Gridview滚动 - 回收视图

Question

我试图回收gridview项目，因为目前的解决方案工作，但是laggy和吃掉资源。但是，我无法弄清楚如何。 Android开发者网站的例子并不适合我。

我getview（）方法：

public View getView(int position, View paramView, ViewGroup paramViewGroup) { 
    long starttime = System.currentTimeMillis(); 

View localView = MMWeb.this.getLayoutInflater().inflate(R.layout.grid_item, null); 
TextView localTextView = (TextView)localView.findViewById(2131034115); 
ImageView localImageView = (ImageView)localView.findViewById(2131034114); 

cItem = items.get(position); 
cItem.add(Integer.toString(position)); 
localTextView.setText(getItemName()); 
Bitmap localBitmap = d.getImage(cItem.get(3), cItem.get(2)); 
localImageView.setImageBitmap(localBitmap); 
Common.toLog("getView took "+ (System.currentTimeMillis() - starttime) + " ms"); 
return localView; } 

有人能指出我在正确的方向？任何建议如何解决这个将不胜感激！

只需使用paramView，这是adapterview传递的可重用视图，因为它在屏幕上不再可见。

if (paramView == null) { 
    // inflate a new view into paramView. 
    paramView = MMWeb.this.getLayoutInflater().inflate(R.layout.grid_item, null); 
} 
// fill the paramView 
TextView localTextView = (TextView)paramView .findViewById(2131034115); 
ImageView localImageView = (ImageView)paramView .findViewById(2131034114); 

cItem = items.get(position); 
cItem.add(Integer.toString(position)); 
localTextView.setText(getItemName()); 
Bitmap localBitmap = d.getImage(cItem.get(3), cItem.get(2)); 
localImageView.setImageBitmap(localBitmap); 

return paramView;
