如何使用overscroll功能的列表视图? [英] how to use overscroll functionality for listview?
问题描述
Android的新Overscroll功能姜饼介绍并发现了一些更有趣的事情。 该功能使AA视图滚动超出了它的极限,然后反弹(几乎完全一样的iOS)之类的内置的框架,但只是被隐藏了。

您可以试试这个它给。您的问题的解决方案。
滚动视图=(滚动型)findViewById(R.id.scr);
内容查看=(ViewGroup中)findViewById(R.id.r2);
scrollView.setOnTouchListener(新ScrollPager(滚动视图,内容查看));
scrollView.post(新的Runnable(){
公共无效的run(){
scrollView.scrollTo(0,contentView.getPaddingTop());
}
});
为此,你需要的scroolerPager类。它来到这里,
公共类ScrollPager实现OnTouchListener
公共ScrollPager(滚动型aScrollView,ViewGroup中aContentView)
{
mScrollView = aScrollView;
mContentView = aContentView;
滚动=新的滚轮(mScrollView.getContext(),新OvershootInterpolator());
任务=新的Runnable()
{
公共无效的run()
{
scroller.computeScrollOffset();
mScrollView.scrollTo(0,scroller.getCurrY());
如果(!scroller.isFinished())
{
mScrollView.post(本);
}
}
};
}
Android's new Overscroll functionality introduced in Gingerbread and discovered some more interesting things. The functionality to make a a view scroll beyond its limits and then bounce back (almost exactly like iOS) is sort of built into the framework, but just hidden.

You can try this it give. you the solution for your problem.
scrollView = (ScrollView) findViewById(R.id.scr);
contentView = (ViewGroup) findViewById(R.id.r2);
scrollView.setOnTouchListener(new ScrollPager(scrollView, contentView));
scrollView.post(new Runnable() {
public void run() {
scrollView.scrollTo(0, contentView.getPaddingTop());
}
});
for this you need the scroolerPager Class. get it here,
public class ScrollPager implements OnTouchListener
public ScrollPager(ScrollView aScrollView, ViewGroup aContentView)
{
mScrollView = aScrollView;
mContentView = aContentView;
scroller = new Scroller(mScrollView.getContext(), new OvershootInterpolator());
task = new Runnable()
{
public void run()
{
scroller.computeScrollOffset();
mScrollView.scrollTo(0, scroller.getCurrY());
if (!scroller.isFinished())
{
mScrollView.post(this);
}
}
};
}
