  • Adding a row to a ListView that displays "Loading" while information is downloaded. Like in the Market.

    - by user577139
    I've tried, but have had no luck trying to find this answer elsewhere. I want to add a row to the bottom of my listview that displays "Loading..." and maybe a spinning progress indicator. My program already loads additional information into the listview once the user scrolls to the bottom. But I want the user to be able to see that the program is indeed loading something. Example: If you go to the android marketplace and scroll to the bottom of one of the lists, the last row will say "Loading...". Then once the data is loaded, that bar is replaced with the first item of the new data. Sorry, it's a little hard to describe. I am NOT trying to add a footer to the bottom of the list view. I want it to be an actual item in the listview.

  • How to update a record with multiple keys

    - by OceanBlue
    I am trying a database app on Android. I want to use the SQLiteDatabase update(...) convenience method to update a record. Normally, for a WHERE clause of a single key this is working. Following code is working fine:- values.put("testname", "Quiz1"); mDB.update("Tests", values, "id=?", new String[]{"2"}); //this statement works However, I want to update a column in a table which has a combination of two keys as the unique identifier. I tried the following. This executes without exception, but nothing is updated. values.put("score", 60); mDB.update("Results", values, "studentid=? AND testid=?", new String[] { "2,1" }); // this statement does not work How to do it?

  • Sending images using Http Post

    - by primal
    I want to send an image from the android client to the Django server using Http Post. The image is chosen from the gallery. At present, I am using list value name Pairs to send the necessary data to the server and receiving responses from Django in JSON. Can the same approach be used for images (with urls for images embedded in JSON responses)? Also which of, accesssing images remotely without downloading them from the server or downloading and storing them in a Bitmap array and using them locally is a better method? The images are few in number (<10) and small in size (50*50 dip). Any tutorial to tackle these problems would be much appreciated.

  • Extending DataGrid/Changing DataGrids header

    - by drasto
    Is there any way how to override DataGrids header line ? Or at least its behaviour ? I'm trying to implement Outlook-like grouping of the table. That is allow user to drag column header out of the table to the dedicated area to sort by that column (for example XamDataGrid has that feature, you can see how it works here). I cannot use any commercial solutions. I will be thankfull for any experiences, ideas, code, notes or tutorials.

  • Calculating the angle between two points

    - by kingrichard2005
    I'm currently developing a simple 2D game for Android. I have a stationary object that's situated in the center of the screen and I'm trying to get that object to rotate and point to the area on the screen that the user touches. I have the constant coordinates that represent the center of the screen and I can get the coordinates of the point that the user taps on. I'm using the formula outlined in this forum: How to get angle between two points? -It says as follows "If you want the the angle between the line defined by these two points and the horizontal axis: double angle = atan2(y2 - y1, x2 - x1) * 180 / PI;". -I implemented this, but I think the fact the I'm working in screen coordinates is causing a miscalculation, since the Y-coordinate is reversed. I'm not sure if this is the right way to go about it, any other thoughts or suggestions are appreciated.

  • Panel in Windows Forms Application not clearing

    - by SwiftStriker00
    I'm working on my project: [Beer Pong Management System][1], a Windows Forms application. I am currently trying to add a whole tournament mode to it. In a nutshell, I've created a TabControl, with the first tab page with the settings and setup and the second page the brackets. There is a feature for each of the match-ups, that once there is a winner is decided, a yellow cancel button will appear in order to revert the tournament. However my issue is when i click the button the next match-up does not get removed in the series is going. See below: Image Here(not high enough rep to insert image) I have tried to set the MatchUp to null, I've tried dispose(), close(). even Parent.Controls.Remove(). Even after I switch tabs which is supposed to clear all, they still sit there when i come back. I have a feeling I might be loosing a reference or something because I can't even push new teams into them, they just sit there with their buttons. Does anyone have any tips or know of any known issues that might be causing this? Thanks. [1] _http://www.cs.rit.edu/~rmb1201/pages/code.shtml

  • Transparent Dialog Alignment

    - by feragusper
    I'm trying to get a custom dialog with a transparent background doing this way: this.getWindow().setBackgroundDrawableResource(R.drawable.transparent); (where "R.drawable.transparent" is a reference to the color "#00000000") The weird issue on this is that I can't align my dialog window. It's always aligned to the left, even if I implicit set the Gravity of the window using: this.getWindow().setGravity(Gravity.CENTER); And if I just comment the line which set the transparent background, the alignment works fine. Any help would be much appreciated! Thanks.

