코드에서 사용자 지정 어댑터를 가져 오려고합니다. 나는 튜토리얼을 따라 갔지만 뭔가 잘못된 것이있다. 사용자 지정 어댑터에서 생성자가 정의되지 않았습니다.

내 mainActivity에서 나는이 작업을 수행 :ListView list;
CustomListAdapter adapter;
public MainActivity CustomListView = null;
public ArrayList<Players> CustomListViewValuesArr = new ArrayList<Players>();
//button handlers newmatch_players_home
public void addSpelerNu(View button) {
Log.d("WedstrijdID buiten de create", ""+wedstrijdId);
Log.d("id return team thuis", ""+thuisTeamId);
//thuisteam
final EditText shirtNummer = (EditText) findViewById(R.id.shirtThuis);
String nummerShirt = shirtNummer.getText().toString();
int shirtSpeler = Integer.parseInt(nummerShirt);
final EditText spelerNaam = (EditText) findViewById(R.id.naamThuis);
String naamSpeler = spelerNaam.getText().toString();
Integer wedstrijdSpelerId = (int) (long) wedstrijdId;
SqLiteHelper db = new SqLiteHelper(this);
db.addSpeler(new Players(shirtSpeler, naamSpeler, thuisTeamId, wedstrijdSpelerId));
Log.d("Toevoegen speler THUIS", ">> BEGIN");
Log.d("Toevoegen speler", "Shirt = "+nummerShirt+" Naam = "+naamSpeler +" Team ="+thuisTeamId+" Wedstrijd ="+wedstrijdSpelerId);
Log.d("Toevoegen speler", ">> EIND");
shirtNummer.setText(null);
spelerNaam.setText(null);
CustomListView = this;
/******** Take some data in Arraylist (CustomListViewValuesArr) ***********/
List <Players> CustomListViewValuesArr = new ArrayList<Players>();
Resources res =getResources();
list= (ListView)findViewById(R.id.listHome);
/**************** Create Custom Adapter *********/
adapter=new CustomListAdapter(CustomListView, CustomListViewValuesArr,res);
list.setAdapter(adapter);
}
하지만 이클립스 나는이를보고 계속 알림 :
생성자 CustomListAdapter는
그래서 난이 사용자 정의 어댑터를 사용하는 것을 잊었다는 것입니다
을 정의되지?private ArrayList< Players>data;
public void CustomAdapter(Activity a, ArrayList < Players> d,Resources resLocal) {
activity = a;
data=d;
res = resLocal;
/*********** Layout inflator to call external xml layout() ***********/
inflater = (LayoutInflater)activity.
getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
이 없다'대신 CustomAdapter''의 CustomListAdapter'과'void'를 제거 않기 때문에
void를 제거합니다. – Luksprogthnx! 내 사용자 정의보기에서 '데이터 없음'이 표시됩니다. 그래서 사용자 정의보기가 작동 중입니다 :) –
