我怎样才能得到正确答案在正确答案的位置显示

Question

我正在创建一个工作正常的问答游戏，但遇到的问题是每当用户选择正确的答案，它显示它是错误的答案，同时这是正确的答案，事实证明正确的答案不在正确的位置。

这是我的代码到目前为止，任何想法如何我可以解决这个问题。

public class RiddleGuessActivity extends AppCompatActivity { 
     TextView riddleQuestionTextView; 
     Button btn1, btn2, btn3, btn4, btnContinue, btnOk; 

     ArrayList<String> riddles = new ArrayList<>(); 
     ArrayList<String> answers = new ArrayList<>(); 
     int locationOfCorrectAnswers = 0,incorrectAnswers = 0; 
     ArrayList<String> options = new ArrayList<>(); 
     LinearLayout gameOverLayout; 
     LinearLayout buttonLayout; 
     RelativeLayout resultLayout; 
     TextView timerTextView; 
     TextView answerTextView; 
     TextView levelTextView, scoreTextView; 
     TextView gameOverTextView; 
     int levelCounter = 1, scoreCounter, riddleCounter = 0; 

     public void chosenRiddle (View view) { 

      if (view.getTag().toString().equals(Integer.toString(locationOfCorrectAnswers))) { 

       //Toast.makeText(RiddleGuessActivity.this, "Correct", Toast.LENGTH_SHORT).show(); 
       levelCounter++; 
       scoreCounter+=60; 
       riddleCounter++; 
       levelTextView.setText(String.valueOf(levelCounter)); 
       scoreTextView.setText(String.valueOf(scoreCounter)); 

       result(); 

      }else { 

       Toast.makeText(RiddleGuessActivity.this, "Wrong, It was " + 
         answers.get(riddleCounter), Toast.LENGTH_SHORT).show(); 
       gameOver(); 
      } 
     } 

     public void generateRiddles() { 

      riddles.add("I kiss my mother before i die. What am i ?"); 
      riddles.add("It is greater than God and more evil than the devil. The poor have it, the rich need it and if you eat it you'll die. What am i ?"); 
      riddles.add("It walks on four legs in the morning, two legs at noon and three legs in the evening. What am i ?"); 
      riddles.add("I am the beginning of the end, and the end of time and space. I am essential to creation and i surround everyplace. What am i ?"); 
      riddles.add("What always runs but never walks, often murmurs, never talks, has a bed but never sleeps, has a mouth but never eats. What am i ?"); 
      riddles.add("At night they come without being fetched, By day they are lost without being stolen. What am i ?"); 
      riddles.add("The one who makes it, sells it. The one who buys it, never uses it. The one that uses it never knows that he's using it. What am i ?"); 
      riddles.add("The more you have of it, the less you see. What am i ?"); 
      riddles.add("I am always hungry, i must be fed, the finger i touch will soon turn red. What am i ?"); 
      riddles.add("If you break me, i do not stop working, if you touch me, i may snared, if you lose me, nothing will matter. What am i ?"); 

      answers.add("Matches"); 
      answers.add("Nothing"); 
      answers.add("Man"); 
      answers.add("Letter E"); 
      answers.add("River"); 
      answers.add("The Stars"); 
      answers.add("A Coffin"); 
      answers.add("Darkness"); 
      answers.add("Fire"); 
      answers.add("Heart"); 
      answers.add("The Moon"); 
      answers.add("Food"); 
      answers.add("Love"); 
      answers.add("Mouth"); 
      answers.add("Money"); 

      Random random = new Random(); 

      riddleQuestionTextView.setText(riddles.get(riddleCounter)); 

      locationOfCorrectAnswers = random.nextInt(4); 

      options.clear(); 

      for (int i = 0; i < 4; i++) { 

       if (i == locationOfCorrectAnswers && 
         !options.contains(answers.get(riddleCounter))) { 

        options.add(answers.get(riddleCounter)); 

       }else { 

        incorrectAnswers = random.nextInt(answers.size()); 

        while (incorrectAnswers == riddleCounter) { 

         incorrectAnswers = random.nextInt(answers.size()); 
        } 

        if(!options.contains(answers.get(incorrectAnswers))) 
         options.add(answers.get(incorrectAnswers)); 
        else --i; 

       } 

      } 

      btn1.setText(options.get(0)); 
      btn2.setText(options.get(1)); 
      btn3.setText(options.get(2)); 
      btn4.setText(options.get(3)); 
     } 

Answer 1

您是否缺少一个onCreate方法？

无论如何，我建议你添加correctAnswer后跟不正确的options。基本上，忘记随机数字和while循环。

然后Collections.shuffle()的清单。

然后扫描列表以找到正确答案的位置。
