Android :: ProgressDialog Launched From OnItemClick Wait Until A Subsequent Thread's Run Method Returns To Show Itself

Jun 3, 2009

I have code in my activity's onCreate that sets an onItemClick listener. when it fires I try to show a ProgressDialog that will be up until a subsequent thread "Thread" does it's processing. Strangely to me, the progress dialog never shows until *after* the thread.run() processing is complete. Almost like it's blocking. Am I doing something wrong? this is true even if the run method of doCurrentLocation doesn't do anything.

Android :: Thread Loses Message After Wait And Notify

Apr 19, 2010

I have a problem handling messages in a Thread. My run-method looks like this The problem is that the run-method logs "id from message: null" though "message ID" has a value in the Log-statement. Why does the message "lose" it's data when being send to the thread? Has it something to do with the notify?

Android :: Way To Pause Method In Progress To Wait For Button Be Pressed?

Oct 25, 2010

Basically I have created a blackjack game (first using just java) and it falls under an infinite while loop (this is so that the deck data is kept and everything works well. So first it deals the cards and then it needs to wait for either the hit button (which is displayed) or the stand button (which is displayed) to be clicked. I initially did this with a while loop that would keep checking if buttons were hit (basically when a button was hit, a static int would change and stuff would occur). However this just causes the droid to freeze up (thus far anyway) and also not refresh. So please someone tell me there is some way I can have my method pause until a button is pressed? I also need to know the proper way to use invalidate() so that my textviews, pictureviews and such can be updated as the methods change them.

Android :: Updating Media List When Thread Complete

Feb 22, 2009

I am developing an application on the Android Platform for my music service (axcid.org). Haven't spent a huge amount of time in Java but could use a bit of help with this code: http://pastebin.com/m5300a4e6

Bit of bad practice in there I know but I haven't spent a ton of time developing Java apps. Anyways the problem:
if (!this.listLoaded) { //holdup this needs it's own thread
//Url load and parse time. // Now we can start a thread for the search
Thread thread = new Thread(this); thread.start();

I need update media list to be called when:
public void run() { // search
String URL = this.getIntent().getExtras().getString("searchurl");
sm.LoadResults(URL+"?android=1"); listLoaded = true; }
is done. However calling it from the thread will crash Android. Did many google searches but found nothing. How can I call updateMediaList when the thread is complete? (from the UI thread)

Android :: Droid Sqllite Taking Long Time To Complete / Options For Moving To Start Of Result Set?

Nov 2, 2010

I am working on building an android app but I'm nothing that my SQL operations are taking forever to complete

I have profiled the app to narrow it down to the act of moving the Cursor to the first row of the result set for a simple select query (only returning 1 row where I'm testing it to eliminate the size of the result set as a problem.

Are there any better options for moving to the start of the result set?

edit:

some code...

this runs 3 times and i have time it to approximately 2 secs for all the rest of the code or over a minute with this in.

i have also run just the rawQuery statement with out the move to first and its takes bout 18 secs so im looking at the worst part of the code first.

Android :: Moving Map Method

Jul 3, 2010

Is there any method that listens for map moves or zoom changes? I know there is a mapMoved() method in the map listener interface for the nutiteq map (I'm using google maps though) so I'm wondering if there is anything similar for google maps, or if not, if there is someway to listen for getMapCenter() changes.

Android :: Does WebView's LoadUrl Method Run On UI Thread

Aug 26, 2010

I am wondering how does webview load a particular URL. Does it create a new thread or load the URL in the same thread i.e. UI thread? The reason I am asking this is I am facing some weird wakeup lock issue when I launch an Activity from current Activity (in current Activity's onCreate method) which creates a WebView in it's onCreate method and loads a URL using loadUrl method. So when I am done with this activity and go back to the Activity which launched this is restarted because wakeup lock time was expired.I googled it and found out that if onCreate method of an Activity takes too long then this type of issue might occur. Have any of you faced this kind of issue involving a WebView? Any kind of help would be really appreciated.

Here is sample code.Activity A:

Android :: Is It Legal To Call Start Method Twice On Same Thread?

Aug 1, 2009

The following code leads to "java.lang.IllegalThreadStateException: Thread already started." the second time it is run through on the program This happens the second time updateUI.start() is called. I've stepped through it multiple times and the thread is called and completely runs to completion before hitting updateUI.start(). Calling updateUI.run() avoids the error but causes the thread to run in the UI thread (the calling thread, as mentioned in other posts on SO), which is not what I want. Can a Thread be started only once? If so than what do I do if I want to run the thread again? This particular thread is doing some calculation in the background, if I don't do it in the thread than it's done in the UI thread and the user has an unreasonably long wait.

