you should use List at place of string array, List is dynamic growing array so you can easily add and remove items from List as below:

List<String> list = new ArrayList<String>();
if(button clicked)
{
   list.add(editText.getText().toString());
}

or if you are bound to use array of string in any case then follow "Kay" solution as well in that case you need to increment in item index in array before adding item into array.

Try Array List. use the following code in your main java 

final ArrayList<String> list = new ArrayList<String>();

Button button= (Button) findViewById(R.id.buttonId);
final EditText editText = (EditText) findViewById(R.id.editTextId)
button.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        list.add(editText.getText().toString());
    }
});

// to get i th element
int i=0;
Log.d("value", list.get(i));

Try:

...
int[] arr = new int[];

//listener
onclick()
  {
    arr = arr.addElement(arr,Integer.parseInt(et.getText().toString()));
  }

 }//oncreate end

static int[] addElement(int[] a, int e) {
a  = Arrays.copyOf(a, a.length + 1);
a[a.length - 1] = e;
return a;
}
