Android onRequestPermissionsResult 未在片段中調用

Question

我正在使用谷歌地圖，所以我需要詢問一些permissions 。
我在Fragment的onStart()期間請求用戶
我正在調用requestPermissions是因為我在一個片段中，並且我也按照本答案中的建議以及您在下面的代碼中看到的那樣調用了super.onRequestPermissionsResult 。
我已經放置了一些breakpoint和Log以 100% 確定onRequestPermissionsResult沒有被調用。

class FindLessonFragment : BaseFragment(), OnMapReadyCallback, OnClusterItemClickListener<ClusterLesson>, OnClusterClickListener<ClusterLesson> {

    override fun onStart() {
        super.onStart()
    checkPermissions()
    }

    private fun checkPermissions() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            if (activity!!.checkSelfPermission(Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED
                    || activity!!.checkSelfPermission(permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                    || activity!!.checkSelfPermission(permission.READ_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED) {
                val builder = AlertDialog.Builder(activity!!)
                builder.setTitle("This app needs location access")
                builder.setMessage("Please grant location access so this app can work normally.")
                builder.setPositiveButton(android.R.string.ok, null)
                builder.setOnDismissListener {
                    requestPermissions(
                            arrayOf(permission.ACCESS_COARSE_LOCATION, permission.READ_EXTERNAL_STORAGE, permission.ACCESS_FINE_LOCATION),
                            PERMISSION_REQUEST_LOCATION)
                }
                builder.show()
            }
        }
    }

    override fun onRequestPermissionsResult(requestCode: Int, @NonNull permissions: Array<String>, @NonNull grantResults: IntArray) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)
        Log.e("PERMISSIONRESULT", "PASS PERMISSION RESULT")
        when (requestCode) {
            BaseActivity.PERMISSION_REQUEST_LOCATION -> {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    Log.d("BaseActivity", "coarse location permission granted")
                    onMapReady(mMap)
                } else {
                    val builder = AlertDialog.Builder(context!!)
                    builder.setTitle("Functionality limited")
                    builder.setMessage(
                            "Since location access has not been granted, this app will not be able to work correctly.")
                    builder.setPositiveButton(android.R.string.ok, null)
                    builder.setOnDismissListener { dialog -> dialog.dismiss() }
                    builder.show()
                }
            }
        }
    }

    companion object {

        fun create() = FindLessonFragment()

        internal const val PERMISSION_REQUEST_LOCATION = 1
    }

}

minSdkVersion 23

歡迎任何形式的幫助

該onRequestPermissionsResult必須抓在activty 。
