问题描述
我在这是一个下拉刷新列表视图，但它呈现出奇怪的错误，每当我试图在我的银河S3运行一个自定义列表视图的工作，它开始说
I /编舞（698）：跳过340帧！该应用程序可能会做它的主线程的工作太多了。
和列表视图的滚动是痛苦的缓慢。附件是在S3上测试和HTC设备的视频和它的作品完美的HTC。任何指针，之所以会出现这种情况？

解决方案有关的任何其他人，面临着同样的还挺发给你将不得不寻找一些地方使用的是大量的内存，在我的情况下，它是在图像列表视图这是造成这个问题，我已经更换为质量较低的之一，其做工精细图像现在，但它仍然超出了我如何做同样的列表视图效果更好下端设备，然后一个高端设备上。除了我。
I have worked on a custom list view which is a pull down to refresh listview but it is showing a strange error , whenever i try to run it on my galaxy s3 , it starts saying
I/Choreographer(698): Skipped 340 frames! The application may be doing too much work on its main thread.
and the scrolling of the listview is painfully slow. Attached is video of testing on s3 and an htc device and it works flawlessly on HTC. Any pointers that why is this happening?

解决方案For any one else , facing the same kinda issue you will have to look some where you are using a lot of memory , in my case it was the image in listview that was causing the issue , i have replaced the image with a lower quality one and its working fine now , But its still beyond me that how does same list view works better on a lower end device then a higher end device. Beyond me .