Android :: Moving Cursor Adapter Cursor Creation To Background Thread

Mar 29, 2010

The structure of some of my activities is a simple ListView with a custom CursorAdapter. The cursor is created in onCreate() on the activity from a SQLite database. The problem is that querying the SQLite database can be quite slow at times with lots of data (and let's assume I've already optimized the sql query as much as possible). Because it occurs in onCreate() on the UI thread, I get ugly black screens when opening the activity, which sometimes turn into ANRs, on a slow phone like the G1. I want to load the cursor in a background and show "Loading.." on screen while doing so. I saw AsyncQueryHandler used extensively in the framework, but this seems a solution geared more towards Content Providers and not application-local SQLite databases. I then thought of trying to load the cursor in a background thread, but realize that this might be problematic, as the CursorAdapter should be instantiated in onCreate() and should take a cursor as a parameter. The latest thought I had was to instantiate an empty MatrixCursor in onCreate() and pass that to the cursor adapter, while kicking off a thread/TimerTask to query the database. Then, on database cursor load, call cursorAdapter.change Cursor to the properly filled cursor. This doesn't seem very elegant and seems quite wasteful, however.

Android :: Results From Alert Dialog Inline

Oct 10, 2010

Is there a way to get alert dialog results inline (like you can with most dialogs)? I want to determine what to do next inwith a dialog, but I can't figure out how to get the results back in the same method that I create the dialog from thus allowing me to continue in my logic flow.

void doStuff() { dlg = CreateDialog() dlg.show(); // shows the dialog and doesn't return till the dialog is dismissed

if dlg.getResults() == this) { doThis(); } else { doThat(); }

}

Android :: Custom Control Or Make Views Inline?

Dec 22, 2009

I have a requirement to create a control similar to UITabBar in iPhone, which is to be present on every activity of my application. UITabBar essentially is a battery of buttons exhibiting a TAB like behavior: every button maps to an activity. I have two solutions for this: 1. In the layout XML for every activity, I insert a <LinearLayout><Button/><Button/><Button/></LinearLayout> element. And then have a common listener class that will handle the button clicks. So, every activity will have an instance of this listener. 2. To create a custom Widget extending LinearLayout class, put all the buttons as its static members and let it handle the button clicks. Include this custom control in every screen.

Android : Way To Display Inline Images From Html In Droid TextView?

Given the following HTML: <p>This is text and this is an image <img src="http://www.example.com/image.jpg" />.</p> Is it possible to make the image render? When using this snippet: mContentText.setText(Html.fromHtml(text));, I get a cyan box with black borders, leading me to believe that a TextView has some idea of what an img tag is.

HTC Desire : How To Associate An App With Inline Controls On Headphones?

Jun 7, 2010

When I first got the Desire, the inline controls controled the functions of the HTC and Android music players, (not 3cubed for example.) Since installing Doubletwist music player, the controls now control Doubletwist only..? So now if im using the HTC player and press the > controll to pause the song, it starts playing the last song I had open in Doubletwist over the top of the song I was listening to in the HTC app. and the only way to stop it is to use task manager to kill Doubletwist.

Motorola Droid : Need Inline Remote Headphones

Nov 6, 2009

Loving my new Droid, but having a bit of a problem with the media playback. Once I get a track playing, and the screen is off, it is a major hassle when I want to simply pause for a second to talk to someone. I have to press button, swipe open, then press pause. The way I solved this on the iPod Touch was using the earbuds with the inline remote (even has a mic to use for calls in the iPhone). I am looking for a similar set up earbuds for the Droid, any suggestions?

2. Are there other apps that are better about inline images?

Android : Handle Messages Between The Main Thread(the Deafult UI Related Thread) And The User Created Gamethread

May 21, 2009

I am writing an application in which i need to handle messages between the main thread(the deafult UI related thread) and the user created Gamethread.

The requirement is like this.

An activity(say "Activity_X") is setting the view by "setContentView(some "View_Y")". In "Activity_X" i have implemeted "onCreateOptionsMenu()" and "onOptionsItemSelected()" fucntions for creating menus & a switch case for action to be taken on selecting those menus.Menu has items like "resume/pause/zoom/" .

All action to be take on selecting these menus are implemented in "View_Y" in a separate Gamethread by extending "Thread" class.

So whenever a menu is selected in "Activity_X" i need to send a message to "View_Y". And on receiving this ,a particular action/method should be called in View_Y(GameThread).

How can i achieve this using Handlers?Is there any other way of doing this? Please do share with me some code snippets for these.
