任何想法都将受到欢迎。在对android.app.Fragment与android.app.support.v4.Fragment进行了深入的比较之后，答案是：Robolectic无法膨胀碎片，因为谷歌服务无法为其提供。所以，一个解决方案是像这样指定碎片膨胀器
public class MyFragment extends com.google.android.gms.maps.SupportMapFragment{
static private MyFragment fragment = new MyFragment();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_stub_for_test, container);
return view;
}
// public constructor must be empty
static public MyFragment getInstance(){
return fragment;
}
}
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView
android:id="@+id/tvDisplayText"
android:layout_width="wrap_content"

android:text="No Passed Bundle :(" />
</LinearLayout>
对于8.1.0以上版本的play services和play services maps，所有的测试现在都很好。在对android.app.Fragment和android.app.support.v4.Fragment进行了一些深入的比较之后，答案是：Robolectic无法膨胀碎片，因为谷歌服务不适用于它。所以，一个解决方案是像这样指定碎片膨胀器
public class MyFragment extends com.google.android.gms.maps.SupportMapFragment{
static private MyFragment fragment = new MyFragment();
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_stub_for_test, container);
return view;
}
// public constructor must be empty
static public MyFragment getInstance(){
return fragment;
}
}
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

<TextView

</LinearLayout>
现在，对于8.1.0以上版本的play services和play services maps，所有测试都正常。问题显然是Robolectric无法找到
