在Froyo上ListView随机IndexOutOfBoundsException

Question

我有一个有大量下载的应用程序,我收到了很多这个错误:

正如您在堆栈跟踪中看到的那样,我的代码跟踪中没有一行.为了重现这一点,我幸运地找到了一个带有Froyo(2.2 p7)的用户,我只是向下滚动了ListView代码中的一个.在一些随机时间之后,它只是冻结了这个例外.每次在不同的时间发生这种情况.

这是一个ListView与EndlessAdapter它后面,只是添加越来越多的行.显然我在进行"过度滚动"时会出现此错误,但我甚至无法想到解决此问题的方法.复制很难,但每次有近200名在线用户,如果他们不断收到此错误,他们最终将不再使用该应用程序.

任何帮助,将不胜感激.

编辑:与其他人有类似的问题EndlessAdapter.http://groups.google.com/group/cw-android/browse_thread/thread/4739ce05742841da/af59c779e99f5e23?lnk=gst&q=index#af59c779e99f5e23

但这不是EndlessAdapter错.这是android的错.

Answer 1

经过大量的时间检查android源代码而不理解这个错误我终于破解了它.

出现该问题与三星手机,他们有过滚动功能的不同实现方式,并且最终引发此例外,因为它试图选择一个页脚/头出界(即使没有页脚视图).

我使用的解决方案并不漂亮,但它会阻止此错误再次发生.

class MyFixedListView extends ListView {
    @Override
    protected void dispatchDraw(Canvas canvas) {
        try {
            super.dispatchDraw(canvas);
        } catch (IndexOutOfBoundsException e) {
            // samsung error
        }
    }
}

现在我使用此ListView实现,错误消失了.

我真的希望这能帮助任何使用无限适配器的人
