SugarORM:SugarRecord.count返回4，但是SugarRecord.listAll返回空列表 [英] SugarORM: SugarRecord.count returns 4 but SugarRecord.listAll returns empty list

问题描述

我在模型中使用@Table批注，并在DialogFragment.setPositiveButton.onClick

I use the @Table annotation for my model and call SugarRecord.save in a DialogFragment.setPositiveButton.onClick

在具有ListView的片段中，我想通过SugarRecord.listAll加载所有条目，但是尽管SugarRecord.count返回正确的计数，但它返回一个空列表.

In the Fragment with the ListView I wanted to load all entries via SugarRecord.listAll but it returns an empty list, although SugarRecord.count returns the proper count.

@Table
@ToString
@Getter
public class Syllable {

    private Long id;

    @Unique
    String characters;
    @Setter
    boolean active = true;

    public Syllable(String characters) {
        this.characters = characters;
    }
}

DialogFragment.setPositiveButton

.setPositiveButton(R.string.save, new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        SugarRecord.save(new Syllable(charactersET.getText().toString()));
                        syllableDialogListener.onSyllableSave();
                    }
                })

Fragment.onSyllableSave

private void updateSyllables() {
        long count = SugarRecord.count(Syllable.class); // returns 4 (e.g.)
        List<Syllable> syllables = SugarRecord.listAll(Syllable.class); // returns empty list
    }

推荐答案

好，我只是在模型上缺少一个空的构造函数> _>问题是这不是在android中真正打印为红色错误样式的错误工作室，所以我只是想念这个; D

OK, I was just missing an empty constructor at the model >_> Problem was this wasn't really printed as an red-error-style error in android studio so I just missed this ;D
