Why am I getting "The method getContext() is undefined for the type MainActivity"?

My MainActivity extends activity and I use getContext() in another class that has a instance of MainActivity passed in and it works fine there, my code:

convertView = LayoutInflater.from(parent.getContext())
                            .inflate(R.layout.nowview, parent, false);

Class constructor:

public PictureCard(String url, String title, int index,
                                             int pos, MainActivity parent)
{
    this.parent = parent;
    // ...
}

How I call the class 

Card newCard = new PictureCard(links.get(index) , titles.get(index),
                                                  index, position, parent);

(Parent is passed in as this from the MainActivity class)

Have you tried using getApplicationContext() instead of getContext()?

These links might help:

getApplication() vs. getApplicationContext()

Difference between getContext() , getApplicationContext() , getBaseContext() and "this"

If MainActivty extends Activty, then just use parent as the context:

convertView = LayoutInflater.from(parent)
                        .inflate(R.layout.nowview, parent, false);

Also, I suspect that you're passing the wrong instance here:

Card newCard = new PictureCard(links.get(index) , titles.get(index),
                                              index, position, parent);
                                                               ^^^^^^

it should be this, or MainActivty.this if it's within an inner class.

Instead of passing MainActivity you can pass context as parameter lik this

public PictureCard(String url, String title, int index, int pos, Context parent)

and call like

Card newCard = new PictureCard(links.get(index) , titles.get(index), index, position, MainActivity.this);
