Show sharedpreference inside RecyclerView Adapter

Question

I have problem to pass context from Activity to Adapter.

I am calling my sharedpreference like this:

    SharedPreferences pref = PreferenceManager
            .getDefaultSharedPreferences(ctx);
    String userObject = pref.getString(key, null);

And this one need context, so i am using : getApplicationContext()

But this not work in the Adapter (RecyclerView), is there someone facing the same issue ?

Adding the adapter into the Manifest file will solve the problem ? (Just a suggestion)

Answer 1

I am not sure what you are asking but here is a solution that I can think of. Pass the context of the calling activity in your adapter through constructor and then use that context.

Context ctx;

public YourAdapter(Context ctx){
    this.ctx = ctx;
}

now in your adapter you can do this

SharedPreferences pref = PreferenceManager
        .getDefaultSharedPreferences(ctx);
String userObject = pref.getString(key, null);
