【问题描述】:
我正在构建一个包含两个选项卡主机(顶部和底部)的应用程序,并且在一个选项卡中,我想通过 Google API 放置一个 Google 地图。一切正常,但地图显示不正确。您可以在这张图片中看得更清楚:
我的代码是:
fragment_mapa.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/map_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>
</RelativeLayout>
MapaFragment.java
public class MapaFragment extends Fragment {
public MapaFragment(){}
public GoogleMap mapa;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_mapa, container, false);
if (container != null) {
container.removeAllViews();
}
GoogleMap map = ((SupportMapFragment) getActivity().getSupportFragmentManager()
.findFragmentById(R.id.map)).getMap();
((MainActivity) getActivity()).setBar();
//Asigno el nombre de la vista e integro tabhost-sliding
((MainActivity) getActivity()).setTitle("Mapa");
((MainActivity) getActivity()).integrationMenu();
return rootView;
}
public void onDestroyView() {
super.onDestroyView();
Log.d("DESTROY", "onDestroyView");
Fragment f = getActivity()
.getSupportFragmentManager().findFragmentById(R.id.map);
if (f != null) {
getActivity().getSupportFragmentManager()
.beginTransaction().remove(f).commit();
}
}
}
还有我的activity_main.xml,其中包含两个tabhost和一个调用片段的framelayout:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"

</RelativeLayout>
