我正在通过套接字接收jpg图像,它作为ByteBuffer发送,我正在做的是:
ByteBuffer receivedData ;
// Image bytes
byte[] imageBytes = new byte[0];
// fill in received data buffer with data
receivedData= DecodeData.mReceivingBuffer;
// Convert ByteByffer into bytes
imageBytes = receivedData.array();
//////////////
// Show image
//////////////
final Bitmap bitmap = BitmapFactory.decodeByteArray(imageBytes,0,imageBytes.length);
showImage(bitmap1);
但是正在发生的事情是它无法解码imageBytes并且位图为null。
我也得到了imagebytes作为:imageBytes:{-1,-40,-1,-32,0,16,74,70,73,70,0,1,1,1,0,96,0,0,0 ,0,-1,-37,0,40,28,30,35,+10,478更多}
有什么问题吗?是解码问题吗?或从ByteBuffer转换为Byte数组?
在此先感谢您的帮助。
ByteBuffer buf = DecodeData.mReceivingBuffer;
byte[] imageBytes= new byte[buf.remaining()];
buf.get(imageBytes);
final Bitmap bmp=BitmapFactory.decodeByteArray(imageBytes,0,imageBytes.length);
showImage(bmp);
或者
// Create a byte array
byte[] bytes = new byte[10];
// Wrap a byte array into a buffer
ByteBuffer buf = ByteBuffer.wrap(bytes);
// Retrieve bytes between the position and limit
// (see Putting Bytes into a ByteBuffer)
bytes = new byte[buf.remaining()];
// transfer bytes from this buffer into the given destination array
buf.get(bytes, 0, bytes.length);
// Retrieve all bytes in the buffer
buf.clear();
bytes = new byte[buf.capacity()];
// transfer bytes from this buffer into the given destination array
buf.get(bytes, 0, bytes.length);
最终位图bmp = BitmapFactory.decodeByteArray(bytes,0,bytes.length); showImage(bmp);
使用以上任何一个将BYTEBUFFER转换为BYTE ARRAY并将其转换为位图并将其设置为IMAGEVIEW。
希望这会帮助你。
