dynamically add array of buttons and reference those buttons by id in android

In code why don't you just declare a class level variable? Another common technique is to save references as tags or save whole bunch of references in the holder object and save that as a tag

Add new Array of numbers to Gridview after using OnclickItemListener

You could hold a reference to the list:

numbersArrayList = randomArray(arrayNumbers);
final ArrayAdapter<Integer> adapter = new ArrayAdapter<Integer>(this,
        android.R.layout.simple_list_item_1, numbersArrayList);

And then without changing the reference you can update the items in your OnItemClickListener:

numbersArrayList.clear();
List<Integer> newList = randomArray(arrayNumbers);
Collections.shuffle(newList);
numbersArrayList.addAll(newList);
adapter.notifyDataSetChanged();

Android UI - add buttons dynamically to Gridview

1) How to create a list view inside a main view, only using a half of the screen.

This is done by the weight attribute. A rough example for your sketch: The top wrapper (edittexts and buttons) has a weight of .45, the listview has a weight of .45 and the footer has a weight of .1. You can specify the weight-sum in the surrounding view; but default should be 1.

2) How to populate list view in grid manner (a row of two columns will repeat itself)

Well, with the GridView (the adapter API is the same) (:
