Java/Android-将InputStream转换为字符串

Question

我正在通过蓝牙读取来自设备的持续数据流。我想知道如何将这些数据转换为字符串并将其打印出来？缓冲区将包含一个 ASCII 字符串，但当我运行它时，它会打印出整数，我希望能够看到该字符串。

 while (true) {
                try {
                    //read the data from socket stream
                    if(mmInStream != null) {
                       int input = mmInStream.read(buffer);

                       System.out.println(input);
                    }
                    // Send the obtained bytes to the UI Activity
                } catch (IOException e) {
                    //an exception here marks connection loss
                    //send message to UI Activity
                    break;
                }
            }

你可以试试这个。

public String isToString(InputStream is) {
        final int bufferSize = 1024;
        final char[] buffer = new char[bufferSize];
        final StringBuilder out = new StringBuilder();
        Reader in = new InputStreamReader(inputStream, "UTF-8");
        for (; ; ) {
            int rsz = in.read(buffer, 0, buffer.length);
            if (rsz < 0)
                break;
            out.append(buffer, 0, rsz);
        }
        return out.toString();
    }
