MainActivity.java

public class KeyboardActivity extends AppCompatActivity {

    private KokoKeyboardView keyboard;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_keyboard);

        keyboard = findViewById(R.id.keyboardview);
        keyboard.registerEditText(KokoKeyboardView.INPUT_TYPE_QWERTY_NUM, findViewById(R.id.input_text));
        keyboard.registerEditText(KokoKeyboardView.INPUT_TYPE_QWERTY, findViewById(R.id.input_text_non_num));
    }

    @Override
    public void onBackPressed() {
        if (keyboard.isExpanded()) {
            keyboard.toggle();
        } else {
            super.onBackPressed();
        }
    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        keyboard.unregisterEditText(findViewById(R.id.input_text));
        keyboard.unregisterEditText(findViewById(R.id.input_text_non_num));
    }
}

Calling keyboard.registerEditText() enables the specific EditText to use the custom keyboard. The first argument determines the type of keypad that will be used. Currently the options supported are KokoKeyboardView.INPUT_TYPE_QWERTY and KokoKeyboardView.INPUT_TYPE_QWERTY_NUM . We have various key types like SquareKeyView for normal char entry and RectangularKeyView to handle special actions.

Coming Soon

Availability as system-wide Android Keyboard. This will be achieved using KeyInputMethodService implementaion of InputMethodService.
Support for more special char and special actions like delete select, forward delete, mode change e.t.c
Support for customized look i.e themes.
