如何在android中将图像转换为字节，并将该字节传递给Web服务

How to convert image into byte in android and that byte pass to web services

推荐答案

我假设你的意思是字节数组而不是字节，因为将图像转换为字节没有多大意义。

Hi,

I assume you mean a byte array and not a byte, because converting an image to a byte does not make much sense.

Have a look here:

Dhruv Gairola [ ^ ]写道：

试试这个：

Try this:

// convert from bitmap to byte array
public byte[] getBytesFromBitmap(Bitmap bitmap) {
    ByteArrayOutputStream stream = new ByteArrayOutputStream();
    bitmap.compress(CompressFormat.JPEG, 70, stream);
    return stream.toByteArray();
}

ProgramFOX已经为您提供了一个很好的解决方案。我想扩展它。请参阅上面这两个链接：

将图像转换为字节数组 [ ^ ]

将图像转换为ByteArray [ ^ ]

ProgramFOX already gave you a good solution. I want to extend that. See these 2 links with the above one:
Convert image to byte array[^]
