    I have the following setup, and the empty view text doesn't show up... protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); getListView().setEmptyView(findViewById(R.id.empty)); getListView().setTextFilterEnabled(true); setListAdapter(null);// to have empty list } The layout file is: <?xml version="1.0" encoding="utf-8"?> <LinearLayout android:id="@+id/myScrollLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" xmlns:android="http://schemas.android.com/apk/res/android"> <FrameLayout android:layout_width="fill_parent" android:layout_height="0dip" android:layout_weight="1"> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false" /> <!-- Here is the view to show if the list is emtpy --> <ScrollView android:id="@android:id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent"> <TextView android:id="@+id/emptyText" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/contact_empty_help" android:textSize="20sp" android:textColor="?android:attr/textColorSecondary" android:paddingLeft="10dip" android:paddingRight="10dip" android:paddingTop="10dip" android:lineSpacingMultiplier="0.92" /> </ScrollView> </FrameLayout> </LinearLayout> String is defined as: <string name="contact_empty_help">"You don't have any contacts to display.\n\nTo add contacts, you have to:\n \n<li><font fgcolor="#ffffffff">Go to <b>Contacts</b></font> application to create new contacts\n</li> \n<li><font fgcolor="#ffffffff"><b>Import from VCF file</b></font>, this is available in Contacts menu, the file most be on the root of the SD card\n</li>" </string> Since the list is empty, it should show me the text defined.

  • dublicate display of Posts from controller - conditions and joins problem - Ruby on Rails

    - by bgadoci
    I have built a blog application using Ruby on Rails. In the application I have posts and tags. Post has_many :tags and Tag belongs_to :post. In the /views/posts/index.html view I want to display two things. First is a listing of all posts displayed 'created_at DESC' and then in the side bar I am wanting to reference my Tags table, group records, and display as a link that allows for viewing all posts with that tag. With the code below, I am able to display the tag groups and succesfully display all posts with that tag. There are two problems with it thought. /posts view, the code seems to be referencing the Tag table and displaying the post multiple times, directly correlated to how many tags that post has. (i.e. if the post has 3 tags it will display the post 3 times). /posts view, only displays posts that have Tags. If the post doesn't have a tag, no display at all. /views/posts/index.html.erb <%= render :partial => @posts %> /views/posts/_post.html.erb <% div_for post do %> <h2><%= link_to_unless_current h(post.title), post %></h2> <i>Posted <%= time_ago_in_words(post.created_at) %></i> ago <%= simple_format h truncate(post.body, :length => 300) %> <%= link_to "Read More", post %> | <%= link_to "View & Add Comments (#{post.comments.count})", post %> <hr/> <% end %> /models/post.rb class Post < ActiveRecord::Base validates_presence_of :body, :title has_many :comments, :dependent => :destroy has_many :tags, :dependent => :destroy cattr_reader :per_page @@per_page = 10 end posts_controller.rb def index @tag_counts = Tag.count(:group => :tag_name, :order => 'updated_at DESC', :limit => 10) @posts=Post.all(:joins => :tags,:conditions=>(params[:tag_name] ? { :tags => { :tag_name => params[:tag_name] }} : {} ) ).paginate :page => params[:page], :per_page => 5 respond_to do |format| format.html # index.html.erb format.xml { render :xml => @posts } format.json { render :json => @posts } format.atom end end

  • problem installing VS 2010 after uninstalling the RC

    - by rap-uvic
    Hi I uninstalled my VS 2010 RC to install VS 2010. However, it fails to install with the following error in the log files: d:\vs_setup.msi could not be opened. I've tried running the windows clean install and deleting any VS2010 files; also renamed the Microsoft Visual Studio 10.0 folder in the registry, but I keep getting the same error. I can see the vs_setup.msi on the dvd, it just won't allow me to run it directly. I have to run setup.exe. Any ideas?

  • How to Solve N-Queens Problem in Scheme?

    - by Philip
    Hi, I'm stuck on the extended exercise 28.2 of How to Design Programs. Here is the link to the question: http://www.htdp.org/2003-09-26/Book/curriculum-Z-H-35.html#node_chap_28 I used a vector of true or false values to represent the board instead of using a list. This is what I've got which doesn't work: #lang Scheme (define-struct posn (i j)) ;takes in a position in i, j form and a board and returns a natural number that represents the position in index form ;example for board xxx ; xxx ; xxx ;(0, 1) - 1 ;(2, 1) - 7 (define (board-ref a-posn a-board) (+ (* (sqrt (vector-length a-board)) (posn-i a-posn)) (posn-j a-posn))) ;reverse of the above function ;1 - (0, 1) ;7 - (2, 1) (define (get-posn n a-board) (local ((define board-length (sqrt (vector-length a-board)))) (make-posn (floor (/ n board-length)) (remainder n board-length)))) ;determines if posn1 threatens posn2 ;true if they are on the same row/column/diagonal (define (threatened? posn1 posn2) (cond ((= (posn-i posn1) (posn-i posn2)) #t) ((= (posn-j posn1) (posn-j posn2)) #t) ((= (abs (- (posn-i posn1) (posn-i posn2))) (abs (- (posn-j posn1) (posn-j posn2)))) #t) (else #f))) ;returns a list of positions that are not threatened or occupied by queens ;basically any position with the value true (define (get-available-posn a-board) (local ((define (get-ava index) (cond ((= index (vector-length a-board)) '()) ((vector-ref a-board index) (cons index (get-ava (add1 index)))) (else (get-ava (add1 index)))))) (get-ava 0))) ;consume a position in the form of a natural number and a board ;returns a board after placing a queen on the position of the board (define (place n a-board) (local ((define (foo x) (cond ((not (board-ref (get-posn x a-board) a-board)) #f) ((threatened?

