问题 - 使用两个日期时间选择器
我正在尝试使用两个日期和时间选择器（例如 fromdate 和 To date）来获取选定的日期。如果我选择 fromdate，我可以将 fromdate 获取到文本视图。但是如果我选择第二个日期选择器（todate）更新相同的文本视图（Fromdate textview）。

I'm trying to get selected dates using two date and time picker (like fromdate and To date). If I select fromdate I can get the fromdate to the textview. But if I select second datepicker (todate) update same textview (Fromdate textview).
