我想设置列表的背景颜色，它在文本框中具有不同的值，如来自数据库的快乐，悲伤，我希望在我的文本框中快乐时，背景颜色变为红色，生气时变为绿色像这样...
这是我的代码......

super.onPreExecute();

pDialog.show();

答案 0 :(得分：0)
在自定义适配器（SimpleAdapter）类中 - ＆gt;得到 - ＆gt;公共视图getView方法确保您的代码是使用此
View vi = convertView;
final ViewHolder holder;
try {
if (convertView == null) {
vi = inflater.inflate(R.layout.my_group_list_item, null);
holder = new ViewHolder();
vi.setTag(holder);
} else {
holder = (ViewHolder) vi.getTag();
}
if (if sad if happy clause here ) {
vi.setBackgroundColor(Color.parseColor("#a1cc3b"));
} else {
vi.setBackgroundColor(Color.parseColor("#cfd0d1"));
}
希望这可以帮到你。
