从零开始的体温app开发（adapter2）

listview 对每一条设置监听事件

package adapter;

import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.TextView;

import com.example.myapplication.R;
import com.example.myapplication.SecondActivity;
import com.example.myapplication.ThirdActivity;

import java.util.List;

import bean.User;
import bean.User2;

public class UserListAdapter2 extends BaseAdapter  {
    private final Context context;
    private final List<User2> userList2;
    public UserListAdapter2(Context context, List<User2> userList2) {
        this.context=context;
        this.userList2=userList2;
    }

    @Override
    public int getCount() {
        return userList2.size();
    }

    @Override
    public Object getItem(int i) {
        return userList2.get(i);
    }

    @Override
    public long getItemId(int i) {
        return 0;
    }

    @Override
    public View getView(int i, View convertView, ViewGroup parent) {
        if(convertView==null){
            convertView=View.inflate(context,R.layout.item_user2,null);
        }
        TextView bu=convertView.findViewById(R.id.btn5);
        bu.setTag(i);
        bu.setText(userList2.get(i).getCl()+"-"+userList2.get(i).getName()+"-"+userList2.get(i).getNum());
        return convertView;
    }

}
