  • Android - Making an activity display different things depending on what is clicked

    - by user3682017
    I have a listview that is populated by an arraylist of classes. public void populateThingsList(){ listExample.add(new Example("Example name", 1, "Example detail 1", "Example detail 2", R.drawable.1_icon, "Example detail 3")); listExample.add(new Example("Example name1", 2, "Example detail 1", "Example detail 2", R.drawable.2_icon, "Example detail 3")); listExample.add(new Example("Example name2", 3, "Example detail 1", "Example detail 2", R.drawable.3_icon, "Example detail 3")); listExample.add(new Example("Example name3", 4, "Example detail 1", "Example detail 2", R.drawable.4_icon, "Example detail 3")); listExample.add(new Example("Example name4", 5, "Example detail 1", "Example detail 2", R.drawable.5_icon, "Example detail 3")); listExample.add(new Example("Example name5", 6, "Example detail 1", "Example detail 2", R.drawable.6_icon, "Example detail 3")); listExample.add(new Example("Example name6", 7, "Example detail 1", "Example detail 2", R.drawable.7_icon, "Example detail 3")); listExample.add(new Example("Example name7", 8, "Example detail 1", "Example detail 2", R.drawable.8_icon, "Example detail 3")); listExample.add(new Example("Example name8", 9, "Example detail 1", "Example detail 2", R.drawable.9_icon, "Example detail 3")); listExample.add(new Example("Example name9", 10, "Example detail 1", "Example detail 2", R.drawable.10_icon, "Example detail 3")); } This is the code for the clicklistener. ListView list = (ListView) findViewById(R.id.exampleListView); list.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { Example clickedexample = listExample.get(position); startActivity(new Intent("com.example.app.EXAMPLEACTIVITY")); } } Is there any way I can get the information from clickedExample and set the textViews and imageView in ExampleActivity depending on which one was clicked?

  • jsFunction pass data to backingbean

    - by deilig
    I have a javascript that is calling a function addData(param1,param2,param3,param4) which is calling addClip at the end And I need to pass those to a backing bean. <a4j:form> <a4j:jsFunction name="addClip" action="#{backingBean.goGo}"> <a4j:actionparam name="param1" assignTo="#{backingBean.param1}"/> </a4j:jsFunction> </a4j:form> But I can't seem to pass any values to the backingbean. I've even tried setting a static value for the actionparam. But when I try to do a Systemout on the setParam1 method it only prints out null. Have I missed anything important?

  • standardize international phone no. code using only regex

    - by DarkFox
    Sipdroid on Android has a search & replace method, that uses regex. I'm trying to use it to make sure all outgoing calls has a country code in the format 00XX I also want it to put 0045 in front of the number, if no country code is present. The first one, I have solved, but I can't figure out how to do the second thing. Search: \A(((\+)(\d{2})?)|(00(\d{2})?)|)((\d|\s)+)\Z Replace: 00$4$6$7 I'm using http://www.regexplanet.com/simple/index.html to test it, with the test strings: "12345678", "+4512345678" and "004512345678" They should all return "004512345678".

  • Spring bean's DESTROY-METHOD attribute [does not work for me]

    - by EugeneP
    Can get work the attribute "destroy-method". First, even if I type non-existing method name into "destroy-method" attribute, Spring initialization completes fine (already strange!). Next, when a bean has a "prototype" scope, then I suppose it must be destroyed before the application is closed. That not happens, it is simply never called in my case. Though, after extracting this bean I can call this method explicitly and it does its job. Could you explain why this method is never called in my Spring 2.5 case? p.s. The method exists, it is public and has no arguments.

  • how to detect an IMAPMessage is not an email but a Task or Calendar item

    - by raticulin
    I am accessing Lotus and Groupwise using javamail via IMAP, recursively accessing all folders and processing email I find. But in folders like Tasklist and Calendar (those are from Groupwise but I think I remember Lotus had similar things), I get the items in there as instances of IMAPMessage, and so they are processed as if they were mail. I understand those items get exposed as mail through the IMAP protocol (either by design or by mistake), but I only want to process proper mail. Is there a way to do this? I have dismissed following approaches so far: Make sure the message has a message-id, at least in Groupwise Calendar items have it. Ignore folders by name (such as Calendar and Tasklist): is not totally correct as a user can move mail inside those folders. What I am looking is some IMAP api call I have missed so far or something in those lines...

