Android GridView適配器調用幾個getview（）爲零位

Android gridview適配器調用位置零的幾個時間getView()。下面你可以看到我的xml代碼和日誌。任何人都可以在這段代碼中看到任何錯誤的東西？Android GridView適配器調用幾個getview（）爲零位

<GridView 
    android:id="@+id/reward_grid" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" 
    android:layout_centerInParent="true" 
    android:background="@color/transparent" 
    android:horizontalSpacing="@dimen/reward_negative_space_medium" 
    android:listSelector="@color/Transparent" 
    android:numColumns="2" 
    android:scrollbars="none" 
    android:stretchMode="columnWidth" 
    android:verticalSpacing="@dimen/reward_negative_space_medium" > 
</GridView>

我的適配器代碼是 @覆蓋公共查看getView（INT位置，查看convertVieww，ViewGroup以及母公司）{

if(ShopBitesLog.IS_DEBUG_ENABLED) 
     Log.d(Tag, "Getview calling for position : "+ position); 


    if (convertView == null) { 

     holder = new ViewHolder(); 

     final View convertView = inflator.inflate(R.layout.reward_grid_items, null); 

     holder.rewardGriditemTopImg = (ImageView)convertView 
       .findViewById(R.id.reward_grid_top_Img); 

     holder.rewardGriditemBites = (TextView)convertView 
       .findViewById(R.id.reward_grid_pointsTxt); 

     holder.reward_manin_linear = (RelativeLayout)convertView 
       .findViewById(R.id.reward_manin_linear); 

     holder.relative_reward_image = (RelativeLayout)convertView.findViewById(R.id.relative_reward_image); 

     holder.rewardText = (TextView)convertView.findViewById(R.id.rewardText); 

     holder.reward_first_relative=(RelativeLayout)convertView.findViewById(R.id.reward_first_relative); 

     holder.reward_second_relative=(RelativeLayout)convertView.findViewById(R.id.reward_second_relative); 


     convertView.setTag(holder); 

    } else { 

     holder = (ViewHolder)convertView.getTag(); 

    } 

    if (rewardList.get(position).isAnnouncement()) { 

     holder.reward_second_relative.setVisibility(View.VISIBLE); 
     holder.reward_first_relative.setVisibility(View.GONE); 

     // holder.rewardGriditemTopImg.setImageResource(R.drawable.charity); 
     // holder.rewardText.setVisibility(View.VISIBLE); 

     holder.rewardText.setText(rewardList.get(position).getRewardText()); 

     // holder.relative_reward_image.setVisibility(View.INVISIBLE); 


    } else { 

     holder.reward_first_relative.setVisibility(View.VISIBLE); 
     holder.reward_second_relative.setVisibility(View.GONE); 


     // holder.relative_reward_image.setVisibility(View.VISIBLE); 

     // holder.rewardText.setVisibility(View.INVISIBLE); 

     holder.rewardGriditemBites.setText(rewardList.get(position).getShop_bites() + " " 
       + "bites"); 
     imageBitmapLoader.DisplayImage(rewardList.get(position).getReward_image(), 0, 
       holder.rewardGriditemTopImg, true); 

    } 
    return convertView; 
}

請張貼您的代碼！ – 2013-03-01 11:53:28

最有可能沒有錯你的代碼。無法保證AdapterView將調用適配器的getView()多少次。您的工作僅僅是爲了使getView()變得非常快。
