SQLite - Datebase colums

SQLite - Datebase colums - android

Can you help solve the problem with the missing column? It seems to me that I did everything right, but I get the error that something is wrong with one column.

Mates can you explain me what is wrong ? Thx

Probably you add this column but forget to add migration from old database version. You can check it by clear all application data (or delete and install it). If reinstall fix the problem you should create migration from old database verstion to new
Also you can refactor all your database to use Room instead of ugly ORMLite.
It's friendly and powerfull persistance library from google

I believe that your issue may be due to the line :-
val sqlCreateTable =
"CREATE TABLE$dbTable($colID INTEGER PRIMARY KEY, $colStezenie TEXT, $colZegar TEXT, $colData TEXT, $colPosilek TEXT, $colStres TEXT,$colSamopoczucie TEXT, $colHiperglikemia TEXT)"
There is no space between the TABLE keyword and the table name.
Try changing to :-
val sqlCreateTable =
"CREATE TABLE $dbTable($colID INTEGER PRIMARY KEY, $colStezenie TEXT, $colZegar TEXT, $colData TEXT, $colPosilek TEXT, $colStres TEXT,$colSamopoczucie TEXT, $colHiperglikemia TEXT)"
And then after uninstalling the App or deleting the App's data try rerunning.

The problem of saving data in the database and closing the program quickly after execution

I have a layout that has two EDITETEXT and they should be filled and saved in the database by pressing the save button
Everything is correct, but when I write the button code, the program runs
and quickly exits the program
(And that there is no mistake)
If I want to say complete, it means: everything is correct until I want to use the database :|

Add layout file before any action or initialization of widget.
It should be like
MainActivity : AppCompatActivity() {
//Your code
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
val buttonsave:Button = findViewById(R.id.buttonsave)
buttonsave.setOnClickListener {
//Your code
}
//Your code

Content provider: onCreate() type mismatch - Context? vs Context (Kotlin)

I am trying to implement the onCreate() method in my Content provider and can't wrap my head around what I should do to resolve this error:

Here is my DatabaseHandler.kt

I never work in android studio / kotlin and I guess it is probably a simple solution but I can't seem to fix it...

The context that you use to create databaseHandler has a nullable annotation.
public final #Nullable Context getContext() {
return mContext;
}
So you can fix it by making the databaseHandler context nullable
class DatabaseHandler(var context: Context?)
Or you can add a null check before instantiating the databaseHandler :
override fun onCreate(): Boolean {
dbHandler = context?.let { DatabaseHandler(it) }
return false
}

context returns a nullable Context (a Context?) because it's null in the lifecycle before onCreate(). According to the documentation, inside onCreate(), it is no longer null, so it is safe to assert non-null with !!.
Also, you should be returning true from onCreate if there wasn't a problem.
override fun onCreate(): Boolean {
dbHandler = DatabaseHandler(context!!)
return true
}

"too many arguments for public constructor string() defined " Kotlin problem

I'm a bit lost, make a database, where the user will have to save the results of the study, in which he will choose data from various widgets, such as spinners or RGs. How to encode variables of type Int or String is not a problem for me but in the case of Spinner number picker and RG already. Can somebody straighten me out?

The problem with node class here you have declared total 9 parameter :