  • Spring ROO issue with UrlRewrite in STS (eclipse)

    - by user224270
    I'm having trouble figuring out how to solve this issue. I have a file called: "urlrewrite.xml" which was automatically generated by spring ROO after running the "controller" command in ROO Shell. However, I still get the following error: "Referenced file contains errors (http://tuckey.org/res/dtds/urlrewrite3.0.dtd). For more information, right click on the message in the Problems View and select "Show Details..." Here's the content of the urlrewrite.xml file: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE urlrewrite PUBLIC "-//tuckey.org//DTD UrlRewrite 3.0//EN" "http://tuckey.org/res/dtds/urlrewrite3.0.dtd"> <urlrewrite default-match-type="wildcard"> <rule> <from>/resources/**</from> <to last="true">/resources/$1</to> </rule> <rule> <from>/static/WEB-INF/**</from> <set type="status">403</set> <to last="true">/static/WEB-INF/$1</to> </rule> <rule> <from>/static/**</from> <to last="true">/$1</to> </rule> <rule> <from>/</from> <to last="true">/app/index</to> </rule> <rule> <from>/app/**</from> <to last="true">/app/$1</to> </rule> <rule> <from>/**</from> <to>/app/$1</to> </rule> <outbound-rule> <from>/app/**</from> <to>/$1</to> </outbound-rule> </urlrewrite> Any thoughts on how to get rid of this error?

  • JSF: how to update the list after delete an item of that list

    - by Harry Pham
    It will take a moment for me to explain this, so please stay with me. I have table COMMENT that has OneToMany relationship with itself. @Entity public class Comment(){ ... @ManyToOne(optional=true, fetch=FetchType.LAZY) @JoinColumn(name="REPLYTO_ID") private Comment replyTo; @OneToMany(mappedBy="replyTo", cascade=CascadeType.ALL) private List<Comment> replies = new ArrayList<Comment>(); public void addReply(NewsFeed reply){ replies.add(reply); reply.setReplyTo(this); } public void removeReply(NewsFeed reply){ replies.remove(reply); } } So you can think like this. Each comment can have a List of replies which are also type Comment. Now it is very easy for me to delete the original comment and get the updated list back. All I need to do after delete is this. allComments = myEJB.getAllComments(); //This will query the db and return updated list But I am having problem when trying to delete replies and getting the updated list back. So here is how I delete the replies. Inside my managed bean I have //Before invoke this method, I have the value of originalFeed, and deletedFeed set. //These original comments are display inside a p:dataTable X, and the replies are //displayed inside p:dataTable Y which is inside X. So when I click the delete button //I know which comment I want to delete, and if it is the replies, I will know //which one is its original post public void deleteFeed(){ if(this.deletedFeed != null){ scholarEJB.deleteFeeds(this.deletedFeed); if(this.originalFeed != null){ //Since the originalFeed is not null, this is the `replies` //that I want to delete scholarEJB.removeReply(this.originalFeed, this.deletedFeed); } feeds = scholarEJB.findAllFeed(); } } Then inside my EJB scholarEJB, I have public void removeReply(NewsFeed comment, NewsFeed reply){ comment = em.merge(comment); comment.removeReply(reply); em.persist(comment); } public void deleteFeeds(NewsFeed e){ e = em.find(NewsFeed.class, e.getId()); em.remove(e); } When I get out, the entity (the reply) get correctly removed from the database, but inside the feeds List, reference of that reply still there. It only until I log out and log back in that the reply disappear. Please help

  • Which thread invokes SensorEventListener.onSensorChanged

    - by Christoph Heindl
    From my records it seems that SensorEventListener.onSensorChanged callback is called by the same thread that registered the callback. I.e there must be some message-queue synchronization going on in the background which allows the activitys UI-Thread to handle the callbacks. That leads to my question: Is there a need to synchronize SensorEventListener.onSensorChanged with the activitys UI-thread, assuming that the activitys UI-thread registered the SensorEventListener? I cannot find any documentation references, but can see various examples calling invalidate() unsychronized or synchronize the entire callback. I used something along the lines of Log.i(TAG, "" + Thread.currentThread().getId()); to retrieve threading information. I'm running android 2.1 update1. Best regards, Christoph

