java - 使用 fragment 膨胀 map 时出错

Question

我看过很多关于这个错误的帖子，我几乎尝试了所有的帖子，但它没有解决我的问题...问题是我有一个 fragment ，我想把它放在MapView，那么问题是当我尝试充气时它崩溃了......

我已经在 list 上添加了所有内容，我已经添加了库等等...

MainActivity.java(我尝试将 FragmentActivity 放在 PhotosFragment.java 上，但我遇到了这种情况)

private void displayView(int position) {
    // update the main content by replacing fragments
    Fragment fragment = null;
    switch (position) {
    case 1:
        fragment = new PhotosFragment();
        break;

在我的 PhotosFragment.java 上我尝试了这段代码:

public class PhotosFragment extends Fragment {

public PhotosFragment(){}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    return inflater.inflate(R.layout.fragment_photos, container, false); //PhotosFragment.java:20
}

}

我的fragment_photos.xml就像:

<?xml version="1.0" encoding="utf-8"?>
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:name="com.google.android.gms.maps.SupportMapFragment"/>

我有 android:name="com.google.android.gms.maps.MapFragment" 并且我读到您必须放置 SupportMapFragment。

尝试删除 onDestroyView() 中的所有嵌套 fragment ，并在 onCreateView 中膨胀它们，如 this answer建议。
