  • How to Implement Custom List View for the list Items in Android Application

    - by avadhani
    I had a problem with the list view having both parent list and the child list of the list activity(implemented through database query). I wish to show them differing their properties by changing the text style (parent list items are in bold, child list items are in normal style). The following is the code from which all the child and parent list items having the same style(bold): String sql = "SELECT Parentid,Childid,Name from (select com.Parentid, com.Childid, com.Name from table1 mem inner join table2 cd on mem.column1=cd.column1 inner join table3 com on com.childid = mem.childid where Parentid is NULL UNION SELECT com.Parentid, com.Childid,com.Name from table1 mem inner join table3 com on com.childid = mem.childid inner join table2 cd on mem.column1=cd.column1 where Parentid is NOT NULL) a group by Parentid, Childid;"; Cursor cdata = myDbHelper.getView(sql); and the List Adapter is: private static final String fields[] = {"Name"}; int[] names = new int[] {R.id.name}; SimpleCursorAdapter adapter2 = new SimpleCursorAdapter(this,R.layout.clientlist1, cdata, fields,names ); and the clientlist.xml is: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:id="@+id/MainLayout" android:padding="5px"> <TextView android:id="@+id/name" android:layout_alignParentRight="true" android:layout_width="fill_parent" android:layout_height="wrap_content" android:textSize="12sp" android:textColor="#104082" android:textStyle="bold" android:layout_weight="1" /> From this i am getting the list having the complete list having both parent and child list items in a single list view. I wish to differ in their text style(bold, normal) for parent and child items respectively. Please help me with the code/links. Thanks a lot in advance.

  • Eclipse hangs when rebuilding after the addition of an external JAR file.

    - by celestialorb
    I'm fairly new to Eclipse so if this is something simple I apologize, however when I attempt to add an external JAR file to my build path (specifically the "rt.jar" file which contains certain tools that I require) and then rebuild my project, Eclipse will hang at the end of the Build process. It'll get to 100% then just hang there using 100% of one of my CPU cores. At first I thought it may have been due to the relatively large size of the rt.jar file, but I tried using smaller JAR files and it still hung at 100%. Any help would be greatly appreciated! If there is something wrong with using the rt.jar file does anyone know of another JAR file that contains both tools for dealing with SOAP requests as well as XML/DOM manipulation? Thanks again!

  • Should I create protected constructor for my singleton classes?

    - by Vijay Shanker
    By design, in Singleton pattern the constructor should be marked private and provide a creational method retuning the private static member of the same type instance. I have created my singleton classes like this only. public class SingletonPattern {// singleton class private static SingletonPattern pattern = new SingletonPattern(); private SingletonPattern() { } public static SingletonPattern getInstance() { return pattern; } } Now, I have got to extend a singleton class to add new behaviors. But the private constructor is not letting be define the child class. I was thinking to change the default constructor to protected constructor for the singleton base class. What can be problems, if I define my constructors to be protected? Looking for expert views....

  • I can't use Spring filters in servlet-context XML

  • JavaApplicationStub with SWT causing problems

    - by mystro
    I created an application in Eclipse that uses SWT for the GUI. I've attempted to deploy the application using the Eclipse deploy, but it seems that when I do that, LSUIElement is not respected, and I can't force the application to disappear from the dock. Nonwhistanding that issue, the application actually deploys ok and is runnable. I attempted to deploy the application using Jar Bundler, but when I try to run the application, I get the following errors: 2010-06-09 21:44:02.564 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x10021f260 of class NSCFString autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.568 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x10010a0a0 of class NSCFNumber autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.569 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x1001127a0 of class NSCFString autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.582 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x7fff70b7af70 of class NSCFString autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.583 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x100123ea0 of class NSCFData autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.587 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x100225b90 of class NSCFDictionary autoreleased with no pool in place - just leaking 2010-06-09 21:44:02.588 JavaApplicationStub[89045:2003] * __NSAutoreleaseNoPool(): Object 0x100225ee0 of class __NSFastEnumerationEnumerator autoreleased with no pool in place - just leaking in a very, very, very, long list. The application launches and appears to hang with the icon constantly bouncing in the dock, and the first GUI menu only partially loaded (it looks like one of the text boxes is semi visible, and the overall rectangle is the right size, but the GUI is not showing properly. It is essentially hung.) I'm hoping someone has had experience with this problem, and may be able to help! Thanks!

