你在适配器中传入context就可以了。
public class ProductListAdapter extends BaseAdapter {
private Context context;
private List<String> listData;
private ViewHolderProduct viewHolderProduct;
public ProductListAdapter(Context context,List<String> listData){
this.context = context;
this.listData = listData;
}
@Override
public int getCount() {
return listData == null ? 0 : listData.size();
}
@Override
public Object getItem(int position) {
return listData == null ? null : listData.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if(convertView == null || convertView.getTag() == null){
viewHolderProduct = new ViewHolderProduct();
convertView = LayoutInflater.from(context).inflate(R.layout.product_item_layout,null);
viewHolderProduct.iv_pro_pic = (ImageView) convertView.findViewById(R.id.iv_imageView);
viewHolderProduct.tv_pro_date = (TextView) convertView.findViewById(R.id.tv_pro_date);
viewHolderProduct.tv_pro_desc = (TextView) convertView.findViewById(R.id.tv_pro_desc);
viewHolderProduct.tv_pro_from = (TextView) convertView.findViewById(R.id.tv_pro_from);
viewHolderProduct.tv_pro_name = (TextView) convertView.findViewById(R.id.tv_pro_name);
viewHolderProduct.tv_pro_number = (TextView) convertView.findViewById(R.id.tv_pro_number);
viewHolderProduct.tv_pro_price = (TextView) convertView.findViewById(R.id.tv_pro_price);
convertView.setTag(viewHolderProduct);
}else{
viewHolderProduct = (ViewHolderProduct) convertView.getTag();
}
viewHolderProduct.tv_pro_price.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(context, LoginActivity.class);
context.startActivity(intent);
}
});
return convertView;
}
class ViewHolderProduct{
TextView tv_pro_number,tv_pro_name,tv_pro_desc,tv_pro_from,tv_pro_date,tv_pro_price;
ImageView iv_pro_pic;
}
}
