首先要获取当前位置：
private Location mCurrentLocation;
mCurrentLocation = mLocationClient.getLastLocation();
阅读此处了解更多信息。
然后您可以使用以下方法为该位置设置动画：
LatLng myLaLn = new LatLng(mCurrentLocation.getLatitude(), mCurrentLocation.getLongitude());
CameraPosition camPos = new CameraPosition.Builder().target(myLaLn)
.zoom(15)
.bearing(45)
.tilt(70)
.build();
CameraUpdate camUpd3 = CameraUpdateFactory.newCameraPosition(camPos);
map.animateCamera(camUpd3);
我给你一个简单但完整的例子来显示地图和当前位置：
public class MainActivity extends FragmentActivity implements
GooglePlayServicesClient.ConnectionCallbacks,
GooglePlayServicesClient.OnConnectionFailedListener {
private final static int CONNECTION_FAILURE_RESOLUTION_REQUEST = 9000;
private LocationClient mLocationClient;
private Location mCurrentLocation;
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.map);
}
@Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
setUpLocationClientIfNeeded();
mLocationClient.connect();
}
private void setUpMapIfNeeded() {
// Do a null check to confirm that we have not already instantiated the
// map.
if (map == null) {
// Try to obtain the map from the SupportMapFragment.
map = ((SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
// Check if we were successful in obtaining the map.
if (map == null) {
Toast.makeText(this, "Google maps not available",
Toast.LENGTH_LONG).show();
}
}
}
private void setUpLocationClientIfNeeded() {
if (mLocationClient == null) {
Toast.makeText(getApplicationContext(), "Waiting for location",
Toast.LENGTH_SHORT).show();
mLocationClient = new LocationClient(getApplicationContext(), this, // ConnectionCallbacks
this); // OnConnectionFailedListener
}
}
@Override
public void onPause() {
super.onPause();
if (mLocationClient != null) {
mLocationClient.disconnect();
}
}
/*
* Called by Location Services when the request to connect the client
* finishes successfully. At this point, you can request the current
* location or start periodic updates
*/
@Override
public void onConnected(Bundle dataBundle) {
mCurrentLocation = mLocationClient.getLastLocation();
if (mCurrentLocation != null) {
Toast.makeText(getApplicationContext(), "Found!",
Toast.LENGTH_SHORT).show();
centerInLoc();
}
}
private void centerInLoc() {
LatLng myLaLn = new LatLng(mCurrentLocation.getLatitude(),
mCurrentLocation.getLongitude());
CameraPosition camPos = new CameraPosition.Builder().target(myLaLn)
.zoom(15).bearing(45).tilt(70).build();
CameraUpdate camUpd3 = CameraUpdateFactory.newCameraPosition(camPos);
map.animateCamera(camUpd3);
MarkerOptions markerOpts = new MarkerOptions().position(myLaLn).title(
"my Location");
map.addMarker(markerOpts);
}
/*
* Called by Location Services if the connection to the location client
* drops because of an error.
*/
@Override
public void onDisconnected() {
// Display the connection status
Toast.makeText(this, "Disconnected. Please re-connect.",
Toast.LENGTH_SHORT).show();
}
/*
* Called by Location Services if the attempt to Location Services fails.
*/
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
/*
* Google Play services can resolve some errors it detects. If the error
* has a resolution, try sending an Intent to start a Google Play
* services activity that can resolve error.
*/
if (connectionResult.hasResolution()) {
try {
// Start an Activity that tries to resolve the error
connectionResult.startResolutionForResult(this,
CONNECTION_FAILURE_RESOLUTION_REQUEST);
/*
* Thrown if Google Play services canceled the original
* PendingIntent
*/
} catch (IntentSender.SendIntentException e) {
// Log the error
e.printStackTrace();
}
} else {
/*
* If no resolution is available
*/
Log.e("Home", Integer.toString(connectionResult.getErrorCode()));
}
}
}
注意 1：为了简单起见，我省略了“检查 Google Play 服务”部分，但应将其添加为一种好的做法。
注意 2：您需要google-play-services_lib项目并从您的项目中引用它。
您可以在此处找到有关在 android 中与谷歌地图交互的所有信息
从上面引用的谷歌地图文档中，只是一些例子：
缩放控件：
Maps API 提供了显示在地图右下角的内置缩放控件。这些默认启用，但可以通过调用禁用 UiSettings.setZoomControlsEnabled(boolean)。
我的位置按钮：
仅当启用 My Location 图层时，My Location 按钮才会出现在屏幕的右上角。当用户单击该按钮时，如果用户的位置当前已知，则相机会生成动画以聚焦于用户的当前位置。单击也会触发 GoogleMap.OnMyLocationButtonClickListener。您可以通过调用来完全禁止按钮出现 UiSettings.setMyLocationButtonEnabled(boolean)。
添加标记：
下面的示例演示了如何向地图添加标记。标记在坐标 0,0 处创建，并在单击时在信息窗口中显示字符串“Hello world”。
private GoogleMap mMap;
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
mMap.addMarker(new MarkerOptions()
.position(new LatLng(0, 0))
.title("Hello world"));
