android無法轉換字串到整型

問題描述：

從一個XML檔案中擷取字串，內容大概就是262626這樣。現在需要將字串轉換到 MB (/1024)形式。但是不能轉換int或者長整型。我的測試代碼：

[java]
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()); 
    } 

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());
    }我還測試了：

[java]
nteger.valueOf(str);  

Integer.valueOf(str);
得到的錯誤：

解決方案：

報這個warning的不是你的轉換，而是你接下來的這句getString()
你改測試就簡單的好好測，看如下

[java]
try { 
            int s = Integer.parseInt(size); 
    　　　　System.out.println("Got num is:"+s);//正確  
            //Log.i("s", getString(s));  
        ..... 

try {
            int s = Integer.parseInt(size);
    　　　　System.out.println("Got num is:"+s);//正確
            //Log.i("s", getString(s));
        .....
關於getString()的用法解釋是:
Return a localized string from the application's package's default string table.
你可以在values下的strings.xml下定義一個

[java]
<string name="my_str">abc123456</string> 

<string name="my_str">abc123456</string>
然後這樣去得到它:

[java]
Log.i("s", getString(R.string.my_str));//s abc123456 

Log.i("s", getString(R.string.my_str));//s abc123456
