我正在开发一个商店列表中列表视图的应用程序。我需要的，当我的列表视图项目轻扫到右（或左），这个项目应该从列表视图中删除。

I am developing an application with a shop list in a listview. I need that when I swipe the item of listview to the right(or left), this item should get deleted from the listview.

我有我的列表视图，只需要功能做到这一点。

I have my listview and only need the function to do it.

在此先感谢。

这是怎么实现这种效果。我们有一个ListView lvSimple，我们onTouchListener添加到我们的lvSimple。这是我的工作code。

This is how I realize this effect. We have a ListView lvSimple and we add onTouchListener to our lvSimple. This is my working code.

float historicX = Float.NaN, historicY = Float.NaN;
static final int DELTA = 50;
enum Direction {LEFT, RIGHT;}
...
ListView lvSimple = (ListView) findViewById(R.id.linLayout);
...
lvSimple.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) 
    {
        // TODO Auto-generated method stub
        switch (event.getAction()) 
        {
            case MotionEvent.ACTION_DOWN:
            historicX = event.getX();
            historicY = event.getY();
            break;

            case MotionEvent.ACTION_UP:
            if (event.getX() - historicX < -DELTA) 
            {
                FunctionDeleteRowWhenSlidingLeft();
                return true;
            }
            else if (event.getX() - historicX > DELTA)  
            {
                FunctionDeleteRowWhenSlidingRight();
                return true;
            } break;
            default: return false;
        }
        return false;
    }
});

其中函数FunctionDeleteRowWhenSlidingLeft（）时，当我们滑动到左侧，FunctionDeleteRowWhenSlidingRight主叫 - 分别在右侧。在这个功能，你需要粘贴code动画。

where function FunctionDeleteRowWhenSlidingLeft() is calling when when we sliding to the left, FunctionDeleteRowWhenSlidingRight - to the right respectively. In this function you need paste code for animation.
