是什么导致我的应用程序在此程序中崩溃？ - Android Studio

Question

我写了一个程序，其中生成随机数并将其显示在屏幕上，并将它们显示在一起。用户然后必须输入两个或更多数字的总和来得分点。在下面的代码中都清楚了。我的问题是，当开始游戏的按钮按下时，我的应用程序崩溃/我以前没有这个问题，虽然程序没有完全完成，所以我不得不进一步开发它。在这种情况下，我遇到了应用程序崩溃的问题。我相信这与loadG2a和loadG2b随机int变量有关，可能或者将它们作为（numbers.getText（））集成到parseInt中，或者将它们一起放置在“数字”TextView中。它可能不是这些。无论哪种方式，我都试图解决这个问题，但没有找到解决办法。这里的代码：

final Button loseStarter2; 

     loseStarter2 = (Button) findViewById(R.id.Starter2); 
     loseStarter2.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       loseStarter2.setVisibility(View.GONE); 
       infoG2.setVisibility(View.GONE); 

       final Random generateG2 = new Random(); 
       final int loadG2a = generateG2.nextInt(89)+10; 
       final int loadG2b = generateG2.nextInt(89)+10; 
       final int loadG2c = 0; 
       final int loadG2d = 0; 
       final TextView numbers = (TextView) findViewById(R.id.numbers); 
       numbers.setText(loadG2a+loadG2b); 
       final EditText input2 = (EditText) findViewById(R.id.input2); 
       if (true) { 
        input2.setOnKeyListener(new View.OnKeyListener() { 
         @Override 
         public boolean onKey(View v, int keyCode, KeyEvent event) { 
          if (event.getAction() == KeyEvent.ACTION_DOWN) { 
           switch (keyCode) { 
            case KeyEvent.KEYCODE_ENTER: 
             Editable answer2 = input2.getText(); 
             int finalAnswer2 = Integer.parseInt(String.valueOf(answer2)); 
             int finalLoadG2 = Integer.parseInt(String.valueOf(numbers.getText())); 
             input2.getText().clear(); 

             if (finalAnswer2 == finalLoadG2) { 
              score++; 
             } 


             if (score>=0 && score<=3){ 
              int loadG2a = generateG2.nextInt(89)+10; 
              int loadG2b = generateG2.nextInt(89)+10; 
              int loadG2c = 0; 
              int loadG2d = 0; 
              numbers.setText(loadG2a+loadG2b); 

             }

              int loadG2a = generateG2.nextInt(899)+100; 
              int loadG2b = generateG2.nextInt(899)+100; 
              int loadG2c = 0; 
              int loadG2d = 0;

              int loadG2b = generateG2.nextInt(8999)+1000; 
              int loadG2c = generateG2.nextInt(8999)+1000; 
              int loadG2d = 0; 
              numbers.setText(loadG2a+loadG2b+loadG2c); 
             }

          return false;

我很感谢任何人愿意帮我解决这个问题，并得到程序运行的方式。请随意替换必要的任何代码。提前谢谢了。

Answer 1

// here is int's (all other lines with int's must be also corrected) 
numbers.setText(loadG2a+loadG2b+loadG2c+loadG2d); 

// but must be String =) 
numbers.setText(loadG2a+loadG2b+loadG2c+loadG2d+"");
