上传图像并将其保存到房间持久性库中

Question

我正在尝试使用Android中的房间持久性库构建一个记事应用程序。

当我想保存带有标题，描述和时间戳的新便笺时，它是可行的，但是我需要从图库中上传图像，并将带有标题，描述和时间戳的图像另存为新便笺。

有人可以帮助我吗？这是我尝试过的：

@Entity(tableName = "notes")
public class Note implements Parcelable
{ 
    @PrimaryKey(autoGenerate = true)
    private int id;
    @ColumnInfo(name = "title")
    private String title;
    @ColumnInfo(name = "content")
    private String content;
    @ColumnInfo(name = "timestamp")
    private String timestamp;

    @Ignore
    public Note()
    {
    }

    public Note(int id, String title, String content, String timestamp)
    {
        this.id = id;
        this.title = title;
        this.content = content;
        this.timestamp = timestamp;
    }

    protected Note(Parcel in)
    {
        id = in.readInt();
        title = in.readString();
        content = in.readString();
        timestamp = in.readString();
    }

    public static final Creator<Note> CREATOR = new Creator<Note>() 
    {
        @Override
        public Note createFromParcel(Parcel in)
        {
            return new Note(in);
        }

        @Override
        public Note[] newArray(int size)
        {
            return new Note[size];
        }
    };

    public int getId()
    {
        return id;
    }

    public void setId(int id)
    {
        this.id = id;
    }

    public String getTitle()
    {
        return title;
    }

    public void setTitle(String title)
    {
        this.title = title;
    }

    public String getContent() {
        return content;
    }

    public void setContent(String content) {
        this.content = content;
    }

    public String getTimestamp()
    {
        return timestamp;
    }

    public void setTimestamp(String timestamp)
    {
        this.timestamp = timestamp;
    }

    @Override
    public String toString()
    {
        return "Note{" +
                "id=" + id +
                ", title='" + title + '\'' +
                ", content='" + content + '\'' +
                ", timestamp='" + timestamp + '\'' +
                '}';
    }

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

    @Override
    public void writeToParcel(Parcel dest, int flags)
    {
         dest.writeInt(id);
         dest.writeString(title);
         dest.writeString(content);
         dest.writeString(timestamp);
    }
}
