  • launching mapview from main activity (button)

    - by arc
    Hi all. Going round in circles here i think. I have an activity called Locate; public class Locate extends Activity { public static String lat; public static String lon; public static String number; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.locate); final Button buttonMaps = (Button) findViewById(R.id.ButtonMaps); buttonMaps.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); try { Intent i = new Intent(getBaseContext(), displayMap.class); i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); startActivity(i); } catch (ActivityNotFoundException e) { Toast.makeText(getBaseContext(), "Activity Not Found", Toast.LENGTH_SHORT).show(); } }}); // Toast.makeText(getBaseContext(), "lat: " + lat + " long: " + lon + " from: " + testname, Toast.LENGTH_LONG).show(); } If I make the displayMap class into a normal Activity, and just have display a toast message confirming it has loaded - then it works fine. If i do this though; public class displayMap extends MapActivity { /** Called when the activity is first created. */ public void onCreate() { setContentView(R.layout.displaymap); Toast.makeText(getBaseContext(), "Display Map", Toast.LENGTH_SHORT).show(); } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } } Then as soon as I click the Button, I get a force close. I have the correct 'uses-library' tag in my manifest; <application android:icon="@drawable/icon" android:label="@string/app_name"> <uses-library android:name="com.google.android.maps" /> I don't get what it just force closes everytime i try and load it. If I make this my onClick handler then it will fire up a working googlemaps/default mapview public void onClick(View v) { Toast.makeText(getBaseContext(), "Button Pressed", Toast.LENGTH_SHORT).show(); Uri uri=Uri.parse("geo:"+Locate.lat+","+Locate.lon); StartActivity(new Intent(Intent.ACTION_VIEW, uri)); } But that is not what I am trying to do, I want my own - so that I can add overlays etc to it. But it does prove that the permission are set correctly and that the lib is there. The logcat error when the app FCs is a Unexpected DEX error. Can anyone point in the right direction here?

  • Unexpected behavior of IntentService

    - by kknight
    I used IntentService in my code instead of Service because IntentService creates a thread for me in onHandleIntent(Intent intent), so I don't have to create a Thead myself in the code of my service. I expected that two intents to the same IntentSerivce will execute in parallel because a thread is generated in IntentService for each invent. But my code turned out that the two intents executed in sequential way. This is my IntentService code: public class UpdateService extends IntentService { public static final String TAG = "HelloTestIntentService"; public UpdateService() { super("News UpdateService"); } protected void onHandleIntent(Intent intent) { String userAction = intent .getStringExtra("userAction"); Log.v(TAG, "" + new Date() + ", In onHandleIntent for userAction = " + userAction + ", thread id = " + Thread.currentThread().getId()); if ("1".equals(userAction)) { try { Thread.sleep(20 * 1000); } catch (InterruptedException e) { Log.e(TAG, "error", e); } Log.v(TAG, "" + new Date() + ", This thread is waked up."); } } } And the code call the service is below: public class HelloTest extends Activity { //@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Intent selectIntent = new Intent(this, UpdateService.class); selectIntent.putExtra("userAction", "1"); this.startService(selectIntent); selectIntent = new Intent(this, UpdateService.class); selectIntent.putExtra("userAction", "2"); this.startService(selectIntent); } } I saw this log message in the log: V/HelloTestIntentService( 848): Wed May 05 14:59:37 PDT 2010, In onHandleIntent for userAction = 1, thread id = 8 D/dalvikvm( 609): GC freed 941 objects / 55672 bytes in 99ms V/HelloTestIntentService( 848): Wed May 05 15:00:00 PDT 2010, This thread is waked up. V/HelloTestIntentService( 848): Wed May 05 15:00:00 PDT 2010, In onHandleIntent for userAction = 2, thread id = 8 I/ActivityManager( 568): Stopping service: com.example.android/.UpdateService The log shows that the second intent waited the first intent to finish and they are in the same thread. It there anything I misunderstood of IntentService. To make two service intents execute in parallel, do I have to replace IntentService with service and start a thread myself in the service code? Thanks.

