java - 造成程序执行延迟

Question

我想在我的代码中创建一个延迟，其中一部分应在 5 秒后执行，另一部分应在 10 秒后执行。我已经尝试过 TRY CAtcH 线程，但不知道问题出在哪里..这是我的代码，请看一下..先谢谢了....

 // This portion to be executed after 5 seconds 

              val1 = Integer.parseInt(String.valueOf(unit.getText()));
              val2 = Integer.parseInt(String.valueOf(unit2.getText()));
              result = val1 + val2;

              val = Integer.toString(result);
             int len = val.length();

              if (len == 1) {

                  num1 = Integer.parseInt(String.valueOf(val.toString().charAt(len - 1)));

                  unitanswer1.setText(Integer.toString(num1));
                  unitanswer2.setText(Integer.toString(0));
                  unitanswer2.setVisibility(View.INVISIBLE);

              } else {
                  num1 = Integer.parseInt(String.valueOf(val.toString().charAt(len - 1)));
                  unitanswer1.setText(Integer.toString(num1));

                  num2 = Integer.parseInt(String.valueOf(val.toString().charAt(len - 2)));
                  unitanswer2.setText(Integer.toString(num2));
              }

//这部分10秒后执行

             val1 = Integer.parseInt(String.valueOf(tens.getText()));
             val2 = Integer.parseInt(String.valueOf(ten2.getText()));
             val3=Integer.parseInt(String.valueOf(unitanswer2.getText()));

             result = val1 + val2 + val3;

            val = Integer.toString(result);
             len = val.length();

            if (len == 1) {

                num1 = Integer.parseInt(String.valueOf(val.toString().charAt(len - 1)));

               tenanswer1.setText(Integer.toString(num1));
                tenanswer2.setText(Integer.toString(0));
                tenanswer2.setVisibility(View.INVISIBLE);

            }
            else {
                num1 = Integer.parseInt(String.valueOf(val.toString().charAt(len - 1)));
               tenanswer1.setText(Integer.toString(num1));

                num2 = Integer.parseInt(String.valueOf(val.toString().charAt(len - 2)));
                tenanswer2.setText(Integer.toString(num2));

                //Animation's work to be done here.....
                //remaining possibilites of addition....
            }
            }

试试这个:

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            // This portion to be executed after 5 seconds 
             ...
        }
    },5*1000);  

还有这个:

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            //This portion to be executed after 10 seconds
            ... 
        }
    },10*1000);

希望对您有帮助。
