示例1: onTouchEvent
import android.support.v7.widget.RecyclerView; //导入方法依赖的package包/类
@Override
public void onTouchEvent(RecyclerView rv, MotionEvent e) {
debugLog("onTouchEvent");
if ((e.getAction() == MotionEvent.ACTION_UP) ||
(e.getAction() == MotionEvent.ACTION_CANCEL)) {
if ((e.getAction() == MotionEvent.ACTION_UP) && selectedDragItemPos != -1) {
int newPos = getNewPostion(rv);
if (moveInterface != null)
moveInterface.onItemMoved(selectedDragItemPos, newPos);
}
setIsDragging(false);
selectedDragItemPos = -1;
floatingItem = null;
rv.invalidateItemDecorations();
return;
}
fingerY = (int) e.getY();
if (floatingItem != null) {
floatingItemBounds.top = fingerY - fingerOffsetInViewY;
if (floatingItemBounds.top < -floatingItemStatingBounds.height() / 2) //Allow half the view out the top
floatingItemBounds.top = -floatingItemStatingBounds.height() / 2;
floatingItemBounds.bottom = floatingItemBounds.top + floatingItemStatingBounds.height();
floatingItem.setBounds(floatingItemBounds);
}
//Do auto scrolling at end of list
float scrollAmount = 0;
if (fingerY > (rv.getHeight() * (1 - autoScrollWindow))) {
scrollAmount = (fingerY - (rv.getHeight() * (1 - autoScrollWindow)));
} else if (fingerY < (rv.getHeight() * autoScrollWindow)) {
scrollAmount = (fingerY - (rv.getHeight() * autoScrollWindow));
}
debugLog("Scroll: " + scrollAmount);
scrollAmount *= autoScrollSpeed;
rv.scrollBy(0, (int) scrollAmount);
rv.invalidateItemDecorations();// Redraw
