是什麼導致我的應用程序在此程序中崩潰？ - Android Studio

Question

我寫了一個程序，其中生成隨機數並將其顯示在屏幕上，並將它們顯示在一起。用戶然後必須輸入兩個或更多數字的總和來得分點。在下面的代碼中都清楚了。我的問題是，當開始遊戲的按鈕按下時，我的應用程序崩潰/我以前沒有這個問題，雖然程序沒有完全完成，所以我不得不進一步開發它。在這種情況下，我遇到了應用程序崩潰的問題。我相信這與loadG2a和loadG2b隨機int變量有關，可能或者將它們作爲（numbers.getText（））集成到parseInt中，或者將它們一起放置在「數字」TextView中。它可能不是這些。無論哪種方式，我都試圖解決這個問題，但沒有找到解決辦法。這裏的代碼：

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); 

             } 

             if (score>=4 && score<=6){ 
              int loadG2a = generateG2.nextInt(899)+100; 
              int loadG2b = generateG2.nextInt(899)+100; 
              int loadG2c = 0; 
              int loadG2d = 0; 
              numbers.setText(loadG2a+loadG2b); 
             }

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

          return false; 
         }

       } 

我很感謝任何人願意幫我解決這個問題，並得到程序運行的方式。請隨意替換必要的任何代碼。提前謝謝了。

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+"");
