ForYouFragment 片段不更新

Question

嗨，我在應用程序啟動時對我的 forYou 片段進行了權限檢查，並且您授予權限，它會進行 api 呼叫並為您獲取當前位置的天氣問題是我必須切換片段以獲取呼叫並再次切換以顯示它在reclyerview中的問題是當我授予它不執行api的位置的權限之后，我必須刷新片段

    fusedLocationClient.lastLocation.addOnSuccessListener(requireActivity()) { location ->
        if (location != null) {
            currentLocation = location
            val currentLatLng = LatLng(location.latitude, location.longitude)
            val currentAddress = getAddress(location.latitude, location.longitude)
            Log.d("TAG", "klagenfurt : ${currentAddress}")
            retrofitOneCallResponse(location.latitude, location.longitude, currentAddress)
            dataService.getFavorites(this)

        }


    }
    if (ActivityCompat.checkSelfPermission(
            requireContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
    {
        ActivityCompat.requestPermissions(
            requireActivity(),
            arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION),
            MapViewFragment.LOCATION_PERMISSION_REQUEST_CODE
        )

        return
    }

Answer 1

創建一個這樣的方法。

private fun getLocation(){
fusedLocationClient.lastLocation.addOnSuccessListener(requireActivity()) { location ->
        if (location != null) {
            currentLocation = location
            val currentLatLng = LatLng(location.latitude, location.longitude)
            val currentAddress = getAddress(location.latitude, location.longitude)
            Log.d("TAG", "klagenfurt : ${currentAddress}")
            retrofitOneCallResponse(location.latitude, location.longitude, currentAddress)
            dataService.getFavorites(this)
        }else{
         getLocation()
        }
    }
}

然后從這里

if (ActivityCompat.checkSelfPermission(
            requireContext(), android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED)
    {
        requestPermissions(
            arrayOf(android.Manifest.permission.ACCESS_FINE_LOCATION),
            MapViewFragment.LOCATION_PERMISSION_REQUEST_CODE
        )
    }else{
      getLocation()
}


override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray): Unit {
      if(requestCode==MapViewFragment.LOCATION_PERMISSION_REQUEST_CODE){
          if(grantResults[0]==PackageManager.PERMISSION_GRANTED){
              getLocation();
          }
      }
}

此外，覆蓋片段中的onRequestPermissionsResult 。 並檢查權限是否授予調用getLocation() 。

在此處輸入圖像描述它說，並且您在 requestpermisson 行上編寫沒有 ActivityCompat 的代碼它不起作用
