Getting the Selected Picklist Value Using Apex Trigger

Question

I have two custom objects : Obj1__c and Obj2__c.

Obj1__c fields: Name, Customer__c, Date__c, Picklist__c(Red,Blue)
Obj2__c fields: Name, Customer__c, Type__c(Type1, Type2) 

I created an apex trigger wherein a new Obj1__c record must be created every time a new Obj2__c is inserted. I have no problem with this.

Here's what I need to achieve:

Picklist__c field from Obj1__c must be inserted with this value: 'Red' if Type__c from Obj2__c is equal to 'Type1', while 'Blue' if Type__c from Obj2__c is equal to 'Type2'.

I am not so sure on how to get the selected picklist value so that I can assign it on a string variable.

Meanwhile, here's what I've done so far:

trigger MyTrigger on Obj2__c (after insert) {

    String selectedPV;
    List<Obj1__c> o1List = new List<Obj1__c>();

    for(Obj2__c o2 : Trigger.New) {

        if(o2.Id != null) { 

            Obj1__c o1 = new Obj1__c();
            o1.Customer__c = o2.Customer__c;
            o1.Date__c = Datetime.now();
            o1List.add(o1);
        }
    }

    insert o1List;
}

Updated Trigger:

trigger MyTrigger on Obj2__c (after insert) {

    List<Obj1__c> o1List = new List<Obj1__c>();

    for(Obj2__c o2 : Trigger.New) {

        Obj1__c o1 = new Obj1__c();
        String selectedPV = o2.Type__c;

        if(selectedPV == 'Type1') {
            o2.Picklist__c = 'Red';
        }

        else {
            o2.Picklist__c = 'Blue';
        } 

        if(o2.Id != null) { 


            o1.Customer__c = o2.Customer__c;
            o1.Date__c = Datetime.now();
            o1.Picklist__c = selectedPV;
            o1List.add(o1);
        }
    }

    insert o1List;
}

Answer 1

You can use this logic:

if((o2.Type__c).equalsIgnoreCase('Type1'))
{
    o1.Picklist__c = 'Red';
}
else if((o2.Type__c).equalsIgnoreCase('Type2'))
{
    o1.Picklist__c = 'Blue';
}

Update Remove o1.Picklist__c = selectedPV; from the assignment as you are assigning Red or Blue depending on the if-else logic.
