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();
    }
}

我不知道这个错误是什么意思.有人能解释一下吗?

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

推荐答案

不要在布局中声明 de SupportMapFragment，而是以编程方式进行，并确保使用 getChildFragmentMananger 而不是经典的 getFragmentManager() 来创建片段.

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

保留这个 SupportMapFragment mMapFragment，因为您需要它来检索 GoogleMap 对象:

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

  GoogleMap map = mMapFragment.getMap();
