  试试我的其他帖子 . 我已经详细解释了 Map 的工作原理 .

  您现在应该可以使用 Map 了 .

  Want to use GoogleMaps - OnMyLocationChangeListener but can't implement it? Any other options

  这是我正在使用的 Map 的布局代码段：

  <fragment
          android:id="@+id/map"
          android:layout_width="match_parent"
          android:layout_height="250dp"
          class="com.google.android.gms.maps.SupportMapFragment" />
  

  许可是这样的：

  <?xml version="1.0" encoding="utf-8"?>
  <manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.mike.mylocation"
      android:versionCode="1"
      android:versionName="1.0" >
  
      <uses-sdk
          android:minSdkVersion="8"
          android:targetSdkVersion="19" />
  
      <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="android.permission.WRITE_EXTERNAL_STORAGE" />
      <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

      <uses-feature
          android:glEsVersion="0x00020000"
          android:required="true" />
  
      <application
          android:allowBackup="true"
          android:icon="@drawable/ic_launcher"
          android:label="@string/app_name"
          android:theme="@style/AppTheme" >
          <activity
              android:name="com.mike.mylocation.HomeActivity"
              android:label="@string/app_name" >
              <intent-filter>
                  <action android:name="android.intent.action.MAIN" />
  
                  <category android:name="android.intent.category.LAUNCHER" />
              </intent-filter>
          </activity>
  
          <meta-data
              android:name="com.google.android.gms.version"
              android:value="@integer/google_play_services_version" />
          <meta-data
              android:name="com.google.android.maps.v2.API_KEY"
              android:value="YOUE API WILL GO HERE" />
      </application>
  
  </manifest>
  

  另外不要忘记使用这些 callbacks 或你的电池将被耗尽..：p

  @Override
      protected void onPause() {
  
          super.onPause();
          locationManager.removeUpdates(this);
  
      }
  
  
      @Override
      protected void onDestroy() {
          // TODO Auto-generated method stub
          super.onDestroy();
          locationManager.removeUpdates(this);
      }
  
  
      @Override
      protected void onResume() {
          // TODO Auto-generated method stub
          super.onResume();
          locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                  1, this);
      }
  

  EDIT:

  如果对上一个答案有疑问，请参考以下代码：

  1) In your MainActivity, extend the Fragment Activiy and implement LocationListener, OnMapClickListener, OnMapLongClickListener 喜欢这个：

  public class MainActivity extends FragmentActivity implements LocationListener,
          OnMapClickListener, OnMapLongClickListener {
  
  private static final int GPS_ERRORDIALOG_REQUEST = 9001;
  
      GoogleMap map;
      List<Address> matches;
      String addressText;
      String addressLine;
      double latitude;
      double longitude;
      AppUtils mAppUtils;
      Context context;
      LocationManager locationManager;
  
  @Override
      protected void onCreate(Bundle savedInstanceState) {
          super.onCreate(savedInstanceState);
          context = this;
  
          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) 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

      @Override

          //This is the main stuff here. This is when the location is changed.
          @Override

          // 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(12));
  
          map.addMarker(
                  new MarkerOptions().position(new LatLng(latitude, longitude))
                          .title("My Location" + "\n")).showInfoWindow();
  
          map.setOnMarkerClickListener(new GoogleMap.OnMarkerClickListener() {
  
              @Override
              public boolean onMarkerClick(Marker marker) {
  
                  marker.showInfoWindow();
  
                  return false;
              }
  
          });
  
  
              //This is optional........................................................
          Geocoder geoCoder = new Geocoder(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
  
      }
  
  //Check if the service is OK
  
  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;
      }
  
      @Override
      protected void onPause() {
  
          super.onPause();
          locationManager.removeUpdates(this);
  
      }
  
  
      @Override
      protected void onDestroy() {
          // TODO Auto-generated method stub
          super.onDestroy();
          locationManager.removeUpdates(this);
      }
  
  
      @Override
      protected void onResume() {
          // TODO Auto-generated method stub
          super.onResume();
          locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0,
                  1, this);
      }
  

  2) Layout is the same as mentioned above.

  希望这有帮助.. :)
