CommonAdapter直接上代码

调用方法

  ProductionAdapter   adapter = new ProductionAdapter(orderlList, R.layout.layout_order);
  listView.setAdapter(adapter);

  public class ProductionAdapter extends CommonAdapter<ProductListResult.DataEntity.ModelListEntity> {
        public ProductionAdapter(List<ProductListResult.DataEntity.ModelListEntity> mDatas, int itemLayoutId) {
            super(mDatas, itemLayoutId);
            L.e("ProductionAdapter");
        }

        @Override
        public void convert(int position,BaseViewHolder helper, ProductListResult.DataEntity.ModelListEntity item) {
            RelativeLayout reView = helper.getView(R.id.item_button_layout);
            ImageView productImg = helper.getView(R.id.product_img);
            reView.setVisibility(View.GONE);
            helper.setText(R.id.product_name, item.getTitle());
            helper.setText(R.id.product_price, item.getPrice());

一个ListView的Itme放不定个数进度条
    public class ListViewAdapter extends CommonAdapter<ProgressResult.DataEntity.OrderlListEntity>{
