Android - SharedPreferences Error related to Context

I have a question about SharedPreferences. I have implemented them in a class called HashM.java. Starts something like this:

public void getPrefs (Context BaseContext) {

        SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(BaseContext);

I am trying to call it in my click listener this way:

HashM hash = new HashM();
hash.getPrefs();

But, I get an error:

getPrefs (Context) in HashM cannot be applied

Can someone point me to how I can fix this? thank you.

If your HashM class has more methods which need a specified context, consider to make a constructor for this class with a Context parameter, and assign it to a variable, like this:

class HashM
Context mContext;

public HashM  (Context context) {
mContext = context;
}

public void getPrefs () {
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(mContext);

And make a reference as

HashM hashM = new HashM(getActivity());

Adding to @Rohit5k2's answer, you can also use

HashM hash = new HashM(); 
hash.getPrefs(getActivity());

getPrefs(Context) expects context as a parameter. You need to pass the activity context inside it.

You can do it like this

HashM hash = new HashM();
hash.getPrefs(MyActivity.this); // MyActivity is the activity where you are putting this code