  • Using android gesture on top of menu buttons

    - by chriacua
    What I want is to have an options menu where the user can choose to navigate the menu between: 1) touching a button and then pressing down on the trackball to select it, and 2) drawing predefined gestures from Gestures Builder As it stands now, I have created my buttons with OnClickListener and the gestures with GestureOverlayView. Then I select starting a new Activity depending on whether the using pressed a button or executed a gesture. However, when I attempt to draw a gesture, it is not picked up. Only pressing the buttons is recognized. The following is my code: public class Menu extends Activity implements OnClickListener, OnGesturePerformedListener { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); //create TextToSpeech myTTS = new TextToSpeech(this, this); myTTS.setLanguage(Locale.US); //create Gestures mLibrary = GestureLibraries.fromRawResource(this, R.raw.gestures); if (!mLibrary.load()) { finish(); } // Set up click listeners for all the buttons. View playButton = findViewById(R.id.play_button); playButton.setOnClickListener(this); View instructionsButton = findViewById(R.id.instructions_button); instructionsButton.setOnClickListener(this); View modeButton = findViewById(R.id.mode_button); modeButton.setOnClickListener(this); View statsButton = findViewById(R.id.stats_button); statsButton.setOnClickListener(this); View exitButton = findViewById(R.id.exit_button); exitButton.setOnClickListener(this); GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); } public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { ArrayList<Prediction> predictions = mLibrary.recognize(gesture); // We want at least one prediction if (predictions.size() > 0) { Prediction prediction = predictions.get(0); // We want at least some confidence in the result if (prediction.score > 1.0) { // Show the gesture Toast.makeText(this, prediction.name, Toast.LENGTH_SHORT).show(); //User drew symbol for PLAY if (prediction.name.equals("Play")) { myTTS.shutdown(); //connect to game // User drew symbol for INSTRUCTIONS } else if (prediction.name.equals("Instructions")) { myTTS.shutdown(); startActivity(new Intent(this, Instructions.class)); // User drew symbol for MODE } else if (prediction.name.equals("Mode")){ myTTS.shutdown(); startActivity(new Intent(this, Mode.class)); // User drew symbol to QUIT } else { finish(); } } } } @Override public void onClick(View v) { switch (v.getId()){ case R.id.instructions_button: startActivity(new Intent(this, Instructions.class)); break; case R.id.mode_button: startActivity(new Intent(this, Mode.class)); break; case R.id.exit_button: finish(); break; } } Any suggestions would be greatly appreciated!

    - by tomgamer
    Newb alert, I'm sure I'm doing something dumb here. I've been progressively expanding my UI, and I want to add a ListView in the middle of my UI. When I add it and change the activity to extend a ListActivity instead of just an Activity, I'm getting a Force Close. Using 1.5. Does a ListView not work embedded in a RelativeLayout?

    Hey Everyone, I am trying to implement a ListView that is composed of rows that contain a View on the left followed by a TextView to the right of that.

