我能够明智地显示所有数据日期位置和....一起但我想过滤数据 - 日期明智的位置意味着如果我们检查位置明智然后它应该打印位置只有过滤器日期明智它应该显示日期..在列表请帮助我累了多少但无法做到这一点....我已经创建复选框选择日期明智过滤器，位置明智过滤所以请检查我的代码，如果你想我可以发送完整的代码。< / p>

如果您使用EditText进行搜索，那么您必须编写自己的过滤方法。这里有一个示例Custom ListView Search。
你必须改变filter这样的方法。
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
worldpopulationlist.clear();
if (charText.length() == 0) {
worldpopulationlist.addAll(arraylist);
} else {
for (WorldPopulation wp : arraylist) {
if(isDate)
{
if (wp.getDate().toLowerCase(Locale.getDefault()).contains(charText))
{
worldpopulationlist.add(wp);
}
}else{
if(wp.getLocation().toLowerCase(Locale.getDefault()).contains(charText))
{
worldpopulationlist.add(wp);
}
}
}
}
notifyDataSetChanged();
}
