Question

我正在子菜单中创建一个带子菜单的导航，但它无法正常工作。我已经尝试过互联网上的样本，但是当我实施它时。我遇到了一些问题。我无法正确定位子菜单。我是新手，我希望你能帮助我。

public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    ViewPager postImagesViewPager;
        ImagePipeline imagePipeline = Fresco.getImagePipeline();
        Uri uri = Uri.parse(CommonUtilities.SERVER_IMAGE_URL +"user_background_" +userid+ ".jpeg?w=600&h=300"); 
        ImageRequest request = ImageRequestBuilder.newBuilderWithSource(uri).build();
        DataSource<CloseableReference<CloseableImage>> dataSource = imagePipeline.fetchDecodedImage(request,getActivity());

    DataSubscriber<CloseableReference<CloseableImage>> dataSubscriber =  new BaseDataSubscriber<CloseableReference<CloseableImage>>() {

        @Override
        protected void onFailureImpl(DataSource<CloseableReference<CloseableImage>> arg0) {
            // TODO Auto-generated method stub
            System.out.println("Failed");
        }
        @Override
        protected void onNewResultImpl( DataSource<CloseableReference<CloseableImage>> arg0) {
            // TODO Auto-generated method stub
            if (!arg0.isFinished()) {
              System.out.println("Not yet finished - this is just another progressive scan.");
            }  

            CloseableReference<CloseableImage> imageReference = arg0.getResult();
            if (imageReference != null) {
              try {
                  CloseableBitmap image = (CloseableBitmap)imageReference.get();
                  Bitmap bitmap = image.getUnderlyingBitmap();
                  viewpagerDrawable = new BitmapDrawable(context.getResources(),bitmap);
                  postImagesViewPager.setBackground(viewpagerDrawable);

              } catch(Exception e){
                  e.printStackTrace();
              }
              finally {
                imageReference.close();
              }
            }
        }
    };
    Executor ex = new Executor() {
        @Override
        public void execute(Runnable command) {
            command.run();
        }
    };
    Runnable runr = new Runnable() {
        @Override
        public void run() {
            System.out.println("Runnig to get image from facebook.......");
        }
    };
    dataSource.subscribe(dataSubscriber, ex);
    ex.execute(runr);

    return _rootView;
}

SELECT  A.MONTH,(SELECT SUM(AMOUNT) FROM V_HR_PP_PROCESS_DATA 
WHERE EMPLOYER_CODE = A.EMPLOYER_CODE AND TAX_YEAR = A.TAX_YEAR AND 
PROCESS_MONTH = A.MONTH AND EMPLOYEE_ID IN 
(SELECT EMPLOYEE_ID FROM I_HR_EMP_EMPLOYMENT_DTL 
WHERE EMPLOYER_CODE = A.EMPLOYER_CODE AND CONTRACT_TERM = 'P') AND 
PROCESS_MONTH BETWEEN 1 AND 10 AND PD_CODE = 'Z500') AS GROSS_PERMANENT,
(SELECT EMPLOYEE_NAME FROM I_HR_EMPLOYEE_MASTER),
(SELECT SUM(AMOUNT) FROM V_HR_PP_PROCESS_DATA WHERE EMPLOYER_CODE = A.EMPLOYER_CODE 
AND TAX_YEAR = A.TAX_YEAR AND PROCESS_MONTH = A.MONTH AND EMPLOYEE_ID IN
(SELECT EMPLOYEE_ID FROM I_HR_EMP_EMPLOYMENT_DTL WHERE EMPLOYER_CODE = A.EMPLOYER_CODE 
AND CONTRACT_TERM = 'F') AND PROCESS_MONTH BETWEEN  1 AND 10 AND PD_CODE = 'Z500') 
AS GROSS_CASUAL  FROM I_HR_SYS_DATE_MONTHLY A WHERE A.EMPLOYER_CODE = 'RAD' AND 
A.TAX_YEAR = 2014

我真的需要帮助。谢谢！