  • iPhone App not saving values to .plist file

    - by Trent
    Hey everyone. I am working on an app that displays a modal the first time the consumer uses it. I have a .plist file that will store the information I request once the Save button is pressed. I can read from the .plist file fine and when I run my save method it SEEMS to work fine but the .plist file is not updating. I'm not so sure of the problem here. I show the modal like this. - (void) getConsumerInfo { NSString *filePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"consumer.plist"]; NSMutableDictionary *plistConsumerInfo = [[NSMutableDictionary alloc] initWithContentsOfFile:filePath]; NSString *hasAppeared = [plistConsumerInfo objectForKey:@"HasAppeared"]; if(hasAppeared != kHasAppeared) { ConsumerInfoViewController *tmpConsumerInfoVC = [[ConsumerInfoViewController alloc] initWithNibName:@"ConsumerInfoView" bundle:nil]; self.consumerInfoViewController = tmpConsumerInfoVC; [self presentModalViewController:consumerInfoViewController animated:YES]; [tmpConsumerInfoVC release]; } } This is called by the viewDidLoad method in the first view phone when the app is started. Within the consumerInfoViewController I have textfields that have data entered and when the Save button is pressed it calls this method. - (IBAction)saveConsumerInfo:(id)sender { NSString *filePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:@"consumer.plist"]; NSMutableDictionary *plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:filePath]; NSString *tmpDiversName = txtDiversName.text; NSString *tmpLicenseType = txtLicenseType.text; NSString *tmpLicenseNum = txtLicenseNumber.text; NSString *tmpHasAppeared = @"1"; NSString *tmpNumJumps = @"3"; [plistDict setValue:[[NSString alloc] initWithFormat:@"%@", tmpDiversName] forKey:@"ConsumerName"]; [plistDict setValue:[[NSString alloc] initWithFormat:@"%@", tmpLicenseType] forKey:@"LicenseType"]; [plistDict setValue:[[NSString alloc] initWithFormat:@"%@", tmpLicenseNum] forKey:@"LicenseNumb"]; [plistDict setValue:[[NSString alloc] initWithFormat:@"%@", tmpNumJumps] forKey:@"NumJumps"]; [plistDict setValue:[[NSString alloc] initWithFormat:@"%d", tmpHasAppeared] forKey:@"Show"]; [plistDict writeToFile:filePath atomically: YES]; NSLog([[NSString alloc] initWithContentsOfFile:filePath]); [self dismissModalViewControllerAnimated:YES]; } This all runs fine with no hiccups but the file is never updated. I would like it to update so I can use this information throughout the app and update the flag so it will not show the view again once the data is entered. Please let me know if there is anymore information you need. Thanks in advance!

  • Queue ExternalInterface calls to Flash Object in UpdatePanel - Needs Improvement?

    - by Laramie
    A Flash (actually Flex) object is created on an ASP.Net page within an Update Panel using a modified version of the embedCallAC_FL_RunContent.js script so it can be written in dynamically. It is re-created with this script with each partial postback to that panel. There are also other Update Panels on the page. With some postbacks (partial and full), External Interface calls such as $get('FlashObj').ExternalInterfaceFunc('arg1', 0, true); are prepared server-side and added to the page using ScriptManager.RegisterStartupScript. They're embedded in a function and stuffed into Sys.Application's load event, for example Sys.Application.add_load(funcContainingExternalInterfaceCalls). The problem is that because the Flash object's state state may change with each partial postback, the Flash (Flex) object and/or External Interface may not be ready or even exist yet in the DOM when the JavaScript - Flash External Interface call is made. It results in an "Object doesn't support this property or method" exception. I have a working strategy to make the ExternalInterface calls immediately if Flash is ready or else queue them until such time that Flash announces its readiness. //Called when the Flash object is initialized and can accept ExternalInterfaceCalls var flashReady = false; //Called by Flash when object is fully initialized function setFlashReady() { flashReady = true; //Make any queued ExternalInterface calls, then dequeue while (extIntQueue.length > 0) (extIntQueue.shift())(); } var extIntQueue = []; function callExternalInterface(flashObjName, funcName, args) { //reference to the wrapped ExternalInterface Call var wrapped = extWrap(flashObjName, funcName, args); //only procede with ExternalInterface call if the global flashReady variable has been set if (flashReady) { wrapped(); } else { //queue the function so when flashReady() is called next, the function is called and the aruments are passed. extIntQueue.push(wrapped); } } //bundle ExtInt call and hold variables in a closure function extWrap(flashObjName, funcName, args) { //put vars in closure return function() { var funcCall = '$get("' + flashObjName + '").' + funcName; eval(funcCall).apply(this, args); } } I set the flashReady var to dirty whenever I update the Update Panel that contains the Flash (Flex) object. ScriptManager.RegisterClientScriptBlock(parentContainer, parentContainer.GetType(), "flashReady", "flashReady = false;", true); I'm pleased that I got it to work, but it feels like a hack. I am still on the learning curve with respect to concepts like closures why "eval()" is apparently evil, so I'm wondering if I'm violating some best practice or if this code should be improved, if so how? Thanks.

