QUESTION
I'm working on a project to select some options according to the picture showing on the side. These options are about size, colors...
Basically, I'm trying to show the picture on a lightbox (which is working fine), but I'm trying to put next to the picture a white background with a form with some options and action buttons. When I try to do it, it actually doesn't work as it should.
I'm using this function

I am working on the program below. How do you calculate totalCostPerMiles = (numMiles / milesPerGallon) * price;
when totalCostPerMiles
is a int
, numMiles
and milesPerGallon
are doubles
, and price
is a int
to get the calculated value?
Suppose milesPerGallon = 30;
, numMiles = 15;
, and price = 400;
.
I need numMiles / milesPerGallon
to output 0.5 instead of 0 and totalCostPerMiles
to output 200 instead of 0.
All variables storing measured values must be doubles and all variables storing monetary values must be integers.

Answered 2020-Sep-25 at 00:29math ops are always binary (so, 2 arguments. 'a+b+c' is not a 3-way addition; it's shorthand for (a+b)+c
- 2 nested binary operations.
If either 'side' of the binary operation is a double, then first the other number (int, long, float, byte, char, short, doesn't matter) is converted to a double, then the operation is done, and the result is a double.
So, (numMiles / milesPerGallon)
is an expression of type double.
Then, you do that (so, a double), times an int: that * price
. price is an int, but double*int
is done by first converting that int to a double. Thus, the entire result is, itself, a double.
You then try to assign that to an int, and that's where the problem occurs: You can't do that, because java has no idea what you want. Should 6.5
become 6, or 7? What about 1.239e123
?
You can choose what to do. The simplest way is the 'lop off rounding' mode, which lops off the fraction (so, round down.. unless the number is negative, in which case that'd round up):
QUESTION
I have a two CoreData objects:
RoadTrip
StatePlate
.
Each RoadTrip
items holds an NSSet
of StatePlate
.
Screen 1 (TripList
) shows a list of all RoadTrip
items. Screen 2 (StateList
) shows a list of all StatePlate
items in associated with the RoadTrip
that a user selects. Selecting a StatePlate
item in Screen 2 will toggle a bool value associated with that item.
Even though I can show the data and can toggle the bool value of each StatePlate
, I am not seeing an immediate change to the UI of the screen. The StatePlate
should jump from Section to Section in Screen 2 when it's bool value is toggled.
How can I pass this FetchedObject correctly from Screen 1 to Screen 2 so the UI is binded with the data?
Screen 1 (TripList
)
ANSWER
Answered 2020-Jul-28 at 04:28Your trip
as object is not changed when plate
has changed, so even if it was observed UI was not refreshed.
Here is possible force-refresh approach.
QUESTION
I am implementing a Google Map into my application which includes setting the current location of the user. I have added the ACCESS_FINE_LOCATION into the application manifest and my gradle file uses a minimum SDK of 23. The device emulator that I am running is also 23.
My understanding is that with version 23 I do not need to ask for permission, as that is handled with the app installation or upgrade.
The application is crashing saying that I need to allow location access (see attached logcat entry). It is on the statement (line 64) on the attached MapsActivity.java
...ANSWER
Answered 2020-Mar-18 at 12:37As per Android Document:
Android 6.0 Marshmallow introduced a new permissions model that lets apps request permissions from the user at runtime, rather than prior to installation. Apps that support the new model request permissions when the app actually requires the services or data protected by the services. While this doesn't (necessarily) change overall app behavior, it does create a few changes relevant to the way sensitive user data is handled:
For SDK version 23, you need to ask run time permission to access the device location. For that, please call enableMyLocation()
method in onCreate()

QUESTION
Hello I am new to RShiny, and I'm trying to build an application for a project.
I have 5 images in my UserInterface I would like to make them clickable : When you click on image, it displays a subset of the dataframe in the mainPanel.
My Dataframe contains a column called "Mood",and there are 5 moods ("Party and Dance", "Rap","Happy vibes" , "Sunday Chillout" and "Roadtrip music"). Each image should display rows of one of the moods.
This is the code I have used for now :
UI.R
...ANSWER
Answered 2020-Feb-25 at 07:43It has been a while since I used Shiny so I may be a bit rusty. But here is a possible approach to tackling your issue: You could use a reactiveValue
to keep track of which mood is selected, and update that variable whenever one of the images is clicked. Then use that reactiveValue
in subsetting your dataframe
, as shown below. Hope this helps!