  • WPF listbox : problem with selection

    - by KiTe
    Hello. In my XAML file, I have a ListBox declared like this : <ListBox x:Name="lstDeck" Height="280" ItemsSource="{Binding Path=Deck}" > <ListBox.ItemTemplate> <DataTemplate> <ListBoxItem Content="{Binding}" /> </DataTemplate> </ListBox.ItemTemplate> </ListBox> In my view model, Deck is an ObservableCollection, so that binding directly displays the content of my collection. But when I have several value that hold the same value (for example "10" six times), the selection in the ListBox has a weird behaviour : it select 2-3 elements instead of the only the one on which I clicked. Moreover, when I click to another listBoxItem, it doesn't unfocus the previous selected one. Then it is impossible to see which item is actually selected, and impossible to get the SelectedIndex value. Has someone an idea?

  • Git checking out problem [fatal: early EOFs]

    - by Style
    Dear all, I'm running a Ubuntu (9.10) server with Git (latest from Ubuntu package manager) installed. Access to the Git is via SSH. On windows machines, I'm using Cygwin to push/pull code. I can push my project code onto the server but when I do a clone or pull, it returns a [fatal: early EOFs] error at about 75-80%. Upon further investigation, it seems like textual data has no issue when pulled/cloned but when the jar files and images are pulled from Git, the error will occur. Any suggestion/advice that can help to resolve this issue? Thanks in advance.

  • Problem loading XMLDocument with non standard tags

    - by David Conde
    Hi, I have a code needed to load an XML document from a reader, something like this: private static XmlDocument GetDocumentStream(string xmlAddress) { var settings = new XmlReaderSettings(); settings.DtdProcessing = DtdProcessing.Ignore; settings.ValidationFlags = XmlSchemaValidationFlags.None; var reader = XmlReader.Create(xmlAddress, settings); document.Load(reader); return document; } But in my XML document, I have nodes like this one: <link rel="edit-media" title="Package" href="Packages(Id='51Degrees.mobi',Version='0.1.11.9')/$value" /> Is to my understanding that the node should be like <link rel="edit-media" title="Package"></link> But, I don't create the Xml document and I certainly don't want to change it, but when I try to load the XML document, the document.Load line throws an exception. To be more specific, the XML file is the RSS source for the nuPack project. Any ideas would be very appreaciated on how to be able to read this document properly.

  • Coda-Slider Problem in ie7, need to remove horizontal scrollbar

    - by Mike
    Hello, I am having a big issue with coda-slider and ie7. The horizontal scrollbar is unwanted and I cannot figure out how to remove it. Since coda-slider works as one long scrolling div, I could see why this is happening, however, in all other broswers, including ie8, there is no horizonal scroll. Looking through the web there are alot of sites saying "overflow-x:hidden" will work on the body selector in css, however this has not solved the issue. the site is at http://www.clearcreativegroup.com/clear3/index.html Any help would be greatly appreciated.

  • Problem -- My Android "Hello World" App Won't Say 'Hello"

    - by keith
    Hello, I hope that I have come to the right post for a beginner’s question abut Android programming. If not, please feel free to direct me to a better forum. I created a hello world application, and the system generated most of the Android language below. When running the app without the system.out statement, there is no “hello” in the emulator. Then, using the Eclipse tutorial, I read that I can add the system.out.println statement to main. Again the app runs, but there is no output. What am I not understanding here? android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="@string/hello" System.out.println =" Hello world!" / Thank you, Keith

  • Body Margin:0, Div Width:100% problem in FF and Chrome, fine in IE

    - by Albert
    Hey People, I'm starting to pull my hair out of my head... I have the following: <html> <head> <style> body { margin:0 auto; } </style> </head> <body> <div style="border: solid 1px red; width: 100%;">test</div> </body> </html> This works in IE producing a nice div, 100% width, no H scrollbar... Now in Chrome and FF, it is 1px wider than the window, causing an H scrollbar... Why is that? What SHOULD I be using instead? Thanks a lot! Albert

  • jQuery Drag/Drop problem: mousemove Event not binding for some elements

    - by saturdayplace
    Using the latest jQuery/UI that are hosted at Google. I've got the following markup: <ul id="tree"> <li><a href="1/">One</a></li> <li><a href="2/">Two</a></li> </ul> And the following javascript: $(document).ready(function(){ // Droppable callbacks function dragOver(overEvent, ui_object) { $(this).mousemove(function(moveEvent){ console.log("moved over", this); }); } function drop_deactivate() { $(this).unbind(); } function drag_out() { $(this).unbind(); } // Actual dragging $("#treeContainer li").draggable({ revert: true, revertDuration: 0 }); // Actuall dropping $("a").droppable({ tolerance: "pointer", over: dragOver, deactivate: drop_deactivate, out: drag_out }); }); If I drag the first li down over the second, the mousemove function fires (and firebug logs the output). But if I drag the second li up over the first, the mousemove function doesn't fire. You can see this live at http://jsbin.com/ivala. Is there a reason for this? Should I be trapping the mousemove event in some other way? Edit: It appears as thought the mousemove() event isn't binding for earlier elements than the one currently being dragged (should be bound upon their mouseover).

  • Problem using Winforms WebBrowser control as editor

    I am currently working on a project where I am using a WebBrowser control as an editor. I have design mode turned on and it seems to be working. The issue im having is when I try to save the Document and load another it pops up the "This document has been modified." message. What I am trying to do is as simple as this if (frontPage) { frontPage = false; frontContent = webEditor.DocumentText; webEditor.DocumentText = backContent; } else { frontPage = true; backContent = webEditor.DocumentText; webEditor.DocumentText = frontContent; } Like I said everytime I enter some text and run this code it just pops up a message saying its been modified and asks if I want to save. How can I get around this?
