В моем коде должно быть что-то неявное или неправильное, чтобы ListView ничего не показывал.CustomAdapter и ListView
Я следовал этому примеру Use array adapter with more views in row in listview
[MyModel]
package com.example.apinato.layoutexample;
public class MyModel {
private String name;
private String surname;
private String ranking;
public MyModel(String name, String address, String ranking) {
this.name = name;
this.surname = address;
this.ranking = ranking;
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setSurname(String surname) {
this.surname = surname;
}
public String getSurname() {
return surname;
}
public void setRanking(String ranking) {
this.surname= ranking;
}
public String getRanking() {
return ranking;
}
}
[myCustomAdapter]

public MyCustomAdapter(Context context, int position, ArrayList<com.example.apinato.layoutexample.MyModel> list) {
super(context, position);
this.context = context;
this.list = list;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
// Get a new instance of the row layout view
LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
rowView = inflater.inflate(R.layout.row, parent, false);

TextView _ranking = (TextView) rowView.findViewById(R.id.ranking1);
//added according to your suggestions
com.example.apinato.layoutexample.MyModel myModel = (com.example.apinato.layoutexample.MyModel) list.get(position);
_name.setText(myModel.getName());
_surname .setText(myModel.getName());

Вы не видите '_name.setText()' в getView – Blackbelt
В вашем пользовательском адаптере вы не устанавливаете значение для '' _name, _surname и _ranking'', поэтому он не отображает ничего –
и все еще не работает после добавления те? –
