錯誤的膨脹類的片段，我無法解決的錯誤

Question

地圖不顯示，不知道爲什麼。我無法弄清楚代碼中有什麼問題，如果問題出在xml或java中......即在我的應用程序中有一個額外的東西，它所有的運行都很流暢，但是當我點擊按鈕去MapActivity爆炸

Answer 1

你應該有SupportMapFragment

<fragment 
     android:id="@+id/map" 
     android:layout_width="match_parent" 
     android:layout_height="fill_parent" 
     android:name="com.google.android.gms.maps.SupportMapFragment"/> 

確保您擁有正確的進口。

import android.support.v4.app.FragmentActivity; 
import com.google.android.gms.maps.SupportMapFragment;
