java - 如何延迟多个 if 条件语句？

Question

有没有办法可以在运行另一个 if 条件之前将 if 语句延迟 1 秒？我尝试为每个语句使用可运行的处理程序，但它使应用程序崩溃，我还使用了 Thread.sleep(1000);但它只是卡住了用户界面。我该如何解决这个问题？

这就是我第一次使用处理程序的方式

final Handler Internet_handler = new Handler();
       final Runnable internet = new Runnable() {
           public void run() {if (EseCards_Slot1.isShown()) {
   EseCards_Slot1.performClick();
   bot_count++;
   Stop_Two_InstantPLay(); // stops 2 cards from playing i.e pick 2 and ride on
   botThinkdelay();// delays the if statement
}
           }
       };
       Internet_handler.postDelayed(internet, 1700);

if (EseCards_Slot1.isShown()) {
   EseCards_Slot1.performClick();
   bot_count++;
   Stop_Two_InstantPLay(); // stops 2 cards from playing i.e pick 2 and ride on
   botThinkdelay();// delays the if statement
}
if (EseCards_Slot2.isShown()) {
   EseCards_Slot2.performClick();
   bot_count++;
   Stop_Two_InstantPLay();
   botThinkdelay();
}
if (EseCards_Slot3.isShown()) {
   EseCards_Slot3.performClick();
   bot_count++;
   Stop_Two_InstantPLay();
   botThinkdelay();
}
if (EseCards_Slot4.isShown()) {
   EseCards_Slot4.performClick();
   bot_count++;
   Stop_Two_InstantPLay();
   botThinkdelay();
}
if (EseCards_Slot5.isShown()) {
   EseCards_Slot5.performClick();
   bot_count++;
   Stop_Two_InstantPLay();
   botThinkdelay();
}
if ((bot_count>0)&&(Ese_Turn_toPlay==true)) {
   Market.performClick();
   bot_count=0;
   botThinkdelay();
}

我认为，您可以使用 Handler (请参阅 How to set delay in android? 或 How to use delay functions in Android Studio? )。代码变得丑陋，但我只知道 Java 中 UI 线程的几个解决方案(CountDownTimer)。

import android.os.Handler;

final Handler handler = new Handler();

if (EseCards_Slot1.isShown()) {
   EseCards_Slot1.performClick();
   bot_count++;
   Stop_Two_InstantPLay(); // stops 2 cards from playing i.e pick 2 and ride on
   handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            if (EseCards_Slot2.isShown()) {
               EseCards_Slot2.performClick();
               bot_count++;
               Stop_Two_InstantPLay();
               // Here comes the next Handler.
               // It would be better to divide if statements into methods
               // and run them inside each new handler.postDelayed.
            }
        }
    }, 1000);

}

关闭屏幕后，您应该删除所有处理程序。