  • How to use locks/synchronization here

    - by MasterGberry
    I have this code block here and i need to make sure the rankedPlayersWaitingForMatch is synchronized between threads properly. I was going to use synchronize but that i don't think will work here because of the variable being used in the if statement. I read online about final Lock lock = new ReentrantLock(); but I am a bit confused on how to use it in this case properly with the try/finally block. Can I get a quick example? Thanks // start synchronization if (rankedPlayersWaitingForMatch.get(rankedType).size() >= 2) { Player player1 = rankedPlayersWaitingForMatch.get(rankedType).remove(); Player player2 = rankedPlayersWaitingForMatch.get(rankedType).remove(); // end synchronization // ... I don't want this all to be synchronized, just after the first 2 remove() } else { // end synchronization // ... }

  • I need data structure for effective handling with dates

    - by ante.sabo
    What I need is something like Hashtable which I will fill with prices that were actual at desired days. For example: I will put two prices: January 1st: 100USD, March 5th: 89USD. If I search my hashtable for price: hashtable.get(February 14th) I need it to give me back actual price which was entered at Jan. 1st because this is the last actual price. Normal hashtable implementation won't give me back anything, since there is nothing put on that dat. I need to see if there is such implementation which can find quickly object based on range of dates.

  • How to add an element to an array without a modification of the old array or creation a new one?

    - by Roman
    I have the following construction: for (String playerName: players). I would like to make a loop over all players plus one more special player. But I do not want to modify the players array by adding a new element to it. So, what can I do? Can I replace players in the for (String playerName: players) by something containing all elements of the players plus one more element?

  • A Question on Encapsulation.

    - by Bragaadeesh
    Hi, I know that encapsulation is binding the members and its behavior in one single entity. And it has made me think that the members have to be private. Does this mean if a class having public members is not following 100% Encapsulation rule? Thanks

  • Using an empty keystore password used to be possible?

    - by TomTasche
    When signing an apk after a long break from Android development I was surprised that I'm no longer able to enter an empty keystore password to unlock it. Is it just me or has this been possible before? If so, when did that change and how can I manage to unlock the keystore anyway? Some background: maybe I'm just crazy and didn't use an empty password for the keystore before, but the one and only possible password that I could have been using instead doesn't work either (I swear, there's no chance I'd have used another password!).

  • Logs are filling up with httpclient.wire.content dumps. How can I turn it off?

    - by ?????
    My catalina logs are filling up with gobs of statements like: /logs/catalina.out:2010-05-05 02:57:19,611 [Thread-19] DEBUG httpclient.wire.content - >> "[0x4] [0xc][0xd9][0xf4][0xa2]MA[0xed][0xc2][0x93][0x1b][0x15][0xfe],[0xe]h[0xb0][0x1f][0xff][0xd6][0xfb] [0x8f]O[0xd4][0xc4]0[0xab][0x80][0xe8][0xe4][0xf2][\r]I&[0xaa][0xd2]BQ[0xdb](zq[0xcd]ac[0xa8] on and on forever. I searched every config file in both tomcat and apache for the statements that purportedly turn this on as described here: http://hc.apache.org/httpclient-3.x/logging.html And I don't see where this logging as been enabled. No other .war I deployed does this. The log4j configuration block in the app isn't doing it. Any ideas? I'm using an S3 library for grails that may be the source for these. However when I run this application on my development machine (in both develop and deploy configs), I'm not seeing it.

    I am using Netbeans 6.1 and Tomcat 6.0.1.6. I made some very minor changes to a project that had been working and now I am getting the following error: com.sun.rave.web.ui.appbase.ApplicationException: org.apache.jasper.JasperException: Could not add one or more tag libraries. The only change I made was to a backing bean method, no new UI components, jsp, etc. Any direction would be greatly appreciated. Thanks!

  • How to use regular expression and assign result into valuables in Android??

