How To Show Current Position Marker On Map In Android?

I am developing an application in which I want to display current location using marker in my map. I am using Google Map v2. Here I can display Map and marker when GPS is off ,but

Solution 1:

Use below code it worked for me:

@OverridepublicvoidonLocationChanged(Location location) {

   map.clear();

   MarkerOptionsmp=newMarkerOptions();

   mp.position(newLatLng(location.getLatitude(), location.getLongitude()));

   mp.title("my position");

   map.addMarker(mp);

   map.animateCamera(CameraUpdateFactory.newLatLngZoom(
    newLatLng(location.getLatitude(), location.getLongitude()), 16));

  }

Solution 2:

Try this,it is showing current location:

privatevoidinitilizeMap() {
    if (googleMap == null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();
                // to set current location
        googleMap.setMyLocationEnabled(true);

        // check if map is created successfully or notif (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }

Solution 3:

Try this:-

privatevoidinitMap() {
    if (googleMap != null) {
        googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                R.id.map)).getMap();
                // to set current location
        googleMap.setMyLocationEnabled(true);
        Marker pos_Marker =  googleMap.addMarker(new MarkerOptions().position(starting).icon(BitmapDescriptorFactory.fromResource(R.drawable.ic_laumcher)).title("Starting Location").draggable(false));

        pos_Marker.showInfoWindow();
        googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(START_locationpoint, 10));
        googleMap.animateCamera(CameraUpdateFactory.zoomTo(15),2000, null);  

        // check if map is created successfully or notif (googleMap == null) {
            Toast.makeText(getApplicationContext(),
                    "Sorry! unable to create maps", Toast.LENGTH_SHORT)
                    .show();
        }
    }

Solution 4:

Use this. It works for me.

@OverridepublicvoidonLocationChanged(Location location) {
    map.clear();

    mp1 = newMarkerOptions();
    mp1.position(newLatLng(location.getLatitude(),
            location.getLongitude()));

    mp1.draggable(true);
    mp1.icon(BitmapDescriptorFactory
            .defaultMarker(BitmapDescriptorFactory.HUE_ROSE));
    map.addMarker(mp1);

    map.animateCamera(CameraUpdateFactory.newLatLngZoom(
            newLatLng(location.getLatitude(), location
                    .getLongitude()), 20));
}

You may try this:

    Marker mCurrLocationMarker;

    {
        super.onCreate(savedInstanceState);

        getSupportActionBar().setTitle("Map Location Activity");

        mapFrag = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
        mapFrag.getMapAsync(this);
    }
