Android :: FastScrollEnabled - True - Is More To Getting Alphabetical Index?

Jan 28, 2010

I added android:fastScrollEnabled="true" to the xml description of my listview class. I was (probably mistakenly) expecting this to magically transform the scrolling of my really huge listview so that the thumb button and the indexes display on the right side.

Is there more to hooking up the listview so that the framework knows what its alphabetizing? I have custom defined cells.

Android :: Apply Alphabetical Filters On ListViewApply Alphabetical Filters On ListView

May 11, 2010

I need to create a list view that display same functionality as Contact App. I need to have a scroller through which i can traverse the list alphabetically. To achieve this i am following an example from API demos "com.example.android.apis.view.List1.java". It is using a textfilter. When i implement this functionality on a static list view => it is working fine. But when i try this on a dynamic listview=> it is not working.

Android :: Way To Organize Apps Menu Other Than Alphabetical Order?

Apr 25, 2010

Is there any way out there to organize your apps menu other than by alphabetical order? When you have a heaps of different apps and are always trying new ones like me it's not always easy to find that one that has a name that relates nothing to its function.Ideally I'd like some way of making categories in my app menu and and grouping all my utility icons, all my game icons etc.

Android :: True SAX Parser

Oct 12, 2010

I am trying to implement a robust RSS/Atom reader for android, and since Xerces won't compile I am struggling to find an alternative. I am using org.xmlpull.v1.sax2.Driver(), however this just wraps a DOM parser with SAX callbacks. Is there anything comparable to Xerces on Android?

Android :: True VOIP App

Feb 4, 2010

I got a mytouch 3g figuring it would handle voip like iphone and wm phones. But to my dismay, it appears there are no true VOIP apps for android that will allow me to call over wifi/3G from Germany.

I have read about sipdroid, truphone, skype lite, iscoot and others, but they all make a local call first, even to members of the same service -totally defeats the purpose. You'd be better off using a calling card!!

Anyway, just wondering if I am missing something. I got an android phone because I wanted to be part of something different, with great potential. I just didn't realize that it would be different in such a disadvantageous way...

Android :: Assets-Folder - Takes Always The First File By Alphabetical Order

Oct 17, 2010

I'm new in Java/Android programming, so please have patience with me.

I try to play a mp3 which is locate und the assets folder. I know there is another way with the /res/raw/ folder, but use the assets-folder because later I'll try to access the file by String.

This code works to play a mp3-file:

CODE:...............

Now the problem: In the same assets-folder is another mp3 file stored. Though I specify the name of the mp3 to use it take the one which comes first in alphabet. E.g. the other file is named "music.mp3" it plays this one. Renaming it to "worldmusic.mp3" it will play "song.mp3". Rerename "worldmusic.mp3" back to "music.mp3" it will take this mp3 again. Another test: Renaming "song.mp3" to something other so the application can find whats specify by the code above will result that no song is played. So this means the songname have to exist, although it take arbitrary the song first in alphabet.

I'm testing with the AVD emulator of eclipse. But I think the behaviour would be the same on a real device.

Android :: Used Uses Library Option True?

Also, when I set the build target without the Google Maps library, I get an error from my class that extends MapActivity.

Android :: 2.2 - SD Card File Directory List Now In Reverse Alphabetical Order?

Jul 24, 2010

I don't see anything about this change in the API differences report at http://developer.android.com/sdk/api_diff/8/changes.html. However when my Nexus One started running Android 2.2, the list of files created by the following code are now in reverse alphabetical order rather than alphabetical order (as they were with Android 2.1 and earlier, AFAIK):

CODE:.........

The line "Arrays.sort(fn);" revives the alphabetical order of the list, but sorts are computationally expensive and AFAIK the explicit call to Arrays.sort() was unnecessary prior to Android 2.2.

In addition to seeing this order change on the Nexus One, it can be confirmed on the emulator running level 7 and level 8 AVDs.

Android :: True VoIP Applications That Work

Sep 24, 2010

I have been looking around today and am trying to find a VoIP application that will actually work.

Let's say, what if I got my phone shut off from VZW, would there be a way to make VoIP calls over wifi? I have seen posts about using Google Voice in conjunction with other programs. Also, Nimbuzz? Anyone have a positive approach they have used for this?

I will be going out of the US for a while and will be getting my VZW account inactive for a while. I am looking for a way in which I'll be able to still use my Droid Incredible to make calls to the US using wifi. I'd even be willing to make calls just to Skype friends or Nimbuzz friends. I am hoping that someone else has found a way to accomplish this.

Android :: AsyncTask.cancel - True - Work

Apr 20, 2010

Cause it doesn't.I have a service running an Asynctask to do some work. I bind to it from an activity and call a cancel method. The service, in turn, calls AsyncTask.cancel(true);

AyncTask.cancel returns true. Nonetheless, the thread is still running happily and still doing the things in doInBackGround, sending notifications along the way.

