See below Custom dropdown/popup code:



case R.id.linerSort:
                PopupMenu popup = new PopupMenu(activity, linerSort);
                //Inflating the Popup using xml file
                popup.getMenuInflater()
                        .inflate(R.menu.popup, popup.getMenu());

                //registering popup with OnMenuItemClickListener
                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    public boolean onMenuItemClick(MenuItem item) {
                        Toast.makeText(
                                activity,
                                "You Clicked : " + item.getTitle(),
                                Toast.LENGTH_SHORT
                        ).show();
                        return true;
                    }
                });

                popup.show();
                break;




    

  • Now i want to sorting a list which i select a item of Dropdown/popup.
    • 

  • Sorting is according to ArrayList<Object> So how to do that with my code.
    • 

  • if suppose i select a price then is shorting a acceding or descending order. 
    • 




i follow this link: How to sort ArrayList<Object> in Ascending order android But how to i merge with my code i don't understand.









Try below code to sort in ascending or descending order:



case R.id.HighToLow:
          Collections.sort(subCategoryViewDataBeanArrayList, new Comparator<SubCategoryViewDataBean>() {
          @Override
          public int compare(SubCategoryViewDataBean s1, SubCategoryViewDataBean s2) {
          return Integer.parseInt(String.valueOf(s2.price)) - Integer.parseInt(String.valueOf(s1.price));
          }
        });
        BindData(subCategoryViewDataBeanArrayList);
        break;

        case R.id.LowToHigh:
                    Collections.sort(subCategoryViewDataBeanArrayList, new Comparator<SubCategoryViewDataBean>() {
                     @Override
                     public int compare(SubCategoryViewDataBean s1, SubCategoryViewDataBean s2) {
                     return Integer.parseInt(String.valueOf(s1.price)) - Integer.parseInt(String.valueOf(s2.price));

                     }
                  });
                  BindData(subCategoryViewDataBeanArrayList);

解决方案









尝试以下代码按升序或降序排序：



case R.id.HighToLow:
          Collections.sort(subCategoryViewDataBeanArrayList, new Comparator<SubCategoryViewDataBean>() {
          @Override
          public int compare(SubCategoryViewDataBean s1, SubCategoryViewDataBean s2) {
          return Integer.parseInt(String.valueOf(s2.price)) - Integer.parseInt(String.valueOf(s1.price));
          }
        });
        BindData(subCategoryViewDataBeanArrayList);
        break;

        case R.id.LowToHigh:
                    Collections.sort(subCategoryViewDataBeanArrayList, new Comparator<SubCategoryViewDataBean>() {
                     @Override
                     public int compare(SubCategoryViewDataBean s1, SubCategoryViewDataBean s2) {
                     return Integer.parseInt(String.valueOf(s1.price)) - Integer.parseInt(String.valueOf(s2.price));

                     }
                  });
                  BindData(subCategoryViewDataBeanArrayList);
