  • Problem setting row backgrounds in Android Listview

    - by zchtodd
    I have an application in which I'd like one row at a time to have a certain color. This seems to work about 95% of the time, but sometimes instead of having just one row with this color, it will allow multiple rows to have the color. Specifically, a row is set to have the "special" color when it is tapped. In rare instances, the last row tapped will retain the color despite a call to setBackgroundColor attempting to make it otherwise. private OnItemClickListener mDirectoryListener = new OnItemClickListener(){ public void onItemClick(AdapterView parent, View view, int pos, long id){ if (stdir.getStationCount() == pos) { stdir.moreStations(); return; } if (playingView != null) playingView.setBackgroundColor(Color.DKGRAY); view.setBackgroundColor(Color.MAGENTA); playingView = view; playStation(pos); } }; I have confirmed with print statements that the code setting the row to gray is always called. Can anyone imagine a reason why this code might intermittently fail? If there is a pattern or condition that causes it, I can't tell. I thought it might have something to do with the activity lifecycle setting the "playingView" variable back to null, but I can't reliably reproduce the problem by switching activities or locking the phone. private class DirectoryAdapter extends ArrayAdapter { private ArrayList<Station> items; public DirectoryAdapter(Context c, int resLayoutId, ArrayList<Station> stations){ super(c, resLayoutId, stations); this.items = stations; } public int getCount(){ return items.size() + 1; } public View getView(int position, View convertView, ViewGroup parent){ View v = convertView; LayoutInflater vi = (LayoutInflater)getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); if (position == this.items.size()) { v = vi.inflate(R.layout.morerow, null); return v; } Station station = this.items.get(position); v = vi.inflate(R.layout.songrow, null); if (station.playing) v.setBackgroundColor(Color.MAGENTA); else if (station.visited) v.setBackgroundColor(Color.DKGRAY); else v.setBackgroundColor(Color.BLACK); TextView title = (TextView)v.findViewById(R.id.title); title.setText(station.name); return v; } };

  • JS framework with conditionally loaded fragments

    - by kjs3
    I'm doing a single-page, responsive, mobile first design. I found this article about conditionally loaded fragments but am wondering what the different js frameworks have build-in to handle this? I'm imagining the mobile version with a list view fragment that transitions to a show view fragment. A larger portal could just show both fragments and change the show fragment when items in the list are clicked. I'd love thoughts on what is available from the various frameworks, not an argument. Ember?, Angular?, etc. Maybe I'm missing it, but I'm not seeing the responsive fragments issue brought up in the various demos I've found so far.

  • Itty bitty ITTIA DB for Java Embedded Device Development

    - by hinkmond
    Here's a nice 3rd party itty-bitty database, called ITTIA DB, for Java Embedded and Mobile development See: ITTIA DB for Java Embedded Here's a quote: Java applications on mobile devices and other embedded systems can now leverage the robust shared access and data distribution features of ITTIA DB SQL with a new JDBC (Java Database Connectivity) driver released this week. This driver provides significant value for Java developers targeting embedded platforms such as QNX and Linux. Plus, it can exchange data with an Oracle back-end database. That's good if that's what you have on the back-end. Hinkmond

  • 3D touch "Minority Report" style interface - what platform gets me there the fastest?

    - by Ross Braden
    I'm working on a project that requires touch interface, though the use case is desktop more than mobile. Want to start out platform agnostic, not a mobile app. There will be gridwork type of 3D objects and diagraming being represented - think AutoCAD or Minority Report. Want to build a prototype that will have hooks into a database to represent the data. Any advice on what tools to use both for the design and the development of the functionality is greatly appreciated. Thanks!

  • Is it possible to develop apps with Kendo UI to submit to iOS App Store?

    - by Farshid
    The number of platforms I have to develops apps for is increasing and It brings me lots of stress to learn new technologies for each target platform. I found out that Telerik's Kendo UI is very good to build websites that look and feel native on mobile platforms (e.g. iOS and Android). My question is, is it possible to build HTML5 apps to deploy them on iTunes App Store and Google Play? Please note that I am eager to know the possibility of creating apps (complete apps bundled in standard format of Apple and Google for distribution in their respective mobile app markets) but not websites.

  • Find the closest palindrome number C#

    - by user294837
    Hi All, I am trying to create a console application that reads number from a file all underneath each other like so: 101 9 and then outputs into another file the closest palindrome number. So far what I have is not quite rightm i.e. I don't think I can put the class inside a method which is a bit more Java I was wandering if anyone could help at all? Thanks :) namespace PalidromeC { class Program { static public void Main(string[] args) { #region WriteAnswers try { StreamWriter sw = new StreamWriter("C://Temp/PalindromeAnswers.txt"); sw.WriteLine("Answers"); sw.Close(); }//try catch (Exception e) { Console.WriteLine("Exception: " + e.Message); }//catch #endregion #region ReadFile try { string numbers; StreamReader sr = new StreamReader("C://Temp/Palindrome.txt"); numbers = sr.ReadLine(); while (numbers != null) { Console.WriteLine(numbers); numbers = sr.ReadLine(); }//while sr.Close(); Console.ReadLine(); }//try catch (Exception e) { Console.WriteLine("Exception: " + e.Message); }//catch #endregion NearPalindromeFinder f = new NearPalindromeFinder(); int palindrome = f.findNearPalindrome(n); Console.WriteLine("Nearest Palindrome = " + palindrome); }//main public static void testFindNearestPalindrome(int n) { class NearPalindromeFinder { int findNearPalindrome(int start) { if (testPalindrome(start)) return start; else { int neg = start; int pos = start; for (int i = 0; i < start; i++) { if (testPalindrome(start-i)) { neg = start-i; break; }//if if (testPalindrome(start+i)) { pos = start+i; break; }//if }//for return (start == neg) ? pos : neg; }//else }//findNearPalindrome bool testPalindrome(int start) { if (start == 0 || start == 1) return true; String str = String.valueOf(start); String rev = new if (str.equals(rev)) return true; else return false; }//testPalindrome }//NearPalindromeFinder class }//testFindNearestPalindrome }//Program Class

  • Confused about GNU `sort(1)` of a numerical sub field

    - by Chen Levy
    I wish to sort a space separated table, with the numerical value that found on the 2nd field. I can assume that the 2nd field is always fooN but the length of N is unknown: antiq. foo11 girls colleaguing foo2 Leinsdorf Cousy foo0 Montgomeryville bowlegged foo1 pollack Chevrier foo10 ill-conceived candlebomb foo3 seventieths autochthony foo101 re-enable beneficiate foo100 osteometric I read man sort(1) and played with all sort of options. On my system I found the line: sort -n -k2.5 table to work. My question is why? According to the man page: -k, --key=POS1[,POS2] start a key at POS1, end it at POS 2 (origin 1) ... POS is F[.C][OPTS], where F is the field number and C the characterposition in the field. OPTS is one or more single-letter ordering options, which override global ordering options for that key. If no key is given, use the entire line as the key. So why sort -n -k2.4 table don't work and sort -n -k.5 does?
