Im looking for an event that I can use on the scrollView to be fired when the user has scrolled to the bottom. E.g my list of items should be extended with more items automatically.

Android supports an event onLongPress. The question I have is 'how long' (in milliseconds) is the 'press' to trigger the event?

View 2 Replies View RelatedI need a button to run a function while it is pressed down.Then run another function when the button is released.
I am trying:
btnDown.setOnTouchListener(new View.OnTouchListener() {
public boolean onTouch(View v, MotionEvent event) {
if(btnDown.isPressed()) {
displayDown.setBackgroundColor(Color.GREEN);
return false;
}
displayDown.setBackgroundColor(Color.RED);
return false;
}
});
I need to trigger an event when the button is released.
I find that there is a function onKeyShortCut in every View Component, but when I read the SDK document, I find that the function can only be trigger by the function setShortcut in menuitem component, is there any other way to trigger this event, for example, through send a keyEvent.
View 1 Replies View RelatedI have a problem with rendering a ScrollView. Essentially, the layout is fixed header and footer with a scrollview in the middle. The idea is that when the screen keyboard is activated for the content EditText the image can be scrolled if the height of the image is longer than the middle view.
In testing the layout, I've found that on my Android phone (Xperia X10 Android 1.6) there is a whole heap of padding added to the top and bottom of the ImageView.
How I can prevent this from happening.
CODE:....................
I must be overlooking something real simple here, but i think i'm trying to do something fairly basic.. Simply retain the scrollbar position of a ScrollView on orientation change...
Here is the code for my onSaveInstanceState and onRestoreInstanceState.. sView is the container for the ScrollView layout. Within my scrollview is a linearlayout with a lot of textviews.
CODE:............
If I set a Toast with the values of sViewX and sViewY on the Restore, the values are kept and correct.
I just tried to do a sView.scrollTo(0,150); in my onCreate.. just to see if that would open the activity at 150px down, and it didn't. I think my issue has to do with the .scrollTo method.
I want some of the goodies in a ListView, like being able to use a ListAdapter, and item selection, etc, but I don't want the ScrollView portion of it. I want to implement that part myself, in a different way (why or how I do this isn't really the point of this question, so please don't ask "why"). Is there a way to have a ListView that's not in a ScrollView or has the scrolling disabled?

My AVDs suddenly can't reach the internet. I'm testing using the browser of the AVD. I haven't changed anything that I think is related on my development machine and I can still reach the internet from the development machine. I'm sort of at a loss figuring out how to start debugging this. Is it possible that my ISP is blocking the AVD? Is there anything different about the HTTP traffic that originates on the AVD that my ISP might key on?

We just threw together a website showing some of the work we have done on the project so far, so if you are interested check it out at :
I have a activity B that is called by activity A, I want to debug the code in B. I have set the breakpoint, however the debug control never enters B.
CODE:................
When I debug in eclipse, although the class B is called from class A, the debbugger pointer never enters the new window, where I have placed a debug point in Class B. I am not able to take the pointer control to class B and stop at a specific point, which will help me verify certain variable values.
I have Asynch in a seperate class, and I need to change setText on some of the TextViews
How this possible? OR should I keep AsyncTask inside my Class?

I've been messing around with C2DM and have a nice little app working perfectly in the Emulator. I send a message from my app server to Google's C2DM servers, the message will arrive on the emulator and my app would respond appropriately.
My problem now is running the app on my smartphone (a Nexus One). The app runs fine and registers for C2DM with Google and then forwards it's rego ID to my application server. This is all working as expected. Problem is, when I send a message from my app server to the phone, my app never receives the message. After some investigation I found out
that the message reaches the phone, but the C2DM subsystem seems to be forwarding the message to the Google Talk app and not MY app.
Has anyone seen this behavior before? Can anyone give hints on what to look for to solve this? I was assuming that if the registration messages where forwarded to my app, then everything else should be as well.
How can I trigger the software keyboard and add listeners to it's keys?
View 2 Replies View RelatedCan someone clue me in on the name of the intent that triggers the haptic feedback when the user selects icons on the desktop, or when in Labyrinth the ball hits the wall. I thought it was vibrate ... but after playing with Labyrinth I am sure there is something else. In Labyrinth it feels as if the thump occurs relative to where the ball hits (but I am not sure if this is really the case or I am imagining it).
I asked about this before and thought I had figured it out myself (thought it might be a short burst of vibrate) but apparently not.
I want to expose a portion of my app with an intent that will only display a simple dialog box for system setting. The only way I currently know how to do this is to have an activity that accepts an intent. In the activity I don't use setContentView. I only create and show the dialog. The activity is finished after you press OK from the dialog.
This is kind of okay, but the activity shows as a black backdrop under the dialog, until you press OK which brings you back to the last application. I'd like to just be able to show the dialog on top of the calling Activity. Any idea on how this can be done? CAN it be done?

