    - by orangecl4now
    I have a xib. the xib has a button that swaps another xib. the second xib has a uitextfield and a uilabel. how do I make the keyboard go away when I'm done typing? what do I need to wire or code? the second xib has it's own class (called CustomSign.m) Inside CustomSign.m, I've implemented the following method -(void)textFieldDidEndEditing:(UITextField *)textField { [customText resignFirstResponder]; signedLabel.text = customText.text; } - (void)awakeFromNib { //assume textField is an ivar that is connected to the textfield in IB [customText setDelegate:self]; } I get the following warning Class "CustomSign" does not implement the UITextFieldDelegate protocol

  • How can I apply a theme/style to an Action android

    - by skooter
    In Android, how can I apply a style to an API action? I am using the RingtoneManager.RINGTON_PICKER action to let the user select an alarm, and would like to apply the standard theme that the other child-activities use. Does anyone know how I can apply a theme? The code I'm using to open the RINGTONE_PICKER is Intent intent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER); ((Activity)mContext).startActivityForResult(intent, BackendConstant.RINGTONE_CODE);

  • Re-load Android activity data

    - by rhinds
    Hi, I am writing an Android app, part of which will be a survey involving multiple pages of checkbox question and answers. I have created an activity to display the question and options (from the DB) and what I want to do now is when i press the "Next" button it should just reload the current activity with the next question set from the database. (the activity starts with survey.getNextQuestion() - so its just a case of refreshing the activity so it updates) Im sure this is a simple thing to do -any ideas? Thanks

  • Encrypt/ Secure communication Android app <-> REST webservice

    - by Ascorbin
    I want to create a backend for my android app with Tapestry5 and this http://code.google.com/p/t5-restful-webservices/ plugin. The app will communicate with the server by calling REST methods both for registered users (that would be easy to secure I guess) as well as unregistered users. Now of course I don't want people to just call that webservice from a browser. How can I make sure that only my app can make calls to this backend?

  • I can't get my Android program to run correctly on an AVM in Eclipse

    - by Wes
    This is a simple question about getting started with developing Android apps using Eclipse. I have followed all the tutorials on the developer site for installing Eclipse, the SDK and the ADT plugin. When trying to run a simple Hello World program, everything seems to compile correctly, but then the virtual machine comes up empty. In the Console Window it reads: The program then just sits and my text never comes up. Any idea with what the problem could be?

  • List View Selected Index Changed in a multi-selectable list view

    - by Anton Indrawan
    I have a windows form with a listview control. I set the MultiSelect property to true and I added a selected_index changed event. I get the event fired when I click the same index as the current selected index. My expectation is that I will not get the event fired. The strange thing is that the event fired 1 second after I click the index. I appreciate for any reply to explain why this is happening.

  • You are only allowed to have a single MapView in a MapActivity

    - by ProNeticas
    I have a function that shows a map page so I can get the user to choose their current location. But if you run this function twice it crashes the App with the Single MapView in a MapActivity error (i.e. opening that settings view again). public void showMapSetterPage(View v) { Log.i(DEBUG_TAG, "Settings screen, set map center launched"); // Set which view object we fired off from set_pv(v); // Show Map Settings Screen setContentView(R.layout.set_map_center); // Initiate the center point map if (mapView == null) { mapView = (MapView) findViewById(R.id.mapview); } mapView.setLongClickable(true); mapView.setStreetView(true); mapView.setBuiltInZoomControls(false); mapView.setSatellite(false); mapController = mapView.getController(); mapController.setZoom(18); LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); Location location = lm .getLastKnownLocation(LocationManager.GPS_PROVIDER); int lat = (int) (location.getLatitude() * 1E6); int lng = (int) (location.getLongitude() * 1E6); Log.i(DEBUG_TAG, "The LAT and LONG is: " + lat + " == " + lng); point = new GeoPoint(lat, lng); // mapController.setCenter(point); mapController.animateTo(point); } So I have a button that shows this View and onClick="showMapSetterPage". But if you go back to the settings screen out of the map and click the button again I get this error: 03-06 20:55:54.091: ERROR/AndroidRuntime(28014): Caused by: java.lang.IllegalStateException: You are only allowed to have a single MapView in a MapActivity How can I delete the MapView and recreate it?

  • Android TimePicker hour field disappears after orientation change

    - by sosiouxme
    I am using a TimePicker under API 1.5 and when the orientation is changed on my device (a stock G1 running 1.6 - though NOT on the 1.5/1.6 emulator), the hour field goes blank. It still remembers the hour, it just doesn't show it. Is there any workaround for this? The same problem was described by someone else here: http://groups.google.com/group/android-beginners/browse_thread/thread/b4288004021b876/de5899a2bb291ab5 Nothing helpful was forthcoming - can StackOverflow do better?

  • Unable to install USB drivers for android

    - by Dave
    I'm running Win XP 64bit and am connecting a Motocliq to my computer. The device is recognized by windows and shows up in the device manager (Motorola ADB Interface), however when I try to install drivers (manually, from the usb_driver revision 3 provided by Android) it fails giving the error "The hardware was not installed because the wizard cannot find the necessary software." Does anyone else have experience installing this drivers on XP64bit/Motocliq?

I'm looking for something reasonably priced, and I don't want a phone contract, data plan, etc. Anyone have any suggestions?

  • Is MobiForms for Android worth investigating ?

    - by Alan B
    I'm working my way through the NotePad tutorial, and that's all fine - I'm not a Java programmer but it's close enough to C# (or vice versa) to make it easy to pick up. I'm surprised that there aren't any RAD tools for Android apart from Mobiforms. Is there anyone out there with experience of Mobiforms ?

  • Add newlines to a text resource in Android?

    - by shmuelp
    I have a custom Dialog that contains only a TextView to display some text in my application. The documentation lists that only the b, i, u, tt, big, small, sup, sub, and strike tags are supported. I really need to add some newlines for readability. Do I need to change to a more complicated layout, or is there some way to encode newlines in the resource? I tried adding br tags, but that did not help.

I want to handle opening the file within my application. I have been looking at this C# File Browser. Unfortunately, I have not been able to figure out how to do meet my second need. (If anybody can clear that up for me, I would like that even better.) Thanks for any help.

  • ListView causing OutOfMemory Error

    - by Michael
    So I am not really given a reason to the right of this error message. I am not exactly sure why this is happening but my guess though is that it has to do with the fact that there are around ~50 good quality drawables. Upon scrolling really fast, the app crashes. I feel as if I am mitigating most common issues with ListView and crashing such as using View Holders as well as only initiating the inflater once. Process: com.example.michael.myandroidappactivity, PID: 20103 java.lang.OutOfMemoryError at android.graphics.BitmapFactory.nativeDecodeAsset(Native Method) Here is the code public class ImageAdapter extends BaseAdapter { private Context context; private ArrayList<Integer> imageIds; private static LayoutInflater inflater; public ImageAdapter(Context _context, ArrayList<Integer> _imageIds) { context = _context; imageIds = _imageIds; } @Override public int getCount() { return imageIds.size(); } @Override public Object getItem(int position) { return null; } @Override public long getItemId(int position) { return 0; } static class ViewHolder{ ImageView img; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder = null; View rowView = null; if(rowView==null) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); rowView = inflater.inflate(R.layout.listview_layout, parent, false); holder = new ViewHolder(); holder.img = (ImageView) rowView.findViewById(R.id.flag); rowView.setTag(holder); } else { holder = (ViewHolder) rowView.getTag(); } holder.img.setImageResource(imageIds.get(position)); return rowView; } }
