我如何使整个显示滚动 [英] how do I make my whole display to be scrollable

问题描述

我正在为我的餐厅制作一个应用程序，当用户进入餐厅页面时，他或她将能够看到所有可选项目，如下图所示:

在这里您可以看到我突出显示了一部分，而该部分是Expandable listView.事实是，当我滚动可扩展列表时，我希望整个页面都向上滚动，而不仅是整个方向的可扩展列表都可以滚动.

这是我的XML代码:

 < LinearLayout xmlns:android =" http://schemas.android.com/apk/res/android"xmlns:app =" http://schemas.android.com/apk/res-autoxmlns:tools ="http://schemas.android.com/tools"android:layout_width =" match_parent"android:layout_height =" match_parent"android:fitsSystemWindows =" true"android:orientation ="vertical"工具:context =.UI_Activity.RestaurantDetail"< LinearLayoutandroid:layout_width =" match_parent"android:layout_height =" match_parent"android:orientation =" vertical">< LinearLayoutandroid:layout_width =" match_parent"android:layout_height =" wrap_content"android:orientation =水平">< ImageButtonandroid:id =" @ + id/RestaurantBackKey"android:layout_marginTop =" 10dp"android:layout_width =" 40dp"android:layout_marginStart =" 6dp"android:layout_height =" 30dp"android:gravity ="center"android:background =?attr/selectableItemBackground"app:srcCompat ="@ drawable/ic_back_key"android:textStyle =" bold"/>< TextViewandroid:layout_width =" match_parent"android:layout_height =" wrap_content"android:gravity ="center"android:padding ="5dp"android:textSize ="20sp";android:textStyle =" bold"android:layout_marginEnd =" 52dp"android:layout_marginTop =" 5dp"android:text =" @ string/app_name"/></LinearLayout>< LinearLayoutandroid:layout_width =" wrap_content"android:layout_height =" wrap_content"android:orientation =" vertical">< androidx.cardview.widget.CardViewandroid:layout_width =" match_parent"android:layout_height ="250dp"；android:layout_marginStart =" 8dp"android:layout_marginTop =" 5dp"android:layout_marginEnd =" 8dp"android:layout_marginBottom =" 8dp"app:cardCornerRadius ="13dp"< ImageViewandroid:id =" @ + id/RestaurantImage"android:layout_width =" match_parent"android:layout_height =" match_parent"android:scaleType =" centerCrop"/></androidx.cardview.widget.CardView>< TextViewandroid:id =" @ + id/RestaurantNameandroid:layout_width =" match_parent"android:layout_height =" wrap_content"android:gravity ="center"android:padding ="5dp"android:text =" RestaurantName"android:textSize ="20sp";android:textStyle =" bold"/>< TextViewandroid:id ="@@ id/RestaurantTheme"android:layout_width =" match_parent"android:layout_height =" wrap_content"android:gravity ="center"android:padding ="5dp"android:text ="这家商店是基于真实事物android:textSize =" 15sp"android:textStyle ="斜体"/>< RelativeLayoutandroid:layout_width =" match_parent"android:layout_height =" wrap_content"android:layout_marginTop =" 5dp"android:orientation =水平">< TextViewandroid:layout_width =" wrap_content"android:layout_height =" wrap_content"android:padding ="8dp"android:layout_marginStart =" 5dp"android:text ="要约"android:textSize =" 15sp"android:textStyle =" bold"/>< TextViewandroid:id ="@@ id/OfferAvailability"；android:layout_width =" wrap_content"android:layout_height =" wrap_content"android:layout_alignParentEnd =" true"android:layout_marginEnd =" 10dp"android:clickable =" true"android:focusable ="true"android:padding ="8dp"android:text ="没有报价％"android:textColor ="#9BA176"android:textSize =" 15sp"android:textStyle =" bold"/></RelativeLayout>< TextViewandroid:layout_width =" match_parent"android:layout_height =" wrap_content"android:text ="菜单项"android:gravity ="center"android:textSize =" 18sp"android:padding ="5dp"/></LinearLayout>< ExpandableListViewandroid:id =" @ + id/RestaurantItemList"android:layout_width =" match_parent"android:layout_height =" match_parent"android:footerDividersEnabled ="false"；android:headerDividersEnabled ="false"；android:smoothScrollbar =" false"/></LinearLayout> 

任何人都可以告诉我要进行哪些更改或布局，或者在现有代码中必须进行任何更新吗?

我想要的是，当我滚动可扩展列表视图时，我希望整个显示都随它一起滚动.

先谢谢您

解决方案

我能够通过为ExpandableListView创建自定义类来解决此问题.在进行了一些更改之后，终于可以实现我一直在寻找的结果，谢谢.

您可以参考以下链接:此处

I am making an App for my restaurant, there when the user enters the restaurant page, he or she will be able to see all the selectable Item here is the image below:

Here you can see that I have highlighted a portion and that portion is Expandable listView. The thing is that when I scroll the expandable list VIew I want the whole page to scroll up not just the Expandable List the whole page to be a scroll when I scroll in either direction.

here is my XML code:

        android:footerDividersEnabled="false"
        android:headerDividersEnabled="false"
        android:smoothScrollbar="false" />

</LinearLayout>

Can anyone tell me what changes to be made or which layout or is there any update That I have to do in my existing code?

What I want is that when I scroll the expandable list View I want the whole display to get scroll along with it.

Thank you in Advance

解决方案

I was able to solve it by making a custom class for ExpandableListView. Where I have made some changes and finally I was able to achieve the result I was looking for either way thank you.
