Use the below methods to close the quick action popup and refresh the page from custom Salesforce Lightning Component.

                $A.get(“e.force:closeQuickAction”).fire();
                $A.get(‘e.force:refreshView’).fire();


Sample code:

Lightning Aura Component:

Component:

<aura:component implements=”force:hasRecordId,force:lightningQuickActionWithoutHeader” controller=”Sample” >  

      

    <div class=”slds-box slds-theme_default”>   

        <ui:button aura:id=”mybtn” class=”slds-button slds-button–brand slds-size–1-of-1″ label=”Testing” press=”{!c.onclick}” />  

    </div>  

      

</aura:component>  

Component Controller:

({      

      

    onclick : function(component, event, helper) {  

          

        var action = component.get( “c.firstMethod” );  

        action.setCallback(this, function(response){  

            var state = response.getState();  

            if (state === “SUCCESS”) {  

                  

                alert( response.getReturnValue() );  

                $A.get( “e.force:closeQuickAction” ).fire();  

                $A.get( “e.force:refreshView” ).fire();  

                  

            }  

        });  

        $A.enqueueAction(action);  

          

    }  

      

})  

Apex Class:

public class Sample {  

  

    @AuraEnabled  

    public static String firstMethod() {  

        return ‘Success’;  

    }  

  

}