There is no sign that it attempted to kill the thread. I am not using NDK calls or anything that I think should stop if from taking down the thread. What am I doing wrong? Or is this a known issue?

General :: True Android Lock Screen App?

Mar 14, 2012

I am coming from Windows Mobile 6.5 and was using PocketShield as my lock screen replacement. One thing that I am looking for in an android app is..

1. The ability to enter pin or pattern from the lock screen app while also displaying all the new features of the app. One screen to rule them all.

2. I now use WidgetLocker and it works great except that I have to enter the pattern after sliding my app. What is the point? Either I enter the pattern before I select the app from the home screen or after when sliding. I thought I was able to use the app on the slicker "outside" of pattern security.

Android :: Get Data Index Of Visible Item

Jan 4, 2010

I have an Android ListView created with a SimpleAdapter that has more items in it than fit in the screen. After the list has been scrolled, I need to get the position in the data model of the first visible item in the list.Basically I want a function like: listView.getChildAt(0).getPositionInDataModel().Adapter has a few functions in it, like getItemId(position) that looked useful; however, the SimpleAdapter implementation just returns the passed in position, not a row id like I'd hoped.A brute force solution would be to get the View at index 0, and compare it to the view for each item in the adapter.However, there doesn't seem to be an easy way to get the view for a particular position from the adapter.

Android :: Obtaining The Selected Index Of A Spinner

Mar 26, 2010

I want to obtain the index of the selected item in a spinner.

I am aware of the method getSelectedItem() which returns the item selected (which might be a String). But i want the index of the selected item.

Something equivalent to the setSelection(index) to set the selected item.

Of course I can get the selected item and compare it against the array of items to obtain the index, but I hope there is a better way of doing this.

Android : Index On Righthand Side For ListView?

Aug 23, 2010

Is it possible to have an index on the righthand side of a ListView? This is possible on the iPhone where running down the righthand side the alphabet is shown. Touching a letter on the alphabet brings one to the beginning of the items in the ListView that start with that letter.

Is there built-in code in Android for this functionality? Or is this something one would have to custom make?

Android : Use An Index Buffer With A Texture In OpenGL ES?

Sep 21, 2009

I'm using OpenGL ES to display some objects exported from Blender. Blender provides a list of vertices, a list of the face indices and a list of the 2d texture co-ordinates. Within Blender, and I believe generally in OpenGL, the texture co-ordinates map to each vertex described in the index array.

I suppose I have two questions:

I'm given to understand(see the "Applying Textures" section) that in OpenGL ES the texture co-ordinates map to the vertex buffer only, not the index buffer. Is this the case or is there a way of binding the texture co-ords to the index buffer instead?
If the above is true, is there anything to be gained from using an index buffer at all? After all to properly map the textures one will need to write out the vertex buffer with all the redundancy that would have been saved with the index buffer. Is there still a performance increase to be gained or are index buffers redundant for textured data?

Android :: Layout When Setting WindowIs Floating To True?

Mar 3, 2010

I've got a ListActivity using the Theme.Dialog theme and windowNoTitle set to true.

Unfortunately, when I do this, the header rows (just normal rows in the list but they look like sub headers) refuse to fill_parent width (instead, they wrap_content - the header text).

I noticed this was not a problem when using the Theme theme so I started narrowing everything down to what was causing the problem.

The answer: windowIsFloating. Theme.Dialog sets this to true, and if I override this to false, then the headers happily fill the parent width.

Is there a way around this (because I would like to set windowIsFloating to true)?

Android :: AllowTaskReparenting - True Will There Be A Single Instance Of The Activity

Oct 4, 2009

Before asking my doubt, let me clarify my understanding of allowTaskReparenting...

Suppose there exists a Task (say Task 1) and this task has an activity (say Activity 1) which wants to call my Activity (say Activity 2). Let my activity (activity 2) set the attribute allowTaskReparenting to true and let my activity have a specific taskAffinity(affinity1). When Activity1 calls my activity (activity2), my activity becomes part of the task1. But suppose another task (task2) is already present/created with the same taskAffinity as mine (affinity1) and an activity in that task (say activity3) tries to start my activity, my activity gets re- parented to task2.

Not sure if i was clear enough. If i were to rephrase my words...

If my activity has allowTaskReparenting set to true and an instance of my activity is already present in task1. If task2 with the same task affinity as my activity tries to start my activity, the EXISTING activity gets re-parented from task1 to task2.

My quesions:

(1) Is my understanding correct ?

(2) If I am correct then a single instance of my activity gets shifted from task1 to task2. So 2 activity objects of my activity are NOT created.

Android :: Achieve True Gapless Playback - Can't Seem To Improve

Jan 30, 2009

When using a mediaplayer to play back an audio file, you can set looping to true - that's not the issue here.

If looping is set to true, there's still an audible gap between the file finishing and then starting again.

How could I achieve true gapless playback? I've attempted using two instances of the same file, overriding oncomplete and onseek.. can't seem to improve the gap though.
