Hi have a strange issue, with swich and open keyboard

[MrD0llaro]

If the user use the swich I need to move the focus on edit text and open the keyboard.

this is the code

EditText pinView;
 com.rey.material.widget.Switch fingerprintSwitch;

protected void gestioneTouchID() {
    fingerprintSwitch.setOnCheckedChangeListener(new Switch.OnCheckedChangeListener() {
      @Override public void onCheckedChanged(Switch view, boolean checked) {
        if (view.isChecked()) {
          iconaImpronta.setImageResource(R.drawable.ic_impronta_attiva);
openKeyboardForPin();
        } else {
          iconaImpronta.setImageResource(R.drawable.ic_impronta_disabled);
          removeToken();
        }
      }
    });

private void openKeyboardForPin() {
    pinView.setFocusableInTouchMode(true);
    pinView.requestFocus();
    InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.showSoftInput(pinView, InputMethodManager.SHOW_IMPLICIT);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, InputMethodManager.HIDE_IMPLICIT_ONLY);
  }

but is impossible to open the keyboard.

the openKeyboardForPin workFine in other scenario.
