Question

这是我的logcat：实际上我正面临着抽屉里的地图。我尽我所能，但仍然缺少一些东西。试图显示像卫星，普通，混合等地图类型这里是我的代码。点击抽屉时出现错误。我在这里贴了我的原木猫。如果此处有人有任何建议请分享：

你的地图碎片第二次骑了..所以，你就像下面那样摧毁：

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

并覆盖方法OnDestroyView并将此代码放在OnDestroyView（）

上

public void onDestroyView() 
 {
    super.onDestroyView(); 
    Fragment fragment = (getFragmentManager().findFragmentById(R.id.map));  
    FragmentTransaction ft = getActivity().getSupportFragmentManager().beginTransaction();
    ft.remove(fragment);
    ft.commit();
}
