我想让sphero向前移动一定量的厘米,但到目前为止我还没有设法让任何东西正常工作这是我现在的代码:

EditText distanceText = (EditText) findViewById(R.id.distanceText);
int inputMSec = Integer.parseInt(distanceText.getText().toString());
int time = (inputMSec - inputMSec/2);

    // The ball is given the RollCommand at half speed.
    RollCommand.sendCommand(mRobot, heading,0.5f);

    // A handler is created to delay the Stop command.
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable(){

        @Override
        public void run() {
            // Makes the ball stop
            RollCommand.sendStop(mRobot);
        }
        // The variable 'time' defines how long the ball rolls until it is told to stop.
    }, time);

有没有其他命令我可以发送到球而不是RollCommand？或者任何人都可以从EditText中找到对输入做什么,以便距离变得正确？
