Images on the screen in the list update only after scrolling to the rank of the list instead of updating automatically after each image is uploaded (delayed image loading)

1. I started a lazy image loader to download images in drawListRow and passed the url of the image to download reference.

2. After downloading the respective bitmap in the lazy image loader, I cancelled the list (called by using a reference to the screen where images are to shoot) using a thread event as follows:

    UiApplication.getUiApplication().invokeLater(new Runnable() {
            public void run() {
                _list.invalidate();
            }
        });

But my images are updated on the screen until I scroll over the line in the list.  I also tried to use _list.invalidate (index) to invalidate each line once the image is drawn to this particular line, but it does work and does the same thing as _list.invalidate ().

I want the images to be updated without scrolling, and as soon as they are downloaded. How do I get there?

Valuable contributions will be highly appreciated.

UiApplication.getUiApplication () .invokeLater (new Runnable() {public void run() {_list.invalidate ();})            }        });

use invokeAndWait instead of invokeLater and check if it works or not?

  • KB2416427 is listed in the optional instead of KB2477244 updates if SilverLight is not installed

    Why optional updates don't show KB2416427 instead of KB2477244 when SilverLight is not installed?  This question requires that I have install KB2416427 before the major update of the KB2477244 can be detected and installed.  It ends with two versions of SilverLight, and the record of the previous version of Silverlight is removed only after restarting, but in the Add/Remove list the installed size is always like 40 MB instead of 20 MB.  If I install SilverLight manually after uninstalling SilverLight installed in the Add/Remove list size is 20 MB.  Can you please replace the optional update of KB2416427 with KB2477244 in Microsoft Update to avoid running through two facilities of SilverLight After uninstallation of SilverLight?

  • The printer screen is hungup with updates of product on the screen

    HP ENVY 5530 - use the printer without fail since 07/29/14. Noticed, yesterday, the printer screen shows: 'Check' product updates and it hangs just at this moment. This post was on the screen of the printer for about 24 hours now. I can always print test pages and documents of other software. But I would like to get the printer to check the updates successfully.

    Resolutions or suggestions for this problem?

    Solved my problem.

    What I did:

    uninstalled all the software associated with the envy of 5530

    unplugged the power cord from the wall and printer

    disconnect the USB cable from the printer

    downloaded the latest version of the software for the 5530 like on HP site

    installation of the software

    Connect the power cord to the wall outlet and the printer

    THIS PART IS IMPORTANT > lifted the top of the printer to expose the inside of the printer where the ink cartridges. This stage caused the error message to delete the printer.

    Then I plugged in the USB cable to the printer and the PC and the printer took over the installation of the software and drivers.

    Now the printer is in working condition.

    NOTE: After it was over. I saw on the screen of the printer that a product update has been active and completed successfully.

    HOPE THIS HELPS.

  • The computer is stuck on automatic updating when closing down.

    During execution of the closure procedure an automatic update starts and had not finished after many hours. Even if it says do not turn off or unplug, because the computer will turn off automatically, I had to do. Now when starting, it still considers that it is updated, and other programs do not work correctly. I need to start in safe mode to restore, because the system restore does not start. How that I start in safe mode? And why the automatic update is causing this problem? It's never happened before, so there must be a bug in the update, and I can't stop it starts up because it is automatic! Someone Please helpme!

  • The computer hangs at "Shutting Down... "only after the installation of the updates for Vista Ultimate x 64 Windows

    Hello.  Recently, I have reinstalled the 64 bit version of Windows Vista Ultimate on my computer.  I allow all automatic updates (worth about 450MO) and let it do its thing.  Afterwards, I had to reboot my computer.  He was going smooth until he hit the "Configuring updates... "or something like that.  The circle stopped going around smooth and pauses every second or two.  After about 30 minutes, he went to "Shutting down...". "and I let this go all night.  After 4 p.m., he was still at "Shutting down...". "therefore I kept the button and made a closed hard.  After that I started it up, it would get to the loading screen with the green bars that go everywhere.  It also was not smooth and stopping every second or two.

    After about 10 minutes of this, I restarted my computer again, and it still wouldn't work.  I tried to start in safe mode, but it would also stop during the loading of some drivers and not continue.  So I reinstalled Vista again and, of course, was able to get without updates.  I thought it may have been a one time thing, so I did the windows updates again.  This problem repeated itself.  So I reinstalled Vista and am refraining from doing the updates of windows.

    I restarted my computer without updates, and it goes well.  It is only after updates where it fails to turn it off and save.  No one knows what is the problem and if there is a solution to this?

    Hi JerryR9190

    Thanks for posting on the Microsoft Answers site

    Are you Vista to get Service Pack 1 automatically as well?
    If so, please try to download/install it yourself and see if that has any effect.

    Windows Photo Gallery.  How can I change the settings in the Windows Photo Gallery to automatically open the image without going to the index first?

    Additional information: there are 2 computers that I use on the first Gallery Photo of Windows will open the image and allow me to use the left and right buttons to scroll through the rest of the photos in the folder, that's what I want.

    On the 2nd computer when I open an image it will open the Windows Photo Gallery in an index with thumbnails of the displayed record.  How can I change so that it opens the same thing as the first computer?

    I did the following on both computers; Right-click on the image and select open with...--> choose the default program--> go--> Program Files, Windows Photo Gallery, but it will be open always differently on computer 2.

    Both computers use Windows Vista 32-bit.

  • a way to change the style lightbox - all viewers automatically update?

    Hi guys, im setting up a video portfolio site and I went initially to have several thumbnails on each page, each trigger, an album containing a video.

    at a later stage, I might want to change the size of the black box that surrounds the video (I think what its called the container), or add an image / change color etc...

    My question is, is there a way to set up as a model so that when I update one, they are all up to date?

    It worries me because I have about 40 vignettes, each link to an album.

    Thank you

    Hello

    If you change the size of a container of the widget HTML composition, Muse automatically updates the containers of other videos of lightbox that you used, as long as you used a single with triggers lightbox widget with multiple targets.

    However, I must tell you that muse will update the size of the container and not the positioning of the videos, so if you want to adjust the positions of the videos too, then you will need to do so individually.

    Hope this helps

    Kind regards
