Question

您好我试图延迟使用图像视图，让人觉得它们是逐个被取出的。我试过了

但他们要么只延迟一次，要么两个图像视图同时改变，要么根本不延迟。为了参考，我尝试做类似

的事情

 private void delaycard(final int Card) {

        newcard(Card); //Delay this before it is called
    }

此时愿意尝试/重试

Answer 1

离开我的头顶，尝试这样的事情：

                    Handler h = new Handler();
                    //for the number of images we have
                    for (int i = 0; i < numImages; i++) {

                        //we create a runnable for that action
                        Runnable r = new Runnable() {
                            @Override
                            public void run() {
                                newCard(card);
                            }
                        };

                        //this is the amount of time to delay it by
                        delay = delay + 500;
                        //effectively, we're creating a series of runnables at the same time
                        //but they activate one after the other in .5s intervals
                        h.postDelayed(r, delay);
                    }

Answer 2

把它放在你的方法

中

     Handler handler = new Handler();
     handler.postDelayed(new Runnable() {
      @Override
       public void run() {
           newCard(Card);
       }
     }, 100);
