Create getContentResolver () to work in class extending fragment class



I mean to use two snippets, first to display the contact list and the second to display the details of the contact that is selected in the top snippet.
The class I am using to extend the Fragment class does not allow me to use the method getContentResolver()

due to a context issue. Now I'm trying to find a contact in the same class that extends the Fragment class and uses it to display as a list and its details. After going through some old solution, I found a way to create a function and pass the context to it as a parameter, but the problem is that I don't need to call it from any other class that extends Activity. I want to do this from the same class extending the fragment.

How should I do it?

Any help would be much appreciated.

Try adding this code to your previous activity:

// a static variable to get a reference of our application context
public static Context contextOfApplication;
public static Context getContextOfApplication()
{
return contextOfApplication;
}

and in the same activity, in the onCreate method add this line:



 contextOfApplication = getApplicationContext();

In your snippet, you can access this using:

Context applicationContext = YourActivity.getContextOfApplication();
applicationContext.getContentResolver();

Getting app context with getter doesn't work. The equivalent of the above answer is



getActivity().getApplicationContext().getContentResolver().

I had a similar problem with a snippet, but I tried
