单击后,密码将显示在Leanback引导的步骤操作上

我的leanback应用程序中有一个GuidedStepFragment作为身份验证类型的片段。

当用户按enter键或进入下一个引导操作时,如何防止“密码”引导操作显示键入的文本?

我面临的问题是,当用户输入密码时,密码是隐藏的, 但当用户浏览下一个指南时会显示 .

@Override
public void onCreateActions(@NonNull List<GuidedAction> actions, Bundle savedInstanceState) {
    GuidedAction action;
    if (getArguments() != null) {
        type = getArguments().getInt(ARG_TYPE);
    }
    if (type == TYPE_EMAIL) {
        action = new GuidedAction.Builder(getActivity())
                .id(ActionConstants.ACTION_INPUT_EMAIL)
                .editable(true)
                .description(getString(R.string.email_address_hint))
                .editInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS)
                .build();
    } else {
        action = new GuidedAction.Builder(getActivity())
                .id(ActionConstants.ACTION_INPUT_PASS)
                .editable(true)
                .description(getString(R.string.password))
                .editInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD)
                .build();
    }
    actions.add(action);
    action = new GuidedAction.Builder(getActivity())
            .id(ActionConstants.ACTION_CONTINUE)
            .title(R.string.next)
            .hasNext(true) // Shows the small arrow indicating there's something next...
            .build();
    actions.add(action);
}

我已经尝试覆盖setupImeOptions,在EditText上显式设置TransformationMethod,但在用户执行下一个操作后,这仍然无法隐藏用户的密码。

@Override
protected void setupImeOptions(ViewHolder vh, GuidedAction action) {
    switch ((int) action.getId()) {
        case ActionConstants.ACTION_INPUT_PASS :
            vh.getEditableDescriptionView().setTransformationMethod(new PasswordTransformationMethod());
            vh.getEditableTitleView().setTransformationMethod(new PasswordTransformationMethod());
            break;
    }
    super.setupImeOptions(vh, action);
}
