How can you make a custom keyboard in Android?

Question

I want to make a custom keyboard. I don\'t know how to do it using XML and Java. The following picture is a model of the keyboard I want to make. It only needs numbers.

Answer 1

Use KeyboardView:

KeyboardView kbd = new KeyboardView(context);
kbd.setKeyboard(new Keyboard(this, R.xml.custom));

kbd.setOnKeyboardActionListener(new OnKeyboardActionListener() {
    ....
}

now you have kbd which is a normal view.

The nice thing about this is that R.xml.custom refers to /res/xml/custom.xml, which defines in xml the layout of the keyboard. For more information on this file, look here: Keyboard, Keyboard.Row, Keyboard.Key.
