BlackBerry InputStream轉換爲字符串

Question

如何將InputStream轉換爲BlackBerry上的字符串？

Answer 1

我會將inputStream中的數據存儲在StringBuffer中。代碼如下所示：

byte[] buffer = new byte[1024]; 
StringBuffer sb = new StringBuffer(); 
int readIn = 0; 
while((readIn = inputStream.read(buffer)) > 0) 
{ 
    String temp = new String(buffer, 0, readIn); 
    sb.append(temp); 
} 
String result = sb.toString();

Jonathan的方法假定您的字節表示默認BlackBerry編碼（ISO-8859-1）中的字符串。然而大多數現代應用都是多語言的，所以支持的最好的編碼是UTF-8。要尊重一組編碼你可以使用水木清華這樣的：

/** 
* Constructs a String using the data read from the passed InputStream. 
* Data is read using a 1024-chars buffer. Each char is created using the passed 
* encoding from one or more bytes. 
* 
* <p>If passed encoding is null, then the default BlackBerry encoding (ISO-8859-1) is used.</p> 
* 
* BlackBerry platform supports the following character encodings: 
* <ul> 
* <li>"ISO-8859-1"</li> 
* <li>"UTF-8"</li> 
* <li>"UTF-16BE"</li> 
* <li>"UTF-16LE"</li> 
* <li>"US-ASCII"</li> 
* </ul> 
* 
* @param in - InputStream to read data from. 
* @param encoding - String representing the desired character encoding, can be null. 
* @return String created using the char data read from the passed InputStream. 
* @throws IOException if an I/O error occurs. 
* @throws UnsupportedEncodingException if encoding is not supported. 
*/ 
public static String getStringFromStream(InputStream in, String encoding) throws IOException { 
    InputStreamReader reader; 
    if (encoding == null) { 
     reader = new InputStreamReader(in); 
    } else { 
     reader = new InputStreamReader(in, encoding);    
    } 

    StringBuffer sb = new StringBuffer(); 

    final char[] buf = new char[1024]; 
    int len; 
    while ((len = reader.read(buf)) > 0) { 
     sb.append(buf, 0, len); 
    } 

    return sb.toString(); 
}

這個怎麼樣了最少的代碼：

String str = new String(IOUtilities.streamToBytes(is), "UTF-8");
