Need some information on Gestures. How does android treat Operations like Fling which are at device level? Are they treated as Gestures? I am not able to see any gesture listner code in Launcher (Home screen ) application. If i want to change ( add/remove/modify ) the behaviour of Fling operations where i should start looking in the android code base?

WebView can scroll on both axis. That makes it hard to integrate with the 1.6 gestures. At the same time a WebView is often used as the main and huge content area, so either there is a way to work with gestures properly or gestures can't be used in lots of places.
Did anybody do this and has recommendations on how to do that properly?
The main problem I see is that a scrolling in any direction can be interpreted as a gestures and which keeps the user from scrolling. And because this is an issue for any direction I can't workaround the problem with only using horizontal or vertical gestures.
The best solution I found so far is canceling the gesture when no new onGesture events occur for 200ms. And with the finger still on the screen the user can then scroll. But that sounds better than it is, as scrolling often requires to pull up the finger again, when the end of the screen is reached, and put it down again on the opposite side, to keep on scrolling. But then the next touch down needs to wait the delay again, which is not very intuitive and as it can lead to a gesture being executed this is even less cool.
I'm trying to scroll the ListView up/down actions by pressing a button, instead of using finger gesture. It looks like the super class AbsListView.onTouchEvent(MotionEvent ev) handles all the scrolling up/down motion and animation. So if I want to scroll the list by pressing a button, I don't really have a MotionEvent to pass onto onTouchEvent method for it to work. I tried ListView.scrollTo(x,y), it kind of works but the hidden part of the ListView is not rendered when shown on the screen. I am trying to re-draw the list by using: ListView.invalidate(), ListView.invalidateViews(), list.adapter.notifyDataSetChanged()
View 3 Replies View RelatedI have a love-hate relationship with my G1, with the inability to remap keys at the top of the list. I've looked high and low for information, going so far as to try to decipher pages like this:http://www.kandroid.org /android_pdk/keymaps_keyboard_input.html and even reading the android platform code on github. I don't see things like page_up and page_down defined in the android keymappings. And I suspect that the original scancodes are being assigned to touch gestures.Since the number keys don't have a third component could an enterprising developer map to the unused caps for missing keys? Not that it would be all that useful at this point but it would give someone a hook to build on. Or if that isn't possible, how about a virtual floating task bar kind of thing (maybe mostly transparent overlay?) that maps gestures like the swipe up/swipe down and more traditional arrows and enter type keys for the trackball? This isn't entirely a nit-picky kind of request. I have a medical condition that in the winter makes my fingertips extremely painful and the trackball hurts. I'm guessing that there weren't many arthritis sufferers on the Android development team, either. You would think that the touch screen should make things easier, not harder. Even my old, old Omnigo and HP100LX had utilities to remap keys, so it seems odd that there isn't some kind of app that could be developed. I think if I had enough time (which I don't) I might be able to eventually puzzle out a crude version of the task bar thing but I'd much rather pay a couple of dollars in the market.
View 2 Replies View RelatedWas wondering if there's any way to test Gestures (eg: Fling) on the Emulator.
I saw a project on google code that lets people simulate the accelerometer, but none of Gestures.
I would like to define an ImageView in Xml, and then listen to gestures which occur only on that ImageView. But, it appears that the constructor for GestureDector requires an Activity as a parameter, and then responds to gesture events on all components in that Activity. Is there any way to limit this such that events are only generated for gestures upon the pre-defined ImageView?

View 2 Replies View Related, you can swipe either from the top or the bottom to reveal the status- and navbar in Immersive Mode. Now would it be possible (preferably with Xposed) to disable one of these gestures? For example, you don't want to accidentally.
View 1 Replies View RelatedI am in love with the swipe gesture that exdialer has, that is swipe left for sms swipe right for call. But there are a lack of themes for exdialer and also it lacks contacts export and import, ability to set specific ringtone for one contact, etc. So what I wanna know is there any other dialer with the swipe gestures? Or is there anyway to bring it to the MIUI dialer?

I am struggling to find a way to determine if a valid network is available to an app. specifically, if there's a problem making a network connection, i would like to be determine if it's on the client (app) side, or a problem with the remote server. i happen to be attempting a URL connection (using http client) and the wide and varied possible exceptions don't seem like a reliable method. for example, when the network is down on the phone, i received "unknown host exception", which doesn't really indicate the root cause ... it's possible to get that exception with a valid network connection also. at other times i get other exceptions, such as socket exception. is there a way to ask the phone if it's network ready? the other option i thought was to ping a known good server to see if it responds ... with an IP address. kind of a heavy weight option and not foolproof.

Trying out Google Gestures (very cool app!) with SWII. I would like to dedicate one of my five SWII screens to this app as an opened app. In other words, I'd like to slide the main home page to the left and have the Google Gestures app open automatically. Sweeter Home is so configurable, I figure there must be a way. I just don't know what it is.

I have a database of notes and lists, with three association tables.
Basically, lists are parents of notes and other lists, and notes can be parents of other notes in a outline like hierarchy.
I am using this query to return all notes within a list as well as the number of subnotes each note has.
CODE:...................
This query works just fine, but it's overkill. I don't need to return count(n2.note_id) as Num_Subnotes because I'm only using that value to check if the note has ANY SUBNOTES AT ALL. Essentially it's a boolean value where 0 is false and > 0 is true.
It seems to me that counting all those records is a waste of time when I could just return 1 after finding the first matching value.
Is there a more efficient way to check if count(n2.note_id)>0 in the above query?

View 6 Replies View RelatedI am using a ContentProvider for caching results from a web-service query. It is an HTTP request and the response content is XML. Most of the data is cached, so I simply query the DB, if not found, request from webservice, insert in DB and requery the DB. Thus the response is always a Cursor from SQLiteDatabaseHelper.
I have one result set that is not stored in the DB and since it is 100% transient, but I would like to provide the appearance of it coming from the DB's Cursor. Is there an easy way to do this? For example, if I could project it onto the cursor with a cursor.setValue("string", objectValue) or some other existing implementation.
If not, I will either bypass the DB for this content result, or stuff it into a trivial table that is constantly reused.
