现在我用的：

android:listSelector="@drawable/bg_list_item"
android:drawSelectorOnTop="true"

在这里bg_list_item.xml：

where bg_list_item.xml:

<?xml version="1.0" encoding="utf-8"?>

<item android:state_selected="true">
    <shape android:shape="rectangle">
        <gradient android:startColor="#0000ff"/>
    </shape>
</item>

<item android:state_focused="false"
      android:state_pressed="false"
      android:state_selected="false">
    <shape android:shape="rectangle">
        <gradient android:startColor="#ff0000"/>
    </shape>
</item>

但第一项不工作，选择的项目是不是有时滚动高亮（当我接近我的列表视图顶部/底部），从来没有在listView.setSelection（指数）。

BUT first item is not working and selected item is not highlighting sometimes on scroll (when I am near top/bottom of my listview) and never on listView.setSelection(index).

难道我一定要强调当前项目programmaticaly？

Does I must to highlight current item programmaticaly?

推荐答案

定义一个定制适配器，并在其getView（）方法：

define a custom adapter and in its getView() method:

private int selectedItem;

// is used outside the adapter for example OnItemClickListener
public void setSelectedItem(int position) {
    selectedItem = position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
   //...
   // set selected item
    LinearLayout activeItem = (LinearLayout) rowView;
    if (position == selectedItem)
    {
       activeItem.setBackgroundResource(R.drawable.background_dark_blue);
    }
    else
    {
       activeItem.setBackgroundResource(R.drawable.border02);
    }
   //...
}
