我正在尝试制作一个应用程序，在该应用程序中，当用户单击ListView中的项目时，将显示GoogleMaps。
我尝试了以下代码：
ShowPlacesActivity.java
public class ShowPlaceActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_show_place);
if (savedInstanceState == null) {
getFragmentManager().beginTransaction()
.add(R.id.container_showplaces, new PlaceholderFragment())
.commit();
}
getActionBar().setSubtitle(getString(R.string.activity_showplaces_subtitle));
}
}
activity_show_place.xml
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:id="@+id/container_showplaces"
android:layout_width="match_parent" android:layout_height="match_parent"
tools:context="com.krupal.rememberthisplace.ShowPlaceActivity" tools:ignore="MergeRootFrame" />
fragment_show_place.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:orientation="vertical"
>
<ListView
android:id="@+id/listView_places"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
/>
</LinearLayout>
fragment_maps.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<fragment
android:id="@+id/mymap"
android:name="com.google.android.gms.maps.MapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
我希望在ListView的项单击时显示地图... 因此，我已经实现了以下两个片段：
在 PlaceholderFragment.java 中，我设置了 onitemclicklistener 如下：
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_show_place, container, false);
final MySqliteHelper db = new MySqliteHelper(getActivity().getBaseContext());
listview_places = (ListView)rootView.findViewById(R.id.listView_places);
final PlacesAdapter places_adapter = new PlacesAdapter(getActivity(),R.layout.listview_item_row,places);
listview_places.setAdapter(places_adapter);
listview_places.setLongClickable(true);
listview_places.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position,long id) {
Place place = places_adapter.getItem(position);
String dbvaluename = place.getname();
Place selectedplace = db.getPlace(dbvaluename);
dblatitude = selectedplace.getlatitude();
dblongitude = selectedplace.getlongitude();
dbplacename = place.getname();
maps = new MapsFragment();
Bundle bundle = new Bundle();
bundle.putDouble("dbplacename",dblatitude);
bundle.putDouble("dbplacename",dblongitude);
bundle.putString("dbplacename",dbplacename);
maps.setArguments(bundle);
FragmentManager fm = getFragmentManager();
FragmentTransaction ft = fm.beginTransaction();
ft.replace(R.id.container_showplaces,maps);
ft.addToBackStack(null);
ft.commit();
}
});
}
}
在 MapsFragment.java 中，我展示了地图：
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
rootView = inflater.inflate(R.layout.fragment_maps, container, false);
try {
// Loading map
initilizeMap();
} catch (Exception e) {
e.printStackTrace();
}
return rootView;
}
当我第一次点击ListView的项目时，它会显示地图...然后，当我选择另一个项目时，它就会崩溃：
Logcat日志：

编辑：这个解决方案对我没有用。
