我很难为我的谷歌地图页面调试主java类。每当我运行我的应用程序时，我总是得到一个无响应输出。感谢那些愿意回答的人。
以下是地图的java代码：
public class MapsActivity extends FragmentActivity {
private GoogleMap map;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
setUpMapIfNeeded();
}
@Override
protected void onResume() {
super.onResume();
setUpMapIfNeeded();
}
public void onSearch(View view) {
EditText location_tf = (EditText) findViewById(R.id.TFPickup);
String location = location_tf.getText().toString();
List<Address> addressList = null; //stores the list of address
if (location != null || !location.equals("")) {
Geocoder geocoder = new Geocoder(this);
try {
addressList = geocoder.getFromLocationName(location, 1);
} catch (IOException e) {
e.printStackTrace();
}
Address address = addressList.get(0); //stores lang and long
LatLng latLng = new LatLng(address.getLatitude(), address.getLongitude());
map.addMarker(new MarkerOptions().position(latLng).title("You are here!"));
map.animateCamera(CameraUpdateFactory.newLatLng(latLng));
}
}
private void setUpMapIfNeeded() {
if (map == null) {
// Try to obtain the map from the SupportMapFragment.
map = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map))
.getMap(); //creates map fragment //getmap- initializes map and view
// Check if we were successful in obtaining the map.
if (map != null) {
setUpMap();
}
}
}
private void setUpMap() {
map.addMarker(new MarkerOptions().position(new LatLng(0,0)).title("You are here!"));
map.setMyLocationEnabled(true); //see current location
}
}
以下是地图的xml文件：

And here is the function to call the map activity page:
case R.id.bBook:
userLocalStore.getLoggedInUser();
userLocalStore.setUserLoggedIn(true);
startActivity(new Intent(this, MapsActivity.class));
break;

Geocoder geocoder = new Geocoder(this);
应该是
Geocoder geocoder = new Geocoder(getActivity());