  • App crashes on back button / Activities & Intents

    - by paradroid666
    I have an android application which starts a new activity Intent startAuthorization = new Intent(AndroidActivity, AuthorizeUser.class); startActivityForResult(startAuthorization,4711); When that new activity is done (a ok button is clicked) I call setResult(RESULT_OK, returnResult); finish(); Which works fine. In case the user doesn't click the okay button but uses the return button of the phone (this arrow pointing around to the left) the application has a force close. I have set a breakpoint on the first line of my method onActivityResult but the debugger never stops there. I have no idea where the issue comes up - how can I find out? Is there a method I have to overwrite to handle this back button?

  • Getting back from security & location to my application

    - by sandman42
    Hi, I have an application that allows the user to enable GPS. In order to do it, first in the main activity I do: lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); if (!lm.isProviderEnabled(LocationManager.GPS_PROVIDER)){ showGpsOptions(); } showGpsOptions() is: private void showGpsOptions() { Intent gpsOptionsIntent = new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS); startActivityForResult(gpsOptionsIntent, BACK_FROM_GPS_ACT); } and finally I override main activity onActivityResult in this way: protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (requestCode == BACK_FROM_GPS_ACT){ ; } super.onActivityResult(requestCode, resultCode, data); } Problem: the page show up and works, but when I press back I get back to home screen.

  • Using 'ref code' related to the spinner option chosen

    - by user1508541
    I am trying to add a spinner function in a trial app which compares the frequency charts of earphones. I am trying to extract the info from " http://www.headphone.com/learning-center/build-a-graph.php " website. what I want to do is make the spinner work like the drop down list in the mentioned website. On further inspection what I found was that every dropdown element is provided with a unique code that is called when the particular element is selected. I need help in replicating the same in an android spinner.

  • Forwarding activity result to parent, with singleTop launch mode

    - by Joe
    I have two activities: a MainListActivity, and a DetailViewActivity. DetailViewActivity is set with android:launchMode="singleTop". When clicking an item in the "main list" activity, it launches the "detail view" activity via: startActivityForResult(detailIntent, REQUEST_CODE_DETAIL); If I then call setResult(RESULT_OK, resultData); and finish(); from within the Detail activity, that resultData is received by the "main list" activity's onActivityResult(..) method correctly. However, if I implement a "see previous"/"see next" type of navigation within the Detail activity, and implement it using singleTop, that result no longer gets sent back to the initial activity: Intent nextItemIntent = this.createIntent(nextId); nextItemIntent.setFlags(Intent.FLAG_ACTIVITY_FORWARD_RESULT); startActivity(nextItemIntent); // at this point, my DetailActivity's onNewIntent() method is called, and the new data is loaded properly But from here, when I call setResult(..) and finish(), my MainList activity never receives the new/updated result. Anyone know what I'm doing wrong?

  • Determining where to animate the map given a list of GeoPoints

    - by Itsik
    My android application loads some markers on an overlay onto a MapView. The markers are placed based on a dynamic list of GeoPoints. I want to move the map center and zoom into the area with most items. Naively, I can calculate the superposition of all the points, but I would like to remove the points that are very far from the mass of points from the calculation. Is there a known way to calculate this ? (e.g. probability, statistics .. ?)

  • Access Assests from another application?

    - by pcm2a
    I get a lot of requests in my application to allow for custom icons packs from BetterCut / Open Home. The way it seems to work is you install BetterCut or Open Home, then you can install tons of these free icon packs from the market. Once installed both those apps (and other apps) will poll for those icon packs and use the icons. I want to know how to poll the install applications for the asset folders that are available. I have opened up a few of the icon packs and verified that there is an assets folder in there and they are full of all the icon png files. I've searched on here, other code sites, google, etc but havn't found any leads.

