问题描述

在我的活动中，我引用了 ScrollView.根据要求，我应该禁用ScrollView的惯性滚动.我该怎么做?

In my activity I reference ScrollView. According to the requirements, I should disable the inertial scrolling of ScrollView. How can I do that?

推荐答案

这些对我有用，但我不确定它是否对性能有好处.

These worked form me, but I'm not sure if it is good for performance.

我所做的是创建一个扩展 ScrollView 的新视图并覆盖 onTouchEvent 方法:

What I did was create a new View extending the ScrollView and override the onTouchEvent method:

@Override
public boolean onTouchEvent(MotionEvent ev) {


    switch (ev.getAction()){
        case ACTION_UP:

            return false;
        default:
            return super.onTouchEvent(ev);
    }
}

也许，您还应该检查 ScrollView 的源代码以检查是否还有其他重要的事情要做.

perhaps, you should also check the source code of the ScrollView to check if there is anything important else to do.

这里有你可以使用的源代码:

Here you have the source code at dispose:
