Introduce new member variables of your class:

this.setText(x: + mCurX + ,y: + mCurY );
mOffsetX = mCurX - 10; // 10 was the initial coordinate

offset values.
this.setLayoutParams (p);
}
I hope this helps as a pointer. Note that after you placed the object
to a new position, you have to remember the new coordinates (instead
of (10,10) where you started originally).
ACTION_DOWN is called when you click the mouse button, ACTION_MOVE is
called while you click and drag, and ACTION_UP is called when you
release the mouse button. Replace mouse by finger on the actual
device :-)
I hope this is what you meant.

what you have to do is, remember the coordinates that you get with the

Remember the distance (difference) between those coordinates and the
original coordinates of your image (call that offsetX and offsetY),
and subsequently in ACTION_MOVE always add those offset values.

[android-developers] Re: my rotated bitmaps unrotate immediately after invoking setCenter() method
Problem solved. Had nothing to do the 'setCenter()' fn. Problem was with the way I was computing my angle/orientation updates: when the map is recentered, the user's cartesian coords are also automatically shifted, so must use geodesic info instead. On Dec 21 2008, 8:46 pm, DMT droiddevelo...@gmail.com wrote: It seems that invoking the .setCenter(mygeopoint) method on a MapController object has the side effect of setting the orientation of any rotated bitmaps back to the original orientation. Has anyone else also experienced this? My problem is that I'm writing a map application that needs to rotate an arrow bitmap to point in the direction of the cellphone's motion, and I want to periodically automatically re-center the map so that the user's position does not drift off the map. However, each time I call 'setCenter(mygeopoint)', my arrow bitmap unrotates back to its original heading, therefore the user loses the directional information. Anyone found a workaround for this problem? Thanks in advance. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Text animation question
Hello,
It is not enough to use a single TextView for the effect you need. You
should rather use TextSwitcher class.
Take a look at SDK samples. There is
com.example.android.apis.view.TextSwitcher1 class there. It is good
demonstration of using TextSwitcher class.
Hope this helps.

[android-developers] Dev Phone: Copying restricted files form device to PC
I have Android Dev Phone 1 and I want to be able to programatically copy files form it do my PC (through USB). However, I cannot use adb pull because some of the files I want to copy are owned by different users that system. I can copy these files by starting shell on the device, then doing su, then copying the files to sdcard and then copying then from sdcard to my PC. Can I do this automatically, without doing su manually? Also, it seems Dev Phone doesn't know the cp command to copy files. I have to use cat from_file to_file. Surely there is a simpler solution...? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Connecting a Google Dev phone to UK Vodafone
Just in case anyone else is struggling with this, there is a solution,
and it's easy.
When you get your new Dev phone, and you stick a Vodafone SIM in it,
it fails to connect to Google's servers and can't initialise. It seems
to be bricked. But wait, all is not lost.
Buy a T-Mobile pay-as-you-go SIM for £5. Put it in your Dev phone and
get in your car. Drive to the within range of your nearest T-Mobile
tower ('not so much a network, more a sparse matrix'). Switch on your
phone, and register with Google.
Ah, you say, but I don't want a T-Mobile phone, they have virtually no
coverage outside city centres. Verily, I say unto you, be not afraid,
for I bring tidings of great joy. You may now switch off your Dev
phone, extract the T-Mobile SIM card, put in your Vodafone SIM card,
and switch back on. And Lo! all is well and it works.
I've only tried this fix with UK Vodafone, because that's the network
I wanted to use. But if you have trouble getting your Dev phone past
the 'cannot connect to Google servers' phase with your own wireless
provider of choice, this may work for you too.

[android-developers] my app sometimes take 1 second to load, sometimes 50 seconds
Hi all, I'm pretty stumped here. I've got an app that more or less follows the layout of LunarLander, with an Activity, a View, and a Thread. The View extends SurfaceView and the thread is what does the drawing. It is relatively light on resources - 16 PNGs totalling 240KB, one simple layout xml, and one simple values xml. The load time for the app is all over the map. It sometimes loads in under a second, sometimes it takes as much as 50 seconds. But as long as I don't touch it, it *always* finishes loading eventually (if I try to interact with it, I get the isn't responding window and have the option to kill it.. though even then it will finish loading if I wait long enough). The behavior is the same whether I'm running my code on the emulator or an actual ADP1. I've done a fair amount of logging to try to figure out what's going on, but I'm not getting anywhere. My activity's onStart() is always done in less than 2 seconds; my view and thread are also ready to go within 2 seconds.

