Question

所以我有一个问题：我在我创建的LinearLayout的{{1}}视图中添加了一个layout_behaviour为BottomSheetBehavior的{{1}}，但在我的底部FrameLayout是不可滚动的，我只能以编程方式更改其状态，但触摸不会做出反应。您认为可能是什么问题？

这是我的xml：

Activities

Answer 1

使用CoordinatorLayout作为父级布局。

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <include layout="@layout/bottom_sheet" />
</android.support.design.widget.CoordinatorLayout>

bottom_sheet-

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/bottom_card"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    app:behavior_hideable="false"
    app:behavior_peekHeight="204dp"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    .......

</LinearLayout>

您必须使用CoordinatorLayout作为根布局

activity_main-

    <?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#f7f7f7">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="attr/actionBarSize"
            android:background="attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />


    </android.support.design.widget.AppBarLayout>

    <include layout="@layout/content_main" />

    <!-- Adding bottom sheet after main content -->
    <include layout="@layout/bottom_sheet" />

</android.support.design.widget.CoordinatorLayout>

bottom_sheet-

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/bottom_sheet"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#fff"
    android:orientation="vertical"
    android:padding="@dimen/activity_margin"
    app:behavior_hideable="true"
    app:behavior_peekHeight="56dp"
    app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        android:layout_gravity="center_vertical"
        android:weightSum="3">

        <TextView
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginBottom="@dimen/activity_margin"
            android:layout_weight="2"
            android:text="Order Details"
            android:textSize="18dp"
            android:textStyle="bold" />

        <TextView
            android:layout_width="0dp"
            android:gravity="right"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            android:textStyle="bold"
            android:textSize="15dp"
            android:text="₹475.00"></TextView>
    </LinearLayout>


    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Chicken Fried Rice 1x1" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Chiken Tikka 1x2" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="@dimen/activity_margin"
        android:text="Delivery Address"
        android:textStyle="bold" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Rohini delhi-42" />

    <Button
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="30dp"
        android:background="#000"
        android:foreground="?attr/selectableItemBackground"
        android:text="PROCEED PAYMENT"
        android:textColor="#fff" />

</LinearLayout>
