推荐答案

您可以试试这个，不知道这是否会加快，但给它一个镜头。

You can try this, not sure if it will speed up, but give it a shot.

在充气后台线程布局。

Inflate the layout in a background thread.

View getView(int position, View convertView, ...) {
    View v;
    if (convertView == null) {
        Start a background thread to inflate your linearLayout. 
        Pass item data and view 'v' to it.

        v = inflate a simple dummy textview;
        return v;
    }
    set normal stuff to convertview here.
    return convertView ;
 }

在后台线程，

• 充气的LinearLayout中成'V'
• 设置中的所有数据。

• 然后在视图无效 v 。

v.postInvalidate();
