ForYouFragment 片段不更新

Question

嗨，我在应用程序启动时对我的 forYou 片段进行了权限检查，并且您授予权限，它会进行 api 呼叫并为您获取当前位置的天气问题是我必须切换片段以获取呼叫并再次切换以显示它在reclyerview中的问题是当我授予它不执行api的位置的权限之后，我必须刷新片段

    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

创建一个这样的方法。

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()
        }
    }
}

然后从这里

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，覆盖片段中的onRequestPermissionsResult 。 并检查权限是否授予调用getLocation() 。

在此处输入图像描述它说，并且您在 requestpermisson 行上编写没有 ActivityCompat 的代码它不起作用
