ListView中设置变化的图片

下面是关键代码，希望需要的人能看懂！

ArrayList<HashMap<String, Object>> list = new ArrayList<HashMap<String, Object>>();

for (Friend friend : friendListByBBNo) {

HashMap<String, Object> bbMap = new HashMap<String, Object>();

bbMap.put("friendNickName", friend.getFriend_nick_name());

bbMap.put("friendBBNo", "(" + friend.getFriend_id() + ")");

setIcon(friend,bbMap);

list.add(bbMap);

}

private void setIcon(Friend friend, HashMap<String, Object> map) {

if (friend.getFriend_dv() == 1) {

map.put("friendIcon", R.drawable.box);

} else if (friend.getFriend_dv() == 2) {

map.put("friendIcon", R.drawable.tv);

} else if (friend.getFriend_dv() == 3) {

map.put("friendIcon", R.drawable.phone);

} else if (friend.getFriend_dv() == 4) {

map.put("friendIcon", R.drawable.pc);

} else {

map.put("friendIcon", R.drawable.h015);

}

}

listAdapter = new SimpleAdapter(this, list, R.layout.search_result, new String[] { "friendIcon",

"friendNickName", "friendBBNo" }, new int[] { R.id.icon_photo, R.id.list_result_name,

R.id.list_result_id });