[android-developers] Re: Text animation question
That worked great, and much more smoothly than an animation. Thanks!

Hello,
It is not enough to use a single TextView for the effect you need. You
should rather use TextSwitcher class.
Take a look at SDK samples. There is
com.example.android.apis.view.TextSwitcher1 class there. It is good
demonstration of using TextSwitcher class.
Hope this helps.

Hello,
I'm working on sometextanimationwith 2 left and right buttons,

The problem I'm finding, is that I want to keep the currenttextuntil
theanimationhas been completed, and _then_ change thetext(next

scroll.
Here's my XML foranimation(R.anim.anim_left):

And the code for the button:
if (v == btnLeft) {
TextView animWindow = (TextView)findViewById(R.id.txtScroll);Animationanim
= AnimationUtils.loadAnimation(Main.this,
R.anim.anim_down);
animWindow.startAnimation(anim);
final ArrayAdapterString namesArray = new ArrayAdapterString
(Main.this, R.array.myArray, getResources().getStringArray
(R.array.myArray));
setListAdapter(Names);

txtNames.setText(namesArray.getItem(Names));
}
Has anyone else experienced something similar to this, or have any
ideas?

[android-developers] Re: my app sometimes take 1 second to load, sometimes 50 seconds
Very strange. Someone pointed out to me that I really shouldn't be using com.android as a package, since it's not my domain. I just hadn't changed it from when I was mirroring LunarLander. And since I changed it, my apps has yet to take longer than 3 seconds to load. On Jan 10, 12:20 pm, bwilliam...@gmail.com bwilliam...@gmail.com wrote: Hi all, I'm pretty stumped here. I've got an app that more or less follows the layout of LunarLander, with an Activity, a View, and a Thread. The View extends SurfaceView and the thread is what does the drawing. It is relatively light on resources - 16 PNGs totalling 240KB, one simple layout xml, and one simple values xml. The load time for the app is all over the map. It sometimes loads in under a second, sometimes it takes as much as 50 seconds. But as long as I don't touch it, it *always* finishes loading eventually (if I try to interact with it, I get the isn't responding window and have the option to kill it.. though even then it will finish loading if I wait long enough). The behavior is the same whether I'm running my code on the emulator or an actual ADP1. I've done a fair amount of logging to try to figure out what's going on, but I'm not getting anywhere. My activity's onStart() is always done in less than 2 seconds; my view and thread are also ready to go within 2 seconds.

[android-developers] Re: JSON easy Marshall/Unmarshall
Thanks for the hint Mark - we'll try that as well.
Btw we just wanted to let everyone know that we've tried latest trunk code
from
http://fisheye.codehaus.org/browse/jackson/ (just pick the binary tarball
links in the bottom lefthand corner, install and, go to directory, and do
'ant dist' - then pickup jar from dist directory - we used lgpl version.
Then use the code we submitted below. But you will need to patch a few
classes in the jackson json code becuase they are referencing classes that
don't exist in android - for e.g. XMLGregorianCalendar . Whenever you get a
no classdef found error using this framework, go to that line in code,
comment it out, do ant clean/ant dist again, remove the library from
classpath in eclipse, add it again so that eclipse android plugin will
package it again inside your android project - rinse, repeast. You will need
to do this in two classes I think, and at 3-4 different places - you won't
have to comment out a LOT of code - if this works without any issues, we can
try talking to the author so that we can have compatibility with android. So
far, we can serialise/deserialise very complex objects to JSON successfully)