  • Questions Regarding Handling of Received SMS

    - by Edwin
    Hi, i have managed to successfully write a little test app that can receive and send SMS, but got a couple of questions. (That's 'cos part of the code i copied from elsewhere and i would like to understand better). In my AndroidManifest as well as the sub-class of BroadcastReceiver, there is reference to the string literal "android.provider.Telephony.SMS_RECEIVED". However, i couldn't find any reference in the API that mentions this. Could someone point me to some reference that lists/explains these? As part of getting the message from the Intent, i did this: Object[] pdus = (Object[]) intent.getExtras().get("pdus"); Again this question is related to the use of hardcoded string literal. Where is the string "pdus" listed and described? Thanks in advance!

  • Convert bit vector (array of booleans) to an integer, and integer to bit vector, in Java.

    - by dreeves
    What's the best way to unstub the following functions? // Convert a bit-vector to an integer. int bitvec2int(boolean[] b) { [CODE HERE] } // Convert an integer x to an n-element bit-vector. boolean[] int2bitvec(int x, int n) { [CODE HERE] } Or is there a better way to do that sort of thing than passing boolean arrays around? This comes up in an Android app where we need an array of 20 booleans to persist and the easiest way to do that is to write an integer or string to the key-value store. I'll post the way we (Bee and I) wrote the above as an answer. Thanks!

  • Keystore and Aliases - is there a use to multiple aliases?

    - by Steve H
    When exporting a signed Android application using Eclipse, is there a purpose to using multiple aliases? According to the official guide about signing, it's recommended that you sign all applications with the same certificate to allow your applications to share data, code and be updated in modular fashion. Assuming that "alias", "key" and "certificate" are essentially interchangeable in this context, is there a reason why someone would want to use different aliases for all their applications? The only reason I can think of is that it adds more security to your applications, in the sense that a compromised key/password doesn't compromise everything. Are there other reasons? Also, is the generated key dependent on the name of the alias? In other words, if you change the name of the alias but not the password, would the generated certificate be different? Thanks.

  • Java Thread Message Passing

    - by pkulak
    I'm writing an Android app. I have a main method, which creates and runs a new Thread using an anonymous inner Runnable class. The run() method, when it's done, calls a method on it's parent class (in the main thread) that calls notifyDataSetChanged() so that the main thread can redraw the new data. This is causing all kinds of trouble (ViewRoot$CalledFromWrongThreadException). The thing is, this method being called from the worker thread is on the class that's created in the UI thread. Shouldn't that be running on the UI thread? Or am I missing something? Here's some code about what I'm talking about: public class Mealfire extends Activity { @Override public void onCreate(Bundle icicle) { (new Thread() { public void run() { // Do a bunch of slow network stuff. update(); } }).start(); } private void update() { myAdapter.notifyDatasetChanged(); } }

  • AsyncTask won't stop even when the activity has destroyed

    - by Raja
    Hi all, I have an AsyncTask object which starts executing when the activity is created and does stuff in the background (downloads upto 100 images). Everything works fine but there is this peculiar behavior which i'm not able to understand. For eg: when the android screen's orientation changes then the activity is destroyed and created again. So I override the onRetainNonConfigurationInstance() method and save all the downloaded data executed in the AsyncTask. My purpose of doing this is to not have AsyncTask run each time activity is destroyed-created during orientation changes, but as i can see in my logs the previous AsynTask is still executing. (The data is saved correctly though) I even tried to cancel the AsynTask in the onDestroy() method of the activity but the logs still show AsynTask as running. This is really strange behavior and would really be thankful if someone can tell me the correct procedure to stop/cancel the AsynTask. Thanks

    I have been reading about app engine but I still dont know what I can and cant do with it in a android application. Basically what I want to do is be able to create/manage a database in the cloud that the app can pull down and update the local database if needed.

I have never written any sort of Web Service calls or anything either but I have used them to get data and such Can this be done? Any tutorials out there to help me out?
