描述：这是一个listview多条目加载的适配器，为了能更高效的利用时间和完成任务，所以。。。额其实主要是自己很懒，所以他就出生了…

用法：粘贴到自己定义好的适配器的类里面，因为里面的布局就两种，而且布局是我自己写的，所以粘贴的时候就自己改一下吧。

private final int type_1 = 0;private final int type_2 = 1;private Context context;private List<HomeBean.ResultBean.DataBean> list = new ArrayList<>();private HomePresenter homePresenter;public HomeAdapter(Context context) {    this.context = context;}public void getHomePresenter(HomePresenter homePresenter) {    this.homePresenter = homePresenter;}@Overridepublic int getCount() {    return list.size();}@Overridepublic Object getItem(int position) {    return list.get(position);}@Overridepublic long getItemId(int position) {    return position;}

//判断什么情况下分别加载条目（这里分别是list的下标为基数。偶数）
@Override
public int getItemViewType(int position) {
if (position % 2 > 0) {
return 0;
} else {
return 1;
}
}
//你的条目有几种类型
@Override
public int getViewTypeCount() {
return 2;
}

@Overridepublic View getView(int position, View convertView, ViewGroup parent) {    Holder holder;    int type = getItemViewType(position);    if (convertView == null) {        holder = new Holder();        if (type == type_1) {            convertView = convertView.inflate(context, R.layout.home_listitem, null);            holder.imageView = (ImageView) convertView.findViewById(R.id.tu);            holder.textView = (TextView) convertView.findViewById(R.id.te);        }else {                convertView = convertView.inflate(context, R.layout.home_listitem2, null);            holder.textView = (TextView) convertView.findViewById(R.id.te1);            holder.imageView = (ImageView) convertView.findViewById(R.id.tu1);            holder.imageView2 = (ImageView) convertView.findViewById(R.id.tu2);            holder.imageView3 = (ImageView) convertView.findViewById(R.id.tu3);        }          convertView.setTag(holder);        } else {                 holder= (Holder) convertView.getTag();    }    holder.textView.setText(list.get(position).getTitle());    homePresenter.getImageData(holder.imageView, list.get(position).getThumbnail_pic_s());    holder.textView.setText(list.get(position).getTitle());    homePresenter.getImageData(holder.imageView, list.get(position).getThumbnail_pic_s());    homePresenter.getImageData(holder.imageView2, list.get(position).getThumbnail_pic_s02());    homePresenter.getImageData(holder.imageView3, list.get(position).getThumbnail_pic_s03());        return convertView;}static class Holder {    TextView textView;    ImageView imageView;    ImageView imageView2;    ImageView imageView3;}

//这个方法的目的是在MainActivity中将list传到适配器所以要在MainActivity中调用并将list数据传入

public void getData(List<HomeBean.ResultBean.DataBean> data) {    if (data != null) {        list.addAll(data);    }}
