Google Maps V2 Android作为片段工作,但显示白色屏幕(带缩放控制)作为子片段

Question

我已经研究了这个问题几天了,并且尝试过SO提供的所有内容但都没有成功.

当我跟随由谷歌列出的说明这里,我没有问题得到一般的谷歌地图显示在自定义地图碎片(QMapFragment),我FragmentActivity之下延伸SupportMapFragment.

(旁注:即使我在Manifest.xml中提供了一个伪API密钥,例如"abcd",地图仍然显示得很好.我对此感到困惑,但无论如何......)

但是当我将QMapFragment子片段添加到另一个自定义片段时,例如,使用以下代码:

mFrag = QMapFragment.newInstance(new LatLng(location.getLatitude(), location.getLongitude()));
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();

transaction.add(R.id.framelayout, mFrag).commit();

我看到一个空白的屏幕,在片段中添加了缩放控件,我在LogCat中得到了这个

不,我没有从调试器获得"授权失败",我的控制台在Google API上设置为Google Android v2.

我记得在使用 transaction.add 时遇到了同样的问题。从那时起，我的基本规则之一就是永远不再使用 transaction.add 并使用 transaction.replace 代替。尝试一下，应该可以。
