Android :: Generic Adapter
Jul 29, 2009
Generic android.widget.Adapter iface has getCount() method which tells e.g. ListView how many items adapter has. what if my Adapter's data source cannot tell me it's size and has only method Object getItem(int position) returning e.g. null when there is no item for that position? in other words i can get some object at given position but don't know maximum value for position so, is it possible to create Adapter not knowing apriori its size?

An OnItemClickListener for a ListView has the following method:
CODE:.......
I'd like to have the adapter behind the ListView refresh, and I believe this is done through the use of:
CODE:.........
How do I use the parent parameter in the onItemClick method to do this? So far I've tried:
CODE:.................
This throws an error because the object returned is of class HeaderViewListAdapter, which for reasons unknown isn't a subclass of BaseAdapter.

When I try to compile to following code, I get two errors:
Description Resource Path Location Type
Syntax error on token "void", invalid Expression AsyncTask.java /AsyncTask Project/src/org/me/asynctask line 19 Java Problem
Description Resource Path Location Type
The type AsyncTask is not generic; it cannot be parameterized with arguments AsyncTask.java /AsyncTask Project/src/org/me/asynctask line 25 Java Problem
CODE:............
Obviously AsyncTask IS a generic (http://developer.android.com/reference/android/os/AsyncTask.html#execute so why do i get those errors?

Does anyone know where I can find a generic image of Android 2.1? I have a Commtiva Z71 a.k.a Cincinnati Bell Blaze (which runs on Qualcomm MSM7227, 600 MHz) and no one has released instructions on how to root it or do really anything fun with it yet.

Is there a way to get/set a generic device name ? My app will offer the user an option to use the same app on several devices and they will be aware of each other through server. 1) Is there anything in the APIs to allow me to fetch some kind of friendly device name (cannot be OS/model since user might have the same on both devices) ? 2) AFAICT the only option is to use Bluetooth name but how can I fetch my device name in code?(and it's a nag do explain the user to use bluetooth just to set the name of the device)

The purpose of this tutorial is to change the generic windows icon of your G1 to an Android icon. What icon you ask? The generic removable disk icon given to your G1 when you plug it in to your PC. i thought it would be fun to create one that differentiates it from the rest. So here we go!
1. First of all we are going to download the pack ive created for you here.
2. Second we are going to rename the drive to Android G1 like i have on this image.
3. Third we are simply going to unpack the files you downloaded using an application like, WinRAR or 7-Zip. WinRAR offers you a 30day trial and 7-Zip is an open source freeware product. Choose one that fits you.
4. Now we are simply going to drag it into the root of the drive. Seeing since mine is the "K:/" drive, im going to place it in there. Once that is done, highlight both icons and choose properties and check off the "Hidden" attribute so that you don't accidentally delete them.
5. You're all set! Enjoy your new icon! Im going to be making a Vista version for all you people that like high quality icons. Stay tuned!

There's seemingly no way to launch the calendar app in a generic way. I've written a widget which allows you to launch the calendar. I use the following Intent:
Intent intent = new Intent(Intent.ACTION_VIEW); intent.setClassName("com.android.calendar", "com.android.calendar.LaunchActivity"); startActivity(i);
However, this doesn't work on the Hero because HTC has apparently replaced the calendar in their Sense UI. I'm looking for a "standard" way to reach the calendar. I'd like for something like this to be standardized:
Intent i = new Intent(Intent.ACTION_VIEW); i.setType("text/calendar"); startActivity(i);
Does anyone think it would be worth trying to add this to the source? It seems like there is a missing chunk of standards around calendar events and/or iCal / vCal support. Does anyone know why?

I have a Samsung Moment and it is connected to my iMac for file sharing. By default when you connect, you get a generic drive icon with the title NO NAME.
Does anyone know of a way to change the generic icon? Usually you can do this with the 'get info' feature on the Mac, but once I did this, I just get a blank ICO icon file.
Just thought it would be cooler to use the Android robot icon instead whenever I connect my phone.

Within a public class that doesn't extend any other class I'm doing some evaluation stuff and I would like to return a Dialog if something needs to be communicated to the user.
I'm using an AsyncTask to run a method of an instance of this class from the main ui:
CODE:.........
Now, the public Dialog start() method of OnlineActivities.java creates a dialog using the Context that was assigned via it's parameter.
When the Dialog is returned to onPostExecute I receive the following exception
CODE:......................
I suppose I cannot use the context like this. But what would be the alternative? How can I outsource some basic stuff I always need to do, even some general Dialogs? Do I need to use custom intents instead?

Currently porting an iPhone application to Android. I've encountered an issue that I haven't been able to overcome. On the iPhone, translating your text is trivial. Put all your strings/text in Localizable.strings in the format: "sentence to translate" = "sentence translated" The original string can contain any characters of any type. So, what are the restrictions in the name of a resource on Android. Or is there a way to circumvent it and easily replace one string with another. I'd like to keep the original dictionary of text I was using on the iPhone to keep things simple and not introduce any unnecessary errors.

I want to display the same options menu on all of my application's activities. I created a generic Activity that implements the menu, and all my further activies extend it. The problem: when I need to extend other specific activities, like ListActivity and MapActivity, I can't figure out how to extend the generic activity and add the List or Map behaviour to the new class. To deal with the issue I had to create three different generic activities, each extending Activity, ListActivity and MapActivity.I've tried creating an abstract activity but it doesn't work, I would need to extend two classes at the same time. I could try interfaces but since I can't implement methods, I would have to paste the menu implementation all over the second-level classes, right?

