I keep trying to go the wring way with my swipes. Confusing. I looked through all of the settings on the phone and tried googling and looking through the available apps but to no avail.

I have a gallery and when a image is selected, I want to start new thread (for loading other images). But I don't want to do it while the gallery is scrolling. How can I know the state of the gallery and if it is still scrolling? I can't use "setCallbackDuringFling(false)" because I have a textview under the image that has to be updated during the scrolling.

I have a ListView with custom rows. When any of these rows is clicked, the ListView's data is regenerated. I'd like the list to scroll back to the top when this happens.
I initially tried using setSelection(0) in each row's OnClickListener to achieve this but was unsuccessful (I believe because the ListView loses its scroll position when its data is invalidated - so my call to
setSelection is undone. I still don't understand how the ListView decides where to scroll to after invalidation, though).
The only working solution I know of was given by Romain Guy here: http://groups.google.com/group/android-developers/browse_thread/thread/127ca57414035301
It involves (View.post)ing the call to _listView.setSelection(0). I found this to perform quite poorly.
The newly generated list shows up with its scroll location unchanged and there is a considerable delay before it scrolls back to the top.
Is there any better way to achieve this functionality?

I currently have one Scrollview which contains a table layout and one list in my activity. Now my problem is that I wanted to move both of them(Scrollview and list) together and with proper synchronization...
So if scrollview is being scrolled then listview should also scroll with the same distance, and vice versa...

I'm currently working on a game for android.
I have three ImageView's next to each other, they're positioned next to each other using the "android:layout_toRightOf". The views are located within a RelativeLayout tag. Each of these views are centered into the middle of the screen using "android:scaleType="fitCenter"" and they fill the entire screen.
I'm attempting to implement a horizontal scroll from one view to another so that I basically get one view on my screen at a time.
Here is the code that I'm currently using
CODE:................
What I'm currently getting is three images next to each other -- but sometimes they take up less then an entire screen. I want both the left and right padding to be correct, so that I can only see one image at a time.

I have an ImageView that is twice the height of a normale screen ( 960 dip). I would like to scroll it nicely up and down on the screen. The bottom of the screen should contain a bottom. I have tried various combinations of ScrollView and Imageviews without any success. I have also thinkered with the :isScrollContainer attribute without results. Anyone knows how to do this?

I have a widget that periodically updates itself (hourly) to display top result of search query. I would like to extend it so it captures several top results and then loops through these. The best example would be Genie News and Weather widget for which I was unable to find a source code. What would be a good way to implement the animation? I'm thinking ViewAnimator + timer, but is there maybe a better way, say FrameLayout + alerts? I'm already using AlertManager to periodically pull search results for the widget How bad such arraignment would affect phone's battery life?
