android - DialogFragment and force to show keyboard

I have a problem with my DialogFragment. So to create my view, I use the method described on the android blog. Here is my DialogFragment

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    final View myLayout = inflater.inflate(R.layout.dialog_connect, null);

    edit = (EditText) myLayout.findViewById(R.id.password_edit);
    edit.requestFocus();
    getDialog().getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE);

    return myLayout;
}

If I use onCreateView(), it works but I would like create an AlterDialog and to do this, I have the following code :

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    // Inflate and set the layout for the dialog
    // Pass null as the parent view because its going in the dialog layout
    builder
           .setPositiveButton(R.string.ok, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                    callback.onYesConnectClick(edit.getText().toString());
                }
            })
            .setNegativeButton(R.string.refuse, new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int id) {
                    callback.onNoConnectClick();
                }
            });

    return builder.create();
}

If I comment the code from onCreateView(), the app works but I can't force the keyboard to be shown and if I uncomment onCreateView(), I get a crash. Here is the stack trace :

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test/com.test.ProfileActivity_}: android.util.AndroidRuntimeException:     requestFeature() must be called before adding content

AndroidRuntime at dalvik.system.NativeStart.main(Native Method)
AndroidRuntime Caused by: android.util.AndroidRuntimeException: requestFeature() must be called before adding content

So my question ==> Can I use the AlertDialog and show the keyboard when the dialog appears ?

override onActivityCreated in your dialogfragment and put getDialog().getWindow().setSoftInputMode(LayoutParams.SOFT_INPUT_STATE_VISIBLE); in there
