我要显示在列表视图中长preSS的Andr​​oid语境动作模式

那么有没有办法来处理这​​个问题。

在计算器搜索后
我发现我的答案使用此问题
在我的列表视图实现GestureDetector的这里是我的code

After search on stackoverflow i found my answer using this question implement GestureDetector on my listview an here is my code

在列表视图设置GestureDetector

set GestureDetector on listview

final GestureDetector gestureDetector = new GestureDetector(new MyGestureDetector());
        View.OnTouchListener gestureListener = new View.OnTouchListener() {
            public boolean onTouch(View v, MotionEvent event) {
                return gestureDetector.onTouchEvent(event); 
            }};
        mMessageListView.setOnTouchListener(gestureListener);

和MyGestureDetector这个code

and this code of MyGestureDetector

class MyGestureDetector extends SimpleOnGestureListener{ 

           @Override
        public void onLongPress(MotionEvent e) {
            super.onLongPress(e);
            ListView lv = mMessageListView;
            int pos = lv.pointToPosition((int)e.getX(), (int)e.getY());
            if (listMsg.get(pos).type==ChatItem.ITEM) {
                mMessageListView.setItemChecked(pos, !adapter.isPositionChecked(pos));
            } 
        }

       }