[android-developers] WebView: Need help with local file Urls in the browser
Hi, let's say I write content onto the local filesystem using Context.openFileOutput(). For the sake of this example one file IS index.html and one IS image.png. The former references the latter in the html code. How can I get the browser to display the content? I tried many different ways and failed so far. I can't just use the url: file:///data/data/com.myapp/files/index.html . The browser just says Web page not available. Also when loading the content of the index.html file directly, it does not show the image. Like this: contentWebView.loadDataWithBaseURL(file:///data/data/com.myapp/files/index.html , htmlHello, World!img src=\image.png\//html, text/html, utf-8, null); I wrote the content with Context.MODE_WORLD_READABLE. Any ideas? I read somewhere that I should provide a WebClient and override shouldOverrideUrlLoading for whatever reason. But that doesn't work at all for me. This method is never called (android-sdk- mac_x86-1.0_r2). I guess I can try to ask the user to turn off shared access for the sdcard and use that, but that's really not what I want. In a pinch though ... any ideas? Also when using Context.openFileInput/Output I can't use folders, right? Any ideas if the file system slows down when I have a thousand small files there?

And the button and checkbox are centered fine, but the are pinned to the left edge of teh layout and I want then pinned to the right edge instead. Does anyone know how i can accomplish this? Related, when specifying a button, is there a way to just have the button dynamically size to whatever text is holds?

[android-developers] Re: Touch *extremely* expensive performance-wise
Dianne, I want to thank you again for your advice - it actually helped. I process at most 10 touch movement events per second (good enough for the app) and sleep the UI thread after the moves - this did boost the second thread enough so that most of the app's time is spent in physics updates and drawing.

I'll try increasing that to see if it will make a difference. I'd rather run the game @ 40 fps by losing ~15 fps because of yielding than losing ~30 fps because of touch event throttling. If I am reading that right, that's not a yield, that is just adding more CPU using work on the main thread. :) What you want to do is force the main thread to actually stop running for a bit after processing an event, so that it isn't using the CPU and your other thread can run and the window manager doesn't immediately turn around and give you another event with more work to do. Now you got me confused :) but let me 1st explain that by yielding I meant that the game thread yielded to the UI one. My confusion (now) is that I thought (after your post) that the main UI thread was not given enough time to process touch events and the OS was doing something (more work) because of that and was leaving my app with less time to work. You're now saying it's the opposite, but that can't be the problem because before I added the yields, the game thread was running at full speed and the UI was so unresponsive (e.g. clicking the Menu button resulted in ANR) that I had to do something about it and start yielding to the UI thread from the game one occasionally. However, I realize that you're not really saying to not let the UI thread work but to make it unresponsive for a bit every now and then (after an event is processed) so that the game thread works more and less context switches (made by Android's thread scheduling mechanism, not by me marshalling calls) occur. Is that what you're saying? Now just before I was about to post this, I profiled the game and let me share some *very* interesting facts about the touch handling. I ran the game, touched (which triggers the profile start process), and immediately removed my finger from the screen and let the profiling finish. What I saw in Traceview is that 64.7% of the game's time went in drawing (which is great!), 33.8% in the game's update, and android.os.Handler.dispatchMessage(Message) takes the funny 0.2% - I'm mentioning dispatchMessage here because you'll see a DRASTIC change in a second. I then ran the game, touched the screen and started moving my finger without releasing it until the profiling stopped. What I saw in Traceview is that 49.1% went in the game's update code, only 9% in the draw code and now for the winner - Handler.dispatchMessage took 24.7% of the time :O :O :O This only makes me think that my assumption that the layers below the app are doing something more than expected :( I'm yet to find out why would the update vs draw time is 49% to 9% (maybe locking the canvas and event handling on the UI thread are somewhat related???), but having an overhead of 25% just because I'm touching the screen is too much for me. Cheers I'd rather control the priority myself :) How are you going to control the priority yourself? Now that you understand what I meant by yielding (that is, not to the OS but from the game to the main/UI thread) I guess that question is moot.

[android-developers] Re: Change linear layout programmatically - problem
Might it be because as stated in the docs for setLayoutParams() These
supply parameters to the parent of this view specifying how it should be
arranged. and in this case there's no parent of the view, so the attempted
operation is not valid.
You might want to try the same with some child view and probably will
work...

Hi!
I'm trying to change height layout from wrap_content to

public class BBB extends Activity

LinearLayout layout = (LinearLayout)findViewById(R.id.mainZZZ);
LayoutParams params = new LayoutParams

Why the activity can't be loaded after run-time changes?

