我想将图像存储在sqlite数据库中，该数据库取自gallery和camera android

我有一个应用程序，用户可以通过单击Imageview并设置图像以及从相机拍摄新照片来添加图像。我想将该设置图像存储到sqlite数据库中。

    }

database.java

public void insertAddKeyEvent（字节[]childpic，字符串eventDate，字符串eventDetails）

通过以下方式将

位图

转换为

字节[]

ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 100, baos);
byte[] imageData = baos.toByteArray();

---

并添加

字节[]

进入数据库中的

BLOB

字段。

在SQLite中将图像设置为BLOB，或者只是链接到存储中的img？我正在寻找代码bro我搜索了代码bt没有得到它，所以请你给我提些建议。我已经为数据库以及打开相机和画廊做了编码。我已经共享了我的编码，所以请确实建议我.After

ivChildPics.setImageBitmap（bmp）

对于gallery，我应该做同样的事情吗？是的，如果您可以在

图像视图中看到图像，图像将以何种形式存储在数据库中？它是图像路径吗？否，它将存储为
BLOB
如果要检索它，您必须在
byte[]中获取它。
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bitmap.compress(CompressFormat.JPEG, 100, baos);
byte[] imageData = baos.toByteArray();
