QUESTION
So I have an app with multiple navigation view tabs/fragments, and it is suppose to initialize the main fragment (Dashboard) when the app opens. It shows everything just fine, but when I try to access values within specific elements, such as this batteryView.getChargeLevel() method, it just points to a null object and the app crashes. I was wondering if there is anything I'm doing wrong to make it not initialize these objects?
Here is my onCreate method within my MainActivity.java:

method can only inflate views in the activity's layout which is in your case R.layout.activity_bottom_nav
.
But using the below line of code, you are trying to inflate R.id.battery
view in activity; but actually it exists in a fragment layout .ui.dashboard.DashboardFragment

QUESTION
I got the following problem. I got an extension of UIView which contains a view for displaying a value (in this case a battery value of a paired BT device). I need to have this view in several viewcontroller while the value comes from one final class (which receives and handles the device values).
Is there any way to make this UIView "static" so that the DeviceClass changes the Value in the BatteryClass and this is changed in all childs of the BatteryClass? Or is there any other way to realize this better? I just dont want to code for every viewcontroller a new method to update the BatteryView.

Answered 2017-Nov-20 at 10:48@Y.Bonafons actually has the right answer. The best way for me is here using the NotificationCenter
as I have a 1-to-N communication.
Once the battery handler registers a change in the Battery value it posts via the NotificationCenter
the new value and all registered obervers handle the changed value in their class. The only thing I haven't figured out yet if it's possible to also transmit values via the NotificationCenter
but I doubt that.
here a short example for Swift 4.0:

Install BatteryView
You can use BatteryView like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the BatteryView component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
