Java Android Recyclerview Slide or Swipe to Right or Horizontally

Hi there. Generally, the usage of recyclerview is vertically. This following script, recyclerview is used to display list items that previously uscrolled down to horizontally or swipe to the right.

On Adapter Class create add this variable :

private RecyclerView rvItemList; 
private RecyclerView.LayoutManager layoutManager; 
private RecyclerView.Adapter adapterList;

after looping creating listData :

mContext = this; // Context

rvItemList = (RecyclerView) findViewById(R.id.rv_list); //recyclerview
rvItemList.setHasFixedSize(true); 
layoutManager = new LinearLayoutManager(mContext);
rvItemList.setLayoutManager(layoutManager);
adapterQuestions = new RvQuizFormAdapter(listData, mContext);
 
//vertical or horizontal located on this options rvItemList.setLayoutManager( 
     new LinearLayoutManager(getApplicationContext(), LinearLayoutManager.HORIZONTAL, false)
);
rvItemList.setAdapter(adapterQuestions);

Done !!

C dotnet Linq Adds a Condition if Not Empty Value

To remind me

This post contains a custom LINQ database query that will includes conditions if there are exist variables and ignores conditions on empty variables.

Following is an example in one method:


/* returning json value
 * with three conditions : vesselId, portCode, filterYear
 */

public JsonResult GetEvents(Decimal? vesselId, string portCode, string filterYear)
        {
            using (dbEntities dc = new dbEntities()) //define entities
            {
                var events = new List(); //define variable on searching table


                if(vesselId == 0) { vesselId = null; } //state variable condition to null value
                if (portCode.Equals("0")) { portCode = null; }//state variable condition to null value

                var qry = from sched in dc.TABLE select sched; //starting query

                if (vesselId != null) //state first condition if not null
                {
                    qry = qry.Where(n => n.VSL_ID== vesselId);
                }
                if ( !String.IsNullOrEmpty(portCode))//state second condition if not null
                {
                    qry = qry.Where(n => n.PORT.Equals(portCode));
                }
                if (!String.IsNullOrEmpty(filterYear))//state third condition if not null
                {
                    qry = qry.Where(n => n.YEAR.Equals(filterYear));
                }

                events = qry.ToList();


                return new JsonResult { Data = events, JsonRequestBehavior = JsonRequestBehavior.AllowGet }; // returning as json value
            }
        }
That's it,,
