问题描述

当第二次（调用的setContentView）我收到以下错误打开我的SupportMapFragment（Android地图V2）：

When opening my SupportMapFragment (Android maps v2) for a second time (calling setContentView) I get the following error:

XML文件：

The XML file:

<?xml version="1.0" encoding="utf-8"?>

    xmlns:map="http://schemas.android.com/apk/res-auto"

MyView.class：

MyView.class:

public class MyView extends RelativeLayout {
    private GoogleMap map;

    public MyView(Context context, FragmentActivity activity) {
        super(context);
        inflate(activity, R.layout.activity_hits, this);
        this.map = ((SupportMapFragment) activity.getSupportFragmentManager()
            .findFragmentById(R.id.hits_map)).getMap();
    }
}

我不知道这是什么错误意味着。有人能解释一下吗？

I have no idea what this error means. Can someone explain this?

推荐答案

而不是声明德SupportMapFragment的布局，编程做到这一点，并确保您使用getChildFragmentMananger代替经典getFragmentManager（）创建的片段。

Instead of declaring de SupportMapFragment in layout, do it programatically and be sure you use getChildFragmentMananger instead of the classic getFragmentManager() to create the fragment.

  mMapFragment = SupportMapFragment.newInstance();
    FragmentTransaction fragmentTransaction =
             getChildFragmentManager().beginTransaction();
     fragmentTransaction.add(R.id.map_root, mMapFragment);
     fragmentTransaction.commit();

请这个SupportMapFragment mMapFragment因为你会需要它来检索的GoogleMap对象：

Keep this SupportMapFragment mMapFragment as you will need it to retrieve the GoogleMap object:

  GoogleMap map = mMapFragment.getMap();
