listview的多条目加载的适配器

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;

}
@Override
public int getCount() {
return list.size();
}

@Override
public Object getItem(int position) {
return list.get(position);
}

@Override
public 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;

}

@Override
public 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);
}
}
