I'm wondering if someone know a snippet of code that would implement a joystick behavior. I did a 4 orientation button widget but it's really not user friendly for my game.

I recently decided to try out making my app tentatively "GoogleTV ready" by ensuring a user can do everything without ever entering Touch mode. For most stuff it is pretty straight forward, but I'm scratching my head at MapView/ItemizedOverlay: The docs appear to indicate that onTap(index) should do the trick, but it seems not to work the way I expect it to. "onTap ... This could be from a touchscreen tap on an onscreen Item, or from a trackball click on a centered, selected Item..."
Working around it using onTrackballEvent() and perhaps an onFocusChangeListener seems possible, but the documentation appears to indicate that this should not be needed for simple cases, right? I get the circle in the center and can move around with the D-pad/trackball, but when trying to select, hitTest() is not called and onTap(index) appears to be called with stale info. Anyone got a working code snippet? (Mark's NooYawk sadly doesn't work and googling came up with blanks apart from questions without answers).
I find this code useful and want to copy-paste it into my application which is licensed as public domain.
It is the Android blog, they often show useful code snippets. There is no way to contact the author, and the only license info I can see is "©2008 Google Inc. All rights reserved."
Should I:
Stop worrying and just copy-paste?
Reimplement it myself without looking?
Copy-paste and then make it look different?
Any better solution? ...
Is there a rule like "if shorter than 50 lines then no copyright applies" or something?
In my Android app, I have some data that needs to be synced daily but also needs to be updated every hour when a user is inside the app. I have already implemented a service that gets called from an alarm for the daily update. I'm having a problem with developing a strategy to do the hourly sync. I could use an hourly alarm too and fire the same intent, but since your app can be killed at any time, there would be no way to cancel it (and since they use the same Intent, doing a cancel would cancel ALL alarms including my daily sync, so that's probably not good). The other option is to use a Timer that's set when inside the app, and have that fire my Intent when inside the app. I'm assuming all Timers get canceled when an app is killed right? But my app consists of several activities and I want the timer to work across all activities, how do I do that? I dont want to duplicate code - we're already using a subclass for Activity and ListActivity.

Anybody done with this kind of coding?

View 17 Replies View RelatedI'm not sure if this is just an issue with my dinc, but the joystick is too sensitive - to the point of being unusable. Every time I try to navigate screens, lists, or text in a message or web site address it acts as if I've pushed it no matter how light I touch it or move my finger across it. Is anyone else having this issue?
View 8 Replies View RelatedI've had the Moment for about 1 1/2 months. At times, it seems as though the joystick is "stuck" - it moves the cursor all around (sort of like the center mouse on a laptop). Sometimes it will move around the screen, move from one screen to another, move the cursor when typing, etc... It makes the phone unusable. I've looked in a bunch of forums and haven't seen anyone else complain. I normally have to remove the battery and boot it back up and everything starts to work again. I had a zag on it, but removed it thinking it might be the problem (it wasn't). The Sprint store was zero help (it didn't happen while there). Is there a way to disable the joystick? I'm tempted to just take the phone apart and remove it.

Let me preface this by saying that I just unrooted my phone and downgraded from Froyo, so I'm not interesting in rooting again if that's the only solution that you have.Is there a setting to adjust the speed at which the cursor (in text boxes, emails, sms, etc) scrolls through each letter? It seems the fast I move my finger across it, the slower it moves, but the slower I move my finger the faster in moves. Is there a setting I can adjust? I compare this to choosing how fast the cursor on your PC moves when you move your mouse.

View 4 Replies View RelatedI have a joystick with 6 axes an 2 buttons. If I connect that joystick to my device (nexus 7) through an otg cable it gets recognized as HID device.
The two buttons are both mapped by android to ENTER and the X + Y axes to direction keys. So it is already possible to control some UI sections (ie app icon selection on launcher).
I added a key layout map in "/system/usr/keylayout/Vendor_046d_Product_c626.kl" to customize the two buttons. I was also able to remap and invert all 6 axes.
Code:
# left / right
axis 0x00 RX
# forth / back
axis 0x01 RY
[Code] .....
As you can see I mapped the two buttons to the volume controls, which works fine. Unfortunately I'm not able to figure out how to map axes to keystrokes. As the X + Y axes are mapped to direction keys, there must be a setting somewhere for this. I would like to use all 6 axes and map them to simple keystrokes.
Can I assign an app to the double click of optical joystick? (kinda like iPhone favorites). Also, is there a way to replace the default dialer app with another app? i.e. when I click "Phone" on the home screen, is there a way to bring up a different dialer app?

