我有一个应用程序,用户可以通过点击ImageView并设置图像或通过从相机拍摄新照片来添加图像。我想将设置的图像存储到SQLite数据库中。

公共void insertAddKeyEvent(byte[] childpic,String eventDate,String eventDetails)
此方法用于将子图像、事件日期和事件详细信息插入到数据库中。
{
ContentValues addkeyValues=new ContentValues();
addkeyValues.put("CHILDPICS",childpic);
addkeyValues.put("EVENTDATE", eventDate);
addkeyValues.put("EVENTDETAILS", eventDetails);
parentmaster.insert("ADDKEYEVENT",null,addkeyValues);
