Android ListView展示不同的布局

由于item中converView的复用，所以ListView在展示不同布局的时候，需要在adapter里复写以下方法：getViewTypeCount()和getItemViewType(int position)。有了这个思路就很简单了。adapter代码如下：

package com.example.dyk.listviewtest;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.TextView;

import java.util.List;

public class Adapter extends BaseAdapter {

    private List<Bean> list;
    private Context mContext;
    private LayoutInflater mInflater;
    private ViewHolder holder;

    public Adapter(List<Bean> list, Context mContext) {
        this.list = list;
        this.mContext = mContext;
        mInflater = LayoutInflater.from(mContext);
    }

    public void notifyDataSetChanged(List<Bean> list) {
        this.list = list;
        super.notifyDataSetChanged();
    }

    @Override
    public int getCount() {
        return list == null ? 0 : list.size();
    }

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

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public int getViewTypeCount() {
        return 2;
    }

    @Override
    public int getItemViewType(int position) {
        if (position == 0) {
            return 0;
        } else {
            return 1;
        }
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (getItemViewType(position) == 0) {
            convertView = mInflater.inflate(R.layout.item, null);
        } else {
            if (convertView == null) {
                holder = new ViewHolder();
                convertView = mInflater.inflate(R.layout.items, null);
                holder.name = (TextView) convertView.findViewById(R.id.name);
                holder.age = (TextView) convertView.findViewById(R.id.age);
                convertView.setTag(holder);
            } else {
                holder = (ViewHolder) convertView.getTag();
            }

            Bean bean = list.get(position);
            holder.name.setText(bean.getName());
            holder.age.setText(bean.getAge());
        }
        return convertView;
    }

    public class ViewHolder {
        TextView name;
        TextView age;
    }
}
