錯誤誇大類片段-sherlockactionbar Google Map v2

Question

我正在嘗試使用SherlockActivtiyBar在一個片段中開發一個Google Android Map v2。

我有這個錯誤：

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

你能幫助我嗎？

我做錯了什么？

這是我的Eclipse項目：

這是我的代碼：
SherlockMapFragment.java

            }
            mActivity = (SherlockFragmentActivity)activity;

        }

Answer 1

通常，如果在使用地圖時收到fragment/class not found error ，則您的問題可能是缺少google-play-services庫的良好參考，因為MapFragment / SupportMapFragment是該庫的一部分：

檢查您的Android Dependencies文件夾(blue)包含google-play-services (orange) ，您會發現com.google.android.gms.maps包(green)具有MapFragment類(red) ：

如果不是這種情況，您可以查看我撰寫此博客文章的前3個步驟，並獲得有關如何正確引用此軟件包的想法：

Answer 2

我花了幾天的時間來解決這個問題。 就我而言，我沒有在我的android清單中引用開放式GL es v2-一旦我將其放入其中，錯誤就會消失並且我的地圖顯示出來。 將語句添加到您的android manifest權限中（如果尚未存在的話）-可能會為您解決。
