How to change keyboard layout in onSwipe method?

Question

I would like to know how to change keyboard layout in onSwipe method.
I have qwerty.xml with letters, but I need numbers and symbols.
These two groups of characters are in numeric.xml.
The numeric.xml will be show and qwerty.xml will be hidden when I swipe left or right.

If you need any part of my code please ask.

You need to change the layout on your keyboard object in your InputManagerService. Then you need to invalidate all keys to get the keyboard to be redrawn. Like so:

 public class MyKeyboard extends InputMethodService implements KeyboardView.OnKeyboardActionListener
 {

    private KeyboardView myKeyboardView;
    private Keyboard myKeyboard;

    public View onCreateInputView()
    {

       viewOfKeyboard = (KeyboardView)getLayoutInflater().inflate(R.layout.keyboard1, null);
       theKeyboardLayout = new Keyboard(this, R.xml.keyboardlayout);
       viewOfKeyboard.setKeyboard(theKeyboardLayout);
       viewOfKeyboard.setOnKeyboardActionListener(this);
       return myKeyboardView;
    }

    public void swipeRight()
    {
       if(isQwerty)
       {
         myKeyboard = new Keyboard(this, R.xml.numeric);
         //Creates a new keyboard object.
         myKeyboardView.setKeyboard(myKeyboard);
         //Assigns the new keyboard object to the keyboard view
         myKeyboardView.invalidateAllKeys();
         //Makes android redraw the keyboard view, with the new layout.
         isqwerty = false;
       }
       else
       {
         myKeyboard = new Keyboard(this, R.xml.qwerty); 
         myKeyboardView.setKeyboard(myKeyboard);
         myKeyboardView.invalidateAllKeys();
         isqwerty = true;
       }

       //.........the rest of MyKeyboard's methods     

    }
