java - 无法转换 java.lang.Boolean 类型的对象

Question

我已经查看了本主题中的很多主题，但我无法在自己的代码中调整代码。因为显然有一个我看不到的错误。我收到了错误。

EpisodeModel.class

公共(public)课 EpisodeModel {

private String episode;

public EpisodeModel(String episode) {
    this.episode = episode;
}

public EpisodeModel()
{

}

public String getEpisode() {
    return episode;
}

public void setEpisode(String episode) {
    this.episode = episode;
}

@Override
public String toString() {
    return "EpisodeModel{" +
            "episode='" + episode + '\'' +
            '}';
}

}

MyFragment.class

public void check() {
        ref.child("Users").child(user.getUid()).child("Watched").child(seriesTitle).child("Season").child(seasonGet)
                .addChildEventListener(new ChildEventListener() {
                    @Override
                    public void onChildAdded(@NonNull DataSnapshot dataSnapshot, @Nullable String s) {

                        EpisodeModel episodeModel = dataSnapshot.getValue(EpisodeModel.class);
                        Log.i("child",episodeModel.toString());

                        Log.i("test","test2");
                        String st = dataSnapshot.getKey();
                        int no = Integer.parseInt(st);

                        if(!deneme.contains(no))
                        {
                            deneme.add(no);
                        }

                        checkModelTestAdapter.notifyDataSetChanged();
                    }

Answer 1

EpisodeModel episodeModel = dataSnapshot.getValue(EpisodeModel.class);

在这一行中，您收到错误消息，指出 Boolean 对象无法转换为 EpisodeModel。如果您将该子项的值设置为 true 或 false(不带双引号)，则可能会出现此情况。再次查看并尝试在要设置为子值的 "true" 或 "false" 两边添加双引号。
