我在将 RecyclerView 集成到我的应用程序时遇到问题。
它向我抛出了这个异常

这是我创建适配器的地方
mAdapter = new FirebaseRecyclerAdapter<StreamData, StreamerViewHolder>(StreamData.class, R.layout.cv_stream, StreamerViewHolder.class, refStreamers) {
@Override
protected void populateViewHolder(StreamerViewHolder streamerViewHolder, StreamData streamData, int i) {
Log.e("TAG", String.valueOf(mAdapter.getItemCount()));
streamerViewHolder.name.setText(streamData.getInfo().getName());
streamerViewHolder.display_name.setText(streamData.getInfo().getDisplay_name());
streamerViewHolder.game.setText(streamData.getInfo().getGame());
}
};
它似乎要破坏的数据对象就是这个
public class StreamData {
private ConditionData condition;
private InfoData info;
private ImageData image;
private CustomData custom;
private String online;
public StreamData(ConditionData condition, InfoData info, ImageData image, CustomData custom, String online) {
this.condition = condition;
this.info = info;
this.image = image;
this.custom = custom;
this.online = online;
}
public StreamData() {
}
public ConditionData getCondition() {
return condition;
}
public void setCondition(ConditionData condition) {
this.condition = condition;
}
public InfoData getInfo() {
return info;
}
public void setInfo(InfoData info) {
this.info = info;
}
public ImageData getImage() {
return image;
}
public void setImage(ImageData image) {
this.image = image;
}
public CustomData getCustom() {
return custom;
}
public void setCustom(CustomData custom) {
this.custom = custom;
}
public String getOnline() {
return online;
}
public void setOnline(String online) {
this.online = online;
}
}
我听说杰克逊有问题，但我对序列化 JSON 之类的东西很陌生。如果你需要任何额外的信息问我，我会告诉你:)

添加了我的数据库对象的示例