    - by user304078
    Dear all, I have to say sorry for my poor English first... I have a string named s_Result which will be parsed from Internet, the format may be "Distance: 2.8km (about 9 mins)", and there are 4 variables which are f_Distance, m_DistanceUnit, f_timeEst, m_timeEstUnit. My question is, how to parse s_Result and assign 2.8, km, 9, mins into f_Distance, m_distanceUnit, f_timeEst, and m_timeEstUnit respectively using regular expression?? I tried using "\d+(.\d+)?" in RegEx Tester and the result showed 2 matches found, but if use "\\d+(\\.\\d+)?" in Android code, it showed nothing matched!!! Is there any suggestion?? Thanks for your help!!

  • Lucene setboost doesn't work

    - by Keven
    Hi all, OUr team just upgrade lucene from 2.3 to 3.0 and we are confused about the setboost and getboost of document. What we want is just set a boost for each document when add them into index, then when search it the documents in the response should have different order according to the boost I set. But it seems the order is not changed at all, even the boost of each document in the search response is still 1.0. Could some one give me some hit? Following is our code: String[] a = new String[] { "schindler", "spielberg", "shawshank", "solace", "sorcerer", "stone", "soap", "salesman", "save" }; List strings = Arrays.asList(a); AutoCompleteIndex index = new Index(); IndexWriter writer = new IndexWriter(index.getDirectory(), AnalyzerFactory.createAnalyzer("en_US"), true, MaxFieldLength.LIMITED); float i = 1f; for (String string : strings) { Document doc = new Document(); Field f = new Field(AutoCompleteIndexFactory.QUERYTEXTFIELD, string, Field.Store.YES, Field.Index.NOT_ANALYZED); doc.setBoost(i); doc.add(f); writer.addDocument(doc); i += 2f; } writer.close(); IndexReader reader2 = IndexReader.open(index.getDirectory()); for (int j = 0; j < reader2.maxDoc(); j++) { if (reader2.isDeleted(j)) { continue; } Document doc = reader2.document(j); Field f = doc.getField(AutoCompleteIndexFactory.QUERYTEXTFIELD); System.out.println(f.stringValue() + ":" + f.getBoost() + ", docBoost:" + doc.getBoost()); doc.setBoost(j); }

  • Why is JavaMail Transport.send() a static method?

    - by skiphoppy
    I'm revising code I did not write that uses JavaMail, and having a little trouble understanding why the JavaMail API is designed the way it is. I have the feeling that if I understood, I could be doing a better job. We call: transport = session.getTransport("smtp"); transport.connect(hostName, port, user, password); So why is Eclipse warning me that this: transport.send(message, message.getAllRecipients()); is a call to a static method? Why am I getting a Transport object and providing settings that are specific to it if I can't use that object to send the message? How does the Transport class even know what server and other settings to use to send the message? It's working fine, which is hard to believe. What if I had instantiated Transport objects for two different servers; how would it know which one to use? In the course of writing this question, I've discovered that I should really be calling: transport.sendMessage(message, message.getAllRecipients()); So what is the purpose of the static Transport.send() method? Is this just poor design, or is there a reason it is this way?

  • 64 bits ant.jar

    - by sonic
    I have installed 64 bits RHEL. I have following questions regarding ant.jar for the system. I was not able to find ant.jar build with 64 bit JVM from the apache website. Do I have to build it form the source code, if I intend to run the jar on 64 bit JVM? Would it speed up the build process if I use ant.jar build with 64 bit JVM and run it on 64 bit JVM?

  • Inheriting the main method

    - by Eric
    I want to define a base class that defines a main method that instantiates the class, and runs a method. There are a couple of problems though. Here is the base class: public abstract class Strategy { abstract void execute(SoccerRobot robot); public static void main(String args) { Strategy s = new /*Not sure what to put here*/(); s.execute(new SoccerRobot()) } } And here is an example derived class: public class UselessStrategy { void execute(SoccerRobot robot) { System.out.println("I'm useless") } } It defines a simple execute method, which should be called in a main method upon usage as a the main application. However, in order to do so, I need to instantiate the derived class from within the base class's main method. Which doesn't seem to be possible. I'd rather not have to repeat the main method for every derived class, as it feels somewhat unnessary. Is there a right way of doing this?

