谢谢你

Handler speedHandler = new Handler();

    Runnable unitspeedtimer = new Runnable() {
             public void run() {    
               speedTextView=(TextView)findViewById(R.id.speedTextView);
               MaxspeedTextView=(TextView)findViewById(R.id.MaxspeedTextView);
               //1 m/s = 3.6 km/h
               float MySpeed = location.getSpeed() * 3.6;   
              float MaxSpeed = 75.00;


                Timer updateTimer = new Timer("velocityUpdate");
              updateTimer.scheduleAtFixedRate(new TimerTask() {
                  public void run() {
                    updateGUI();
                  }
                }, 0, 3000);
             }

最后你还需要一个};来关闭 Runnable。一致的缩进在这里真的很有帮助。
