我想在我的应用程序中实现谷歌地图...我有地图api密钥并在我的xml文件中使用它但谷歌地图没有显示。当我将片段添加到xml文件时,它会导致强制关闭错误,当我更正此错误时,谷歌地图不会在运行时显示。 谢谢你的帮助。

public class MainActivity extends FragmentActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}

使用以下代码:
片段代码:
public static class MapsFragment extends Fragment {
private SupportMapFragment suppfrag;
static final LatLng myLoc = new LatLng(//latitiude and longitude here);
private GoogleMap map;
public static final String ARG_SECTION_NUMBER = "section_number";
public MapsFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_map, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
FragmentManager fm = getChildFragmentManager();
suppfrag = (SupportMapFragment) fm.findFragmentById(R.id.map);
if (suppfrag == null) {
suppfrag = SupportMapFragment.newInstance();
fm.beginTransaction().replace(R.id.map, suppfrag).commit();
Marker location = map.addMarker(new MarkerOptions().position(CENTRU)
.title("Centru"));
location.setIcon(BitmapDescriptorFactory
.defaultMarker(BitmapDescriptorFactory.HUE_BLUE));
// Move the camera instantly to Bottlecapp with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(CENTRU, 15));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(10), 2000, null);
getActivity().getSupportFragmentManager().popBackStack();
}
}
@Override
public void onResume() {
super.onResume();
if (map == null) {
map = suppfrag.getMap();
map.addMarker(new MarkerOptions().position(new LatLng(0, 0)));
}
}
}
