这是我在示例应用程序中实现 Google Maps的方式 ：
首先 ： 将支持库添加到eclipse中，并确保您正在构建的应用程序包含该库。
之后的实现是这样的：
public class MainActivity extends FragmentActivity implements LocationListener, OnMapClickListener, onMapLongClickListener { private static final int GPS_ERRORDIALOG_REQUEST = 9001; GoogleMap map; List<Address> matches; TextView tvLocation; String addressText; double latitude; double longitude; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); if (servicesOK()) { Toast.makeText(this, "Ready to map!!", Toast.LENGTH_LONG).show(); setContentView(R.layout.activity_main); // Getting reference to the SupportMapFragment of activity_main.xml SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager() .findFragmentById(R.id.map); // Getting GoogleMap object from the fragment map = fm.getMap(); // Enabling MyLocation Layer of Google Map map.setMyLocationEnabled(true); // Getting LocationManager object from System Service // LOCATION_SERVICE LocationManager locationManager = (LocationManager) getSystemService(LOCATION_SERVICE); // Creating a criteria object to retrieve provider Criteria criteria = new Criteria(); // Getting the name of the best provider String provider = locationManager.getBestProvider(criteria, true); // Getting Current Location Location location = locationManager.getLastKnownLocation(provider); if (location != null) { onLocationChanged(location); } locationManager.requestLocationUpdates(provider, 20000, 0, this); } else { setContentView(R.layout.activity_main); } } @Override public void onProviderDisabled(String provider) { // TODO Auto-generated method stub } @Override public void onProviderEnabled(String provider) { // TODO Auto-generated method stub } @Override public void onStatusChanged(String provider, int status, Bundle extras) { // TODO Auto-generated method stub }对于位置更改：
@Override public void onLocationChanged(Location location) { tvLocation = (TextView) findViewById(R.id.tv_location); // Getting latitude of the current location latitude = location.getLatitude(); // Getting longitude of the current location longitude = location.getLongitude(); // Creating a LatLng object for the current location LatLng latLng = new LatLng(latitude, longitude); // Showing the current location in Google Map map.moveCamera(CameraUpdateFactory.newLatLng(latLng)); // Zoom in the Google Map map.animateCamera(CameraUpdateFactory.zoomTo(15)); map.addMarker(new MarkerOptions().position( new LatLng(latitude, longitude)).title(addressText)); map.setonMarkerClickListener(new GoogleMap.onMarkerClickListener() { @Override public boolean onMarkerClick(Marker marker) { Toast.makeText(getbaseContext(), "marker clicked", Toast.LENGTH_LONG).show(); return false; } }); // TODO Auto-generated method stub Geoprer geoCoder = new Geoprer(this); try { matches = geoCoder.getFromLocation(latitude, longitude, 1); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } Address bestMatch = (matches.isEmpty() ? null : matches.get(0)); addressText = String.format("%s, %s, %s", bestMatch .getMaxAddressLineIndex() > 0 ? bestMatch.getAddressLine(0) : "", bestMatch.getLocality(), bestMatch.getCountryName()); } @Override public void onMapLongClick(LatLng point) { // TODO Auto-generated method stub } @Override public void onMapClick(LatLng point) { // TODO Auto-generated method stub } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; }检查服务是否正常，然后继续构建地图
public boolean servicesOK() { int isAvailable = GooglePlayServicesUtil .isGooglePlayServicesAvailable(this); if (isAvailable == ConnectionResult.SUCCESS) { return true; } else if (GooglePlayServicesUtil.isUserRecoverableError(isAvailable)) { Dialog dialog = GooglePlayServicesUtil.getErrorDialog(isAvailable, this, GPS_ERRORDIALOG_REQUEST); dialog.show(); } else { Toast.makeText(this, "Cant connect!!", Toast.LENGTH_SHORT).show(); } return false; }}最后，清单：
<permission android:name="com.mike.maps.permission.MAPS_RECEIVE" android:protectionLevel="signature" /> <uses-permission android:name="com.example.mapsexample.permission.MAPS_RECEIVE" /> <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES"/> <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/> <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/> <uses-permission android:name ="android.permission.ACCESS_NETWORK_STATE"/> <uses-feature android:glEsVersion="0x00020000" android:required="true"/>
并在 应用程序标签中 ：
<meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="Your Api" />
希望这能回答您的问题.. :)
