Answer 1

尝试将标题 View 添加到 ListView 中(在这种情况下标题也会滚动)，您需要在 MainActivity 中执行以下操作:

View header = (View) getLayoutInflater().inflate(
            R.layout.header_layout, null);
ImageView img=(ImageView)header.findViewById(R.id.imgView);
img.setBackgroundResource(R.drawable.icon);
mainListView.addHeaderView(header);

或者您可以使用 DesignLibrary，例如 here或here .