Following documentation instructions, I have set up all the bundle thing: autoload.php: 'Ps' => __DIR__.'/../vendor/bundles', 'PHPPdf' => __DIR__.'/../vendor/PHPPdf/lib', 'Imagine' => array(__DIR__.'/../vendor/PHPPdf/lib', __DIR__.'/../vendor/PHPPdf/lib/vendor/Imagine/lib'), 'Zend' => __DIR__.'/../vendor/PHPPdf/lib/vendor/Zend/library', 'ZendPdf' => __DIR__.'/../vendor/PHPPdf/lib/vendor/ZendPdf/library', AppKernel.php: ... new Ps\PdfBundle\PsPdfBundle(), ... I guess all the setting up is correctly configured, as I am not getting any "library not found" nor anything on that way... So, after all that, I am doing this in the controller: ... use Ps\PdfBundle\Annotation\Pdf; ... /** * @Pdf() * @Route ("/pdf", name="_pdf") * @Template() */ public function generateInvoicePDFAction($name = 'Pedro') { return $this->render('AcmeStoreBundle:Shop:generateInvoice.pdf.twig', array( 'name' => $name, )); } And having this twig file: <pdf> <dynamic-page> Hello {{ name }}! </dynamic-page> </pdf> Well. Somehow, what I just get in my page is just the normal html generated as if it was a normal Response rendering. The Pdf() annotation is supposed to give the "special" behavior of creating the PDF file instead of rendering normal HTML. So, having the above code, when I request the route http://www.mysite.com/*...*/pdf, all what I get is the following HTML rendered: <pdf> <dynamic-page> Hello Pedro! </dynamic-page> </pdf> (so a blank HTML page with just the words Hello Pedro! on it. Any clue? Am I doing anything wrong? Is it mandatory to have the alternative *.html.twig apart from the *.pdf.twig version? I don't think so... :(

  • NSMutableArray can't be added to

    - by Dan Ray
    I've had this sort of problem before, and it didn't get a satisfactory answer. I have a viewcontroller with a property called "counties" that is an NSMutableArray. I'm going to drill down a navigation screen to a view that is about selecting the counties for a geographical search. So the search page drills down to the "select counties" page. I pass NSMutableArray *counties to the second controller as I push the second one on the navigation stack. I actually set that second controller's "selectedCounties" property (also an NSMutableArray) with a pointer to my first controller's "counties", as you'll see below. When I go to addObject to that, though, I get this: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: '*** -[NSCFArray insertObject:atIndex:]: mutating method sent to immutable object' Here's my code: in SearchViewController.h: @interface SearchViewController : UIViewController { .... NSMutableArray *counties; } .... @property (nonatomic, retain) NSMutableArray *counties; in SearchViewController.m: - (void)getLocationsView { [keywordField resignFirstResponder]; SearchLocationsViewController *locationsController = [[SearchLocationsViewController alloc] initWithNibName:@"SearchLocationsView" bundle:nil]; [self.navigationController pushViewController:locationsController animated:YES]; [locationsController setSelectedCounties:self.counties]; [locationsController release]; } in SearchLocationsViewController.h: @interface EventsSearchLocationsViewController : UIViewController <UITableViewDelegate, UITableViewDataSource> { ... NSMutableArray *selectedCounties; } ... @property (nonatomic, retain) NSMutableArray *selectedCounties; in SearchLocationsViewController.m (the point here is, we're toggling each element of a table being active or not in the list of selected counties): -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath]; if ([self.selectedCounties containsObject:[self.counties objectAtIndex:indexPath.row]]) { //we're deselcting! [self.selectedCounties removeObject:[self.counties objectAtIndex:indexPath.row]]; cell.accessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"red_check_inactive.png"]]; } else { [self.selectedCounties addObject:[self.counties objectAtIndex:indexPath.row]]; cell.accessoryView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"red_check_active.png"]]; } [tableView deselectRowAtIndexPath:indexPath animated:YES]; } We die at [self.selectedCounties addObject.... there. Now, when I NSLog myself [self.selectedCounties class], it tells me it's an NSCFArray. How does this happen? I understand about class bundles (or I THINK I do anyway), but this is explicitly a specific type, and it's losing it subclassing at some point in a way that kills the whole thing. I just completely don't understand why that would happen.

