java - 无法转换类型为java.lang.Boolean的对象

在本主题中，我已经看了很多主题，但是我无法在自己的代码中修改代码。因为显然有一个我看不到的错误。而且我得到了错误。

EpisodeModel.class

公共类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();
                    }

最佳答案

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


在此行中，您得到错误消息，表明布尔对象无法转换为EpisodeModel。如果您已将该子项的值设置为true或false（不带双引号），则可能会出现。再次看到它，并尝试在要设置为子值的“ true”或“ false”周围添加双引号。
