Scroller的使用
1、初始化Scroller
Scroller mScroller = new Scroller(context);
2、重写computeScroll()方法
@Override
public void computeScroll() {
if (mScroller.computeScrollOffset()) {
scrollTo(mScroller.getCurrX(), mScroller.getCurrY());
postInvalidate();
}
}
3、调用startScroll方法开始滑动
private void smoothScrollTo(int destX, int destY) {
int scrollX = getScrollX();
int scrollY=getScrollY();
int deltaX = destX - scrollX;
int deltaY = destY-scrollY;
mScroller.startScroll(scrollX, scrollY, deltaX, deltaY, 2000);
invalidate();
}