  • ProgressDialog does not display until after AsyncTask completes

    - by tedwards
    I am trying to display an indefinite ProgressDialog, while an AsyncTask binds to a RemoteService. The RemoteService builds a list of the users contacts when the service is first created. For a long list of contacts this may take 5~10 seconds. The problem I am having, is that the ProgressDialog does not display until after the RemoteService has built it's list of contacts. I even tried putting a Thread.sleep in to give the ProgressDialog time to show up. With the sleep statement the ProgressDialog loads and starts spinning, but then locks up as soon as the RemoteService starts doing it's work. If I just turn the AsyncTask into dummy code, and just let it sleep for a while, everything works fine. But when the task has to do actual work, it is like the UI just sits and waits. Any ideas on what Im doing wrong ? @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Log.d(IM,"Start Me UP!!"); setContentView(R.layout.main); Log.d(IM, "Building List View for Contacts"); restoreMe(); if (myContacts==null){ myContacts = new ArrayList<Contact>(); this.contactAdapter = new ContactAdapter(this, R.layout.contactlist, myContacts); setListAdapter(this.contactAdapter); new BindAsync().execute(); } else{ this.contactAdapter = new ContactAdapter(this, R.layout.contactlist, myContacts); setListAdapter(this.contactAdapter); } } private class BindAsync extends AsyncTask<Void, Void, RemoteServiceConnection>{ @Override protected void onPreExecute(){ super.onPreExecute(); Log.d(IM,"Showing Dialog"); showDialog(DIALOG_CONTACTS); } @Override protected RemoteServiceConnection doInBackground(Void... v) { Log.d(IM,"Binding to service in BindAsync"); try{ Thread.sleep(2000); } catch (InterruptedException e){ } RemoteServiceConnection myCon; myCon = new RemoteServiceConnection(); Intent i = new Intent(imandroid.this,MyRemoteService.class); bindService(i, myCon, Context.BIND_AUTO_CREATE); startService(i); Log.d(IM,"Bound to remote service"); return myCon; } @Override protected void onPostExecute(RemoteServiceConnection newConn){ super.onPostExecute(newConn); Log.d(IM,"Storing remote connection"); conn=newConn; } };

  • Various GPS Android Functionality Questions..

    - by Tyler
    Hello - I have a few questions (so far) with the the LocationManager on Android and GPS in general.. Feel free to answer any number of the questions below, and I appreciate your help in advance! (I noticed this stuff doesn't appear to be documented very well, so hopefully these questions will help others out too!) 1) I am using the following code, but I think there may be extra fluff in here that I do not need. Can you tell me if I can delete any of this? LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); LocationListener locationListener = new MyLocationListener(); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListener); LocationProvider locationProvider = lm.getProvider("gps"); Location currentLocation = lm.getLastKnownLocation(locationProvider.getName()); 2) Is there a way to hold off on the last step (accessing "getLastKnownLocation" until after I am sure I have a GPS lock? What happens if this is called and GPS is still looking for signal? 3) MOST importantly, I want to ensure I have a GPS lock before I proceed to my next method, so is there a way to check to see if GPS is locked on and getLastKnownLocation is up to date? 4) Is there a way to 'shut down' the GPS listener once it does receive a lock and getLastKnownLocation is updated? I don't see a need to keep this running for my application once I have obtained a lock.. 5) Can you please confirm my assumption that "getLastKnownLocation" is updated frequently as the receiver moves? 6) In my code, I also have a class called "MyLocationListener" (code below) that I honestly just took from another example.. Is this actually needed? I assume this updates my location manager whenever the location changes, but it sure doesn't appear that there is much to the class itself! private class MyLocationListener implements LocationListener { @Override public void onLocationChanged(Location loc) { if (loc != null) { //Toast.makeText(getBaseContext(), "Location changed : Lat: " + loc.getLatitude() + " Lng: " + loc.getLongitude(), Toast.LENGTH_SHORT).show(); } } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub } }

