  • Child Activity in Android

    - by Martin Marinov
    So I have two Activities. The main is called Main, and the child one is called Child. When a button is clicked in the main activity it triggers the following piece of code: Intent i = new Intent(Main.this, Child.class); Main.this.startActivity(i); That opens the Child activity. As soon as I call finish() or press the back button within the child activity instead of going back to the main one, the app just closes. Can you give me a hint where the problem might be :( P.S. By trial and error I found out that if edit AndroidManifest.xml and add android:theme="@android:style/Theme.Dialog" within the declaration of Child the back button and calling finish() behaves as expected: closes the child activity and brings the main into focus. The problem is that when I start typing in an EditText the screen starts flickering (rather bizzare). So I can't use it as a dialog. My main activity uses the camera, so that might be making problems. Although when the child activity is started, the onPause event is fired and it stops the camera until onResume is called.

  • Two pass JSP page rendering

    - by dotsid
    Suppose an example. I have following interface: public interface DataSource<T> { Future<T> fetch(); } This datasource can do asynchronous data fetching. And we have following tag for using datasource in JSP: <html> <d:fetch from="${orderDS}" var="orders"> <c:foreach in="${orders}" var="order"> <div class="order"> <c:out value="${order.title}" /> </div> </c:foreach> </d:fetch> </html> So, what I want? I want JSP rendering engine to call my custom tag (FetchTag in this example) twice. On first call FetchTag will do DataSource.fetch() call and save Future locally as a object field. On second call FetchTag do Future.get() call and will be blocked until data becomes available. Is there any way to do such a thing?

  • Hosting images from unsecured servers (travelnow.com)

    - by i.am.not.aids
    Hi, My application needs to serve images hosted in travelnow.com (ie. this image) but the application only allow images hosted on a secured server (ie. https). What are my options? TravelNow's suggestion is as follows. How do I do this? Akamai image servers are not secure. Therefore you are unable to serve any of the image urls with a secure HTTPS URL. If you need to serve an image with HTTPS, you must temporarily save the image to your own secure server. This is suggested only for images to be saved as you use them or need them temporarily on the secure page. The hotel images file available from the Affiliate Center provides up to 1.5 million URLs at any time for all properties storing images in the Akamai system. It is not recommended or advised to store all files in advance on your own system since properties change and update images frequently. Although we are not responsible for the images each property stores on the Akamai system, YOU will be responsible for any customer issues arising from displaying outdated or saved image files on your own pages. Thanks! Adrian

  • Jakarta Regexp 1.5 Backreferences?

    - by Matt Smith
    Why does this match: String str = "099.9 102.2" + (char) 0x0D; RE re = new RE("^([0-9]{3}.[0-9]) ([0-9]{3}.[0-9])\r$"); System.out.println(re.match(str)); But this does not: String str = "099.9 102.2" + (char) 0x0D; RE re = new RE("^([0-9]{3}.[0-9]) \1\r$"); System.out.println(re.match(str)); The back references don't seem to be working... What am I missing?

  • SimpleDateFormat

    - by manu
    Hi, The following code is giving me the parsed date as "Wed Jan 13 00:00:00 EST 2010" instead of "Wed Jun 13 00:00:00 EST 2010". Any ideas much appreciated. SimpleDateFormat sf = new SimpleDateFormat("yyyy-mm-dd'T'HH:mm:ss"); String str = "2010-06-13T00:00:00"; Date date = sf.parse(str); System.out.println(" Date " + date.toString());

  • for loop will not loop

    - by Bjørn Jostein Aurheim
    I have a for loop that I will use to compute time intervals to add to an ArrayList. The problem is that I can not prove that the for loop is being executed. Nothing is printed when using the system.out.println() statement, and nothing is added to the array from inside the loop ... any sugestions? // lager tidspunkter og legger disse inn i en Array kalt tider tid.setTimer(16); tid.setMinutter(0); tid.setSekunder(0); tider.add(tid.asString());// String "16:00" is added as it should System.out.println("tiden er: "+tid.asString());// gives 16:00 printed for(int i=0;i>12;i++){ System.out.println("er i løkken");// gives nothing printed tid.increaseMinutter(30); System.out.println(tid.asString());// gives nothing printed tider.add(tid.asString()); }

  • How can I get the name of all tables in a JavaDB database?

    - by Jonas
    How can i programmatically get the names of all tables in a JavaDB database? Is there any specific SQL-statement over JDBC I can use for this or any built in function in JDBC? I will use it for exporting the tables to XML, and would like to do it this way so I don't miss any tables from the database when exporting.

  • Is this the right way to write a ProtocolDecoder in MINA?

