    String number;
    String name;
    String status;

    public long getId() {
        return id;
    }

    public void setId(long id) {
        this.id = id;
    }

    public String getNumber() {
        return number;
    }

    public void setNumber(String number) {
        this.number = number;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getStatus() {
        return status;
    }

    public void setStatus(String tweet) {
        this.status = tweet;
    }

Créez un fichier de mise en page pour la ligne ListView

Créez un adaptateur personnalisé Créez CustomAdapter.java, ajoutez ce qui suit

package com.example.honka_1;

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.ArrayList;

public class CustomAdapter extends BaseAdapter{
    Context context;
    LayoutInflater layoutInflater = null;
    ArrayList studentList;

    public CustomAdapter(Context context) {
        this.context = context;
        this.layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }

    public void setTweetList(ArrayList tweetList) {
        this.studentList = tweetList;
    }

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

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

    @Override
    public long getItemId(int position) {
        return studentList.get(position).getId();
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        convertView = layoutInflater.inflate(R.layout.studentrow,parent,false);
        ((TextView)convertView.findViewById(R.id.id)).setText(studentList.get(position).getNumber());
        ((TextView)convertView.findViewById(R.id.name)).setText(studentList.get(position).getName());
        ((TextView)convertView.findViewById(R.id.status)).setText(studentList.get(position).getStatus());

        return convertView;
    }
}

4 Définir ListView dans Activity ou Fragment

5 Réglez l'adaptateur sur ListView

public class Main2Activity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main2);

        Intent intent = this.getIntent();
        Integer selectedDay = intent.getIntExtra("selectedDay",0);


        Log.i("test", selectedDay.toString());

        ListView listView = (ListView)findViewById(R.id.listView);

        ArrayList list = new ArrayList<>();
        CustomAdapter adapter = new CustomAdapter(Main2Activity.this);
        adapter.setTweetList(list);
        listView.setAdapter(adapter);

        Student student = new Student();
        student.setNumber("1");
 student.setName ("Wada");
 student.setStatus ("participation");
        list.add(student);

        adapter.notifyDataSetChanged();



    }