[android-developers] Database Leak in LogCat - SQLiteDatabase, Cursor, Lifecycle
In LogCat I keep getting Database Leak found. The 'tag' is Database and the 'message' is Leak found. And its followed by many lines of red in LogCat. I'm using an SQLiteDatabase and I access it from two Activities and one Service. In the Service I explicitly close both the cursor and then the database since I can't use startManagingCursor in there. In both Activities I open the database in both onCreate and onResume and close in onPause. In one Activity I also use a cursor with startManagingCursor to manage that for me. So what is going on here? My app seems to be working almost all the time but the Database Leak found is very disconcerting.

[android-developers] Re: Need help working with xml layout
Yes, it's frustrating to say the least. Hard to understand why it makes certain UI decisions. BTW - in your code example you put wrap_contents. The actual property value is wrap_content. Not sure if that was just typed in the email or if you have that error in your code. OK - So I got my initial layout problems fixed by using relative layouts, but I'm still having problems with getting the TextView to wrap properly. Here is the new layout... ?xml version=1.0 encoding=utf-8? LinearLayout xmlns:android=http://schemas.android.com/apk/res/ android android:layout_width=fill_parent android:layout_height=fill_parent android:orientation=horizontal ImageView android:id=@+id/offerImage android:layout_width=75sp android:layout_height=75sp android:layout_margin=5sp / RelativeLayout xmlns:android=http://schemas.android.com/apk/res/ android android:layout_width=wrap_content android:layout_height=fill_parent LinearLayout xmlns:android=http://schemas.android.com/apk/res/ android android:layout_width=wrap_content android:layout_height=fill_parent android:layout_centerVertical=true android:orientation=vertical android:background=@drawable/red TextView android:id=@+id/productName android:layout_width=120sp android:layout_height=wrap_content android:textSize=16sp android:textColor=@color/screen_black android:background=@drawable/blue/ TextView android:id=@+id/salesPitch android:layout_width=wrap_content android:layout_height=wrap_content android:layout_marginTop=5sp android:layout_marginBottom=5sp android:textColor=#80ff android:text=Coming June 2009!/ /LinearLayout /RelativeLayout RelativeLayout xmlns:android=http://schemas.android.com/apk/res/ android android:layout_width=wrap_content android:layout_height=fill_parent android:background=@drawable/ green CheckBox android:id=@+id/favorite style=?android:attr/starStyle android:layout_width=wrap_content android:layout_height=wrap_content android:layout_marginLeft=5sp android:layout_marginRight=5sp android:layout_centerVertical=true android:layout_alignParentRight=true / Button android:id=@+id/buy android:layout_height=wrap_content android:layout_width=70sp android:autoText=true android:layout_toLeftOf=@id/favorite android:layout_centerVertical=true android:background=@drawable/ yellow android:padding=0sp / /RelativeLayout /LinearLayout Right now I have to set a fixed with for the TextView. If I set it to wrap_content, then long text will blast through the relative layout on the right, so the button and checkbox are not even shown on the screen. I've played with having the right-side layout set to fill_parent, but that ends up taking way more space than it needs and the TextView won't even display. Here's what I need... Button and CheckBox on right side get as much space as needed, Image on left takes space it needs, Layout in the middle uses the remaining space and wraps text as needed. Doesn't seem like that should be so hard.

