称为递归onResume活动java.lang.StackOverflowError的方法：堆栈大小8MB

Question

我在datetimeformat中收到此异常，它运行多个ti

public String parseDateToddMMyyyy(String time) {
    String inputPattern = "yyyy-MM-dd";
    String outputPattern = "dd-MM-yyyy";
    SimpleDateFormat inputFormat = new SimpleDateFormat(inputPattern);
    SimpleDateFormat outputFormat = new SimpleDateFormat(outputPattern);

    Date date = null;
    String str = null;

    try {
        date = inputFormat.parse(time);
        str = outputFormat.format(date);
    } catch (ParseException e) {
        e.printStackTrace();
    }
    return str;
}

我在例外之下

我在这里叫它

public void orderingResult(JSONArray Result) {    
for (int i = 0; i < Result.length(); i++) {
try {
     JSONObject jobj = Result.getJSONObject(i);
     try{               jobj.put("ausTimeJobDate",parseDateToddMMyyyy(jobj.getString("Job_Date")));
     }catch(Exception ex){
           ex.printStackTrace(); 
     }
  }catch(Exception ex){
       ex.printStackTrace();
  }

}

我不明白为什么这个函数要多次调用

注意：此函数不是递归的

Answer 1

您调用该函数多少次？ 一次创建SimpleDateFormat对象，而不是每次都创建。
