蓝牙模块每隔0.5秒发送一帧图像数据过来，手机接收后保存为jpg图片，现在只能将进入线程后接收到的第一次数据完整保存为jpg图片，之后每一次的数据都是不全的，这是为什么？接收数据的部分程序如下,我是想有数据传过来就接收处理的，不过感觉效果不好
//存储文件并显示的线程
private class saveimageThread extends Thread {
public saveimageThread(BluetoothSocket btSocket) {
InputStream tmpIn =null;
inStream=null;
try {
tmpIn=btSocket.getInputStream();
} catch (IOException e) {
Log.e(TAG,"temp scoket not created",e);
}
inStream=tmpIn;
}
@Override
public void run() {
int picname=1;
Log.i("saveimage","start");
//保存图片
try{
byte[] buffer=new byte[50000];
//dri为保存路径，SD卡中的carImage文件夹
//从蓝牙获取输入流
while (inStream!=null)
{
Log.e("","InputStream");
int l = -1;
try{
while((l = inStream.read(buffer)) != -1)
//l = inStream.read(buffer);
{
ByteArrayOutputStream outStream=new ByteArrayOutputStream();
outStream.write(buffer,0,buffer.length);
//inStream.close();
byte[] data = outStream.toByteArray();
Log.e("","data is ready!");
//后面都是对data数组进行处理m
while(data.length>0){
略
}
//break;
}
}catch (Exception e){
e.printStackTrace();}
break;
}
} catch (Exception e){
e.printStackTrace();
System.err.println("Can't start");
}
try {
sleep(10);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
