正しい答えの場所に表示する正解を得るにはどうすればいいですか？

Question

私はうまく動作しているクイズゲームを作成していますが、ユーザーが正しい答えを選択するたびに、一方、それは正しい答えです、正しい答えが正しい場所にないことが判明しました。

私のこれまでのコードは、これを修正する方法はありますか？

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

あなたはonCreateメソッドがありませんか？

とにかく、correctAnswerに続けて、間違ったoptionsを追加することをおすすめします。基本的には、乱数とwhileループを忘れてしまいます。

次にCollections.shuffle()のリスト。

次に、正しい回答の場所をリストでスキャンします。
