Java 数到0到100

倒计时0到100安卓 我是android的初学者，你们能帮我吗。 结果必须是倒计时结束。 例如，结果值为75。倒计时将从0开始到75结束

 mCalculate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showResult();
            new CountDownTimer(30000, 100){
               public void onTick(long millisUntilFinished){
                  waveLoadingView.setProgressValue(counter);
                  waveLoadingView.setCenterTitle(String.format("%d%%",result)); //result is the value from randomize 60 to 80 .

                    result++;
                }
                public  void onFinish(){
                }
            }.start();

        }
    });

试试下面的代码

 mCalculate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showResult();
            new CountDownTimer(result*1000, 1000){
               public void onTick(long millisUntilFinished){
                  waveLoadingView.setProgressValue(counter);
                  waveLoadingView.setCenterTitle(String.format("%d%%",newResult)); //newResult is temp value initialize with 0

                    newResult++; 
                }
                public  void onFinish(){
                }
            }.start();

        }
    });

在实例化用例时，您只需要使用匹配的参数，请查看CountDownTimer构造函数方法。当您想要创建一个从0到100的倒计时，并且只需1秒的步骤时，您可以这样构造代码：

final long ONE_SECOND = 1000;
final long ONE_HUNDRED_SECOND = 100 * ONE_SECOND;

new CountDownTimer(ONE_HUNDRED_SECOND, ONE_SECOND){
   public void onTick(long millisUntilFinished) {
      int second = millisUntilFinished / ONE_SECOND;

      int counter = second - 1;

      // do something with the counter value

    }
    public  void onFinish() {
      // do something when we finished the count down.
    }
}.start();

对不起，我更改了上面的问题，结果必须是倒计时结束。例如，结果值为75。倒计时将开始到0结束到75。倒计时将开始到75。倒计时的时间间隔为1秒。结果是整数。它正在工作，但即使我更改倒计时间隔，倒计时也会变慢。倒计时间隔为1秒。现在可以了。我更改了新的倒计时（结果*50，500）

// result varible define as a public
    long result = 80;
    mCalculate.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            new CountDownTimer(result * 1000, 100) {
                public void onTick(long millisUntilFinished) {
                    // its start with 1 if you want start with 0 then replace with below code
                    //int sec = (int) (result - (millisUntilFinished / 1000)-1);
                    int sec = (int) (result - (millisUntilFinished / 1000));
                    waveLoadingView.setProgressValue(sec);
                    waveLoadingView.setCenterTitle(String.valueOf(result)); //result is the value from randomize 60 to 80 .

                }

                public void onFinish() {
                }
            }.start();

        }
    });
