 <span style="font-size:18px;">今天需要做一个特效，点击条目，点击的条目跳转到屏幕中间位置，自己就写了一个代码，</span><p><span style="font-size:18px;">直接贴代码</span></p>convertView.setOnClickListener(new View.OnClickListener() {                @Override                public void onClick(View v) {                    int firstVisiblePosition = listview.getFirstVisiblePosition();                    int lastVisiblePosition = listview.getLastVisiblePosition();                    int i = (lastVisiblePosition - firstVisiblePosition) / 2;                    if (position > i) {                        listview.setSelection(position - i);                    }    Toast.makeText(getApplicationContext(), position + "    " + firstVisiblePosition + "       " + lastVisiblePosition, Toast.LENGTH_LONG).show();

github搞得有点混，就不贴地址了

跟新，上面的代码有点不友好，如果到底移动的太多了，就加了几个判断，还是贴上主要代码

  int firstVisiblePosition = list_good_category.getFirstVisiblePosition();            int lastVisiblePosition = list_good_category.getLastVisiblePosition();            i = (lastVisiblePosition-firstVisiblePosition)/2;            goodCategoryAdapter.changedSelect(position);            if (position<lastVisiblePosition-2||position>firstVisiblePosition+2){                if (position > i) {                    list_good_category.setSelection(i);                }else {                    list_good_category.setSelection(position-3);                }            }
