这是gridview的adapter

/**

publicclassGoodsDetailSkuGridAdapterextendsBaseAdapter{
privateListval=newArrayList();

privateintclickPosition=-1;

publicGoodsDetailSkuGridAdapter(Listval){
this.val=val;
}

@Override
publicintgetCount(){
returnval.size();
}

@Override
publicObjectgetItem(intposition){
returnnull;
}

@Override
publiclonggetItemId(intposition){
return0;
}

publicvoidsetClickPosition(intposition){
this.clickPosition=position;
}


@Override
publicViewgetView(finalintposition,ViewconvertView,ViewGroupparent){
finalViewHolderholder;
if(convertView==null){
holder=newViewHolder();
convertView=UiUtils.inflate(R.layout.item_sku_text_normal);
holder.tv_name=(TextView)convertView.findViewById(R.id.tv_name);
convertView.setTag(holder);
}else{
holder=(ViewHolder)convertView.getTag();
}
holder.tv_name.setText(val.get(position).rename);

if(position==clickPosition){
//Toast.makeText(UiUtils.getContext(),"执行刷新",Toast.LENGTH_SHORT).show();
holder.tv_name.setBackgroundResource(R.drawable.shape_sku_text_pressed_bg);
holder.tv_name.setTextColor(Color.WHITE);
}else{
holder.tv_name.setBackgroundResource(R.drawable.shape_sku_text_normal_bg);
holder.tv_name.setTextColor(Color.rgb(109,109,109));
}

returnconvertView;
}

privateclassViewHolder{
publicTextViewtv_name;
}
}

其他方法都没事，只有adapter.notifyDataSetChanged();没有用。求各路大神给解决方法。

现在是要实现条目的点击效果，点击的地方变红，adapter.notifyDataSetChanged();这个方法不执行，无法刷新。

正确是方式应该是ListView的每个Item都要写成局部成员变量并且加final修饰，具体代码如下：

//privateGoodsDetailSkuGridAdapteradapter;//这一行代码注释了。

...

@Override
publicViewgetView(finalintposition,ViewconvertView,ViewGroupparent){
ViewHolderholder;
if(convertView==null){
holder=newViewHolder();
convertView=UiUtils.inflate(R.layout.item_goods_detail_sku);
holder.tv_dialog_sku_title=(TextView)convertView.findViewById(R.id.tv_dialog_sku_title);
holder.gv_dialog_properties=(MyGridView)convertView.findViewById(R.id.gv_dialog_properties);
convertView.setTag(holder);
}else{
holder=(ViewHolder)convertView.getTag();
}
holder.tv_dialog_sku_title.setText(skuArray.get(position).name);
finalGoodsDetailSkuGridAdapteradapter=newGoodsDetailSkuGridAdapter(skuArray.get(position).val);
holder.gv_dialog_properties.setAdapter(adapter);

holder.gv_dialog_properties.setOnItemClickListener(newAdapterView.OnItemClickListener(){
@Override
publicvoidonItemClick(AdapterViewparent,Viewview,intsposition,longid){
if(skuArray.get(position).title.equals("chima")){
adapter.setClickPosition(sposition);
size=Integer.parseInt(skuArray.get(position).val.get(sposition).id);
intsizeId=skuArray.get(position).id;
skuListener.setSkuSize(sizeId+":"+size);
adapter.notifyDataSetChanged();
}elseif(skuArray.get(position).title.equals("yanse")){
adapter.setClickPosition(sposition);
color=Integer.parseInt(skuArray.get(position).val.get(sposition).id);
intcolorId=skuArray.get(position).id;
skuListener.setSkuColor(colorId+":"+color);
adapter.notifyDataSetChanged();
}elseif(skuArray.get(position).title.equals("kuanshi")){
adapter.setClickPosition(sposition);
style=Integer.parseInt(skuArray.get(position).val.get(sposition).id);
intstyleId=skuArray.get(position).id;
skuListener.setSkuStyle(styleId+":"+style);
adapter.notifyDataSetChanged();
}
}
});
returnconvertView;
}
