case MESSAGE_STATE_CHANGE:
                if(D) Log.i(TAG, "MESSAGE_STATE_CHANGE: " + msg.arg1);
                switch (msg.arg1) {
                case BluetoothChatService.STATE_CONNECTED:
                    setStatus(getString(R.string.title_connected_to, mConnectedDeviceName));
                    mConversationArrayAdapter.clear();
                    break;
                case BluetoothChatService.STATE_CONNECTING:
                    setStatus(R.string.title_connecting);
                    break;
                case BluetoothChatService.STATE_LISTEN:
                case BluetoothChatService.STATE_NONE:
                    setStatus(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:
                byte[] readBuf = (byte[]) msg.obj;
                Log.d("hoy", "readBuf===="+ readBuf);
                // construct a string from the valid bytes in the buffer
                String readMessage = new String(readBuf, 0, msg.arg1);
//                mConversationArrayAdapter.add(mConnectedDeviceName+":  " + readMessage);

                reciveData = readMessage;
                Log.d("hoy", "ReciveData==="+reciveData);}

我知道您正在尝试从ELM327蓝牙适配器检索数据。有一个库可以帮助您管理Android设备和OBD-II加密狗之间的通信。我用它,它帮助了我很多。 您可以在此处找到它:https://github.com/pires/android-obd-reader
