Constructor CustomKeyboard(LoginDialog, int, int) is undefined

Question

I'm attempting to implement a custom keyboard in my app and I need to use it during a login dialog prompt.

I've attempted to implement the example found here:

http://www.fampennings.nl/maarten/android/09keyboard/index.htm

However I'm getting an error in my code when I attempt to implement it on the line:

mCustomKeyboard= new CustomKeyboard(this, R.id.keyboardview, R.xml.hexkbd );

Stating that "The constructor CustomKeyboard(LoginDialog, int, int) is undefined LoginDialog.java"

I've tried changing the constructor from:

   public CustomKeyboard(Activity host, int viewid, int layoutid) {
mHostActivity= host;

to

 public CustomKeyboard(LoginDialog loginDialog, int viewid, int layoutid) {
        mHostActivity= loginDialog;

but it causes a domino effect of other issues in the code so I'm thinking there is a better way of implementing this constructor.

LoginDialog.java

public class LoginDialog extends DialogFragment implements
ActionCompletedListener {
    private View view;
    private String whichActivity = "";
    private TextView error;
    CustomKeyboard mCustomKeyboard;

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        AlertDialog.Builder builder = new AlertDialog.Builder(
        new ContextThemeWrapper(getActivity(), R.style.HoloDarkDialog));
        LayoutInflater inflater = getActivity().getLayoutInflater();
        view = inflater.inflate(R.layout.login, null);
        mCustomKeyboard = new CustomKeyboard(this, R.id.keyboardview,
                R.xml.hexkbd);

CustomKeyboard.java

  public CustomKeyboard(Activity host, int viewid, int layoutid) {
    mHostActivity= host;
    mKeyboardView= (KeyboardView)mHostActivity.findViewById(viewid);
    mKeyboardView.setKeyboard(new Keyboard(mHostActivity, layoutid));
    mKeyboardView.setPreviewEnabled(false); // NOTE Do not show the preview balloons
    mKeyboardView.setOnKeyboardActionListener(mOnKeyboardActionListener);
    // Hide the standard keyboard initially
    mHostActivity.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
}

P.S.

Any suggestions are GREATLY appreciated... and additional information/source can/will be provided promptly by request.

The problem here is that by supplying this at the constructor, you are pointing to the LoginDialog which was inherited from DialogFragment, which is subclass of Fragment, while constructor expects Activity or any of it's subclasses. I don't know the full code, but if you need to supply Activity to constructor, you can use HostingActivity.this. If you want to work with this constructor:

public CustomKeyboard(LoginDialog loginDialog, int viewid, int layoutid)

you can get hosting activity by calling loginDialog.getActivity() and you can get corresponding view with loginDialog.getView()
