getSystemServices is undefined when called in a Fragment?

Question

I want TextViews to display the sensors readings in a Fragment. When trying to initialize the SensorManager the getSystemService

Answer 1

sensorManager = (SensorManager) 
requireActivity().getSystemService(Context.SENSOR_SERVICE);

Answer 2

Just one more method call:

sensorManager = (SensorManager) getActivity().getSystemService(Context.SENSOR_SERVICE);  

Why that one extra method call?
the getSystemService() method that provides access to system services comes from Context. An Activity extends Context, a Fragment does not. Hence, you first need to get a reference to the Activity in which the Fragment is contained and then magically retrieve the system service you want.

Answer 3

Use:

getActivity().getSystemService(name)

Answer 4

For kotlin this is what worked for me.

private fun hideKeyboard() {
        val inputManager = activity?.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
        if (inputManager.isAcceptingText) {
            inputManager.hideSoftInputFromWindow(activity?.currentFocus?.windowToken, 0)
        }
    }

Answer 5

On Kotlin use:

this.sensorManager = activity!!.getSystemService(Context.SENSOR_SERVICE) as SensorManager

Answer 6

sensorManager = (SensorManager) getActivity().getSystemService(Context.NAMEOF_SERVICE);

Fragments cannot directly call System Services , You have to use Activity with which these Fragment is Attached
