Android ListView 横向滑动删除 Item

注册ListView的onTouchListener()
具体代码如下：

listview.setOnTouchListener(new OnTouchListener() {
    float x,y,ux,uy;

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        // TODO Auto-generated method stub
        if(event.getAction()==MotionEvent.ACTION_DOWN){
            x=event.getX();
            y=event.getY();
        }
        if(event.getAction()==MotionEvent.ACTION_UP){
            ux=event.getX();uy=event.getY();
            int p1=store_history.pointToPosition((int)x, (int)y);
            int p2=store_history.pointToPosition((int)ux, (int)uy);
            if(p1==p2&&Math.abs(x-ux)>10){
                listviewadapter.getData().remove(p1);
                listviewadapter.notifyDataSetChanged();
            }
            return true;
        }
        return false;
    }
});
