相机并在SQL数据库中保存图像

Question

我想打开相机onclick。它工作正常。现在拍照后我不想在画廊中保存那张照片。我想在sql数据库中保存该图片

Answer 1

要在数据库中插入图像，请编写以下代码：

public class CameraHandler implements PictureCallback {
.....
 @Override
 public void onPictureTaken(byte[] data, Camera camera) {
       insertImageInDB(data);
}

public void insertImageInDB(byte[] theImageBytes){
    SQLiteDatabase db               =   dbHelper.getWritableDatabase();

    String sql                      =   "INSERT INTO MY_IMAGES (image_id,other_data,the_image) VALUES(?,?,?)";
    SQLiteStatement insertStmt      =   db.compileStatement(sql);
    insertStmt.bindString(1, id);
    insertStmt.bindString(2,otherData);
    insertStmt.bindBlob(3, theImageBytes);
    insertStmt.executeInsert();
    db.close();
}

}
