Java字节流乱码有关问题(2)

                            for(int i=0; i < size; i ++){
                                int tmpSize = size_btCat;
                                m_btCat[tmpSize + i] = buffer[i];
                            }
                            
                            String tmpStrSec = new String(m_btCat, 0, m_btCat.length);
                            Arrays.fill(m_btCat,(byte)0); 
                            postBroadcast(tmpStrSec);
                        }
                        else{
                          //if string is bigger than 32bytes, we should concat not only times
                            for(int i=0; i < size; i ++){                                
                                int tmpSize = size_btCat;
                                m_btCat[tmpSize + i] = buffer[i];
                            }
                            
                            //m_strCat = m_strCat.concat(str);
                        }
------解决方案--------------------
我觉得直接用字符读取不就行了吗？难道有只能用字节读取的需求要求？
