我会将inputStream中的数据存储在StringBuffer中。代码如下所示:
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的方法假定您的字节表示默认BlackBerry编码(ISO-8859-1)中的字符串。然而大多数现代应用都是多语言的,所以支持的最好的编码是UTF-8。要尊重一组编码你可以使用水木清华这样的:
/**
* 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();
}

这个怎么样了最少的代码:
String str = new String(IOUtilities.streamToBytes(is), "UTF-8");