  • Losing sessions on GlassFish

    - by synti
    I have a web application that logs users in a @SessionScoped managed bean. It's all the basic stuff, pretty much like this: users logs in using regular http form and gets redirect to user area (wich is protected using a filter). But if any resource on that area is accessed, the request somehow uses a new session, wich has no managed bean, no user, and the filter does his job, redirecting him to login page. Here's the login form: <h:form> <h:outputLabel for="email" value="Email "/> <p:inputText id="email" size="30" value="#{loginManager.email}"/> <h:outputLabel for="password" value="Password "/> <p:password id="password" size="12" value="#{loginManager.password}"/> <p:commandButton value="Login" action="#{loginManager.login()}"/> </h:form> The loginManager managed bean: @ManagedBean @SessionScoped public class LoginManager implements Serializable { @EJB private UserService userService; private User user; private String email; private String password; public String login() { user = userService.findBy(email, password); if (user == null) { // FacesMessage stuff } else { return "/user/welcome.xhtml?faces-redirect=true"; } } public String logout() { FacesContext.getCurrentInstance().getExternalContext().invalidateSession(); return "/index.xhtml?faces-redirect=true"; } // Getters, setters (no setter for user) and serialVersionUID And then comes the filter that protects the user area: @WebFilter(urlPatterns="/user/*", displayName="UserFilter") public class UserFilter implements Filter { @Override public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { HttpSession session = ((HttpServletRequest)request).getSession(false); LoginManager loginManager = (LoginManager) session.getAttribute("loginManager"); if (loginManager == null || !loginManager.hasUser()) { HttpServletResponse resp = (HttpServletResponse) response; resp.sendRedirect("index.xhtml"); } final User user = loginManager.getUser(); if (user.isValid()) { chain.doFilter(request, response); } else { HttpServletResponse resp = (HttpServletResponse) response; resp.sendRedirect("index.xhtml"); } } The UserService is just a stateless EJB that handles persistence. Part of the JSF for user area: <h:form> <p:panelMenu> <p:submenu label="Items"> <p:menuitem value="Add item" action="#{userItens.addItems}" ajax="false"/> <p:menuitem value="My items" /> </p:submenu> </p:panelMenu> </h:form> And finally the userItens managed bean. @ManagedBean @RequestScoped public class UserItens { private User user; @PostConstruct private void init() { HttpSession session = (HttpSession) FacesContext.getCurrentInstance() .getExternalContext().getSession(false); LoginManager loginManager = (LoginManager) session.getAttribute("loginManager"); if (loginManager != null) user = loginManager.getUser(); } public String addItems() { // Doesn't get here. Seems like UserFilter comes first, doesn't find // an user and redirects. } I'm using glassfish and session timeout is now on 0.

  • Is it better to use List or Collection?

    - by Vivin Paliath
    I have an object that stores some data in a list. The implementation could change later, and I don't want to expose the internal implementation to the end user. However, the user must have the ability to modify and access this collection of data. Currently I have something like this: public List<SomeDataType> getData() { return this.data; } public void setData(List<SomeDataType> data) { this.data = data; } Does this mean that I have allowed the internal implementation details to leak out? Should I be doing this instead? public Collection<SomeDataType> getData() { return this.data; } public void setData(Collection<SomeDataType> data) { this.data = new ArrayList<SomeDataType>(data); }

  • Spring bean creation via deserialization

    - by mdma
    Spring has many different ways of creating beans, but is it possible to create a bean by deserializing a resource? My application has a number of Components, and each manipulates a certain type of data. During test, the data object is instantiated directly and set directly on the component, e.g. component.setData(someDataObject). At runtime, the data is available as a serialized object and read in from the serialized stream by the component. Rather than having each component explicitly deserialize it's data from the stream, it would be more consistent and flexible to have Spring deserialize the data object from a resource. Is there a DeserializerBeanFactory or something similar?

  • Why encodeXxx methods in UIComponent accept FacesContext parameter?

    - by Roman
    I haven't ever before created custom component in jsf so I've noticed it only now that methods like encodeBegin(), encodeEnd() etc accept FacesContext parameter. FacesContext instance can usually be received with FacesContext.getCurrentInstance(). So, I wonder whether these methods have FacesContext parameter just for convenience or some different objects can be passed there (maybe from external resources..). If the latter is possible then could you give an example pls.

  • eclipse add unimplemented methods including javadoc

    - by dcp
    When implementing an interface in eclipse, it has a really nice feature that lets you "add unimplemented methods", and it will generate the method stubs for the interface methods. However, it does not bring along the method documentation from the interface methods, and I was wondering if there was a way to get eclipse to do that.

  • Eclipse and Cassandra

    - by H2oNinja
    I've searched various websites for instructions on how to link 'Cassandra' and 'Eclipse' and followed directions to the last detail in several sites. For some reason, while using Git Bash, I cant get through the 'ant build', via instruction in said mentioned locations across the web. In some location's its easy, just make sure you have; 1. Apache Cassandra source 2. Apache Ant 3. Git So, yeah I've downloaded all the above, tried the same directory, different directories, etc., although still unable to get past the middle step of 'ant build'. Here are a few websites I've used to muddle through setting up the Src code for both utilities, 'Eclipse' and 'Cassandra'. http://uisurumadushanka89.blogspot.com/2012/02/apache-cassandra-how-to-setup-source.html and http://wiki.apache.org/cassandra/RunningCassandraInEclipse both resulting in an immediate halt at the 'ant build'. any insights are information is greatly appreciated. Thank-you, Ryan

  • Replacing ORM schema without dropping the entire data

    - by Udi
    Hey, I'm using OpenJPA as a JPA provider. Is there a way in which I can recreate the database tables (When an entity changes) without dropping the entire data? When an entity changes, I drop and create every table in the store, and obviously lose the data within. Is there a tool or product to keep the data somehow? Thanks, Udi
