CommonAdapter直接上代码
public abstract class CommonAdapter<T> extends BaseAdapter {

protected final int mItemLayoutId;
public CommonAdapter(List<T> mDatas, int itemLayoutId) {

BaseViewHolder 直接上代码
public class BaseViewHolder {

/**

}
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());
helper.setText(R.id.product_norms, item.getBaseInfo());
helper.setText(R.id.product_number, item.getNumber() + "");
helper.setText(R.id.id_tv_information, item.getInfo());
ImageLoader.getInstance().displayImage(item.getPic(), productImg, ImageLoadOptions.getOptions());
}
}

一个ListView的Itme放不定个数进度条
public class ListViewAdapter extends CommonAdapter<ProgressResult.DataEntity.OrderlListEntity>{
public ListViewAdapter(List<ProgressResult.DataEntity.OrderlListEntity> mDatas, int itemLayoutId) {
super(mDatas, itemLayoutId);
}
@Override
public void convert(int position, BaseViewHolder helper, ProgressResult.DataEntity.OrderlListEntity item) {
LinearLayout linearlayout = helper.getView(R.id.id_list_porgress);
linearlayout.removeAllViews();
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,UIUtils.dip2px(30));
lp.setMargins(10,10,10,10);
List<ProgressResult.DataEntity.OrderlListEntity.ProgressEntity> progressList=null;
if (item!=null){
progressList = item.getProgress();
}
if (progressList!=null){
for (int i = 0; i < progressList.size(); i++) {
View view=getMyProgressView();
ProgressBar progress = (ProgressBar) view.findViewById(R.id.my_progress);
TextView textProgress = (TextView) view.findViewById(R.id.tv_progress);
progress.setMax(mFlowTotalCount);
progress.setProgress(progressList.get(i).getCurrentFlow());
textProgress.setText(progressList.get(i).getFlowInfo());
linearlayout.addView(view, lp);
}
}
}
public View getMyProgressView() {
View inf_rel = LayoutInflater.from(mContext).inflate(R.layout.item_myprogress, null);
return inf_rel;
}
}
