所以我已經達到了我的繩索，當談到這個黨 datePicker對話框，我正在與。我已經通過我的應用程序中的7 不同的活動，並且在我到達datePicker之前沒有遇到過單個 問題。我的問題包含兩個 元素：1）我的datePicker的dang標題顯示星期三， 0002年12月召喚。 datePicker本身正確顯示 ，但不是標題，並且我沒有改變標題 位。當您更改日期時，標題將更改爲正確的 信息，但......除外。2）看起來好像星期幾 已關閉（表示2011年2月22日星期一）。所以我 要發佈我的整個代碼在這個活動，如果任何人有 任何想法任何幫助，非常感謝。這個問題將出現在onCreateDialog或onPrepareDialog方法的 中。如果我需要刪除 任何其他無關的初始化方法，我會這樣做，但我會 喜歡驗證我不會在 此活動中的其他任何地方造成問題。datePicker問題，標題初始化很時髦

我也嘗試setTitle，但只有在日期改變之前才能運行。
非常感謝......我相信這不會是我在樹林的這個脖子上的最後一篇文章。我會重新研究一些，看看它會把我帶到哪裏。雖然我還沒有這樣做，你知道這是否會解決我正在經歷的時髦標題方面？ – FROSTYSMOOTH
我對你的問題的第一部分有點困惑。什麼不正確顯示在問題的＃1部分中？ –
當datePicker初始化關閉按鈕時，它會顯示：0002年12月31日星期三作爲標題直到日期改變，然後標題顯示正確的信息。 – FROSTYSMOOTH
