• Updating a Single Column In Room Database

  That's the function I'm using for updat

  private fun updateSettingsDatabase(settingsDao: SettingsDao) {
          lifecycleScope.launch {
              settingsDao.update(SettingsEntity(
                  1,
                  nightMode=nightModeResult,
              ))
          }
  }
  
  @Query("SELECT * FROM `settings-table`")
  fun fetchCurrentSettings(): Flow<List<SettingsEntity>>
  

  I specified nightMode= because I thought that this way I'm only updating this colummn, but it turns out that it resets every column, how do I update a single column, while keeping the values the rest of the columns?
• Using EdittextPreference for Goto search

  sorry for my poor English. I want to use EditTextPreference in my bottom nav like the pic below, ![screenshot][1]

  I have recycleview xml in my project with in many sub cardview layouts(which is scrollable) and I want to create item in the bottom nav which is called "Goto". When the "Goto" item is clicked i want it to pop-up like the screenshot. And when user enters a number(according to the cardviews i.e if the number of cardview is 40 user must enter 1-40) I want to search the cardview by its ID. Thank you and I hope u got it, If u have any questions let me know [1]: https://i.stack.imgur.com/grK8P.jpg

  My xml format look like this. As you see in the blow since the cardviews are huge in number it is not cool to scroll all the way down that is why i need Goto item in the bottom nav to search it by its ID when the user click number in the EditTextPreference as u see in the screenshot. i.e The screenshot is not from my app

  I see that no file is saved even though I specify a file pathname log.log in the logs tab (Run/Debug configurations of Pycharm)
• Validate user input with data in .txt file

  I have searched and searched and tried everything. I am creating a game where the user will input a pre-assigned pin and I want to validate that pin against a .txt file in Python. I have tried so many different lines of code and my result is either everything is valid or nothing is valid. What am I doing wrong? The pins are formatted on each line and are alpha numeric like this...

  Here is what I have:

  user_input = input('Please enter your PIN: ')
  if user_input in open("PINs.txt").read():
      print('Congratulations!  Click the button below to get your Bingo Number.')
  else:
      print('The PIN you entered does not match our records.  Please check your PIN and try again.')
  
• Kotlin Coroutines Unit Testing

  Im trying to test this suspend function:

  suspend fun <T> getResult(call: suspend () -> Response<T>): Resource<T> {

    val body = response.body()
    val code = response.code()
  
    if (response.isSuccessful) {
  
      Log.d(Cybrid.instance.tag, "Data: ${response.code()} - ${response.body()}")
      return Resource.success(body!!, code)
  
    } else if (response.code() == HTTP_UNAUTHORIZED || response.code() == HTTP_FORBIDDEN) {

        cybrid.listener.let {
          cybrid.invalidToken = true
          it?.onTokenExpired()
        }
      }
      Log.e(Cybrid.instance.tag, "Error - Something wrong with TOKEN : ${response.code()} ${response.message()}")

      return Resource.error(message = response.message(), data= response.body(), code= response.code())
    }
  }
  

  With this Unit Test Case, all it cover except line 13 , I dont know how to cover the line!!!

  @ExperimentalCoroutinesApi
  @Test
  fun get400ErrorServerTest() = runBlocking {
  
      Cybrid.instance.setBearer("Bearer")
      val pricesService = AppModule.getClient().createService(PricesApi::class.java)
      val result = getResult { pricesService.listPrices() }
  
      Assert.assertNotNull(result)
      Assert.assertEquals(result.code, 400)
      Assert.assertNull(result.data)
  }
  

  The coverage report says:

  

  Some idea to get coverage for line 13 ??? Thnanks
• Android ZoneDateTime.withHour always sets hour to 8

  So I am tring to schedule alarm at a particular time on current day using AlarmManager. To do that I am using ZoneDateTime to get current time and then updating it to the hour at which I need to set the alarm. But for some reason time.withHour is giving me 8pm or 8am no matter what hour I am passing to it. Am I doing something wrong here?

  var time = ZonedDateTime.now()    //getting current time at my timezone
  time = time.withHour(22).withMinute(8).withSecond(0)
  print(time)                       //getting 8am/8pm at my timezone
  val timeMilis = time.toInstant().toEpochMilli()

• Python Tkinter - Text widget runnig function before inserting key

  I'm trying to execute function after pressing key. Problem is if I use this code:

  text = tk.Text(root)
  text.bind("<KeyPress>", lambda event:print(text.get(1.0, tk.END)))
  text.pack()
  

  When I press first key, nothing is printed. It executes my functions before inserting character, how I can avoid that ? Whitout using <KeyRelease> Thanks!