  • NfcAdapter.getDefaultAdapter(this) returns null in emulator

  • Android OnClick in ListView calling parent function

    - by user1321683
    I have an Android application with a ListView in it, the ListView will setup fine but now I want a image in the ListView to be clickable. I do this by using 2 classes, the Activity class (parent) and an ArrayAdapter to fill the list. In the ArrayAdapter I implement a OnClickListener for the image in the list that I want to be clickable. So far it all works. But now I want to run a function from the activity class when the onClick, for the image in the list, is run but I do not know how. Below are the 2 classes that I use. First the Activity class: public class parent_class extends Activity implements OnClickListener, OnItemClickListener { child_class_list myList; ListView myListView; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // setup the Homelist data myList = new child_class_list (this, Group_Names, Group_Dates); myListView = (ListView) findViewById(R.id.list); // set the HomeList myListView.setAdapter( myList ); myListView.setOnItemClickListener(this); } void function_to_run() { // I want to run this function from the LiscView Onclick } public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // do something } } And the ArrayAdapter from where I want to call a function from the Activity class: public class child_class_list extends ArrayAdapter<String> { // private private final Context context; private String[] mName; private String[] mDate; public child_class_list (Context context, String[] Name, String[] Date) { super(context, R.layout.l_home, GroupName); this.context = context; this.mName = Name; this.mDate = Date; } @Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); View rowView = inflater.inflate(R.layout.l_home, parent, false); ImageView selectable_image = (ImageView) rowView.findViewById(R.id.l_selectable_image); selectable_image.setOnClickListener(new OnClickListener() { public void onClick(View v) { // I want to run the function_to_run() function from the parant class here } } ); // get the textID's TextView tvName = (TextView) rowView.findViewById(R.id.l_name); TextView tvDate = (TextView) rowView.findViewById(R.id.l_date); // set the text tvName.setText (mName[position]); tvDate.setText (mDate[position]); return rowView; } } If anyone knows how to run the function in the activity class from the arrayadapter or how to set the image onClickListener in the Activity Class I would greatly apriciate the help.

  • Why is my Interface Builder wiring so bonkers and what can I do to straighten it out?

    - by editor
    I've been working on an iPhone application in XCode and Interface Builder of the Tab Bar project type. After getting a table view of topics (business sectors) working fine I realized that I would need to add a Navigation Control to allow the user to drill into a subtopics (subsectors) table. As a green Objective-C developer, that was confusing, but I managed to get it working by reading various documentation trying out a few different IB options. My current setup is a Tab Bar Controller with Tab 1 as a Navigation Controller and Tab 2 a plain view with a Table View placed into it. The wiring works: I can log when table rows are selected and I'm ready to push a new View Controller onto the stack so that I can display the subtopics Table View. My problem: For some reason the first tab's Table View is a delegate and dataSource of the second ta. It doesn't make sense to me and I can't figure out why that's the only setup that works. Here is the wiring: Navigation Controller (Sectors) is a delegate of Tab Bar Navigation Bar is a delegate of Navigation Controller (Sectors) View Contoller (Sectors) has a view of Table View Table View (in Navigation Controller (Sectors)) is a delegate of First View Controller (Companies) Table View (in Navigation Controller (Sectors)) is a dataSource outlet of First View Controller (Companies) First View Controller (Companies) First View Contoller (Sectors) has a view of Table View Table View (in First View Controller (Companies)) is not hooked up to a dataSource outlet and is not a delegate When I click the tab buttons and look at the Inspector I see that the first tab is correctly hooked up to my MainWindow.xib and the second tab has selected a nib called SecondView.xib. It's in the File's Owner of MainWindow.xib where I inherit UITableViewDataSource and UITableViewDelegate (and also UITabBarControllerDelegate) in the .h, and in the .m where I implement the delegate methods. Why does this setup only work when the Table View in my first tab (View Controller (Sectors)) is a delegate and dataSource of the second tab? I'm confused: why wouldn't it need to be hooked up to the Navigation Controller-enabled tab in which the Table View is seen (Navigation Controller (Sectors))? The Table View seen on the second tab has neither dataSource and is not a delegate. I'm having trouble getting a pushViewController to fire (self.navigationController is not nil but the new View Controller still doesn't load) and I suspect that I need to work out this IB wiring issue before I can troubleshoot why the Nav Controller won't push a new View Controller onto the stack. if(nil == self.navigationController) { NSLog(@"self.navigationController is nil."); } else { NSLog(@"self.navigationController is not nil."); SectorList *subsectorViewController = [[SectorList alloc] initWithNibName:@"SectorList" bundle:nil]; subsectorViewController.title = @"Subsectors"; [[self navigationController] pushViewController:subsectorViewController animated:YES]; [subsectorViewController release]; }

