Android Studio:

How do I add texviews to this listview?

public class Scoreboard extends Activity{ public static ArrayAdapter adapter2; public static ArrayAdapter adapter3; public static ArrayList list2 = new ArrayList<>(); public static ArrayList list3 = new ArrayList<>(); ListView selectView3; ListView selectView4; public static int losses1 = 0; public static int ties1 = 0; public static int losses2 = 0; public static int ties2 = 0; public final static String value2 = "EMPTY_VALUE2"; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.scoreboard); selectView3 = findViewById(R.id.selectview3); selectView3.setVisibility(View.VISIBLE); selectView4 = findViewById(R.id.selectview4); selectView4.setVisibility(View.VISIBLE); Intent in = getIntent(); int score = in.getIntExtra("VARIABLE", 0); //Using adapter for ListView menu   adapter2 = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, list2); selectView3.setAdapter(adapter2); //Using intent to retrieve string from AddPlayer Activity  Intent i = getIntent(); String data = i.getStringExtra("text_key"); if(data != null){ list2.add("Player 1"+" "+"Name: "+data+" "+"Wins: " +" "+"Losses: "+ losses1+" "+"Ties: "+ ties1); } if(data != ""){ changeList(); } adapter3 = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, list3); selectView4.setAdapter(adapter3); Intent intent = getIntent(); String extra= intent.getStringExtra(value2); if(extra != null) { list3.add("Player 2" + " " + "Name: " + extra + " " + "Wins: " + " " + "Losses: " + losses2 + " " + "Ties: " + ties2); } if(data != ""){ changeList(); } } public void changeList() { adapter2.notifyDataSetChanged(); } }
