無法暫停活動？

我是Android開發新手。我編寫了這段代碼，但我無法弄清楚是什麼導致我的應用程序崩潰。它告訴我該活動無法暫停。我確信這是我要拋棄的東西。我寫過非常相似的代碼，這些代碼在過去都有效，所以我不確定從哪裏開始。無法暫停活動？

SplashActivity.java

public class SplashActivity extends Activity 
{ 
    @Override 
    protected void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_splash); 

     ImageView logo = (ImageView) findViewById(R.id.ImageViewLogo); 
     Animation twistIn = AnimationUtils.loadAnimation(this, R.anim.twist_in); 
     logo.startAnimation(twistIn); 
     twistIn.setAnimationListener(new AnimationListener() 
     { 
      public void onAnimationStart(Animation animation) 
      { 
       return; // do nothing 
      } 
      public void onAnimationRepeat(Animation animation) 
      { 
       return; // do nothing 
      } 
      public void onAnimationEnd(Animation animation) 
      { 
       startActivity(new Intent(SplashActivity.this, MenuActivity.class)); 
       SplashActivity.this.finish(); 
      } 
     }); 
    } 

    @Override 
    protected void onPause() 
    { 
     super.onPause(); 

     TextView logo = (TextView) findViewById(R.id.ImageViewLogo); 
     logo.clearAnimation(); 
    } 
}

而這裏的logcat的抱怨：

使用

ImageView logo = (ImageView) findViewById(R.id.ImageViewLogo);

，而不是

在 onPause()方法

TextView logo = (TextView) findViewById(R.id.ImageViewLogo);

，因爲您正在嘗試投放ImageView（你在XML的佈局都添加）到TextView

噢 - 嗬 - 嗬哇。謝謝！ – 2013-04-04 06:22:23

您正在嘗試將ImageView與Textview引用因此它會拋出ClassCastException

更改此

TextView logo = (TextView) findViewById(R.id.ImageViewLogo);

這個

ImageView logo = (ImageView) findViewById(R.id.ImageViewLogo);

見的OnCreate這一行（）方法

ImageView logo = (ImageView) findViewById(R.id.ImageViewLogo);

而且的onPause（）方法使用已經寫TextView的，而不是ImageView像上面

TextView logo = (TextView) findViewById(R.id.ImageViewLogo);

因此，這是給你classcast例外..更改的TextView到ImageView的
