你好,我是完全新的Android位置概念,我已經在android studio中創建了一個地圖活動。這是代碼。獲取當前位置Android API級別23

public void onMapReady(GoogleMap googleMap) { 
     mMap = googleMap; 

     mMap.setMyLocationEnabled(true); 

     Location location = null; 
     LatLng currentPosition = new LatLng(location.getLatitude(), location.getLongitude()); 
     mMap.addMarker(new MarkerOptions().position(currentPosition).title("Current Location")); 

這是正確的@Abhishek

只需添加下列行:mMap.setMyLocationEnabled(真); – nikk

您可以使用這樣

@Override 
public void onMapReady(GoogleMap map) { 
    // TODO Auto-generated method stub 
    map.setMyLocationEnabled(true); 
    LatLng currentPosition = new LatLng(location.getLatitude(),location.getLongitude()); 
    map.addMarker(new MarkerOptions().position(currentPosition).title("Current Location")); 
} 

locationonLocationChanged方法

@Override 
public void onLocationChanged(Location loc) { 
// TODO Auto-generated method stub 
location = new LatLng(loc.getLatitude(), loc.getLongitude());

}

這是給錯誤,電話需要許可? –

感謝它的工作,但問題是它是不可見的標記,你能幫我解決,如何使用標記我的位置.. –

什麼是那個位置,從哪裏得到的?你在哪裏初始化「位置」.. @Abhishek –

的谷歌地圖API的位置現在工作搞定,甚至有聽衆,你可以用它做,例如充足:

private GoogleMap.OnMyLocationChangeListener myLocationChangeListener = new GoogleMap.OnMyLocationChangeListener() { 
    @Override 
    public void onMyLocationChange(Location location) { 
     LatLng loc = new LatLng(location.getLatitude(), location.getLongitude()); 
     mMarker = mMap.addMarker(new MarkerOptions().position(loc)); 
     if(mMap != null){ 
      mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(loc, 16.0f)); 
     } 
    } 
}; 

,然後設置地圖監聽器:

mMap.setOnMyLocationChangeListener(myLocationChangeListener);
