android 每行读取本地文件并转换为map对象

}
如果调用
public Map<Integer, String> filemaps;
filemaps = readmode.readTxtFile(); num = filemaps.size();//
mPdsn =filemaps.get(dex);//读取内容
定时读取方位
myTimerTask timerTask = new myTimerTask();Timer timer = new Timer(true);timer.schedule(timerTask, 0, 11000);//定时11每秒执行一次
private class myTimerTask extends TimerTask {   @Override   public void run() {      Log.i("task","这是第"+dex+"次循环");      if(dex>filemaps.size() )      {         return;      }
Message message2 = new Message();message2.what = 2;myHandlerLoop.sendMessage(message2);  /
 }
Handler myHandlerLoop = new Handler() {   // 接收到消息后处理   public void handleMessage(Message msg) {      switch (msg.what) {         case 1:            //UI操作            break;         case 2:            //UI操作            //dex = dex++;                      break;      }      super.handleMessage(msg);   }};
