Question

我在.net web服务中使用此代码将图像作为字节数组发送：

public byte[] getImage()
{
    byte[] img;
    ....
    return img;
}

如何使用ksoap2读取此字节数组并将其转换为位图？

你能用简单的代码解释一下。

更新：这个代码我在android中用来从web服务中读取数据：

        String SOAP_ACTION = WebServiceNameSpace + GetImage;
        String NAMESPACE = WebServiceNameSpace;
        String METHOD_NAME = GetImage;
        String URL = WS_URL;

        SoapObject request = new SoapObject(NAMESPACE, METHOD_NAME);
        SoapSerializationEnvelope Envelope = new SoapSerializationEnvelope(
                SoapEnvelope.VER11);
        Envelope.dotNet = true;
        Envelope.setOutputSoapObject(request);
        HttpTransportSE transport = new HttpTransportSE(URL);
        transport.call(SOAP_ACTION, Envelope);
        SoapPrimitive primetive = (SoapPrimitive) Envelope.getResponse();
        return primetive.toString();

Answer 1

考虑到您已成功使用Web服务并检索字节，您只需解码数据并从中检索Bitmap：

final SoapPrimitive primitive = (SoapPrimitive) Envelope.getResponse();
final String imgData = primitive.toString();
if (imgData != "") 
{
    byte[] imgBytes = Base64.decode(imgData, Base64.DEFAULT);         
    final Bitmap bitmap = BitmapFactory.decodeByteArray(imgBytes, 0, imgBytes.length);
    // TODO: set this bitmap into an ImageView or handle it as you wish
}

如果解码部分有问题，请参阅this answer and its links。