[android-developers] Proper Intent for an image/jpeg picture when using addIntentOptions?
My app deals with tons of pictures that are on an arbitrary location of the device (typically somewhere on /sdcard, presumed private to the app). The gallery has a context menu that calls addIntentOptions on them so you can send them via MMS, use them as contact pictures, etc. How do I need to set the intent up for that? I set the type to image/ jpeg, because that seems to be the one everybody is looking for. I put the Bitmap into an extra stream named data, that seemed to satisfy the Crop Picture intent, but no-one else. I used Uri.fromFile() onto the File of the image itself, that seemed to work with the View Picture intent, but not the others. I tried MediaStore.Images.Media.getContentUri(), but that didn't do it. I tried using my own content provider that always returned a _data column on every query with a pointer to the file, but that didn't work either, presumably because it didn't like me setting the MIME type to image/jpeg. What's the proper way here? (And, while I'm on the soap box, I hate the decision to not use addIntentOptions on any of the core apps. Several times, I have wanted to use an image in the web browser as a contact icon.) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Common code with Eclipse
I've been able to get external JARs for common code (which uses the android.jar) to work. I'm using a pretty clumsy way and I'm sure there's a more elegant solution out there, but it works for me. Since it's been a while since I set it up, I might not remember the exact steps. Basically, I created a new Java project (I forgot which option precisely I used), but it's not an Android-specific project - it does not have the Android builders. In the project's settings, I added android.jar as an external JAR in the Java Build Path. With that, I'm able to write code that uses the Android SDK which is compiled and error-checked as I type. Now here is the clumsy part. When I want to use it in my actual project, I choose File (or right- click) - Export - Java/JAR File. Now pick a good place for the .jar file in your repository and export it. Good news is that Eclipse remembers your settings, so every time you export, you basically just need to click on Next and Finish. In your actual Android app, go to the project properties, Java Build Path, Libraries, and add your .jar file as an external JAR. Now here is the part that sucks: Every time you change your library, you'll need to re-export it, then click on the jar in the package explorer, right-click it and choose Refresh. Other than that, this works like a charm for me. Again, I'm sure people who are more familiar with Eclipse are scoffing and have a much better solution.

[android-developers] Re: Change linear layout programmatically - problem
There's this suspicious line:
java.lang.ClassCastException: android.view.ViewGroup$LayoutParams
Have you tried to explicitly write:
LinearLayout.LayoutParams
instead of just
LayoutParams
whereever it appears?
(because each Layout has their own set of LayoutParams that are not
necessarily compatible with each other).

There's this suspicious line:

Have you tried to explicitly write:
LinearLayout.LayoutParams
instead of just
LayoutParams
whereever it appears?
(because each Layout has their own set of LayoutParams that are not
necessarily compatible with each other).

[android-developers] Re: Touch *extremely* expensive performance-wise
Thanks, glad to hear it helped. Sorry I was slow responding to your last detailed message. Fwiw, you should generally avoid trying to directly control scheduling. Let the kernel schedule the threads as needed; the only issue you had here was that your main thread was using as much CPU as it could get, since it was continually processing touch events, so the kernel would schedule 50/50 between that and the game thread. Simply reducing the work being done by the main thread (by our little hacky sleep solution) is probably the best way to fix things. On Sat, Jan 10, 2009 at 1:19 PM, Stoyan Damov stoyan.da...@gmail.comwrote: Dianne, I want to thank you again for your advice - it actually helped. I process at most 10 touch movement events per second (good enough for the app) and sleep the UI thread after the moves - this did boost the second thread enough so that most of the app's time is spent in physics updates and drawing.

I'll try increasing that to see if it will make a difference. I'd rather run the game @ 40 fps by losing ~15 fps because of yielding than losing ~30 fps because of touch event throttling. If I am reading that right, that's not a yield, that is just adding more CPU using work on the main thread. :) What you want to do is force the main thread to actually stop running for a bit after processing an event, so that it isn't using the CPU and your other thread can run and the window manager doesn't immediately turn around and give you another event with more work to do. Now you got me confused :) but let me 1st explain that by yielding I meant that the game thread yielded to the UI one. My confusion (now) is that I thought (after your post) that the main UI thread was not given enough time to process touch events and the OS was doing something (more work) because of that and was leaving my app with less time to work. You're now saying it's the opposite, but that can't be the problem because before I added the yields, the game thread was running at full speed and the UI was so unresponsive (e.g. clicking the Menu button resulted in ANR) that I had to do something about it and start yielding to the UI thread from the game one occasionally. However, I realize that you're not really saying to not let the UI thread work but to make it unresponsive for a bit every now and then (after an event is processed) so that the game thread works more and less context switches (made by Android's thread scheduling mechanism, not by me marshalling calls) occur. Is that what you're saying? Now just before I was about to post this, I profiled the game and let me share some *very* interesting facts about the touch handling. I ran the game, touched (which triggers the profile start process), and immediately removed my finger from the screen and let the profiling finish. What I saw in Traceview is that 64.7% of the game's time went in drawing (which is great!), 33.8% in the game's update, and android.os.Handler.dispatchMessage(Message) takes the funny 0.2% - I'm mentioning dispatchMessage here because you'll see a DRASTIC change in a second. I then ran the game, touched the screen and started moving my finger without releasing it until the profiling stopped. What I saw in Traceview is that 49.1% went in the game's update code, only 9% in the draw code and now for the winner - Handler.dispatchMessage took 24.7% of the time :O :O :O This only makes me think that my assumption that the layers below the app are doing something more than expected :( I'm yet to find out why would the update vs draw time is 49% to 9% (maybe locking the canvas and event handling on the UI thread are somewhat related???), but having an overhead of 25% just because I'm touching the screen is too much for me. Cheers I'd rather control the priority myself :) How are you going to control the priority yourself? Now that you understand what I meant by yielding (that is, not to the OS but from the game to the main/UI thread) I guess that question is moot.

