单击时会在 Leanback Guided Step Action 上显示密码

Question

我的 Leanback 应用程序中有一个 GuidedStepFragment 作为身份验证类型片段。

如何防止 "password" GuidedAction 在用户按下回车键或转到下一个 Guided Action 时显示键入的文本？

我面临的问题是密码在用户键入时隐藏，但在用户转到下一个 GuidedAction 时显示。

@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);
}

我已尝试重写 setupImeOptions 以在 EditText 上显式设置 TransformationMethod，但在用户转到下一个操作后仍然无法隐藏用户密码。

@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);
}

Answer 1

以下代码有效

GuidedAction.Builder(activity)
            .id(PASSWORD.toLong())
            .title("Password")
            .descriptionEditable(true)
            .descriptionInputType(InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD)
            .descriptionEditInputType(InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_VARIATION_PASSWORD)
            .build()
