我尝试了所有的东西，但它仍然崩溃了。有人请帮助我。这是我的地图代码。 我成功实现了具有片段活动和支持片段的地图（作为单独的项目）。但是当我试图在我们的主项目中实现这是一个片段而不是片段活动时，我尝试使用片段管理器等但都是徒劳的：（
我做了我在其他帖子中看到的所有内容，例如使用mapview，尝试使用catch for layout inflate ..但没有任何效果
我的完整代码非常冗长。我想在该代码中实现一个地图视图/支持片段。所以我只写了实现map的部分。并在哪里发生问题。我这在布局上有一些问题。因为每次都会发生布局崩溃。
public class EventFragment extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
if (container == null) {
return null;
}
if (rootView != null) {
ViewGroup parent = (ViewGroup) rootView.getParent();
if (parent != null)
parent.removeView(rootView);
}
try {
rootView = inflater.inflate(R.layout.workspace_event_fragment_layout, container, false);
} catch (Exception e1) {
// TODO Auto-generated catch block

return rootView;

答案 0 :(得分：4)
解决：
使用<FrameLayout/>代替<Fragment/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1.03"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:id="@+id/mapwhere" />
和
public class WhereFragment extends SupportMapFragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
super.onCreateView(inflater, container, savedInstanceState);
View root = inflater.inflate(R.layout.where, null, false);
initilizeMap();
return root;
}
private void initilizeMap()
{
mSupportMapFragment = (SupportMapFragment) getFragmentManager().findFragmentById(R.id.mapwhere);
if (mSupportMapFragment == null) {
FragmentManager fragmentManager = getFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
mSupportMapFragment = SupportMapFragment.newInstance();
fragmentTransaction.replace(R.id.mapwhere, mSupportMapFragment).commit();
}
if (mSupportMapFragment != null)
{
googleMap = mSupportMapFragment.getMap();
if (googleMap != null)
googleMap.setOnMapClickListener(new OnMapClickListener()
{
@Override
public void onMapClick(LatLng point)
{
//TODO: your onclick stuffs
}
});
}
}
}
答案 1 :(得分：2)
不支持您尝试做的事情。见here。这来自开发人员文档：
注意：当布局包含a时，您无法将布局扩展为片段。只有动态添加到片段时才支持嵌套片段。
它基本上说的如下。考虑一个 MyClass
类public class MyClass extends Fragment{
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// TODO Auto-generated method stub
View view = inflater.inflate(R.layout.fragment_myclass, container,
false);
return view;
}
}
布局文件 fragment_myclass 不能包含＆lt; fragment /＆gt; 标记为元素。
