Question

我有一个带有3个标签的基本导航。其中一个包含一个带谷歌地图的片段。但是导航效果不好，我第二次选择标签后就会崩溃。

它说这是因为地图的XML文件在我看来没有任何错误。任何人都可以看到我现在被蒙蔽的错误吗？

任何帮助将不胜感激，提前谢谢！

Answer 1

您必须在包含地图的片段的onDestroyView()方法中删除MapFragment，并引用this answer，您必须执行以下操作：

// override the onDestroyView of the fragment
@Override
public void onDestroyView() {
    super.onDestroyView();
    MapFragment f = (MapFragment) getFragmentManager()
                                         .findFragmentById(R.id.the_map);
    if (f != null) 
        getFragmentManager().beginTransaction().remove(f).commit();
}

Answer 2

每次检查您的父视图是否为空。如果是，则删除。更改 Maps.java 。

private static View view;    
@Override
public View onCreateView(LayoutInflater inflater,ViewGroup group,Bundle bundle)
{
    if(view!=null)
    {
        ViewGroup parent =(ViewGroup)view.getParent();
        if(parent!=null)
            parent.removeView(view);
    }
    try{
        view=inflater.inflate(R.layout.maps, group, false);
        ........

    }
    catch(Exception e)
    {
        Log.e("ERROR", ""+e);
    }

    return view;
}
