如何在打开Google地图时重定向我当前的位置

这是我在SetUpMap（）

中的代码

@Override
    public View getView(int position, View convertView, ViewGroup parent) {

        if (convertView == null) {
            convertView = LayoutInflater.from(getApplicationContext())
                    .inflate(R.layout.rating_list, parent, false);
        }
        System.out.println("list size*******"+list.size());


        HashMap<String, String> a = list.get(position);
        System.out.println("Position of hash map----->"+position);
        String name = a.get("provider_name");
        System.out.println("name--------->"+name);
        TextView tv = (TextView) convertView.findViewById(R.id.textView1);
        tv.setText(name);   
        ratingbar = (RatingBar)convertView.findViewById(R.id.vendor_rating);
        ratingbar.setOnRatingBarChangeListener(new OnRatingBarChangeListener() {

            @Override
            public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
                // TODO Auto-generated method stub
                Toast.makeText(getApplicationContext(), "Rating-->"+rating+"Position-->"+lv.getPositionForView(ratingBar), Toast.LENGTH_LONG).show();
                System.out.println("Rating------>"+rating+"position----->"+lv.getPositionForView(ratingBar));
            }
        });

        return convertView;

还有我如何更改标记？我只在我的位置得到那个蓝色圆圈。我想把它改成Pin

<project name="NuggetaGameServer" basedir="." default="jar">
<target name="jar" description="jar">
    <delete file="lib/myServer.jar" />

    <mkdir dir="classes" />
    <echo message="Compiling the java source files..." />
    <javac destdir="classes" debug="on" failonerror="yes" includeantruntime="false">
        <src path="src" />
    </javac>

    <jar destfile="lib/myServer.jar">
        <zipfileset dir="classes/" />
    </jar>
</target>

在Map准备就绪后立即获取用户的当前位置，您需要像这样设置相机的动画

Location location = this.mGoogleMap.getMyLocation();

    if (location != null) {

        LatLng target = new LatLng(location.getLatitude(), location.getLongitude());
        CameraPosition position = this.mGoogleMap.getCameraPosition();

        Builder builder = new CameraPosition.Builder();
        builder.zoom(15);
        builder.target(target);

        this.mGoogleMap.animateCamera(CameraUpdateFactory.newCameraPosition(builder.build()));

      }

因此，getMyLocation()必须获取用户的位置。使用可以使用PROVIDERS来获取位置。您还可以使用LocationListener使用GoogleApiClient收听位置信息。在发布此处之前，请阅读Getting the Last Known Location和Receiving Location Updates的文档。

要为您的位置提供自定义标记，可以使用名为addMarker

的内容

mGoogleMap.addMarker(new MarkerOptions()
                      .position(new LatLng(location.getLatitude(), location.getLogitude()))
                      .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));

您可以尝试使用此代码，我们可以通过NETWORK_PROVIDER获取谷歌地图中的位置。 NETWORK_PROVIDER从您的WIFI位置或您的网络提供商公司（IDEA，AIRTEL，VODAPHONE）中选择您的位置。

try {
                    if (googleMap == null) {
                        googleMap = ((MapFragment) getFragmentManager()
                                .findFragmentById(R.id.map)).getMap();
                    }
                    googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
                    googleMap.setMyLocationEnabled(true);
                    LocationManager location_manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
                    LocationListener listner = new getlatlngListner();
                    location_manager.requestLocationUpdates(
                            LocationManager.NETWORK_PROVIDER, 2000, 2000, listner);
                    location_manager
                            .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                } catch (Exception e) {
                    e.printStackTrace();
                }

private MarkerOptions mMarkerOptions = new MarkerOptions();
mMarkerOptions.visible(true);
mMarkerOptions.icon(BitmapDescriptorFactory.fromBitmap(Your bitmap));
mMap.setMyLocationEnabled(true);
mMap.getUiSettings().setMyLocationButtonEnabled(false);
mMap.setOnMyLocationChangeListener(new GoogleMap.OnMyLocationChangeListener() {
                    @Override
                    public void onMyLocationChange(Location location) {
                        LatLng mPos = new LatLng(location.getLatitude(),location.getLongitude());
                        mMarkerOptions.position(mPos);
                        mMap.addMarker(mMarkerOptions);
                        mMap.moveCamera(CameraUpdateFactory.newLatLng(mPos));
                        mMap.animateCamera(CameraUpdateFactory.zoomTo(17));

                    }
                });
