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?

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?
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.
View 1 Replies View RelatedI 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?
View 1 Replies View RelatedI'm fading out an imageview with alpha animation. I'd like the image to stay transparent after the animation. Tried with different combinations of fillAfter and fillEnabled, no luck. How can this be achieved?
View 1 Replies View RelatedI have a strange issue - from time to time the animation that should fade out my control (ImageButton) does not kick in immediately. I am using the fadeout animation to hide it and then in myListener on its end (onAnimationEnd) I put new resource as the image on the button.
Somewhere in my app code:
Animation a = AnimationUtils.loadAnimation(this,R.anim.fadeout); a.setAnimationListener(new myListener(location)); buttons[location].setAnimation(a); a.startNow(); // regardless if its start() or startnNow() it will work in most of the cases but not 100% reliable I actually can see in debug Log when its late, happens after few more clicks
Then in myListener.onAnimationEnd(Animation a):buttons[location].setImageResource(R.drawable.standard_button);
Seems there is a rule that the every 4th or 5th animation does not start ...
Is it possible in Android to get a callback when a Frame Animation (AnimationDrawable) has completed playing its frame sequence? I know when a Tween Animation has completed, it calls onAnimationEnd(), but is there something similar for frame by frame animations?
View 1 Replies View RelatedMy 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...

View 2 Replies View RelatedI'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.

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.
View 2 Replies View RelatedI have a list Activity 4 which i have extended the BaseAdapter and the getview looks like this.
public View getView(int position, View convertView, ViewGroup parent) {
View row=null;
for(int i=0;i<10; {
row = convertView;
if(row==null) {
LayoutInflater inflater = mContext.getLayoutInflater();
row = inflater.inflate(R.layout.parsed,null); }
TextView id = (TextView)row.findViewById(R.id.id);
id.setText(idvector.elementAt(position));
TextView photo = (TextView)row.findViewById(R.id.photo);....
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?
In one of my projects I've got a ListView with hundreds of elements. But when scrolling through this list I get the following error:
CODE:.....................
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 some questions. Can anyone give me some suggestions and I will appreciate about that. 1.There are 3 files : Android.mk, gps.cpp and gps_qemu.c in hardware/ libhardware_legacy/gps. What is the functionality about the 3 files in directory gps. Should I modify the 3 files to implement GPS. In this web site http://www.netmite.com/android/mydroid/cupcake/development/pdk/docs/g..., it shows that anyone that want to integate GPS with Android should create a shared library named libgps.so refer to gps.h. My question is how to create a shared library libgps.so.If the libgps.so is created, where can I find it. What is the relation between libgps.so and libhardware_legacy.so. 3.How to test GPS if gps is implemented successfully. I know there is a gpstest tool in Android but I don't know how to use it. Can someone tell me the detail about gpstest tool provided by Android.
View 5 Replies View RelatedSay I want to define that an URI such as: myapp://path/to/what/i/want?d=This%20is%20a%20test must be handled by my own application, or service. Notice that the schema is "myapp" and not "http", or "ftp". That is precisely what I intend: to define my own URI schema globally for the Android OS. Is this possible? This is somewhat analogous to what some programs already do on, e.g., Windows systems, such as Skype (skype://) or any torrent downloader program (torrent://).

View 1 Replies View RelatedLet's say I randomly generate a number 0 to 100. Where 0 is really cold and 100 is red hot. Wen the number hits, it would show an image bar (kind of like a % finished bar) that shows in the image what # you hit.
So it would kind of be like a progress bar from 0 to 100, and whatever # they hit it shows in the image of the bar in an imageview?

I would like to implement a new LocationProvider. In this case, one that uses OpenCellID.org. I figured the pattern wou be quite similar to providing an AccountAuthenticator but was stunned that I could not find any documentation on this.
Looking at the source http://www.netmite.com/android/mydroid/frameworks/base/location/java/... all the relevant code seems to be in a service providing the ILocationManager.aidl -interface that I cannot navigate to or find using Goole Code Search.
Is it supported to provide your own LocationProvider at all? If so, what do I have to do to acomplish this?

View 2 Replies View RelatedI'm brand new to android and developing in general. I'm using android's SDK with eclipse Galileo. I've followed several tutorials to create different layouts. I've even learned recently how to use radio buttons and verify which ones were selected. Now I need to create a service that downloads and updates an xml file within the application. I've tried to locate a simple tutorial for services on Google's developer site but so far, so bad. If they exist could somebody point me in the right direction?
On the other hand, I've been told Google's tutorials are a little out dated. Is that true? If so, are there any other tutorials that would hand-hold (and possibly over-explain) how to use a service to a true newbie for free (like google)?
