自定义适配器(布局文件一个TextView就可以)

package com.example.day1;

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

import java.util.HashMap;
import java.util.List;

public class MyAdapter extends BaseAdapter {
    Context context;
    List<HashMap<String,String>> list;

    public MyAdapter(Context context, List<HashMap<String, String>> list) {
        this.context = context;
        this.list = list;
    }

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

    @Override
    public Object getItem(int position) {
        return null;
    }

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

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;
        if (convertView == null){
            viewHolder = new ViewHolder();
            convertView = View.inflate(context, R.layout.item, null);
            viewHolder.t = convertView.findViewById(R.id.t);
            convertView.setTag(viewHolder);
        }else{
            viewHolder = (ViewHolder) convertView.getTag();
        }
        HashMap<String, String> map = list.get(position);
        if (convertView != null){
            viewHolder.t.setText(map.get("t"));
        }
        return convertView;
    }
    public class ViewHolder{
        TextView t;
    }

}
