如何在附近100米半径范围内显示地点？ [英] How to show places only in 100 meter radius nearby user ?

问题描述

获取位置的代码

  public   void  getMyLocation（活动活动）{
  int  requestPermissionsCode =  50 < /跨度>; 
 LocationManager locationManager =（LocationManager）activity.getSystemService（Context.LOCATION_SERVICE）; 
  if （ActivityCompat.checkSelfPermission（activity，Manifest.permission.ACCESS_FINE_LOCATION）！= PackageManager.PERMISSION_GRANTED&& ActivityCompat.checkSelfPermission（activity，Manifest.permission .ACCESS_COARSE_LOCATION）！= PackageManager.PERMISSION_GRANTED）{
 ActivityCompat.requestPermissions（activity， new   String  [] {Manifest.permission.ACCESS_FINE_LOCATION}，requestPermissionsCode）; 
  return ; 
} 
位置location = locationManager.getLastKnownLocation（LocationManager.GPS_PROVIDER）; 
  if （location！=  null ）{
 LatLng latLng =  new  LatLng（location.getLatitude（），location.getLongitude（））; 
  if （locationListener！=  null ）
 locationListener.onLocationFound（latLng）; 
  return ; 
} 
 
 
 locationManager.requestSingleUpdate（LocationManager.GPS_PROVIDER， new  SingleUpdateListener（），空）; 
 
 
} 

代码为LAT& LNG

  public 地址getLocationFromLatLng（上下文上下文，LatLng latLng）{ 
 android.location.Geocoder geoCoder =  new  Geocoder（context，Locale.getDefault（））; 
 
 尝试 {
  return  geoCoder.getFromLocation（latLng.latitude ，latLng.longitude， 1 ）。 get （ 0 < /跨度>）; 
}  catch （IOException e）{
  return  空; 
} 
 
} 

但问题是

什么时候我会得到替身&我将如何展示距离该附近仅100米半径的地方。 lng用户？

我尝试过：



我试图只显示附近100米的地方，但它也显示不同的街道位置，也不在那个半径

Code for get Location

public void getMyLocation(Activity activity) {
    int requestPermissionsCode = 50;
    LocationManager locationManager = (LocationManager) activity.getSystemService(Context.LOCATION_SERVICE);
    if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
        ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.ACCESS_FINE_LOCATION}, requestPermissionsCode);
        return;
    }
    Location location = locationManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);
    if (location != null) {
        LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
        if (locationListener != null)
            locationListener.onLocationFound(latLng);
        return;
    }


    locationManager.requestSingleUpdate(LocationManager.GPS_PROVIDER, new SingleUpdateListener(), null);


}

CODE FOR LAT & LNG

 public Address getLocationFromLatLng(Context context, LatLng latLng) {
    android.location.Geocoder geoCoder = new Geocoder(context, Locale.getDefault());

    try {
        return geoCoder.getFromLocation(latLng.latitude, latLng.longitude, 1).get(0);
    } catch (IOException e) {
        return null;
    }

}

But the problem is

Quote:

when i will get latitute & longitute .. how i will show only 100 meter radius places that is nearby that lat & lng of user ?

What I have tried:

I tried to show only 100 meter nearby places but it also showing different street places that not also in that radius
