如何预填充 Android Room 数据库并设置视图以显示数据？

Question

I need to setup a Room database that draws from preset information. The data will be displayed in the same format with an example photo for each and every time a new search is submitted the new data will replace the old. Below is an example of what I am trying to accomplish.

Answer 1

Here is an example of these new features which Room 2.2.0 supports.

1) Store the .db file in your assets folder and which is prepopulated using some online tool

2) then just load it using below code

Room.databaseBuilder(appContext, AppDatabase.class, "Sample.db")
.createFromAsset("database/myapp.db")
.build()

3) Create models or entities and other database set up to handle this data when you query on them