View 3 Replies View RelatedCan anyone give a hint if you know why there are some ACTIONS that do not trigger their associated receivers when they are registered in the manifest while they are received when they are register through registerReceiver() ? For instance, when I declare: <receiver android:name=".MyReceiver"> <intent-filter> <action android:name= "android.intent .action .NEW_ OUTGOING_CALL" /></intent-filter> </receiver> if the application is NOT running My Receiver is never invoked. But now, if I register the intent from inside a service, MyReceiver is invoked properly
View 2 Replies View RelatedI have a simple overlay for a Google Map: http://pastebin.com/Rg8miMSh and I add/remove items on it depending on the zoom level. After removing/adding I call populate on the overlay and invalidate on the map view. Everything works just fine, except 1 glitch: after an item was removed, if I tap its location onTap is still triggered and because the OverlayItem is not there anymore i get java.lang.ArrayIndexOutOfBoundsException in com.google.android.maps.ItemizedOverlay.maskHelper(ItemizedOverlay.java: 562) (full stack trace - http://pastebin.com/KThn4ZLE )
Anyone knows why this is happening or how to fix it? Initially i called clear and added all items all over again which didn't seems to cause this problem. However having many items this was becoming a performance issue. Adding/removing only the difference works much faster and I would like to keep this method.
I have a layout that looks like this (some attributes removed for brevity)
<RelativeLayout>
<ImageButton
android:id="@+id/button"
android:nextFocusRight="@+id/gridview"/>
<GridView

</RelativeLayout>
When I navigate using the DPAD from the button to the gridview, the OnItemSelectedListener is not fired. However a new layout pass is perform. Why is this ? Is this an android bug & my bug?
If (in Android) I have an EditText box, how can I trigger an event when the user has finished entering data and hits return/Next?
I have tried using the code below but it seems to have no effect. I also get an 'The method onEditorAction(EditText, int, KeyEvent) from the type new extView.OnEditorActionListener(){} is never used locally' error.
myEditText.setOnEditorActionListener(new EditText.OnEditorActionListener() {
public boolean onEditorAction(EditText v, int actionId, KeyEvent event) {
if (actionId == EditorInfo.IME_ACTION_NEXT)}
I want to show the softkeyboard, but it does not work. Here is my code...
When i touch the screen, the softkeyboard does not appear, but the alertDialog "edit text" appears, which appears on normal edittexts when you long touch them.
This additional code in the onCreate has no affection:
InputMethodManager input = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
input.showSoftInput(myTextView, 0);
I absolutely love the Android OS and even Sense but the dimensions on this phone is killing me. With the iphone I can have the phone in the middle of my palm and be able to reach the power button. Not so with EVO as I have to slide my hand to the side to reach the power button and slide it again to reach the swipe to unlock. Kinda sucks as I wanted to really keep this phone even with the screen coming up issue everyone is having.
According to my golf grip measurements I have standard man's hands, so is people reaching the button and swiping without having to slide there hands?
I am rendering an EditText as one element of a list-style AlertDialog (which is backed by the default ListView implementation). I sort of expected that this circumstance would not change the behavior of EditText, but it does: a click on the EditText does not spawn the soft keyboard anymore.
After an hour of messing around with focus settings and click handlers I got fed up and debugged into InputMethodManager.showSoftInput(), and found this:
CODE:....................
The problem here is that mServedView is the ListView that's backing the dialog, while view is the EditText, and ListView.checkInputConnectionProxy() does simply return false in the default implementation of ListView (to be overridden by subclasses).
Worse, I couldn't find a way to set a custom ListView which allows proxying IME reuqests; AlertDialog.Builder.setView() accepts a custom ListView, but this is not the ListView that InputMethodManager sees.

I have a requirement wherein I need a list of all the contacts that are edited/changed.
As per the Android documentation,
_SYNC_DIRTY
will be set every time a contact is edited. But, there seems to be a bug in this, which makes this always set to 1 (no matter what), even is we explicitly set it to 0.
So, I was wondering if I can create a SQLite TRIGGER on the contacts database. Such that, everytime a contact is edited, the edited contact id is populated into a different table which I can read later from my application.
I tried this...
CREATE TRIGGER IF NOT EXISTS updated_contacts UPDATE ON 'contacts.db'.phones
BEGIN
INSERT INTO updated_table SET updated_id=old.person;
END;
But a few problems here...
1) 'phones' is a table in the contacts database. but, I am not sure about the name of the contacts database (here I have assumed it to be 'contacts.db').
2) updated_table is a table on a different database 'mydatabase.db' that I have created from my application. and, I am not sure if I can set TRIGGERS across different databases.
All this in Android 1.6 Also, I am not sure about the permission to access native contacts database on Android.
Is there any other way of achieving this.
I am trying to build an app on my wife's phone that pranks her on April 01, April Fool's day of course. The app is going to change her background to look like the screen was cracked, the background is very convincing when I try it on my Droid (I was pranked similarly).
Anyway, digging into how this would work, I think its quite the process, however, I may be looking too far into this. I started diving into setting an alarm, however, I am confused about a couple things:
Would it be necessary for my wife's phone to load this prank application in the background each time she reboots her phone? I am assuming yes, as I believe this prank application would most likely invoke a broadcast receiver to "listen" for April 01, 2011?
If the application doesn't need to load each time in the background, what facilitates Android alerting my application and firing it when April 01, 2011 comes around?
I hope that makes any sense, basically, I want to ensure this application runs on April 01, 2011 even if my wife's phone crashes or reboots.
What would be the most straightforward method of making this work? I apologize if I don't understand broadcast receivers properly, this is quite the new concept which I am not use to. The Service and Broadcast Receiver functionality is native to Android and not any other language, no?