    - by phpscriptcoder
    public class CustomProtocolDecoder extends CumulativeProtocolDecoder{ byte currentCmd = -1; int currentSize = -1; boolean isFirst = false; @Override protected boolean doDecode(IoSession is, ByteBuffer bb, ProtocolDecoderOutput pdo) throws Exception { if(currentCmd == -1) { currentCmd = bb.get(); currentSize = Packet.getSize(currentCmd); isFirst = true; } while(bb.remaining() > 0) { if(!isFirst) { currentCmd = bb.get(); currentSize = Packet.getSize(currentCmd); } else isFirst = false; //System.err.println(currentCmd + " " + bb.remaining() + " " + currentSize); if(bb.remaining() >= currentSize - 1) { Packet p = PacketDecoder.decodePacket(bb, currentCmd); pdo.write(p); } else { bb.flip(); return false; } } if(bb.remaining() == 0) return true; else return false; } } Anyone see anything wrong with this code? When a lot of packets are received at once, even when only one client is connected, one of them might get cut off at the end (12 bytes instead of 15 bytes, for example) which is obviously bad.

  • Pointers, links, object and reference count

    - by EugeneP
    String a = "a"; // allocate memory and write address of a memory block to a variable String b = "b"; // in a and b hold addresses b = a; // copy a address into b. // Now what? b value is completely lost and will be garbage collected //* next step a = null; // now a does not hold a valid address to any data, // still data of a object exist somewhere, yet we cannot get access to it. Correct me if there's a mistake somewhere in my reflexions. My question is: suppose anInstance object of type Instance has a property ' surname ' anInstance.getSurname() returns "MySurname". now String s = anInstance.getSurname(); anInstance = null; question is - is it true that getSurname value, namely MySurname will not be garbage collected because and only because it has active reference counter 0, and if other properties of anInstance have a zero reference counter, they'll be garbage collected?

  • Find common nodes from two linked lists using recursion

    - by Dan
    I have to write a method that returns a linked list with all the nodes that are common to two linked lists using recursion, without loops. For example, first list is 2 - 5 - 7 - 10 second list is 2 - 4 - 8 - 10 the list that would be returned is 2 - 10 I am getting nowhere with this.. What I have been think of was to check each value of the first list with each value of the second list recursively but the second list would then be cut by one node everytime and I cannot compare the next value in the first list with the the second list. I hope this makes sense... Can anyone help?

  • Not compile code blocks when publishing?

    - by Menno Gouw
    I have many lines i just use for debugging and helpers. Is there a way i can mark these so they do not compile when publishing a project but still can use when running/debugging my program within Eclipse? Even better would be to mark a certain field as debug only and discard everything that has to do with that field completely when publishing. I understand this might get one in trouble when using fields like that and using that in critical parts of the code. But i often find myself initializing a lot of debug fields then comment them out which results in errors down the line if i do not comment those out as well. So is there some way to handle this in a better and more efficient way?

  • Android how to create notification that resumes activity

    - by Adam Praiswater
    I a have a notification in a receiver that fires off fine, but it restarts the activity (thus clearing the edittexts and resetting the toggle button) How can i set it so that when its tapped on it resumes the activity rather that clearing and resetting everything? My current code doesnt work. Current Code String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date()); Intent intenti= new Intent(context, Locator.class); intenti.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intenti, 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context) .setSmallIcon(R.drawable.xxxxxxnotifyicon) .setContentTitle("xxxxxxx Link") .setContentText("Auto Check In Complete at " + currentDateTimeString); mBuilder.setContentIntent(contentIntent); mBuilder.setDefaults(Notification.DEFAULT_SOUND); mBuilder.setAutoCancel(true); NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(1, mBuilder.build());

  • No GPS Update retrieved? Problem in Code?

    - by poeschlorn
    Hello mates, I've got a serious problem with my GPS on my Nexus One: I wrote a kind of hello world with GPS, but the Toast that should be displayed isn't :( I don't know what I'm doing wrong...maybe you could help me getting this work. Here's my code: package gps.test; import android.app.Activity; import android.content.Context; import android.location.Location; import android.location.LocationListener; import android.location.LocationManager; import android.os.Bundle; import android.widget.Toast; public class GPS extends Activity { private LocationManager lm; private LocationListener locationListener; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); // ---use the LocationManager class to obtain GPS locations--- lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE); locationListener = new MyLocationListener(); lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 100, 1, locationListener); } 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 } } } Theoretically there should be a new toast every 100 milliseconds, shouldn't it? Or at least, when I change my position by one meter!? I've no idea why it doesn't. I must admit I'm new to the topic, maybe I've missed something? It would be great if you could give me a hint :) nice greetings, poeschlorn

  • Grails query not using GORM

    - by Tihom
    What is the best way to query for something without using GORM in grails? I have query that doesn't seem to fit in the GORM model, the query has a subquery and a computed field. I posted on stackoverflow already with no response so I decided to take a different approach. I want to query for something not using GORM within a grails application. Is there an easy way to get the connection and go through the result set?

  • Return type value if RunTimeException has been thrown and not catched.

    - by Alfred
    I am using Gson to parse Json. What I don't understand what the return type will be if you don't catch the Runtime Exception. I was expecting it to be null, but it is not null when evaluating with a simple if statement. My code looks something like this: public X x() { return gson.fromJson(jsonString, X.class); } then from another function I call the function: public void y() { final X x = x(); if (x == null) { System.out.println("x == null") } } I was expecting x to be null, but it isn't because the print statement is not called? What is the value of x? How can if them. I have my problem by using a catch block in the x() function and returning null. But I am just wondering what the value of function x() is(if any?)? Hopefully I make any sense at all.
