Question

拥有一个包含3个标签的应用，我使用标签主机和片段活动完成了这些标签。我在第一个选项卡中有一个地图，当我第一次启动它时工作正常，当我切换标签并返回我的应用程序崩溃并给我一个错误膨胀类异常时显示地图。

以下是我的标签中的代码更改listerner

getActivity().getSupportFragmentManager().beginTransaction().replace(placeholder, new MapView(), "Maps").commit();

以下是我的片段类中的代码

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

        view = inflater.inflate(R.layout.map_view, container, false);

    return view;
}

这是我的logcat

Vidar在这里回答：Duplicate ID, tag null, or parent id with another fragment for com.google.android.gms.maps.MapFragment

他的解决方案是：

if (view != null) {
    ViewGroup parent = (ViewGroup) view.getParent();
    if (parent != null)
        parent.removeView(view);
}
try {
    view = inflater.inflate(R.layout.map, container, false);
} catch (InflateException e) {
    /* map is already there, just return view as it is */
}
return view;
