Android 将字符串转换为日期

Question

我正在从 JSON 响应中获取字符串格式的日期，但现在我想将该起始日期转换为日期格式。我如何将此 strActiondate: = 9/28/2015 6:52:41 PM 转换为 date ，以便我可以插入到 Sq-lite 数据库中。

我试过这种方法

strActiondate = jobjVessels.getString("actionDate");                

Log.e("strActiondate ", " = " + strActiondate);
try{
    DateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
    Date netDate = (new Date(Long.parseLong(strActiondate)));
    Log.e("netDate "," = "+netDate);

}
catch(Exception ex){
    ex.printStackTrace();
}

我想要相同格式的日期 = 9/28/2015 6:52:41 PM

Answer 1

此日期格式:MM/dd/yyyy，对此日期无效:9/28/2015 6:52:41 PM.

你需要一个好的SimpleDateFormat匹配这个字符串:

a   Am/pm marker        Text    PM
H   Hour in day (0-23)  Number  0
m   Minute in hour      Number  30
s   Second in minute    Number  55

所以这样:

String strActiondate = "9/28/2015 6:52:41 PM"; 
DateFormat sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a");
Date netDate = sdf.parse(strActiondate);
System.out.println(netDate);

将输出:

Mon Sep 28 06:52:41 CEST 2015

在您的代码中:

try{
    DateFormat sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss a");
    Date netDate = sdf.parse(strActiondate);       
    Log.d("netDate "," = "+netDate);  // log.e is an error... so better d or i
}
