java - 如何为我的 Android 锻炼应用程序做组训练？

Question

首先感谢您阅读本文。受 Yaga 应用程序教程的启发，我为我的团队制作了一款锻炼应用程序。我的问题是在 Yaga 应用程序中你没有很多组，只有一组，我想添加组。我试图制作一个 for(int i = 0; i < 50; i++)在我的表演练习中，但它不起作用，我希望重复练习和其余部分，而不仅仅是练习。这是我的代码，

我的代码带有 for :

        if(ex_id < list.size())  //list size y'a ts les exos
        {
            for (int i = 0; i < 3; i++) {

                ex_image.setVisibility(View.VISIBLE);
                btnStart.setVisibility(View.VISIBLE);
                layoutGetReady.setVisibility(View.INVISIBLE);
                detail_text.setVisibility(View.VISIBLE);


                //Set Data youno

                ex_image.setImageResource(list.get(ex_id).getImage_id());
                ex_name.setText(list.get(ex_id).getName());
                detail_text.setText(list.get(ex_id).getDetail());

                showRestTime();
            }

        }
        else
            showFinished();

    }

非常感谢，史蒂芬

我阅读了您的要求，根据您的要求，您想逐一显示每组并重复它们。

您可以做的是为您的每组创建一个CountDownTimer设置时间段，然后在完成一组后，移至下一组，当您的setsList到达最后一组时重置或重复计时器。

示例代码

  int counter=-1;

    CountDownTimer timer=null;
    ArrayList<Foo> setsArrayList=null;


    // foo is generic class(add your model for sets) , and setFoo is object that contains single set details. 
    void startTimer(Foo setFoo) {

      if(null!=timer){
          timer.cancel();
       }



    timer=new CountDownTimer(totalTime, setFoo.singleSetTime) {

         public void onTick(long millisUntilFinished) {
            counter++;

            updateUI(setsArrayList.get[counter])

         }

         public void onFinish() {
            //"done!" or repeat all sets if you want to
            counter=0;
         updateUI(setsArrayList.get[counter])
         }
      }.start();


    }
