どのように私は画像を比較することができます

Question

私は質問として画像を使用していて、ここで私は配列から画像を比較する方法がわからないという多項選択クイズアプリを開発しています。 onclickメソッドでは、配列に格納された正しい答えとクリックされた選択肢を比較していますが、それでも私はsetTagとgetTagの選択肢を使用しています。

しないでください。downvote質問してください。

ここに私のコードです。

public class counting extends AppCompatActivity { 
    ImageView choice_one, choice_two, choice_three, choice_four; 
    ImageView question; 
    MediaPlayer mp; 
    private Questions mQuestions = new Questions(); 
    private int mAnswer; 
    private int mQuestionsLength = mQuestions.mQuestions.length; 

    Random r; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_counting); 

     r = new Random(); 

     choice_one=(ImageView)findViewById(R.id.choice_1); 
     choice_two=(ImageView)findViewById(R.id.choice_2); 
     choice_three=(ImageView)findViewById(R.id.choice_3); 
     choice_four=(ImageView)findViewById(R.id.choice_4); 

     choice_one.setTag(1); 
     choice_two.setTag(2); 
     choice_three.setTag(3); 
     choice_four.setTag(4); 

     question=(ImageView)findViewById(R.id.question); 

     updateQuestions(r.nextInt(mQuestionsLength)); 

     choice_one.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if(getImageResource(choice_one) == mAnswer){ 
        mp=MediaPlayer.create(counting.this,R.raw.bird); 
        mp.start(); 
        updateQuestions(r.nextInt(mQuestionsLength)); 
       }else{ 
        mp=MediaPlayer.create(counting.this,R.raw.april); 
        mp.start(); 
       } 
      } 
     }); 

     choice_two.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if(getImageResource(choice_two) == mAnswer){ 
        mp=MediaPlayer.create(counting.this,R.raw.bird); 
        mp.start(); 
        updateQuestions(r.nextInt(mQuestionsLength)); 
       }else{ 
        mp=MediaPlayer.create(counting.this,R.raw.april); 
        mp.start(); 
       } 
      } 
     }); 

     choice_three.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if(getImageResource(choice_three) == mAnswer){ 
        mp=MediaPlayer.create(counting.this,R.raw.bird); 
        mp.start(); 
        updateQuestions(r.nextInt(mQuestionsLength)); 
       }else{ 
        mp=MediaPlayer.create(counting.this,R.raw.april); 
        mp.start(); 
       } 
      } 
     }); 

     choice_four.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if(getImageResource(choice_four) == mAnswer){ 
        mp=MediaPlayer.create(counting.this,R.raw.bird); 
        mp.start(); 
        updateQuestions(r.nextInt(mQuestionsLength)); 
       }else{ 
        mp=MediaPlayer.create(counting.this,R.raw.april); 
        mp.start(); 
       } 
      } 
     }); 
    } 

    private int getImageResource(ImageView iv){ 
     return (Integer)iv.getTag(); 
    } 

    private void updateQuestions(int num){ 
     question.setImageResource(mQuestions.getQuestion(num)); 
     choice_one.setImageResource(mQuestions.getChoice1(num)); 
     choice_two.setImageResource(mQuestions.getChoice2(num)); 
     choice_three.setImageResource(mQuestions.getChoice3(num)); 
     choice_four.setImageResource(mQuestions.getChoice4(num)); 

     mAnswer = mQuestions.getAnswer(num); 
    } 
}

、あなたが提供しているそのタグでリソースIdを比較している

getImageResource(choice_one) == mAnswer 

に間違った比較を行っている（1,2,3,4） 。これは間違っています。

あなたはこの方法でそれを行う可能性があります -

private void updateQuestions(int num){ 
     question.setImageResource(mQuestions.getQuestion(num)); 
     question. setTag(mQuestions.getQuestion(num)); 
     choice_one.setImageResource(mQuestions.getChoice1(num)); 
     choice_one.setTag(mQuestions.getChoice1(num)); 
     choice_two.setImageResource(mQuestions.getChoice2(num)); 
     choice_two.setTag(mQuestions.getChoice2(num)); 
     choice_three.setImageResource(mQuestions.getChoice3(num)); 
     choice_three.setTag(mQuestions.getChoice3(num)); 
     choice_four.setImageResource(mQuestions.getChoice4(num)); 
     choice_four.setTag(mQuestions.getChoice4(num)); 

     mAnswer = mQuestions.getAnswer(num); 
    } 

は、あなたが提供している（コードの下）タグを外し、

 choice_one.setTag(1); 
     choice_two.setTag(2); 
     choice_three.setTag(3); 
     choice_four.setTag(4);
