Restrict image loading while list scrolling

[gbrbks]

Hello!

The library is great but I have a question. Is it possible to restrict the image loading in listview just for the state of scroll idle state. So prevent loading when scrolling to boost up performance.

Thank in advance!

Best Regards.

Hi, I have just ended "Delay before image loading" feature and I'm working on class-helper exactly for your purpose. Will be very soon.

Thank you very much for the quick reply!

Look into OnScrollSmartOptions, it used in example project. Also I'll think about adding functionality to pause/resume ImageLoader while scrolling.

Awesome!

Just for clearence, the images will start loading in once the delay ended, right? I want to fully cancel the effect, and prevent them from loading. So i intend to skip the image loading phase while the scrolling is imminent, and start the loading (only the visible ones) once it stopped and the scroll state changed back to idle. This would be very helpful.

Thanks in advance!

smartOptions = new OnScrollSmartOptions(options, 999999, 999999, touchListener.makeScrollListener());
(999999 is ~16 min)
i used this setting but the image popped up almost instantly in Galaxy S3 (4.0.4) and Droid2 (2.3.3) while scrolling

sorry i didn't used the smartOptions.getOptions() method in the displayImage.
But in this case when the list is idle it didnt start to get the image just when delay ended.

I'm working on it.

Added ImageLoader.pause() and ImageLoader.resume() methods. And PauseOnScrollListener, look into example project.

Where can I see PauseOnScrollListener example project?

In sample project. ImageListActivity, ImageGridActivity.

Hi,
On scroll of the listView the images that are in listview row position are wrong one , but later it will load with the correct one. How i can fix this, I have used ViewHolder static class as given in the sample.

Thanks,
Sanjay

@SanjayKMath late, but just in case, you can try to set a default image after getTag() in the getView() function