  • Adding GestureOverlayView to my SurfaceView class, how to add to view hierarchy?

    - by Codejoy
    I was informed in a later answer that I have to add the GestureOverlayView I create in code to my view hierarchy, and I am not 100% how to do that. Below is the original question for completeness. I want my game to be able to recognize gestures. I have this nice SurfaceView class that I do an onDraw to draw my sprites, and I have a thread thats running it to call the onDraw etc . This all works great. I am trying to add the GestureOverlayView to this and it just isn't working. Finally hacked to where it doesn't crash but this is what i have public class Panel extends SurfaceView implements SurfaceHolder.Callback, OnGesturePerformedListener { public Panel(Context context) { theContext=context; mLibrary = GestureLibraries.fromRawResource(context, R.raw.myspells); GestureOverlayView gestures = new GestureOverlayView(theContext); gestures.setOrientation(gestures.ORIENTATION_VERTICAL); gestures.setEventsInterceptionEnabled(true); gestures.setGestureStrokeType(gestures.GESTURE_STROKE_TYPE_MULTIPLE); gestures.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); //GestureOverlayView gestures = (GestureOverlayView) findViewById(R.id.gestures); gestures.addOnGesturePerformedListener(this); } ... ... onDraw... surfaceCreated(..); ... ... public void onGesturePerformed(GestureOverlayView overlay, Gesture gesture) { ArrayList<Prediction> predictions = mLibrary.recognize(gesture); // We want at least one prediction if (predictions.size() > 0) { Prediction prediction = predictions.get(0); // We want at least some confidence in the result if (prediction.score > 1.0) { // Show the spell Toast.makeText(theContext, prediction.name, Toast.LENGTH_SHORT).show(); } } } } The onGesturePerformed is never called. Their example has the GestureOverlay in the xml, I am not using that, my activity is simple: @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); Panel p = new Panel(this); setContentView(p); } So I am at a bit of a loss of the missing piece of information here, it doesn't call the onGesturePerformed and the nice pretty yellow "you are drawing a gesture" never shows up.

