Question

I need to call the setContentView(int) from my main Activity from another class which does not extends Activity.

In my custom class I’ve got the private Context context; var that is passed from the Activity in the Constructor but I can’t figure out how to acces the Activity methods using the context variable.

Answer 1

If your context is an instance of Activity class, simple class cast should work:

Activity a = (Activity) context;
a.setContentView(R.layout.your_layout);
