Android - 一個對話框中的一個日期和兩個時間選擇器

Question

我想在一個對話框中有一個日期和兩個時間選擇器，我已經完成了它，但第二次（時間）獲得的值相同）。我已經放了一些'如果情況'來解決它，但沒有幫助。我得到（「2016/10/27 5:41 0:00），即使我選擇兩個」時間選擇器「的時間，我沒有得到第二個值或它複製第一個的值。

這裏是我的代碼：

Answer 1

替換該行

String curTime1 = String.format("%02d",minuteFinal1); 
b = a+" "+hourFinal1+":"+curTime1; 

有：

String curTime1 = String.format("%02d",minute1); 
b = a+" "+hour1+":"+curTime1;
