稱為遞歸onResume活動java.lang.StackOverflowError的方法：堆棧大小8MB

Question

我在datetimeformat中收到此異常，它運行多個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

Fatal Exception: java.lang.StackOverflowError: stack size 8MB

我在這里叫它

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();
  }

}

我不明白為什么這個函數要多次調用

注意：此函數不是遞歸的

Answer 1

您調用該函數多少次？ 一次創建SimpleDateFormat對象，而不是每次都創建。
