應用被強制關閉按鈕時按下

Question

我是讓按鈕組偵聽這樣的，但是當按鈕點擊應用程序被強制關閉，我不知道什麼是錯我的代碼，請檢查了這一點

這是我的應用程序的項目

公共類菜單的全部代碼擴展活動{

    button5.setOnClickListener(listener2);

         // TODO Auto-generated method stub 
          ((View) listener2).startAnimation(animFadeout2); 
        } 
       }); 


      animFadeout2.setAnimationListener(new AnimationListener() { 

       @Override 
       public void onAnimationStart(Animation animation) { 
        // TODO Auto-generated method stub 
       } 

       @Override 
       public void onAnimationRepeat(Animation animation) { 
        // TODO Auto-generated method stub 
       } 

       @Override 
       public void onAnimationEnd(Animation animation) { 
        // TODO Auto-generated method stub 
         ((View) listener2).startAnimation(animFadeout3); 
       } 
      }); 


      animFadeout3.setAnimationListener(new AnimationListener() { 

       @Override 
       public void onAnimationStart(Animation animation) { 
        // TODO Auto-generated method stub 
       } 

       @Override 
       public void onAnimationRepeat(Animation animation) { 
        // TODO Auto-generated method stub 
       } 

       @Override 
       public void onAnimationEnd(Animation animation) { 
        // TODO Auto-generated method stub 

          Intent intent = new Intent(menu.this, play.class); 
          intent.putExtra(KEY_ANIM, target_op); 
          startActivity(intent); 
          menu.this.finish(); 


       } 
      }); 

我被放在動畫在那裏，所以當listener1按鈕組點擊它會顯示淡出動畫時再listener1動畫結束LISTENER2動漫秀聽衆等等3

，這是從logcat的

對不起，如果有我的代碼，因爲我是問在這裏糾正我的代碼，由於錯誤提前

Answer 1

你投onClickListenner更改爲View，並嘗試導致錯誤的startAnimation。

應該調用它的觀點：

view.startAnimation(animFadeout1); 

---

與您的代碼的其他問題：

既然你與所有這些按鈕的工作會更容易些，使活動implments OnClickListener：

public class menu extends Activity implements View.OnClickListener{...} 

所有的按鈕都使用相同的ID，所以它會表現sa我爲所有按鈕。

您需要使用不同的ID，並讓他們使用相同的監聽器：

button1= (Button)findViewById(R.id.button_one); 
button1.setOnClickListener(this);   
button2= (Button)findViewById(R.id.button_two); 
button2.setOnClickListener(this); 

然後使用一個開關的情況下提供基於按鈕標識不同的邏輯。

@Override 
    public void onClick(View view) { 
     //To identify the correct widget, use the getId() method on the view argument 
     int id = view.getId(); 
     switch (id) { 
      case R.id.button_one: 
       //viewOne clicked 
       break; 
      case R.id.button_two: 
       //And so on... 
     } 
    } 

你爲例如多個按鈕的情況下：

case R.id.button_one, R.id.button_two , R.id.button_three, R.id.button_four: 

而且你的動畫是多餘的，良好的編碼習慣要你避免重複。
