【问题描述】：

realm 数据库使用 findfirst() 方法将数据发送到 mBundle.putSerializable("data", (Serializable) item);项目数据值能够接收下一个活动它的显示 java.lang.RuntimeException: Parcelable 遇到 IOException 写入可序列化对象 (name = io.realm.StationAndLocationModelRealmProxy)

您需要使您的对象可打包，而不是可序列化。

public class Channel extends RealmObject implements Parcelable {

    private String channelName;
    private String channelUrl;
    private String channelImg;
    private String channelGroup;

    public Channel() {
    }

    public String getChannelName() {
        return channelName;
    }

    public void setChannelName(String channelName) {
        this.channelName = channelName;
    }

    public String getChannelUrl() {
        return channelUrl;
    }

    public void setChannelUrl(String channelUrl) {
        this.channelUrl = channelUrl;
    }

    public String getChannelImg() {
        return channelImg;
    }

    public void setChannelImg(String channelImg) {
        this.channelImg = channelImg;
    }

    public String getChannelGroup() {
        return channelGroup;
    }

    public void setChannelGroup(String channelGroup) {
        this.channelGroup = channelGroup;
    }

    @NonNull
    @Override
    public String toString() {
        return "Channel{" +
                ", channelName='" + channelName + '\'' +
                ", channelUrl='" + channelUrl + '\'' +
                ", channelImg='" + channelImg + '\'' +
                ", channelGroup='" + channelGroup + '\'' +
                '}';
    }

    public Channel(Parcel in) {
        String[] data = new String[4];
        in.readStringArray(data);
        this.channelName = data[0];
        this.channelUrl = data[1];
        this.channelImg = data[2];
        this.channelGroup = data[3];
    }

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel parcel, int i) {
        parcel.writeStringArray(new String[]{this.channelName, this.channelUrl, this.channelImg, this.channelGroup});
    }

    public static final Parcelable.Creator CREATOR = new Parcelable.Creator<Channel>() {
        public Channel createFromParcel(Parcel in) {
            return new Channel(in);
        }

        @Override
        public Channel[] newArray(int i) {
            return new Channel[i];
        }
    };
}

这里使用 putSerializable 方法发送 Bundle 数据 - mBundle.putSerializable("data", (Serializable) item); 意图无法将数据传递给下一个活动显示logcat 标题警告
是的，它给出这个是正常的，因为领域对象需要是可打包的，而不是可序列化的。 Parcelable 首先使领域对象类像上面那样可打包，然后您可以在有意移动对象的同时执行此链接中的操作。
