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

Question

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)

it will be helpful if you post the method signature and method call of that class — stinepike, May 18 '13 at 05:47

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

These links might help:

getApplication() vs. getApplicationContext()

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

Same issue "The method getActivityContext() is undefined for the type MainActivity" – Osman May 18 '13 at 05:50
all forms of getcontext result in some kind of error, weird this is i run the same code in another class with the same pass in and declaration of parent, and it works? – Osman May 18 '13 at 05:59

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);

I think i will try that, I am just baffled to why what I am doing is working in one class and not another – Osman May 18 '13 at 05:59

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.

then I get "The method inflate(int, ViewGroup, boolean) in the type LayoutInflater is not applicable for the arguments (int, MainActivity, boolean)" – Osman May 18 '13 at 05:54
sorry I realized I misspoke I call this class from a class that is called by MainActivity, but still why would eclipse give me this error, I created the var correctly – Osman May 18 '13 at 05:56
