  • android keylistener losing key taps

    - by miannelle
    I am using a keylistener to get key taps. The problem is that once you tap the delete key, the next key tap is not registering. The key tap after that keeps working. If I tap 2 deletes in a row, they work, just no other keys. They just disappear. I put in a log test before the "if (keycode" section and it shows nothing after the first delete is pressed, unless it is another delete. I am using the following code (Thanks Shawn).: itemPrice.setKeyListener(new CalculatorKeyListener()); itemPrice.setRawInputType(Configuration.KEYBOARD_12KEY); class CalculatorKeyListener extends NumberKeyListener { public int getInputType() { return InputType.TYPE_CLASS_NUMBER; } @Override public boolean onKeyDown(View view, Editable content, int keyCode, KeyEvent event) { if (keyCode >= KeyEvent.KEYCODE_0 && keyCode <= KeyEvent.KEYCODE_9) { digitPressed(keyCode - KeyEvent.KEYCODE_0); } else if (keyCode == KeyEvent.KEYCODE_DEL) { deletePressed(); } return true; } @Override protected char[] getAcceptedChars() { return new char[] { 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 }; } } With this problem the keylistener provides no value to me. There must be something that I am missing. Thanks,

  • Android: writing a file to sdcard

    - by Sumit M Asok
    I'm trying to write a file from an Http post reply to a file on the sdcard. Everything works fine until the byte array of data is retrieved. I've tried setting WRITE_EXTERNAL_STORAGE permission in the manifest and tried many different combinations of tutorials I found on the net. All I could find was using the openFileOutput("",MODE_WORLD_READABLE) method, of the activity but how my app writes file is by using a thread. Specifically, a thread is invoked from another thread when a file has to be written, so giving an activity object didn't work even though I tried it. The app has come a long way and I cannot change how the app is currently written. Please, someone help me? CODE: File file = new File(bgdmanip.savLocation); FileOutputStream filecon = null; filecon = new FileOutputStream(file); // bgdmanip.savLocation holds the whole files path byte[] myByte; myByte = Base64Coder.decode(seReply); Log.d("myBytes", String.valueOf(myByte)); bos.write(myByte); filecon.write(myByte); myvals = x * 11024; seReply is a string reply from HttpPost response. the second set of code is looped with reference to x. the file is created but remains 0 bytes

  • Call webservice from Android using KSoap simply returning "error" string

    - by w00tfest99
    I'm trying to use ksoap to call a simple webservice. I followed this video to try to get started. When I call "getResponse()" on the envelope I just get the string "Error". There's no exceptions thrown or any other detail. I've successfully connected to a simple webservice I just setup on my local machine. Could this potentially be related to being behind a proxy server here at work? My code is below: String SOAP_ACTION="http://tempuri.org/CelsiusToFahrenheit"; String METHOD_NAME = "CelsiusToFahrenheit"; String NAMESPACE = "http://tempuri.org"; String URL = "http://w3schools.com/webservices/tempconvert.asmx"; SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME); PropertyInfo pi = new PropertyInfo(); pi.setName("Celsius"); pi.setValue("32"); request.addProperty(pi); SoapSerializationEnvelope envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11); envelope.dotNet = true; envelope.setOutputSoapObject(request); HttpTransportSE aht = new HttpTransportSE(URL); try { aht.call(SOAP_ACTION, envelope); SoapPrimitive results = (SoapPrimitive)envelope.getResponse(); } catch (Exception e) { e.printStackTrace(); }

  • Android: getTag/setTag and IllegalArgumentException

    - by Sparafusile
    Yes, I know you need a unique resource id when calling the version of these functions that requires a key, but I cannot for the life of me figure out how to create a resource id that can be used in this way. A final variable in my class wont work and neither will a hard coded value. Both threw an IllegalArgumentException. So what gives, how do you use these methods? Spara

  • Wrong item checked when filtering ListView in android

    - by aspartame
    I have a ListView with multiple choice entries where some are checked from the beginning using setItemChecked(position, true); I combine this with the filtering option setTextFilterEnabled(true) so it's easy to find a specific entry in the list. The problem is that when I filter the list the entries switch position in the list view. Take for example three entries: 'A', 'B' and 'C' where 'C' is checked beforehand (i.e. the entry at position 3 in the list). When I type a 'C' on the keyboard, only the 'C' entry is displayed (as intended). Now 'C' is not checked anymore, since the entry has moved from the checked position 3 to the unchecked position 1 in the list. This behavior leads to some not very welcome effects in the app. Is there a way to "move the selection with the filtering", i.e. bind the checked state to the entry and not to its initial position in the list? Or do I need to find a new approach? Thanks, Linus

    hi, When writing : CountDownTimer timer = new CountDownTimer(1000, 100) { @Override public void onTick(long l) { } @Override public void onFinish() { }; }.start(); are we actually starting a new thread that handles ticks ? or what is really happening behind ?

  • Android multiple spinners

    - by DixieFlatline
    Hello! I have 3 spinners (dropdown menus). I would like the user to select item from the first one and that would determine the options(different string array) on the second and on the third spinner. E.g. user selects the country in the first spinner and then gets popular music groups in that country on the second spinner and popular dishes on the third. What is the easiest way to do this?

  • Android app copy protection and data files

    - by Ben Mc
    I'm going to rephrase this question. As it turns out the original answer wasn't definitive and problems were found. ======================================================================= In my app, I access my sqlite database at the following hard-coded location in my code: /data/data/com.mydomain.appname/databases/database.db If I turn ON copy protection in the Market Place, will my app still have access to this location? Or will I have to change it to something like: */data-private/*data/com.mydomain.appname/databases/database.db (or something like this) Since I have a Dev phone only, I have no way of testing to see if my app still functions normally after turning on copy protection. Thank you!

  • Android: How to detect end of scroll

    - by Mix
    Hi! I need to implement HorizontalScrollView which is scrolled to predefined positions (similar to Home behaviour). It works with slow gestures, but does not work with flings. I hooked to View.onScrollChanged() and it is called when scrolling happened, but I can't determine when scrolling ends. In theory there should be a way to say that fling is over. Is there such API?

The problem is that the chars draws in Evi draw space(last char "i")!! It is possible to see if you zoom the picture, what am I doing wrong and how to fix this? screen shot can be found here:

  • Android Programmatically created Button Persistance

    - by WtLgi
    So in an app I'm messing around with I programmatically create some buttons. Then I setContentView(); to a different page. Then if I come back to the original page (on which I placed the programmatically created buttons), they no longer exist. I guess this makes sense as I am calling setContentView(R.layout.main); again which is just the original xml file with no data pointing to the buttons. So is there a way to have the buttons persist over such screen transitions? Thanks.

  • Android VideoView - Detect point of time in video

    - by Chris
    Hi all, I am using a VideoView to display a video. I am using setOnPreparedListener and setOnCompletionListener to do stuff before and after the video starts and ends. I was wondering how I could go about detecting some point of time in the video. For eg, say I want to write log to a file when the video has played for 10s. How can I detect the 10s mark? Thanks Chris
