Android : Trigger An Action When User Has Hit Enter?
Nov 17, 2010
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've been doing alot with the initialization routines in android just lately .
For all my efforts I have been unable to get the device-added init action trigger to fire,
Just to be clear this is set in init.rc and looks like the following,
Code:
on device-added-/dev/compass
start akmd
The above is taken from the init readme file which contains an example init.rc at the bottom
I did some further research and a quick search of the AOSP code. This revealed that the functionality is yet to be implemented. which obviously explains why the trigger wasn't being fired . The device-removed and service-exited triggers are also missing.

I would like to know if it's possible to update a third party application without user action. By 3rd party, I mean an application not located on the Android Market but rather on a specific website.

I looked around and although there are many related questions I didn't see one that answers my exact question:
I would like to create an app that runs in the background that provides the exact same functionality as the hard coded 'Back' button in all cases.
The reason? I (for example) have a Droid X, and it is BIG. it makes it extremely hard to use one-handed and having a swipe gesture function as a back button (like in Palm Pre for example) would greatly increase the ease of use.
as far as I'm concerned the app could just be one simple class that contains:
1) a listener for the 'back' swipe
2) a call to the physical hard button itself
Is this possible? are there built in APIs for the hard coded buttons that would allow me to call them without actually pressing them?
Again - I'm not interested in overriding the button, I'm interested in making a software call to it - or failing that, in emulating it's behavior in any and all states and other apps!
Please forgive the naivete of this post. I am a very novice programmer and really I just want to know whether this is possible before I start to devote myself to trying to build it.

I'm curious as to whether anyone else is having this problem or if it's just me. I just updated to the latest Tapatalk 1.8.0 and find I can't login to the forum I use it with (no, not this one). When I enter my user name and password it just bounces back to the login screen with no complaint.

I thought that Action was preeminent during intent resolution and if the intent had the same action as the intent filter, it would be considered a match regardless of data, if the filter did not specify anything. So I was very surprised to find that supplying action+data where filter had only action, causes it to fail. In the code below, if you comment out line 47 so that data is *not* sent, only then it resolves correctly. To get it to work with the data (an id that is simply a String), what mime type should I specify in the intent filter?

Can 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?

Can 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

I 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
android:id="@+id/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?

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 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?

I have a website designed for the android browser using jquery/jqtouch. As a part of it, i have a map page that loads. In the process of displaying my data, I found that some of my customer's addresses, when clicked kick of the google app map, with the data sent to it. It also seems to load and run a ton faster (as well as having all the benefits of navigation, etc).
So I've searched and searched, but am unable to "emulate" that built in function of kicking off the address. I've tried links with geo: and maps:, etc, but to none will open the installed app. Yet, just having a <li></li> item with an address, the browser will detect a "proper" address and open the app.
I don't care if i have to kick it off with javascript, or a href, it just has to be embedded in the html.
