Gridview滚动- recycleview

Question

我正在尝试回收网格视图项目，因为当前的解决方案有效，但滞后并消耗资源。然而，我想不出该怎么做。android开发人员站点的示例对我不起作用。

我的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; }

有人能给我指个方向吗？？任何关于如何解决这个问题的建议都将不胜感激！

只需使用paramView，这是您的适配器视图传递的可重用视图，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;
