我有二进制流，我希望它以字节为单位进行转换。之后我想将它下载到 SD 卡中。
我的网络服务:

我正在尝试的是
SoapObject DocumentRequest = new SoapObject(NAMESPACE, GET_DOCUMENT_METHOD);
DocumentRequest.addProperty("DocumentID", ID);
Log.i("DocumentID", ID);
SoapSerializationEnvelope Envelope = new SoapSerializationEnvelope(SoapEnvelope.VER11);
Envelope.dotNet = true;
Envelope.setOutputSoapObject(DocumentRequest);
HttpTransportSE androidHttpTransport = new HttpTransportSE(URL);
androidHttpTransport.debug = true;
androidHttpTransport.call(SOAP_ACTION_GETDOCUMENT, Envelope);
SoapPrimitive DocumentResponse = (SoapPrimitive)Envelope.getResponse();
Log.i("DocumentResponse", DocumentResponse.toString());
String DocAsString = DocumentResponse.toString();
byte[] decodedString = DocAsString.getBytes();
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
ImageView DisplayDoc= (ImageView)findViewById(R.id.displayimage);
DisplayDoc.setImageBitmap(decodedByte);
}
我正在获取二进制流，因为字符串是正确的，或者我需要使用 base64binary。如果是这样，请告诉我下载 image/.pdf/word 文档的正确方法。我已经完成了差异搜索，但没有用。谢谢
编辑:
SoapPrimitive DocumentResponse = (SoapPrimitive)Envelope.getResponse();
Log.i("DocumentResponse", DocumentResponse.toString());
String DocAsString = DocumentResponse.toString();
byte[] decodedString = Base64.decode(DocAsString, Base64.DEFAULT);
/*Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);

最佳答案
try {
ht.call(SOAP_ACTION, envelope);
final SoapPrimitive response = (SoapPrimitive) envelope.getResponse();
String str =DocumentResponse.toString();
byte[] decodedString = Base64.decode(str, Base64.DEFAULT);
File direct = new File(Environment.getExternalStorageDirectory() + "/Foldername");
if(!direct.exists())
{
direct.mkdir();
}
File photo=new File(Environment.getExternalStorageDirectory() + "/Foldername",Filename);
if (photo.exists())
{
photo.delete();
}
try {
FileOutputStream fos=new FileOutputStream(photo.getPath());
fos.write(decodedString);
fos.close();
ContentValues values= new ContentValues();
}
catch (java.io.IOException e)
{
Log.e("PictureDemo", "Exception in photoCallback", e);
}
}
catch (Exception e) {
e.printStackTrace();
}
将您的字符串转换为 Base64 解码。
例子:byte[] decodedString = Base64.decode(str, Base64.DEFAULT);
使用该字节将文件保存在 SDCard 中。
例子:fos.write(decodedString);
