时间戳记到字符串日期 [英] Timestamp to string date

问题描述

我不知道如何将时间戳转换为日期。
我有：

I don't know how to transform timestamp to date. I have:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    TextView czas = (TextView)findViewById(R.id.textView1);
    String S = "1350574775";
    czas.setText(getDate(S));        
}



private String getDate(String timeStampStr){
   try{
       DateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
       Date netDate = (new Date(Long.parseLong(timeStampStr)));
       return sdf.format(netDate);
   } catch (Exception ignored) {
    return "xx";
   }
} 

答案是：1970年1月16日，但是

And answer is: 01/16/1970, but it is wrong.

推荐答案

如果坚持使用 1350574775格式（以秒为单位），请尝试以下操作：

try this if you're sticking with "1350574775" format which is in seconds:

private void onCreate(Bundle bundle){
    ....
    String S = "1350574775";

    //convert unix epoch timestamp (seconds) to milliseconds
    long timestamp = Long.parseLong(s) * 1000L; 
    czas.setText(getDate(timestamp ));  
}



private String getDate(long timeStamp){

    try{
        SimpleDateFormat sdf = new SimpleDateFormat("MM/dd/yyyy");
        Date netDate = (new Date(timeStamp));
        return sdf.format(netDate);
    }
    catch(Exception ex){
        return "xx";
    }
}
