私はレイアウトインフレータのロジックを理解することができません adapetrクラスのレイアウトインフレータの使用は何ですか?公式ドキュメントによるとレイアウトインフレータとは何ですか?
public class WordAdapter extends ArrayAdapter<Word> {
public WordAdapter(Activity context, ArrayList<Word> words) {
// Here, we initialize the ArrayAdapter's internal storage for the context and the list.
// the second argument is used when the ArrayAdapter is populating a single TextView.
// Because this is a custom adapter for two TextViews and an ImageView, the adapter is not
// going to use this second argument, so it can be any value. Here, we used 0.
super(context, 0, words);
}
@NonNull
@Override
public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
// Check if the existing view is being reused, otherwise inflate the view
View listItemView = convertView;
if (listItemView == null) {
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.list_item, parent, false);
}
