我从蓝牙发送90000字节数据。我在接收端获得了1024字节的块。我需要在单个数组中收集它们并生成一个字节数组。不能这样做..
这是代码：
private final Handler mHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
System.out.println("***************handleMessage***************"+msg.obj);
switch (msg.what) {
case MESSAGE_STATE_CHANGE:
if(D) Log.i(TAG, "MESSAGE_STATE_CHANGE: " + msg.arg1);
switch (msg.arg1) {
case BluetoothChatService.STATE_CONNECTED:
mTitle.setText(R.string.title_connected_to);
mTitle.append(mConnectedDeviceName);
mConversationArrayAdapter.clear();
break;
case BluetoothChatService.STATE_CONNECTING:
mTitle.setText(R.string.title_connecting);
break;
case BluetoothChatService.STATE_LISTEN:
case BluetoothChatService.STATE_NONE:
mTitle.setText(R.string.title_not_connected);
break;
}
break;
case MESSAGE_WRITE:
byte[] writeBuf = (byte[]) msg.obj;
// construct a string from the buffer
String writeMessage = new String(writeBuf);
mConversationArrayAdapter.add("Me: " + writeMessage);
break;
case MESSAGE_READ:
System.out.println("***************msg.obj***************"+msg.obj);
byte[] readBuf = (byte[]) msg.obj;
System.out.println("***************readBuf***************"+readBuf.length);
Bitmap bmp=BitmapFactory.decodeByteArray(readBuf,0,readBuf.length);
System.out.println("***************bmp***************"+bmp);
//convert it back to an image
ByteArrayInputStream imageStream = new ByteArrayInputStream(readBuf);
Bitmap theImage = BitmapFactory.decodeStream(imageStream);
System.out.println("***************theImage***************"+theImage);
try
{
String filepath=Environment.getExternalStorageDirectory().getAbsolutePath();
File file = new File(filepath, "barcode.PNG");
FileOutputStream fos = new FileOutputStream(file);
BufferedOutputStream bos = new BufferedOutputStream(fos);
theImage.compress(CompressFormat.JPEG, 100, fos);
bos.flush();
bos.close();
}
catch(Exception e)
{
System.out.println("***************Read***************"+e);
}
案件MESSAGE_READ：一次又一次地打电话。我通过蓝牙发送图像。在发送方并在接收方获得1024字节的块..
任何帮助都将不胜感激。