[android-developers] Re: DRAG AND DROP
Fwiw, changing layout parameters is a really inefficient way to do animations on the screen.

[android-developers] Re: WebView: Need help with local file Urls in the browser
no..my html files n my apk are referenced as href=file:///android_asset/filename.html image use the same base url On Jan 10, 2:05 pm, Mariano Kamp mariano.k...@gmail.com wrote: Hi, let's say I write content onto the local filesystem using Context.openFileOutput(). For the sake of this example one file IS index.html and one IS image.png. The former references the latter in the html code. How can I get the browser to display the content? I tried many different ways and failed so far. I can't just use the url: file:///data/data/com.myapp/files/index.html . The browser just says Web page not available. Also when loading the content of the index.html file directly, it does not show the image. Like this: contentWebView.loadDataWithBaseURL(file:///data/data/com.myapp/files/index.html , htmlHello, World!img src=\image.png\//html, text/html, utf-8, null); I wrote the content with Context.MODE_WORLD_READABLE. Any ideas? I read somewhere that I should provide a WebClient and override shouldOverrideUrlLoading for whatever reason. But that doesn't work at all for me. This method is never called (android-sdk- mac_x86-1.0_r2). I guess I can try to ask the user to turn off shared access for the sdcard and use that, but that's really not what I want. In a pinch though ... any ideas? Also when using Context.openFileInput/Output I can't use folders, right? Any ideas if the file system slows down when I have a thousand small files there?

[android-developers] Re: Common code with Eclipse
Thanks for the explanation. This sounds useful for creating reusable, user-created libraries. I guess my problem is that I was experimenting with importing external jars which were not android specific. These fail to load (which I guess should be obvious), with errors described previously. Jim On Jan 10, 5:34 pm, EboMike ebom...@gmail.com wrote: I've been able to get external JARs for common code (which uses the android.jar) to work. I'm using a pretty clumsy way and I'm sure there's a more elegant solution out there, but it works for me. Since it's been a while since I set it up, I might not remember the exact steps. Basically, I created a new Java project (I forgot which option precisely I used), but it's not an Android-specific project - it does not have the Android builders. In the project's settings, I added android.jar as an external JAR in the Java Build Path. With that, I'm able to write code that uses the Android SDK which is compiled and error-checked as I type. Now here is the clumsy part. When I want to use it in my actual project, I choose File (or right- click) - Export - Java/JAR File. Now pick a good place for the .jar file in your repository and export it. Good news is that Eclipse remembers your settings, so every time you export, you basically just need to click on Next and Finish. In your actual Android app, go to the project properties, Java Build Path, Libraries, and add your .jar file as an external JAR. Now here is the part that sucks: Every time you change your library, you'll need to re-export it, then click on the jar in the package explorer, right-click it and choose Refresh. Other than that, this works like a charm for me. Again, I'm sure people who are more familiar with Eclipse are scoffing and have a much better solution.

I had an issue with making anEclipselibrary and importing that into a project (Runtime validation errors, which I solved by importing each JAR file for HTTP MIME separately), and I seem to be having an equally lame issue right now. Adding the previous project's source to my build path gives this error: [2008-11-19 12:24:58 - Dex Loader] Unable to execute dex: null [2008-11-19 12:24:58 - MyApp] Conversion to Dalvik format failed: Unable to execute dex: null So a few questions come to mind: 1) What is this error referring to? Is this a problem with my Manifest (which is in a different library), or a limitation on how theEclipseplug-in works with the DVM?
