Well… I don’t know where to start with this… I’m doing a course where the teacher has not taught us anything about databases and now he want us to do an app with kotlin and sqlite where we make an Activity with a button "New table" where user can create a database table with a name and dynamic fields. I’ve been searching all day about it and I got nothing.

I thought about create a CRUD but I’m with the trouble that I don’t know how to make any of this dynamically.

For now I have this SQLiteHelper that I saw it was necessary to make and I put const values to test it because I don’t have any clue how to pass the values from the user view.

class AdminSQLiteOpenHelper(context: Context, name: String, factory: CursorFactory?, version: Int) : SQLiteOpenHelper(context, name, factory, version) {

    companion object{
        const val DATABASE_NAME = "test.db"
        var TABLE_NAME = "Testing_Table"
        const val COL_1 = "ID"
        var COL_2 = "NAME"
        var COL_3 = "SURNAME"
        var COL_4 = "YEARS"
    }
    override fun onCreate(db: SQLiteDatabase) {
        db.execSQL("create table TABLE_NAME(COL_1 primary key autoincrement, COL_2 text, COL_3 text, COL_4 int)")
    }

    override fun onUpgrade(db: SQLiteDatabase, oldVersion: Int, newVersion: Int) {
        db.execSQL("drop table if exists TABLE_NAME")
        onCreate(db)
    }
}

And I have this activity

class MainActivity2Crear : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main_activity2_crear)


        val buttonCrear = findViewById<Button>(R.id.buttonCrear)
        buttonCrear.setOnClickListener{
            val register = ContentValues()
            register.put(COL_1, textView.getText().toString())
            TABLE_NAME = register.toString()
            val admin = AdminSQLiteOpenHelper(this, TABLE_NAME, null, 1)
            val bd = admin.writableDatabase
            bd.insert(TABLE_NAME, null, register)
            bd.close()
            textView.setText("")
            Toast.makeText(this, "Table created", Toast.LENGTH_SHORT).show()
            val intent = Intent(this, MainActivity2::class.java)
            startActivity(intent)
        }

        val button = findViewById<Button>(R.id.button)
        button.setOnClickListener{
            val intent = Intent(this, MainActivity2::class.java)
            startActivity(intent)
        }
    }
}

I just did create button for now because I don’t know what I’m doing…
I know probably this question will have downvotes but I just want some help or a tutorial or something that help me to understand how to make this exercise…
