如何在 Fragments 中使用 Google API 客户端

Question

我无法在 Fragment 中使用 Google API 客户端。

  @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.layout_case_summary, container, false);

        initView(rootView);
        return rootView;

      if(mGoogleApiClient==null) {
            mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .addApi(LocationServices.API)
                    .build();
        }
         }

它显示错误：

只需切换 return 语句和 google API 客户端初始化：

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.layout_case_summary, container, false);

    initView(rootView);

    if(mGoogleApiClient==null) {
        mGoogleApiClient = new GoogleApiClient.Builder(getActivity())
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();
    }
    return rootView;
}

return 语句应该始终是方法中的最后一行。