View 18 Replies View RelatedDoes anyone know how to set the notifications behavior on the EVO? Specifically with Google Talk? I would like the phone to beep at me only once when someone sends a google talk message, and then not ever again for the following messages until I unlock the phone's screen and reactivate the google talk app. I think it already works this way for email, but not for Gtalk. Can this be done? And, I already know that if I open up the chat session, the sounds shut off on successive messages. However I would like it to stop the beeping without opening the chat window.

View 4 Replies View RelatedI have a package with two activities
1. A main activity 2. A search activity
The search activity is invoked by a search suggestion provider in two possible ways
1. By clicking directly on a suggestion invoking the search activity through a VIEW action 2. By clicking on the explicit search icon invoking the activity through SEARCH action
If it is invoked through SEARCH I stay on the search activity and show some text to the user. Now when I click the back button I go back CORRECTLY to the home page.
ODD Behaviour: However if I came to the search activity through the VIEW, I invoke a browser activity and call finish() on the search activity. Now I have the browser in my view. If I now go back I would expect to go back to teh device home page. But from now where the "main activity" is showing up.
I see in the logcat a message from ActivityManager indicating
moveTaskToBack: 8
I have tried various flags to invoke the browser activity the tried flags include new task previous is top and I have also tried both a singleTop and otherwise with the SearchActivity as well. Same end result.
1. I want to know the behavior of activity for the cases where onStop and on Destroy were not called like low memory situations.
2. I was registered my handler in on Create() and unregistering in on Destroy, what is the behavior if other thread sends messages to the registrants after the activity was killed by android without calling on Destroy. I know that those handler were not removed by GC as they are still referring by the thread.
3. Also suggest me to handle the above situations.
I have a ListView set up in single-choice mode like this:
<ListView android:id="@id/android:list"android:layout_width="fill_parent"
android:layout_height="fill_parent" android:background="#ff444444" android:layout_weight="1"
android:drawSelectorOnTop="false" android:choiceMode="singleChoice" android:scrollbars="vertical"
android:headerDividersEnabled="true"/>
When I press my finger on a choice, the selection changes from white text on light gray to black text on orange. But as soon as I lift my finger, the selection reverts to the original state. I'd like that chosen row to remain in the black-text-on-orange mode when I lift my finger so that the user knows what was selected in the list (my onClickListener has captured the selected row, of course). Is there a way I can tell the ListView that I want this behavior or something similar so the user knows what item has been selected?
I have a TextView which is inside a LinearLayout which is in the child position of an ExpandableListView. Without assigning a color state selector to the text view, the following behavior is observed:Text unselected - text paints as white Text selected - text paints as black.If I add a color state selector with a call to text.setTextColor(R.color.textcolorstatelist) then the following behavior is observed:Text unselected - text paints as black Text selected - text paints as black.I tried two versions of textcolorstatelist.xml and both produced the results above.
View 9 Replies View RelatedI am using a handler inside my service to display notifications at a certain time using the Handler.postDelayed method. My application runs fine on the emulator just as expected satisfying all cases. But when I installed the same on my HTC Wildfire, it simply doesn't happen as anticipated. Notifications are displayed at a random manner after the scheduled time and some notifications even fail. I'm monitoring my service from the Applications > Running Services and still my service is active.
View 1 Replies View RelatedI am trying to add ringtones to the media/ringtones folder from my application. If the phone is connected via USB to a computer or mounted on my Mac, the ringtones do not show up in the SD Card, nor in the Ringtone settings.

I got two kind of lists on 4 different views. All lists are clickable and starts an activity to read the clicked record. One is just a listview populated from the DB and works fine. The second is also a listview populated from a DB but has a addHeaderView. This makes the list forget where it was when you return from the listview's intent. If I remove the addHeaderView(); it works fine. Why does AddHeaderView changes or even malfunctions ListView's behavior?
View 2 Replies View RelatedI changed my database schema on my application to include an additional column in one of the tables. I did this in the onUpgrade method in the DBHelper.
Then I tried exporting my signed application and reinstalling it using the 'adb install -r <app>.apk' command to try and 'simulate' an application upgrade, but onUpgrade never gets called.
Is there a command that I can use to try and duplicate the behavior of an application upgrade?
I have an audio player toolbar activity that has a corresponding layout file.
I need this player to show up at the bottom of another activity. I use a ViewStub and inflate the audio toolbar's layout file in the stub.
How do I access the buttons, etc on this inflated view and how do I set their behavior?
The docs on ViewStub did not mention anything about this (or maybe I totally overlooked something).
