Delete Sharedpreferences On Button Click

I'm a beginner to android. I have passed a sharedpreferences to intent activity. I want to remove it on button click by user. How can I execute that in code? I tried different way

Solution 1:

Retrieve a SharedPreferences object for accessing preferences that are private to this activity.

SharedPreferences preferences = getSharedPreferences("YOUR PREF", Context.MODE_PRIVATE);

SharedPreferences.Editor editor = preferences.edit();
editor.clear().apply(); //remove all//OR

editor.remove("KEY").apply(); //remove by key

use with click

button.setOnClickListener(newView.OnClickListener() {
    @OverridepublicvoidonClick(View view) {
         editor.remove("KEY").apply(); //remove by key
    }
});

Solution 2:

SharedPreference.Editorpref= context.getSharedPreferences("A_PREFS_FILE", 0).edit();
pref.clear();
pref.commit();
