Android :: Programmatically Add Views To Views
Mar 7, 2010Let's say I have a LinearLayout, and I want to add a View to it, in my program from the Java code. What method is used for this? I'm not asking how it's done in XML, which I do know, but rather, how can I do something along the lines of (One View).add(Another View) Like one can do in Swing.

Sep 27, 2009I need a LinearLayout to contain 3 TableLayouts, and I can't get it to work. This is where the problem is I'm sure:
mTableLayout.addView(mLinearLayout, LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(nTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(oTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); mLinearLayout.addView(pTableLayout, LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
How Do I make this work? I can get it to work just find when I only add a single child view, but when I have multiple children view objects my app crashes.
Android :: Views And Their Child Views - How To Avoid The Ugly - Boxes - When Child Views In A View Has Another Color Than Background
Jan 6, 2010I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.
Android :: How Can Update The All The Views Inside A TabHost When Pressing On A ContextMenu Item From Within One Of The Views
Nov 16, 2010I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?
Android :: How To Make Use Of Views Defined In Layout XML File As Template To Create Views Programmatic Way

Android :: Switching Views With RadioButton And Saving Views In Bundle
Mar 6, 2010I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.

Jan 25, 2010Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Sep 3, 2010With 2.2, the old Calendar and Corporate Calendar have been merged into one. A slight problem for me is that I preferred keeping the two separate. I don't use the Google Calendar much myself, but I share calendars with bandmates so I can see their schedules for booking purposes. Now, when looking at my calendar to see my own work and social schedules, I have to wade through everyone else's scheduled events. I wouldn't mind continued access to others' schedules, but is there an easy way to separate my Google and Outlook calendars, and/or choose whose Google calendar events appear in my Droid calendar? Ideally there would be an easily accessible switch in the menu for whose calendar items I see. Lacking that, is there a way to turn others event on/off from my phone?

View 1 Replies View RelatedAndroid :: Managing Background Uploads
Oct 21, 2009In our app we're doing background photo uploads. The current implementation works using a combination of a Service and an AsyncTask. The former will trigger the latter, which will do the actual network I/O.
My question is: since the user can trigger many uploads in parallel, is this the correct implementation pattern? The problem is that I can never call Service.stopSelf() from an upload task when it finishes, because those tasks don't know anything about each other or the service that triggered them (because of the very nature of AsyncTask).
Do I even need a Service here at all? I always thought services were meant for long running background tasks, but their documentation clearly states that one must execute blocking operations in a separate thread. What's the purpose of Services then? You could just fork an AsyncTask from an Activity, it would make no difference at all.
Android :: Managing Activities From Service
Jun 1, 2010I have a service that listens to the serial port. According to data received from serial i switch between particular service states, and start particular activities on state transitions. I would like to accomplish it in following way: Let's assume there is one active Activity1 started from previous state, I call startActivity from service to start a new one Activity2, but I want to simulatenously destroy Activity1 when Activity2 gets on top of the stack. I tried to call finish() in Activity1.onStop but it seems not to work (Activity1.onDestroy() doesn't get called). I'd prefer to finish Activity1 after Activity2 gets on top in order to avoid blinking.
View 5 Replies View RelatedAndroid :: Managing Google ApiKeys
Apr 9, 2010I have a simple app that uses a Google MapView. Now in the layout file for my map activity, I created an apiKey for the debug keystore and use that. However when I want to deploy my app, I need a seperate apiKey for production (based on when I sign my application), correct?
What I'm wondering is how do people manage these two apiKeys. When developing I want to use the emulator and the debug apiKey, but when I'm deploying / doing some integration testing with my phone, I want to use the production apiKey. To me, it seems that I need to remember before compiling for production, to swap out the apiKeys in my layout file. A very error prone process given my bad memory.
Android :: Managing A Suite Of Applications
May 25, 2010I'm building a suite of applications, meaning that I have a single set of code that gets customized via a single change of an API key. This means that all of the applications have the same activities, same behaviors, but different icons, package names, and application names depending on the client I am building for.
Unfortunately, I haven't figured out a clean way to do this. Because the package name is what the Android Marketplace uses, I've been changing it to com.nilobject.productname.clientname. However, this changes the package for all of the activities to no longer be in the package of the application, since they live in "com.nilobject.productname." Additionally, the autogenerated "R" moves, so all of the references to R in com.nilobject.productname break.
I'm using Eclipse for development. Should I just refactor the activities with each build to be in the same package? Is there a system for this that I don't know about?
Android :: Managing Large Graphic Set
Sep 14, 2009I'm writing a game for a computer class that I'm currently taking for school. The game has a lot of graphics associated with it (mostly in .png format). There is too much data to simply include it as part of the 'res'. The way i'm currently doing it, is to store all of the graphics in a single zip file, in a folder on the SDCard, e.g., / sdcard/Game/PlayerImages.zip (or whatever). And then i'm using the ZipInputStream to read from those, then using the BitmapFactory to decode the stream and then draw them on the canvas. The problem that I'm having is that this method is terribly slow if I add a lot of images into the zip file. The best way I have found thus far is to name the .png files within the zip numerically, then use a for-loop to jump directly to a specific file, but this is still a very slow way of doing it. I would like to use a single file (like zip) to hold all of the files for several reasons. 1., i'm trying to use a file container so i can simply update graphic 4.png and then push it into the zip file (for example) from a server. 2., because android sees all image files on the sdcard when you open the gallery application. 3., easier to prevent data manipulation by doing an md5/sha-1 checksum on 1 zip file, rather than every time a file is opened if it weren't in a container.

