標題: 將接收到的資料放入陣列卻會遺失
本帖最後由 kansas73 於 2013-10-7 21:14 編輯

從手機接收藍芽送出來的資料
然後將之一一放進陣列
按下按鈕後開始讀取
然後顯示在各自的textview
結果發生悲劇
data[0]的資料是64
data[1]的資料是02
data[2]=00
data[3]=2B
.
.
.
可是當一按下去textview1的確會短暫顯示出64
結果下一秒就會被覆寫成02
然後後面的陣列就會全部往前移
變成data[0]=02、data[1]=00、data[2]=2B...全部往前
之後我在按下讀取資料的按紐
textview1就會先顯示出64然後馬上會跳回顯示02
可是其他的陣列就會全部往前不變了data[1]就會變成data[2]的資料
data[2]就會變成data[3]的資料
求解謝謝拜託各位大大
已經研究了好幾天找不出問題

====CODE如下======
private class SppReceiver extends Thread{
   private InputStream input=null;

   public SppReceiver(InputStream in){
   input = in;
   Log.i(tag, "SppReceiver");
   }
   /* 接收SPP訊息...*/
   public void run(){
   byte[] data  = new byte[1024];
   int length;
   short tmp[] = new short [20];
   double vo;
   if (input == null){
   Log.d(tag, "InputStream null");
   return;
   }
   while (true){
   try{
   Thread.sleep(500);
   length=input.read(data);
   tmp[0]=(short) (0xff & data[0]);
   tmp[1]=(short) (0xff & data[1]);
   tmp[2]=(short) (0xff & data[2]);
   tmp[3]=(short) (0xff & data[3]);
   tmp[4]=(short) (0xff & data[4]);
   tmp[5]=(short) (0xff & data[5]);
   tmp[6]=(short) (0xff & data[6]);

   tmp[9]=(short) (0xff & data[9]);
   tmp[10]=(short) (0xff & data[10]);
   tmp[11]=(short) (0xff & data[11]);
   tmp[12]=(short) (0xff & data[12]);
   vo =0.01*( (tmp[7]*256) + tmp[8] );
   Log.i(tag, "SPP receiver");
   if (length>0){
   //Log.i(tag,"R: "+ new String(data,0,length, "ASCII")+"
");
   msg=Double.toString(vo);
   msg1=Integer.toString(tmp[0],0);
   msg2=Integer.toString(tmp[1]);
   msg3=Integer.toString(tmp[2]);
   msg4=Integer.toString(tmp[7]);
   msg5=Integer.toString(tmp[8]);
   msgetr=Integer.toHexString(data[0]);
   btHandler.sendEmptyMessage(0);//將所有要顯示的訊息都丟去btHandler
   }
   }catch (Exception e){//IOException e
   Log.e(tag, "SppReceiver_disconnect");
   disconnect();
   }
   }
   }
   }
   /*將訊息顯示再Textview中畫面*/
   Handler btHandler = new Handler(){

}
   };

code貼出來大家幫你查
都沒code也看不出個所以然吧
