Dynamic Section Header Of RecyclerView Using Current Date&Time

Ali :

I'll use RecyclerView for a section header

I want to create section header when i insert each Date & Time data in SQLite Database

I followed below links for this solution but haven't been successful

Please refer the below image

For above image data using below code OR Section is Static :

List<Company> childList = new ArrayList<>();
        List<CompanySectionHeader> sectionHeaders = new ArrayList<>();

        childList = myDb.getAllCompany();
        sectionHeaders.add(new CompanySectionHeader(childList, "WEDNESDAY 4 APRIL", 1));

Now If suppose i enter today's data then I create 1 Section Header taking today date

Below image data section header is Static or data also:

Above image data are getting using Below code :

childList.add(new Company("Ketul Inc.", "11/11/2017 3:46 PM"));
        childList.add(new Company("Atmel Corporation", "09/19/2017 8:46 PM"));
        childList.add(new Company("ABC Technologies", "09/12/2017 7:41 PM"));
        childList.add(new Company("Huron Capital Partners LLC", "09/12/2017 7:25 PM"));
        sectionHeaders = new ArrayList<>();
        //Create a List of SectionHeader DataModel implements SectionHeader
        sectionHeaders.add(new CompanySectionHeader(childList, "SATURDAY 7 APRIL", 2));

Below Code is my SectionHeader.Java :

public class CompanySectionHeader implements Section<Company>, Comparable<CompanySectionHeader> {

    List<Company> childList;
    String sectionText;
    int index;

    public CompanySectionHeader(List<Company> childList, String sectionText, int index) {
        this.childList = childList;
        this.sectionText = sectionText;
        this.index = index;
    }

    @Override
    public List<Company> getChildItems() {
        return childList;
    }

    public String getSectionText() {
        return sectionText;
    }

    @Override
    public int compareTo(CompanySectionHeader another) {
        if (this.index > another.index) {
            return -1;
        } else {
            return 1;
        }
    }
}

Below is my SQLite Database Structure:

public String getFromatDate(long dateTime) {
        String formatedDate;
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(dateTime);
        Date mDate = calendar.getTime();
        SimpleDateFormat sdf;
        sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm a", new Locale("en"));
        formatedDate = sdf.format(mDate);
        return formatedDate;
    }

    public long insertCompany(Company company){

        //String sql = null;
        SQLiteDatabase db = dbHelper.getWritableDatabase();

        ContentValues values = new ContentValues();

        values.put(DatabaseHelper.KEY_COMPANY_NAME, company.getName());
        values.put(DatabaseHelper.KEY_CREATED_AT, System.currentTimeMillis());
        values.put(DatabaseHelper.KEY_UPDATED_AT, System.currentTimeMillis());
        values.put(DatabaseHelper.KEY_COMPANY_WEBSITE,company.getWebsite());
        values.put(DatabaseHelper.KEY_COMPANY_EMAIL,company.getEmail());
        values.put(DatabaseHelper.KEY_COMPANY_PHONE_HOME,company.getPhoneHome());

        long company_id = db.insert(COMPANY, null, values);

        return company_id;
    }

My Question is How to create section header dynamically

If u need any code or information you can ask me :)

Thanks in Advance :

I had Recently done this for sorting something on Monthly Basis. Its By overriding ViewType Function .

For doing this you have to use something like getViewType() in Recycler Adapter.

public class LastTransAdapter extends RecyclerView.Adapter<LastTransAdapter.ViewHolder> {
    private ArrayList<LastTransBean> lastTransBeans;
    private Context context;

    private MyCustomTextView textViewTitle, tv_Desc, tv_Date, tv_Amount;
    private LinearLayout layout1;
    private View customView, myView;

    private LayoutParams layoutParams;

    private PopupWindow popUpWindow = null;

    private RelativeLayout layout;

    private int MONTHHEADER = 1;
    private int DATAVIEW = 2;


    public LastTransAdapter(ArrayList<LastTransBean> lastTransBeans, Context context, View myView, RelativeLayout layout) {
        this.lastTransBeans = lastTransBeans;
        this.context = context;
        this.myView = myView;
        this.layout = layout;

    }

    @Override
    public ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {

        if (i == DATAVIEW) {

             // view for normal data.


            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.single_row_last_transactions, viewGroup, false);
            return new ViewHolder(view);
        } else {

            // view type for month or date header

            View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.single_row_month_header, viewGroup, false);
            return new ViewHolder(view);
        }
    }


    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int i) {

        final int position = i;

        if (viewHolder.getItemViewType() == DATAVIEW) {

            //fill data for normal view


        } else {
            //set your date or month header
        }

    }

    @Override
    public int getItemCount() {
        return lastTransBeans.size();
    }

    @Override
    public int getItemViewType(int position) {
        if (lastTransBeans.get(position).getMonth()) {
            return MONTHHEADER;
        } else {
            return DATAVIEW;
        }
    }

    public class ViewHolder extends RecyclerView.ViewHolder {
        MyCustomTextView transtile, transdate, transamont, tv_monthHeader;
        LinearLayout acctype;
        CardView mlastTransCardView;


        public ViewHolder(View itemView) {
            super(itemView);

           // cast all the textviews , buttonsetc used ion view Holder.

        }
    }
}

You can also use multiple viewholder types. Like this example.

Hope this may help you to solve your problem
