Get Recycler View Items In Spinner In Another Activity

I use retrofit2 to get a category list with a model class and recyclerview adapter to get category items. In another activity I have a spinner to show category items. How can I get

Solution 1:

You were doing fine, now in the other activity, on your onCreate() method, do this:

Intent intent = getIntent();
    catId = intent.getStringExtra("catid");
    catTitle = intent.getStringExtra("cattitle");


    String[] x = newString[]{catId,catTitle};
    ArrayAdapter<String> adapterX = newArrayAdapter<>(this, android.R.layout.your_spinner_in_xml, x);
    spinner.setAdapter(adapterX);

Solution 2:

If i get question you want access to List in two activity. If so then you have several way

1 : Store To local Database or SharedPreferences

2 : use static variables(easy way)

When you get list of category from retrofit response, store it to static List like below

publicstaticList<Category> cats;

Then in OnResponse()

cats = response.body().getCats();

Now you access cats in anOther activtiy.
