I have 2 questions about android TrackBall Event. I appreciate if you can help me with them:Can I detect the speed of TrackBall event? like in Fling, I can detect a 'big' fling vs a 'small' fling. Can I fling via the track ball?Why TrackBall Event always follow by Key left/right events? To me, they seem duplicate.

View 10 Replies View RelatedI've been searching around recently for a widget/app that'd allow me to input events and either pop up on my front screen reminding me (The day of/Before.. or whatever) or that I could have at the top of my following screen as the widget and have had no luck.
I'd like this to remind me of certain events that can go about slipping my mind (Student loans due on this day.. Flight leaving at this/that time) Or the general factor that there are a multitude of things to do and it's nice to stay organized.
So im just getting started with android development and i found my first head scratcher. I have an app that when opened makes a on going event notification. Then if i hit the home button the app falls from view and when i attempt to bring it back via clicking on the ongoing event notification its like opening a whole new app, then when i hit the back button the ongoing even goes away and it returns me to the original app window. How do i get the notification to take me to the original rather then opening a new instance.

View 2 Replies View RelatedIm working on a small application to try out an idea that I have. The idea is to periodically update the UI when event of some sort occurs. In the demo I've created, I'm updating a ProgressDialog every 2 seconds for 15 turns. The problem I am having, which I don't quite understand is that when an event is handled, I send a message to the handler which is supposed to update the message in the ProgressDialog. When this happens however, I get an exception which states that I can't update the UI from that thread.Am I missing something? The logic makes sense to me and it looks like everything should work, I'm using a handler to update the UI like it is recommended.

Similar to how blackberry's handle calendar events..
After buying my lovely HTC Desire two weeks ago I'm now trying to start using my phone as an organizer/agenda.
Unfortunatly I really have sucky memory (hence I need to use the agenda from my phone) and thus I actually have NO idea what date it is today and everytime I goto the add event dialog I forget to look at the calendar what day it curently is (let alone tomorrow!).
Since the default app only has those anoying slider/slotbars to pick the date for an event... I keep placing events on the wrong date! :@
I've been trying to find a replacement app but the only two I've found so far (Jorte and Gemini) have the same anoying dialog to add an event!
All the other 'apps' I find when looking for android calendar apps are widget-only!!
Anyone knows a way to get a datepicker or something like that into the calendar app or a different app?
Maybe at least display the name of the day when creating a new event?
My app wants to whisk the user to the "create new event" composition window of his Calendar app, initializing begin time, end time, title and description text for the event, but then leaving him able to see these values and optionally alter them before saving (or discarding) the event using the oridinary means available to him from within the Calendar's create new event activity.
HOWEVER...
My code which works dandy on my own dev phone (indeed, on any phone running stock Android Calendar to the bone) fails on the HTC Hero. The issue is that the Hero has been "improved" by use of a non- standard Calendar app and my means of doing this is therefore failing.
I wonder if someone can outline a more generic means I can use to say "tell whatever the user's preferred Calendar app is to create a new event, seeding the effort with these key/value pairs".
Here is my present code:
CODE:...................
I want to change how a gallery looks like. I want to add 2 jogs at each side, so looks like this:
http://omploader.org/vNHc2Yw/device.png
First approach was to add the "jogs" to the ImageAdapter (at the beginning and at the end) for the Gallery. The Gallery will show the items as usual, but It will apply the custom background and also if you specify spacing, you will get an ugly gallery. Also, I want the jog not to be centered as the others images. Then, I decided to download the whole api and modify the Gallery source in a way so to handle specially the first item and the last item of the adapter. But, I don't know how to compile the api alone. The Makefile in the root project will build 6gb of the whole android platform. If someone can explain me how to build just the API, I will be grateful.
The other approach was to compose Views. I thought to add ImageView's to the left and right corner and to be scrolled when needed, but when the Gallery capture the events I can't forward it to the holder of the ImageViews. So, I extend Gallery, and I override onScroll() like this:
super.onScroll(e1,e2,distanceX,distanceY); return false;
and also onTouchEvent() like this:
super.onTouchEvent(event); return false;
But unfortunately when I return false wihtin onTouchEvent() the Gallery does not scroll.
So, main questions are:
1) How can I compile the modified API to generete a MyGallery.class to be added to android.jar? If I modify the source code of Gallery.java I can manage the fill of the Gallery for the specific items I want (I already read the source code).
2) In other approach, Is it possible to handle one event by 2 widgets? If so, I could overlap the Gallery above a jog. The Gallery will scroll as he knows, and I will scroll as I want.
3) If those approachs are bad, what will you recommend ?
I don't get why the Gallery does not have this nice feature I want to implement, kind of: setBorders(left, right) and etc. The problem on extending Gallery, is that when you add a View (for instance, the "jog"), you specify a position. Gallery fills the gallery getting the Views of it container with: getChildAt(0) and getChildAt(numChildren -1) when filling to right and left, respectively. Then, it gathers the 'unseen' Views from the Adapter. So the added view (the 'jog') will be scrolled by Gallery, but when the view is no longer visible, the Gallery itself has no way to get back that view, as it's not in the Adapter.
I want to keep launching my app and stress test two scenarios: launch it and press BACK key launch it and press MENU key I can launch from adb using "am" command. But how can I send a BACK or MENU key using adb. I want to do thousands of rounds of testing so I don't want to do it manually.

View 2 Replies View RelatedI have tried all day to capture a trackball event in a View. Basically I want to use the trackball to move a Sprite in a 2D game left and right. The onTouchEvent works perfectly well in the View to move the Sprite with my finger but it would be nicer and cleaner to use the trackball.Can anyone provide me with a simple example that uses the trackball to move something in a View in a 2D type game world (not a menu or UI type of example)? Or can someone explain what I'm not doing. Thanks so much for any help you can give me.
View 3 Replies View RelatedI want to move an image around the screen according to the trackball movement. I am able to capture the movements using the onTrackballEvent method. But this is being called for very small float values (I believe for each rotation?) of the trackball.Now as X and Y positions of views should be integers when specifying with LayoutParams, it makes no sense to move the view with every rotation. Instead I want to move the view only after the user stops rotating the trackball.Is there any method by which we can get whether the user stopped using the trackball or not?