I tried possibly ever option on le google (and some here) but to no avail. Installed every program suggested on the net (unlockRoot, onclickroot, etc etc) as well as the necessary programs (SDK, ADB drivers etc) but it just seems it is impossible. So I turn my plead towards you, after two full days of struggling with this stupid thing.
How can I root my 4.0.3 ICS generic tablet?

I'm having a problem with Handcent on my Droid. It seems like only one or two of my contact's pictures have carried over to Handcent, so whenever I get a new message or I look in the app, it just has the generic picture with the question mark.

I currently have a HTC Hero (Android 1.5) running on the Meteor network in the Republic of Ireland. From what I can tell the phone is not rooted (Titanium says so anyway).
The build number on the phone is: 2.73.405.66
I understand that in order to root my Hero I need to downgrade to 2.73.405.5 - can anyone point me to a generic 2.73.405.5 ROM ?

I have a class which extends AsyncTask, which is intended to serve as a generic task manager class for my application. The strange behavior is that the progress dialog shows up, but is never dismissed. I am sure that onPostExecute() gets called for every task instance, as any Log.d("","") statements fire if placed in here, even the Toast messages show up from within this method, but I am not able to dismiss the static dialog. I understand that AsyncTask(s) have access to UI thread at only 2 places [onPreExecute() and onPostExecute()], so I think trying to dismiss the dialog in runOnUiThread() is unnecessary. All calls to executeTask() are made from different onCreate() methods of different activities that need to fetch some data over network before populating some of their UI elements, and I always pass the current activity's context to the tasks. As I do not switch activities until after the related tasks are completed, I believe the activity context objects are still valid (am I wrong to have assumed this???) I have never found any of them to be null while debugging.
Could this be a timing issue? I have also observed that most of the times DDMS shows all tasks get completed before the activity is displayed. If I use new Handler().postDelayed(runnable_which_calls_these_tasks,10); in the onCreate(), and add delaying code in foo_X(), the activities are displayed without any delay, but the dialog will just not dismiss(). I have read through quite a number of articles on this issue but am still not able to figure out exactly where am I going wrong. I do not want to define each task as private inner class Task1 extends AsyncTask<> in all of my activity classes and I would not want to (unless this is the only solution) load my application object with all activity references either as mentioned in this discussion: Is AsyncTask really massively flawed or am I just missing something?. I have spent a week on this and am absolutely clueless :( It would be great if someone can guide me, and let me know what am I missing. Following is the class definition: [I've removed some irrelevant application specific code for clarity]
public class NetworkTask extends AsyncTask<Void, Integer, Boolean> {
private Context UIcontext;
private int operationType;
private static ProgressDialog dialog;
private static int taskCount;
private NetworkTask(int operationType Context context){ this.UIcontext = context;
this.operationType = operationType;
if (taskCount++ == 0) dialog = ProgressDialog.show(context,"","Loading...");
}
public static Boolean executeTask(int operationType, Context context) { return new NetworkTask(operationType, context).execute().get();
} @Override protected void onPreExecute(){ super.onPreExecute();
if (taskCount == 1) dialog.show();
} @Override protected Boolean doInBackground(Void... arg0) { switch(operationType){ case TYPE_1: foo1();
break; case TYPE_2: foo2(); break;
case TYPE_3 foo3(); break; case TYPE_4: foo4(); break;
} @Override protected void onPostExecute(Boolean result) { super.onPostExecute(result);
taskCount--;
if (dialog.isShowing() && taskCount == 0){ dialog.dismiss();
}else { Toast.makeText(UIcontext, "Task#"+ operationType+", m done, but there are "+taskCount+" more", 5).show();
} } }

My build version is 1.1561.10.10 CL1551070 - so my question here is where can I find the latest Generic HTC ROM to root my Desire to?
I'm currently on the Orange UK branded, though i'm aware there's no backup ROM for orange as of yet i still want to go through with the generic root. I got the guide and what not.

I love my new Desire! It has prompted six people in my office to purchase it, but what I have found to be annoying is that I have lost the generic HTC browser. This happened when I installed Dolphin.
I now have Opera 5 Mini Beta and that Orange Browser labelled "Internet" but not the stock one. I want it back as its great at rendering pages etc..

I bought a generic car charger for my Droid. My thought was something along the lines of "a micro USB charger is a micro USB charger" and clearly I was wrong.
I noticed that after an hour on the charger while i was using GPS, 3G and Bluetooth, that the charge on my phone had actually dropped by about 10%. At best, the generic charger only slowed the drain from the battery. I replaced it with a Rocketfish charger from Best Buy and, while charging was painfully slow, it did charge.
Maybe it was the brand of charger and maybe my charger was faulty but I thought I'd throw this out there for anyone who is going to grab one.

I forget my original charger at home so i got a new one from at&t (didn't find t-mobile), generic one, with the same connector and the guy from the store said it will work fine with captivate (that should be the same as the Vibrant). when i tried to use it, it charged my phone but the whole interface was laggy and didn't get half of my touch pressing (the other half did something else like pressing the wrong spot).
anyway i thought its a bad charger so i get a new one from RadioShack... that do the SAME problem.
then i tried some electric shop that told me theres a difference between this chargers and i need to get the Palm Pre charger and not Motorola/BlackBerry, but still both of them did the same problem (again, all of this stores got only third-party "generic" chargers and not originals). anyway i got home and charged with the original usb wall adapter and usb cable that came in the box.

I am considering buying a 16gb or 32 gb micro SD card to store some movies and music on my Incredible (which I receive later today, I can't wait). What are the drawbacks to buying a really cheap one off of ebay? I've noticed you can get them for about $10 with shipping. Is it just that the transfer will be very slow?
