Question

I have to develop an one android application.

Here i have to get the list of items and set that list of item value in android spinner.

So i have using following code:

if (getIntent().getExtras() !=null) {
    retailerNamesList = (ArrayList<RetailerNames>) getIntent().getExtras().getSerializable("RetailerName");

    for (int i=0;i<retailerNamesList.size();i++) {}

    mRetailerNameAdapter = new RetailerNamesAdapter(WatchList.this,retailerNamesList);
    retailerlist.setAdapter(mRetailerNameAdapter);
}

Here i get the list of arraylist values in that spinner.but i have to split these values and set it in android spinner.please help me.how can i do ???

EDIT:

In the above code am getting the output like:

[com.example.RetailerNames@41216470]

But i need to get the output like:

String[] period_timings={"0-2 days","Within a Week","Within a Month"};

That list have to split and get the values in string[].How can i write the code for these ??? please provide me solution for these ???

 for (int i=0;i<retailerNamesList.size();i++){
     retailerNamesList.get(i);
 }

or if you really have to create an array of it then

 final int nameListSize = retailerNamesList.size();
 String []names = new String[nameListSize];
 for (int i=0;i<nameListSize ;i++){
     names[i] = retailerNamesList.get(i);
 }
 // use the string array names to set wherever u need.

@user2218667 Implement a toString() method in your RetilerNames class. You can autogenerate that method using eclipse: right click on your class->Source->Generate toString(). The string you return from that method, will be used for printing the object.
