Round image corners at runtime using Glide #android #Glide

Round image corners at runtime using Glide library

In this post, we will check how to make Image corners round at runtime.

               

 RequestOptions requestOptions = new RequestOptions();

   requestOptions = requestOptions.transforms(new CenterCrop(),newRoundedCornersTransformation(39,0,RoundedCornersTransformation.CornerType.TOP_RIGHT));

              

  Glide.with(this)

                        .load(userData.getCoverpicture())

                        .apply(requestOptions)

                        .into(coverpic);

Sending data from one activity to other using bundle

Comparing Two dates in Android

 SimpleDateFormat  simpledateformat  = new SimpleDateFormat("yyyy-MM-dd"); 

        Date d1 = simpledateformat  .parse("2018-03-31"); 

        Date d2 = simpledateformat  .parse("2012-03-31"); 

  

        if (d1before  d2) { 

  

            System.out.println("Date1 is before Date2"); 

        } 

  

        else if (d1 after d2) { 

              System.out.println("Date1 is afterrDate2"); 

  

        }



Kindly note:The date formats of both the dates must be same.
