错误夸大类片段-sherlockactionbar Google Map v2

Question

我正在尝试使用SherlockActivtiyBar在一个片段中开发一个Google Android Map v2。

我有这个错误：

04-12 10:01:26.830: E/AndroidRuntime(1089): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.it.michele.ab.map/it.michele.prova.MainActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

你能帮助我吗？

我做错了什么？

这是我的Eclipse项目：

这是我的代码：
SherlockMapFragment.java

        public SherlockFragmentActivity getSherlockActivity() {
            return mActivity;
        }

        @Override

            if (!(activity instanceof SherlockFragmentActivity)) {
                throw new IllegalStateException(getClass().getSimpleName() + " must be attached to a SherlockFragmentActivity.");
            }
            mActivity = (SherlockFragmentActivity)activity;

            super.onAttach(activity);
        }

        @Override

        }

        @Override

        }

        @Override

            return false;
        }
    }

Answer 1

通常，如果在使用地图时收到fragment/class not found error ，则您的问题可能是缺少google-play-services库的良好参考，因为MapFragment / SupportMapFragment是该库的一部分：

检查您的Android Dependencies文件夹(blue)包含google-play-services (orange) ，您会发现com.google.android.gms.maps包(green)具有MapFragment类(red) ：

如果不是这种情况，您可以查看我撰写此博客文章的前3个步骤，并获得有关如何正确引用此软件包的想法：

Answer 2

我花了几天的时间来解决这个问题。 就我而言，我没有在我的android清单中引用开放式GL es v2-一旦我将其放入其中，错误就会消失并且我的地图显示出来。 将语句添加到您的android manifest权限中（如果尚未存在的话）-可能会为您解决。
