Comments for Random Thoughts On Coding http://codingjunkie.net Practical HowTo's On Software Development Fri, 11 May 2012 23:47:37 +0000 hourly 1 http://wordpress.org/?v=3.3.2 Comment on Android Drag and Drop (Part 2) by Philippe http://codingjunkie.net/android-drag-and-drop-part-2/comment-page-1/#comment-529 Philippe Fri, 11 May 2012 23:47:37 +0000 http://codingjunkie.net/?p=948#comment-529 Hello, Thank you for your article. It's very clear and helpful. The thing I'm working on revolves around being able to rearrange the order of a list of button (in a vertical LinearLayout). While I wanted to managed the droping of button outside of the list the same you do (with DragActionEnded flag), my code crash with a Java.Util .ConcurrentModificationException. It only happens when I have more than 2 buttons in my list. Is it something you've encountered (as in your code, every chessboardsquare try to bring back the piece to visible) ? Also, can you explain why the "containsDragable"boolean . Isn't the ACTION_DROP event only sent to the view that received the drop ? Thanks Hello,

Nice post regarding drag and drop. I have a quick question. Well you have implemented the this Drag and Drop using Android 4.x. You have any idea on how to implement this drag and drop in Android 2.2.

I was wondering if there was an alternative to this for API's under 11. This is because the game I am creating is for Android 2.2 and above (API 8).

I have not tried to confirm this myself, but in my own code the drag occurs between LinearLayout objects contained in a TableLayout. Hopefully this is some help. Could you provide a few more details on what you are trying to do? Thanks for commenting. Cheers, Bill Hi Jeshika,

The code examples aren't great for doing a copy/paste as it's got some of my own custom code mixed in. I think what will work best is if I take out my own code and make it more generic and post a few gists on github. Stay tuned and thanks for your patience. Cheers, Bill Hi,

Although the new methods in the Files class are significant improvement for copying and moving files, I find the solution for copying and moving directories disappointing also. But at least there is a reasonable option now, compared to what one would have to do before. Thanks for taking the time to comment. Cheers, Bill Vinícius,

Why does not Java add a CopyFileOptions.RECURSIVE? I think that's what everyone expected. And several times there's no need for more functionality than that (thus, we could expect every Java programmer in the world ending with a DirUtils, like you did). The CopyFileOptions.RECURSIVE method would also allow VM to be optimized to do operating system's bulk move operations, which are usually are very fast, much faster than moving file by file. Off course it's nice advance from previous Java versions and it's very a powerful feature to have a visitor, but the design pattern should be left for those who want a more elaborate approach over the directory tree, not for extremelly common operations such as copying, moving or reading a directory size.
