切换键盘视图的代码Android Studio

Question

I am creating a custom Android keyboard at the moment. I have the letter page completed, but I do not know how to create a button that will switch to the symbols view. I want to click the 'Sym' button and switch the view to symbols. What methods should I be using etc?

You can specify your "Sym" key with code like

<Key android:codes="-2" android:keyLabel="Sym"/>

and make action to your keyboard.java using onKey method

            case Keyboard.KEYCODE_MODE_CHANGE:
            keyboard = new Keyboard(this, R.xml.symbols);
            kv.setKeyboard(keyboard);
            kv.setOnKeyboardActionListener(this);
            break;
