我正在使用searchfilter来搜索gridview中的项目..，我在serchfilter上调用webservice。我正在使用多个适配器用于diffrent2服务。问题是当我搜索任何值时，我得到特定值，但是当我搜索另一个值时，我的gridview不清楚，新值没有显示。我做什么..，请帮助我。，谢谢...
答案 0 :(得分：1)
// Filter Class
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
_alluserlist.clear();
if (charText.length() == 0) {
_alluserlist.addAll(_alluserlist);
} else {
for (Object bean : _alluserlist) {
if (((AllBean) bean).getusername().toLowerCase(Locale.getDefault())
.contains(charText)) {
_alluserlist.add(bean);
}
}
}
notifyDataSetChanged();
actully我没有添加setfilter方法。通过在我的适配器中使用setfilter方法。代码将正常工作。并在您的活动中调用set filter。
