我用下面的代码：

​​

请参阅我已经发布below.The图像路径即将完美的logcat的，所以在milliseconds.But的时候，我试图在毫秒转换成日期格式，然后我总是得到：1970年1月17日

我也曾尝试另一种方法来转换日期米利斯，但最终得到相同的结果：

public static String convertDate(long dateInMilliseconds,String dateFormat) { 
     return DateFormat.format(dateFormat, dateInMilliseconds).toString(); 
    } 

Answer 1

你是从你的光标获得的数量是在Unix Time，其对自1月经过1970年对于要在毫秒值的生成日期秒数的格式。简单的解决方案是将你的结果乘以1000，你很好。

Answer 2

取而代之的是

  Date d = new Date(dateofimage); 
     java.text.DateFormat formatter = new SimpleDateFormat("MMMM dd, yyyy h:mmaa"); 
     String dateString = formatter.format(d); 

试试这个

 Timestamp timeStamp = new Timestamp(dateofimage * 1000); 
     String dateString = timeStamp.toLocaleString();