Aug 12, 2010I am trying to create multiple notifications in my application. To identify each notification uniquely, i have given them an unique identificationId.
Problem: When a notification is selected, Tabs activity is called passing the intent. I want to access the unique notificationId of the notification that was selected in Tabs. I tried intent.putExtra() to save the notificationId in the intent. But, for multiple notifications its overwriting the notificationId and returns the latest one. I dont understand as to why this is happening and how can i avoid this overwriting of notificationId.
Android :: Managing Translations Updates
Nov 22, 2009How would one manage continuous updates to translations? I.e., when releasing a new version, you wouldn't want your translators having to manually copy and paste existing translations from the previous versions, or worse, re-translate everything. Even when for those languages that I translate myself I noticed that when introducing a new string, I basically need to update all the language-specific resources right away, or I will have trouble later on trying to come up with a list of everything that changed.
I'm familiar with gettext, where this problem is solved by basically being able to merge the diff between Original-V1 and Original-V2 into Translation V1.
Android :: Managing Touchdown Notifications
Feb 22, 2010Just installed the Touchdown on my Nexus One. Links with my firm's Exchange server perfectly and generally works as it should. HOWEVER, it is driving me crazy that I can't seem to manage notifications to the phone. That I want is to receive a notification prior to every appointment but to NOT receive a notification on the arrival of email.Can't find any setting to control notifications except "Enable Push" under Email, which would seem ideal except no matter how many times I uncheck "Enable Push," when I close and relaunch Touchdown, it is checked again (and I hear the email notification chimes going off constantly on the arrival of new emails). Also have issues understanding how sync with the server works, but this is a minor issue--the notifications are key for me, as I imagine they are with others who don't want their phones chiming constantly.
View 4 Replies View RelatedAndroid :: Managing Contacts With Lookup Key
Sep 20, 2010I'm currently writing a application that allows to save drafts (using android version >= 2.0). Each draft is connected to a contact via the ContactsContract.Contacts.LOOKUP_KEY. My problem is that if I change the name of my contact the lookup key changes also. Is that the way this works?
So for what do I need a lookup key? I thought that the lookup key does never change and now it changes anyway. I'm confused about that behavior. Can someone explain to me how to link permanently to a contact? Should I use IDs instead of the lookup key?

View 1 Replies View RelatedAndroid :: Managing Service Life Cycle Killed Due To Low Memory
Aug 25, 2009I have a service that polls for data. To indicate this to the user I have a persistent notification in the statusbar. In some cases when the device goes low on memory it destroys the service but OnDestroy is not called. Later when there is available memory OnCreate is called. Is this normal behavior? I had hoped that OnDestroy would be called to I could remove the notification in the statusbar. Now the user thinks that the service is still running, while it has been stopped by the OS.
In order to restart the polling how do I know that the OnCreate is really a restart event and not first time creation of the service? I thought about checking for the presence of the notification in the statusbar, but I couldn't find a API to check if a notification was showing or not. I have not tried "SetForeground" on the service, since the service isn't that important to the user, but maybe that would minimize the problem.

Aug 20, 2009I copied my music directly across from my computer to the memory card via a card reader, before putting the memory card into the phone. There were already some music tracks on the phone (not sure if they were from T-Mobile or HTC) so I put them in the same directory.
My albums are organised into folders, and the cover art for each album is stored in the album's folder as "folder.jpg" (which is based on how my desktop media player works). However, the music player app on the phone doesn't pick up the cover art.
Oddly, it did pick up on one album - this wasn't stored as "folder.jpg" but "leftrightleftright.jpg" (leftrightleftright is the name of the album). Trying this on another album doesn't seem to have done anything, though I admit I haven't searched for a "rescan memory card" option. Digging around the card, I've found the cover art for the songs that came with the phone in a different folder with numbered names.
What's the easiest way of sorting this out? I'd like to avoid using HTC software on my desktop if possible because a. I don't use Windows much and b. I don't want yet another program to handle my music!
