Answer 1

When you create the Non Activity class in your Activity, pass the context to its constructor:

NonActivityClass nonActivityClass = new  NonActivityClass(this);

Non Activity constructor:

Context mContext;
public NonActivityClass(Context context){
    mContext = context;
}

then use:

new AlertDialog.Builder(mContext)... in the Non Activity class
