將Realm變量從其他類傳遞到適配器中的getView

Question

在我的主要活動中，我喜歡將結果值從另一個類傳遞到適配器中的getview。

我可以將變量radioPosition傳遞給適配器，但不能在getView（）中使用它；

我的問題是如何將我的Setting類中的領域變量傳遞給School適配器中的getview（）

主要活動

public class MainActivity extends AppCompatActivity {

    ....
    Setting setting = realm.where(Setting.class).findFirst();
    //radioPosition is from Setting Class
    Integer radioPosition = setting.getPosition();
    RealmResults<School> schools = realm.where(School.class).findAll();
    //schools is from School Class

    final SchoolAdapter adapter = new SchoolAdapter(this, R.id.schools_list, schools, Integer radioPosition, true);
    ....
}

學校適配器：

public class SchoolAdapter extends RealmBaseAdapter<School> implements ListAdapter {

    ....
    public SchoolAdapter(Context context, int resId, RealmResults<School> realmResults,  Integer radioPosition, boolean automaticUpdate) {

        super(context, realmResults,  automaticUpdate);

    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;
        if (convertView == null) {
            convertView = inflater.inflate(android.R.layout.simple_list_item_1, parent, false);
            viewHolder = new ViewHolder();
            viewHolder.school = (TextView) convertView.findViewById(android.R.id.text1);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

    .....

Answer 1

  private int mRadioPosition;

  public SchoolAdapter(Context context, int resId, RealmResults<School> realmResults,  Integer radioPosition, boolean automaticUpdate) {

        super(context, realmResults,  automaticUpdate);
        mRadioPosition = radioPosition;
    }

在getView方法中使用mRadioPosition 。 如果我誤解了您的問題，請告訴我。
