Android Studio：ImageButton在點擊時未激活

Question

我正在開發此應用程序，並正在對其進行測試，但我不太清楚哪裏出了什麼問題。當我點擊或按住Deck Button時，絕對沒有任何反應。只有在logcat中顯示的是Touch Events。我認爲這可能是我的格式有問題，但由於這是我第一次使用Java（過去只使用了微處理器類的程序集），我不確定它會是什麼。

編輯：刪除了很多額外的代碼無關的每個建議

這裏的問題是MainActivity.java

public class MainActivity extends AppCompatActivity { 
    int i=0; 
    int VOA=0; 
    int VOB=0; 
    int [] c ={1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30}; 



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


// The Draw Control for the Deck. It will only draw if it is in it's 0 state 
     ImageButton Deck =(ImageButton)(findViewById(R.id.Deck)); 
     assert Deck != null; 
     Deck.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       if(VOA==0){ 
        VOA=c[i]; 
        i=i+1; 


       } else if (VOB==0){ 
        VOB=c[i]; 
        i=i+1; 

       } 

      } 
     }); 

// Uses Collections shuffle to shuffle c 
     Deck.setOnLongClickListener(new View.OnLongClickListener() { 
      @Override 
      public boolean onLongClick(View v) { 
       List c= new ArrayList(); 
       Collections.shuffle(c); 


       return false; 
      }}); 


//Discard for Objective A by setting it to 0 and thus updating it's case statement. 
     ImageButton ObjectiveA =(ImageButton)(findViewById(R.id.ObjectiveA)); 
     assert ObjectiveA != null; 
     ObjectiveA.setOnLongClickListener(new View.OnLongClickListener() { 
      @Override 
      public boolean onLongClick(View v) { 
       VOA=0; 
       return false; 
      } 
     }); 



//Discard for Objective B by setting it to 0 and thus updating it's case statement. 
     ImageButton ObjectiveB =(ImageButton) (findViewById(R.id.ObjectiveB)); 
     assert ObjectiveB != null; 
     ObjectiveB.setOnLongClickListener(new View.OnLongClickListener() { 
      @Override 
      public boolean onLongClick(View v) { 
       VOB=0; 
       return false; 

      } 
     }); 

     } 
    } 
} 

這裏是activity_main.xml中以及

<?xml version="1.0" encoding="utf-8"?>

</RelativeLayout>

如果您消耗longclickListener()

返回true 210
