LWUIT滚动跳跃问题 [英] LWUIT scroll jumping issue

问题描述

我需要在表单上显示唯一的组件-HTMLComponent.垂直滚动滚动条到达表单/组件的底部时，将跳回到表单的顶部.我需要防止这种情况.

I need to show the only component on the form - HTMLComponent. Reaching the bottom of the form/component while vertical scrolling scroll bar jumps back to the top of the form. I need to prevent this.

我试图打开/关闭窗体和HTMLComponent上的滚动，但是无论如何，如果有滚动条，它将从底部返回顶部.我也尝试过边框和框布局以及HTMLComponent的其他容器-没用.

I've tried to turn on/off scrolling on the form and HTMLComponent but anyway if there's a scroll bar - it will return to the top from the bottom. Also I've tried border and box layouts and additional container for HTMLComponent - no use.

有什么主意如何防止这种滚动问题?

Any ideas how to prevent such scrolling issue?

推荐答案

尝试一下(它对我有用-LWUIT 1.5):

Try this (it works for me - LWUIT 1.5):

htmlComponent.getComponentForm().setCyclicFocus(false);

如果获得NullPointerException，请在将HtmlComponent添加到表单后再调用它.

If you get a NullPointerException, call it after adding to the HtmlComponent to a form.
