百度地图SDK获取Map（地图）报空指针

Question

已经尝试：
将

SDKInitializer.initialize(getActivity().getApplicationContext());

View view = inflater.inflate(R.layout.map_frag, container, false);
init(); //之后inlater view文件
...
}
public void init(){ //使用init方法
    View view = null; //是因为这里赋值给了null么？
    mMapView = view.findViewById(R.id.bmapView);

报错信息：

 java.lang.NullPointerException: Attempt to invoke virtual method 'android.view.View android.view.View.findViewById(int)' on a null object reference
