Question

我想在我的代码中加上 60秒的延迟。我用了下面的代码，加了一些延迟;但它的行为并不像预期的那样。

new Handler().postDelayed(new Runnable() {
    @Override
    public void run() {
        //Calling my function after 15 seconds delay.
    }
}, 15000);

P.S。：我不想使用 Thread.sleep（），因为它会在正常的应用程序操作中造成障碍。

您可以尝试使用CountDownTimer。

// You can change millisInFuture and countDownInterval according to your need.
long millisInFuture = 60000;
long countDownInterval = 1000;

new CountDownTimer(millisInFuture, countDownInterval) {
     @Override
     public void onTick(long l) {
         // Method call according to countDownInterval.
         // For E.g we are taking 1000 so this method call every 1 second.
     }

     @Override
     public void onFinish() {
         // When 60 second completed call this method.
         // Do your logic here.
     }
}.start();

您想要做的事情就像这样。

long millisInFuture = 60000;
    long countDownInterval = 1000;
    int counter = 0;

    new CountDownTimer(millisInFuture, countDownInterval) {
        @Override
        public void onTick(long l) {
            // Method call according to countDownInterval.
            // For E.g we are taking 1000 so this method call every 1 second.
        }

        @Override
        public void onFinish() {
            // When 60 second completed call this method.
            // Do your logic here.
            counter++;
            if (counter == 1) {
                // Call your 1st function
            } else if (counter == 2) {
                // Call your 2nd function
            } else if (counter == 3) {
                // Call your 3rd function
            } else if (counter == 4) {
                // Call your 4th function
            } else if (counter == 5) {
                // Call your 5th function
            }

            if (counter < 5) {
                start();
            }
        }
    }.start();
