Answer 1

1. 使用国名

例如:

import android.os.CountDownTimer;   

MyCount timerCount;
public class TestCountdown extends Activity {

  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    timerCount = new MyCount(3 * 1000, 1000);
    timerCount.start();
  }

  public class MyCount extends CountDownTimer {
      public MyCount(long millisInFuture, long countDownInterval) {
        super(millisInFuture, countDownInterval);
      }

      @Override
      public void onFinish() {
        //some script here
      }

      @Override
      public void onTick(long millisUntilFinished) {
        //some script here 
      }   
    } 
}

Answer 3

我不想就此写一下法典,但这不应是困难的。仅仅用透镜显示价值3(用文字表述)时,先听说(100人假定你想要在1个秘密之后改变)就减少了,重复了。

实例

for i=0 to 3
print the number 
thread.sleep(100)