  • Hibernate: Walk millions of rows and don't leak memory

    - by Autocracy
    The below code functions, but Hibernate never lets go of its grip of any object. Calling session.clear() causes exceptions regarding fetching a joined class, and calling session.evict(currentObject) before retrieving the next object also fails to free the memory. Eventually I exhaust my heap space. Checking my heap dumps, StatefulPersistenceContext is the garbage collector's root for all references pointing to my objects. public class CriteriaReportSource implements JRDataSource { private ScrollableResults sr; private Object currentObject; private Criteria c; private static final int scrollSize = 10; private int offset = 1; public CriteriaReportSource(Criteria c) { this.c = c; advanceScroll(); } private void advanceScroll() { // ((Session) Main.em.getDelegate()).clear(); this.sr = c.setFirstResult(offset) .setMaxResults(scrollSize) .scroll(ScrollMode.FORWARD_ONLY); offset += scrollSize; } public boolean next() { if (sr.next()) { currentObject = sr.get(0); if (sr.isLast()) { advanceScroll(); } return true; } return false; } public Object getFieldValue(JRField jrf) throws JRException { Object retVal = null; if(currentObject == null) { return null; } try { retVal = PropertyUtils.getProperty(currentObject, jrf.getName()); } catch (Exception ex) { Logger.getLogger(CriteriaReportSource.class.getName()).log(Level.SEVERE, null, ex); } return retVal; } }

  • 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?

  • Restore previously serialized JFrame-object, how?

    - by elementz
    Hi all. I have managed to serialize my very basic GUI-object containing a JTextArea and a few buttons to a file 'test.ser'. Now, I would like to completely restore the previously saved state from 'test.ser', but seem to have a misconception of how to properly deserialize an objects state. The class MyFrame creates the JFrame and serializes it. public class MyFrame extends JFrame implements ActionListener { // Fields JTextArea textArea; String title; static MyFrame gui = new MyFrame(); private static final long serialVersionUID = 1125762532137824262L; /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub gui.run(); } // parameterless default contructor public MyFrame() { } // constructor with title public MyFrame(String title) { } // creates Frame and its Layout public void run() { JFrame frame = new JFrame(title); JPanel panel_01 = new JPanel(); JPanel panel_02 = new JPanel(); JTextArea textArea = new JTextArea(20, 22); textArea.setLineWrap(true); JScrollPane scrollPane = new JScrollPane(textArea); scrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED); panel_01.add(scrollPane); // Buttons JButton saveButton = new JButton("Save"); saveButton.addActionListener(this); JButton loadButton = new JButton("Load"); loadButton.addActionListener(this); panel_02.add(loadButton); panel_02.add(saveButton); // Layout frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getContentPane().add(BorderLayout.CENTER, panel_01); frame.getContentPane().add(BorderLayout.SOUTH, panel_02); frame.setSize(300, 400); frame.setVisible(true); } /* * */ public void serialize() { try { ObjectOutputStream oos = new ObjectOutputStream(new FileOutputStream("test.ser")); oos.writeObject(gui); oos.close(); } catch (Exception e) { // TODO: handle exception e.printStackTrace(); } } public void actionPerformed(ActionEvent ev) { System.out.println("Action received!"); gui.serialize(); } } Here I try to do the deserialization: public class Deserialize { static Deserialize ds; static MyFrame frame; public static void main(String[] args) { try { ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.ser")); frame = (MyFrame) ois.readObject(); ois.close(); } catch (FileNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (ClassNotFoundException e) { // TODO Auto-generated catch block e.printStackTrace(); } } Maybe somebody could point me into the direction where my misconception is?

  • getRequestProperty("Authorization") always returns null

  • F5 irule with RESTful services

    - by Kyle Hayes
    I'm trying to come up with a rule on our F5 to direct traffic to our Tomcat server appropriately. We are deploying separate WAR files for each RESTful service. So, we would like to have the following URIs as an example: /services/quiz/01234/ /services/user/54321/ Where 'quiz' and 'user' are quiz.war and user.war respectively. We want to direct the traffic at the F5 level for /services/ to be the root and the rest of the URI to be directed to the Tomcat server. How do we accomplish this? Edit The browser url for a resource would look like http://www.domain.com/services/quiz/01234/ I want BIG-IP to send the request to tomcat as http://tomcatserver:8080/quiz/01234/ so basically remove /services and append everything after it to the tomcat domain. I would think this would be an easy regex, right?
