Wiem, że już na to odpowiedzieliśmy... ale chciałem podać pełniejszy przykład.

W moim przykładzie ListActivity, który wyświetli nasze niestandardowe ListView nazywa się OptionsActivity, ponieważ w moim projekcie to Activity wyświetli różne opcje, które mój użytkownik może ustawić, aby kontrolować moją aplikację. Istnieją dwa typy elementów listy, jeden typ elementu listy ma po prostu TextView, a drugi typ elementu listy ma po prostu Button. Możesz umieścić dowolne widżety, które lubisz wewnątrz każdego typu pozycji listy, ale zachowałem ten przykład proste.

Metoda getItemView() sprawdza, które pozycje listy powinny być typu 1 lub typu 2. Zgodnie z moimi statycznymi intami, które zdefiniowałem na górze, pierwsze 5 pozycji listy będzie List item type 1, a ostatnie 5 pozycji listy będzie List item type 2. Więc jeśli skompilujesz i uruchomisz to, będziesz miał ListView, który zawiera pięć elementów, które zawierają Button, a następnie pięć elementów, które zawierają TextView.

Poniżej znajduje się kod Activity, plik XML activity I plik xml dla każdego elementu listy Typ.

Java:

public class OptionsActivity extends ListActivity {

    private static final int LIST_ITEM_TYPE_1 = 0;
    private static final int LIST_ITEM_TYPE_2 = 1;
    private static final int LIST_ITEM_TYPE_COUNT = 2;

    private static final int LIST_ITEM_COUNT = 10;
    // The first five list items will be list item type 1 
    // and the last five will be list item type 2
    private static final int LIST_ITEM_TYPE_1_COUNT = 5;

    private MyCustomAdapter mAdapter;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        mAdapter = new MyCustomAdapter();
        for (int i = 0; i < LIST_ITEM_COUNT; i++) {
          if (i < LIST_ITEM_TYPE_1_COUNT)
            mAdapter.addItem("item type 1");
          else
            mAdapter.addItem("item type 2");
        }
        setListAdapter(mAdapter);
    }

Google ma przykład o nazwie EfficientAdapter, który moim zdaniem jest najlepszym prostym przykładem wdrażania niestandardowych adapterów. http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/view/List14.html @CommonsWare napisał dobre wyjaśnienie wzorców użytych w powyższym przykładzie http://commonsware.com/Android/excerpt.pdf

Możesz spojrzeć na tę próbkę w oficjalnym ApiDemos. Pokazuje jak rozszerzyć BaseAdapter i zastosować ją do ListView. Następnie wystarczy spojrzeć na odniesienie dla BaseAdapter i spróbować zrozumieć, co robi każda metoda (w tym te odziedziczone) i kiedy/jak jej używać.

Również, Google jest twoim przyjacielem :).

Sprawdź ten link , w bardzo prosty sposób za pomocą convertView możemy uzyskać układ wiersza, który będzie wyświetlany w listview(czyli parentView).

View v = convertView;

if (v == null) {

    LayoutInflater vi;
    vi = LayoutInflater.from(getContext());
    v = vi.inflate(R.layout.itemlistrow, null);

}

Korzystając z pozycji, można uzyskać obiekty List<Item>.

Item p = items.get(position);

Następnie będziemy musieli ustawić żądane szczegóły obiektu do zidentyfikowanych widżetów formularza.

if (p != null) {

    TextView tt = (TextView) v.findViewById(R.id.id);
    TextView tt1 = (TextView) v.findViewById(R.id.categoryId);
    TextView tt3 = (TextView) v.findViewById(R.id.description);

    if (tt != null) {
        tt.setText(p.getId());
    }
    if (tt1 != null) {

        tt1.setText(p.getCategory().getId());
    }
    if (tt3 != null) {

        tt3.setText(p.getDescription());
    }
}

Następnie zwróci zbudowany widok, który zostanie dołączony do parentView (który jest ListView/GridView).

Oto kompletny krok po kroku, aby utworzyć niestandardowy adapter do widoku listy -

Https://www.caveofprogramming.com/guest-posts/custom-listview-with-imageview-and-textview-in-android.html

public class CustomAdapter extends BaseAdapter{   
    String [] result;
    Context context;
 int [] imageId;
      private static LayoutInflater inflater=null;
    public CustomAdapter(MainActivity mainActivity, String[] prgmNameList, int[] prgmImages) {
        // TODO Auto-generated constructor stub
        result=prgmNameList;
        context=mainActivity;
        imageId=prgmImages;
         inflater = ( LayoutInflater )context.
                 getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }
    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return result.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return position;
    }

    public class Holder
    {
        TextView tv;
        ImageView img;
    }
    @Override
    public View getView(final int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        Holder holder=new Holder();
        View rowView;       
             rowView = inflater.inflate(R.layout.program_list, null);
             holder.tv=(TextView) rowView.findViewById(R.id.textView1);
             holder.img=(ImageView) rowView.findViewById(R.id.imageView1);       
         holder.tv.setText(result[position]);
         holder.img.setImageResource(imageId[position]);         
         rowView.setOnClickListener(new OnClickListener() {            
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(context, "You Clicked "+result[position], Toast.LENGTH_LONG).show();
            }
        });   
        return rowView;

Bardziej kompaktowy przykład niestandardowego adaptera (używającego tablicy list jako moich danych):

class MyAdapter extends ArrayAdapter<Object> {
    public ArrayAdapter(Context context, List<MyObject> objectList) {
        super(context, R.layout.my_list_item, R.id.textViewTitle, objectList.toArray());
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View row = super.getView(position, convertView, parent);
        TextView title = (TextView) row.findViewById(R.id.textViewTitle);
        ImageView icon = (ImageView) row.findViewById(R.id.imageViewAccessory);
        MyObject obj = (MyObject) getItem(position);
        icon.setImageBitmap( ... );
        title.setText(obj.name);
        return row;
    }
}

I tak go używać:

List<MyObject> objectList = ...
MyAdapter adapter = new MyAdapter(this.getActivity(), objectList);
listView.setAdapter(adapter);

BaseAdapter jest najlepszym niestandardowym adapterem dla listview.

Class MyAdapter extends BaseAdapter{}

I posiada wiele funkcji, takich jak getCount(), getView() itd.

To bardzo proste.
