               return true;            }        });

MyGestureDetector类

public class MyGestureDetector extends SimpleOnGestureListener {    @OverrIDe    public voID onLongPress(MotionEvent e) {        super.onLongPress(e);    }}

帮帮我..谢谢

解决方法:

我认为,无需使用SimpleOnGestureListener.

在您的自定义适配器视图中：

第一,

eventTitleVIEw.setFocusable(false); eventTitleVIEw.setFocusableIntouchMode(false);eventTitleVIEw.setLongClickable(true);eventDescVIEw.setFocusable(false); eventDescVIEw.setFocusableIntouchMode(false);eventDescVIEw.setLongClickable(true);eventDateVIEw.setFocusable(false); eventDateVIEw.setFocusableIntouchMode(false);eventDateVIEw.setLongClickable(true);

然后,
只需将eventTitleVIEw,eventDescVIEw和eventDateVIEw的setonLongClickListener(VIEw.OnLongClickListener l)设置为

eventTitleVIEw.setonItemLongClickListener(new OnItemLongClickListener() {        public boolean onItemLongClick(AdapterVIEw<?> parent, VIEw vIEw, int position, long ID) {            //do your sorting stuff here        }    });eventDescVIEw.setonItemLongClickListener(new OnItemLongClickListener() {        public boolean onItemLongClick(AdapterVIEw<?> parent, VIEw vIEw, int position, long ID) {            //do your sorting stuff here        }    });eventDateVIEw.setonItemLongClickListener(new OnItemLongClickListener() {        public boolean onItemLongClick(AdapterVIEw<?> parent, VIEw vIEw, int position, long ID) {            //do your sorting stuff here        }    });

希望这对您有所帮助.
