這個嵌套類會導致內存泄漏嗎？

這是我目前的學習練習，因爲我最終要做的是創建一個GestureListener對象並將其重新分配給所有新的MyTouchView對象。這個嵌套類會導致內存泄漏嗎？

（爲了簡便起見，我省略的代碼一些必要的比特。）

的問題是：爲下面的代碼，將在（可能）許多GestureListener對象從最後確定預防嗎？如您所見，會創建大量GestureListener對象 - 每次用戶翻頁時都會有一個對象。

public class MyActivity extends Activity 

    // Widgets 
    private ViewPager mViewPager; 
    private TextView mTVPageCount; 
    private TextView mTVTitle; 
    private Button mBShare; 
    private Button mBBack; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     mTVPageCount = (TextView) findViewById(R.id.pagecount); 
     mTVTitle = (TextView) findViewById(R.id.title); 
     mBShare = (Button) findViewById(R.id.share); 
     mBBack = (Button) findViewById(R.id.back); 
    } 

    private class TouchAdapter extends PagerAdapter { 

     //pre-create neighboring views 
     @Override 
     public View instantiateItem(ViewGroup container, int position) { 
       MyTouchView img = new MyTouchView(container.getContext()); 
       img.setOnDoubleTapListener(new GestureListener()); 
       return img; 
     } 
    } 

    private class GestureListener implements GestureDetector.OnDoubleTapListener { 

     @Override 
     public boolean onSingleTapConfirmed(MotionEvent e) { 
      int iVisibility = mTVPageCount.getVisibility(); 
      int iNewVisibility; 
      if (iVisibility == View.VISIBLE) { 
       iNewVisibility = View.GONE; 
      } else { 
       iNewVisibility = View.VISIBLE; 
      } 
      mTVPageCount.setVisibility(iNewVisibility); 
      mTVTitle.setVisibility(iNewVisibility); 
      mBShare.setVisibility(iNewVisibility); 
      mBBack.setVisibility(iNewVisibility); 
      return true; 
     } 
    } 
}

上面的代碼是否工作？你什麼時候將'img'附加到容器？你實施'destroyItem'嗎？ – 2014-09-11 02:43:26

'img'被返回，所以它是容器。 'destroyItem'被實現，它只是'container.removeView（（View）object）;' – 2014-09-11 18:04:31
