爲什麼我不能將字符串轉換爲整數

我知道它是一個簡單的主題，但我總是得到錯誤..我從xml文件中獲取數據包含的字符串，如262626我試圖將此字符串轉換爲MB（/ 1024）窗體。但它沒有轉換爲int或long有人能幫助我嗎？爲什麼我不能將字符串轉換爲整數

這裏是我的測試

String size = parser.getValue(e, parser.KEY_FileSizeInByte); 
Log.i("menuItems",size); 

    try { 
     int s = Integer.parseInt(size); 
     Log.i("s", getString(s)); 
    } 
    catch (Exception e1) { 
     Log.i("error", e1.getMessage()); 
    }

我還測試

Integer.valueOf(str);

這裏是我收到的錯誤：

首先，你目前正在使用'！='測試字符串相等。不要這樣做。另外，不要只記錄異常的*消息* - 記錄整個異常。 –

感謝您的幫助..我添加了這個檢查如果字符串是空的不會得到它的轉換錯誤（首先它是大小！= null我改變了大小！=「」也許問題修復） – Majid

這是你的日誌這是錯誤的。在這裏：

Log.i("s", getString(s));

這是試圖讓資源與給定的標識符。你只想：

Log.i("s", String.valueOf(s));
