Android - How can I be able to get a View that has been added programmatically?

Question

I have the following problem. This is a little sketch of my layout (only the intereseted part):

<HorizontalScrollView
            android:id="@+id/horizontalScrollView"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:scrollbars="none"
             >

            <LinearLayout
                android:id="@+id/horizontalLayoutContainer"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="horizontal" >
            </LinearLayout>
</HorizontalScrollView>

Now I have added four buttons to the horizontalLayoutContainer ID layout. I want to be able to disable the buttons within the container, but of coarse I'm not :(( How can I get the views related to the Buttons that have been added dinamically? (I can't use the generateID on the buttons because it is available from API 17).

I have also tried to set the ID manually, starting from 0, and the result is that I'm able to catch the one with ID = 0 but not the others :(( Please help

Thanks

EDIT: ViewGroup mLayout = (ViewGroup) ((FragmentActivity) mContext).findViewById(rootLayoutID);

                    if(mLayout!=null){
                        for(int i = 0; i <  mLayout.getChildCount(); i++)
                        {
                            View view = mLayout.getChildAt(i);

                            if(!(view instanceof Button))
                                setViewsEnabled(mContext, view.getId(), enable);
                            else{
                                Log.debug(tag, "I'm a button with ID: "+ view.getId());
                                view.setEnabled(enable);
                                view.setClickable(enable);
                            }
                            view.setEnabled(enable);
                        }
                        mLayout.setEnabled(enable);
                    }
                }

With this portion of code I'm able to disable everything into my layout except for the buttons. As you can see I've also created a log that is printed 4 times (exactly the number of the button) but with ID = 0;

SOLVED: I've found a solution by assign programmatically (incrementally starting from 0) an ID and then making an if/else as shown below in order to recognize the right activity in which buttons are defined:

             /*
              * Se l'istanza e' MainActivity disabilito/abilito manualmente i bottoni
               */
                        if(mContext.getClass() == MainActivity.class){
                            ViewGroup horizontalScrollViewViewGroup = (ViewGroup)
                                    ((FragmentActivity) mContext).findViewById(R.id.horizontalLayoutContainer); 

                            if(horizontalScrollViewViewGroup!=null){
                                Log.debug(tag, "Buttons Number: "+horizontalScrollViewViewGroup.getChildCount());

                                for(int i = 0; i < horizontalScrollViewViewGroup.getChildCount(); i++){
                                    View view = ((FragmentActivity) mContext).findViewById(i);
                                    if(view!=null){
                                        view.setClickable(enable);
                                        view.setEnabled(enable);
                                    }
                                }
                            }
                        }

Whenever you create dynamic view you can assign an id to that view as

final int  ID=1001;
Button btn=new Button (this);
btn.setId(ID);

and get the view using

findviewbyid(ID) ;