  • NSOperation inside NSOperationQueue not being executed

    - by Martin Garcia
    I really need help here. I'm desperate at this point. I have NSOperation that when added to the NSOperationQueue is not being triggered. I added some logging to see the NSOperation status and this is the result: Queue operations count = 1 Queue isSuspended = 0 Operation isCancelled? = 0 Operation isConcurrent? = 0 Operation isFinished? = 0 Operation isExecuted? = 0 Operation isReady? = 1 Operation dependencies? = 0 The code is very simple. Nothing special. LoadingConflictEvents_iPad *loadingEvents = [[LoadingConflictEvents_iPad alloc] initWithNibName:@"LoadingConflictEvents_iPad" bundle:[NSBundle mainBundle]]; loadingEvents.modalPresentationStyle = UIModalPresentationFormSheet; loadingEvents.conflictOpDelegate = self; [self presentModalViewController:loadingEvents animated:NO]; [loadingEvents release]; ConflictEventOperation *operation = [[ConflictEventOperation alloc] initWithParameters:wiLr.formNumber pWI_ID:wiLr.wi_id]; [queue addOperation:operation]; NSLog(@"Queue operations count = %d",[queue operationCount]); NSLog(@"Queue isSuspended = %d",[queue isSuspended]); NSLog(@"Operation isCancelled? = %d",[operation isCancelled]); NSLog(@"Operation isConcurrent? = %d",[operation isConcurrent]); NSLog(@"Operation isFinished? = %d",[operation isFinished]); NSLog(@"Operation isExecuted? = %d",[operation isExecuting]); NSLog(@"Operation isReady? = %d",[operation isReady]); NSLog(@"Operation dependencies? = %d",[[operation dependencies] count]); [operation release]; Now my operation do many things on the main method, but the problem is never being called. The main is never executed. The most weird thing (believe me, I'm not crazy .. yet). If I put a break point in any NSLog line or in the creation of the operation the main method will be called and everything will work perfectly. This have been working fine for a long time. I have been making some changes recently and apparently something screw things up. One of those changes was to upgrade the device to iOS 5.1 SDK (iPad). To add something, I have the iPhone (iOS 5.1) version of this application that use the same NSOperation object. The difference is in the UI only, and everything works fine. Any help will be really appreciated. Regards,

  • Broadcast receiver, check status, turning off connection with F8

    - by yoann
    I am using eclipse with android sdk 3.2 I have some problems to make my broadcast receiver working when the connection is lost. first I have checked the type of network to make sure I understand well : ConnectivityManager manager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE); boolean is3g = manager.getNetworkInfo( ConnectivityManager.TYPE_MOBILE) .isConnectedOrConnecting(); boolean isWifi = manager.getNetworkInfo( ConnectivityManager.TYPE_WIFI) .isConnectedOrConnecting(); NetworkInfo info = manager.getActiveNetworkInfo(); if (info != null) Toast.makeText(getApplicationContext(), info.getTypeName(), Toast.LENGTH_LONG).show(); else Toast.makeText(getApplicationContext(), "Pas de connexion", Toast.LENGTH_LONG).show(); if (!is3g) Log.i("Network Listener", "DISCONNECTED"); else Log.i("Network Listener", "CONNECTED"); == this is a mobile network, I'm connected Then I press F8 or I make : telnet localhost 5554 gsm data off to stop the connection Here is my dynamic broadcast receiver in an activity : public class ActivityA extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.query); this.registerReceiver(this.networkStateReceiver, new IntentFilter( ConnectivityManager.CONNECTIVITY_ACTION)); } BroadcastReceiver networkStateReceiver = new BroadcastReceiver() { @Override public void onReceive(Context context, Intent intent) { ConnectivityManager connMgr = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connMgr.getActiveNetworkInfo(); //i have tried several things : State networkState = networkInfo.getState(); // if (networkState.compareTo(State.DISCONNECTED) == 0) ... if (networkInfo != null && networkInfo.isConnected()) { Toast.makeText(getApplicationContext(), "CONNECTED", Toast.LENGTH_LONG).show(); Log.i("Network Listener", "Connected"); } else { Toast.makeText(getApplicationContext(), "DISCONNECTED", Toast.LENGTH_LONG).show(); Log.i("Network Listener", "Network Type Changed"); Intent offline = new Intent(AccountInfoActivity.this, OfflineWorkService.class); startService(offline); } }; My manifest : <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> The problem is : when the activityA is launched, my broadcast receive something and it displays "Connected"(Log) and my toast. When I turn off the connection manually, nothing happend. My service is not started, log message are not displayed, only toast messages work ... And even better, when I turn on the connection again (by pressing F8), I test again the type of connection, Toast messages are shown but this time Log messages don't work. Problems happend when I press F8. Anyway, I think I miss something with broadcast receivers, it's not totally clear. Please help me.
