java.lang.IllegalArgumentException: 该视图未与 BottomSheetBehavior 关联

Question

我知道之前有人问过这个问题，但即使我检查了答案，我也没有找到解决我的具体问题的方法：

我创建了一个预期用作底页的布局：

<android.support.constraint.ConstraintLayout 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:id="@+id/btmsht"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior"
android:orientation="vertical"
android:layout_height= "300dp"
android:layout_width="match_parent"
tools:showIn="@layout/activity_principal">

我在协调器布局中使用它：

<include layout="@layout/btmsht_principal" android:layout_width="match_parent"
    android:layout_height="match_parent"/>

但是当我尝试通过以下方式获取参考时：

View tview = findViewById(R.id.btmsht);
    btmsht = BottomSheetBehavior.from(tview);

我收到错误：

没有重复，因为我的没有嵌套并且是 Coordinator Layout 的直接子项

Answer 1

我已经解决了，我想 post 答案以防其他人遇到同样的问题，当您导入包含 BottomSheet 的布局时，您不能包含 layout_width 和layout_height:

<include layout="@layout/btmsht_principal"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

所以它必须是：

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

Answer 2

CoordinatorLayout 总是需要一个直接关联的子项，然后只有它才能工作，否则它将通过错误 "The view is not associated with BottomSheetBehavior"。在下面的 .xml 文件中，第二个相对布局是 CoordinatorLayout 的直接子级，即底部 sheet。在标签中我们可以添加 android:layout_width 和 android:layout_height.

<?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"
    android:id="@+id/main_content"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/rooms_background_txt"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <include
            android:id="@+id/toolbar_listing"
            layout="@layout/actionbar_room_selection"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </RelativeLayout>

    <RelativeLayout
        android:id="@+id/bottom_sheet"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/color_white"
        android:gravity="center"
        app:layout_behavior="@string/bottom_sheet_behavior">

        <TextView
            android:id="@+id/text_view"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
    </RelativeLayout>
</android.support.design.widget.CoordinatorLayout>

Answer 3

当我遇到这个问题时，上面的解决方案都没有解决。我发现我必须在<include>标签上复制app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"，如下：

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

    <include
        android:id="@+id/ll_poi_view"
        layout="@layout/ll_poi_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

这里是layout/ll_poi_view:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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="wrap_content"
    app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">

    <TextView
        android:id="@+id/headerTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:text="This area is for header content"
        android:textSize="24sp"
        android:textStyle="bold"
        app:layout_constraintBottom_toTopOf="@+id/poi_content_scrollview"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="0.5"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <androidx.core.widget.NestedScrollView
        android:id="@+id/poi_content_scrollview"
        android:layout_width="395dp"
        android:layout_height="match_parent"
        android:layout_marginStart="8dp"
        android:layout_marginEnd="8dp"
        android:fillViewport="true"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/headerTextView">

        <include
            android:id="@+id/poi_content"
            layout="@layout/ll_poi_view_scrollable_content"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

    </androidx.core.widget.NestedScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>

Answer 4

底部sheet主要内容使用：

app:layout_behavior="android.support.design.widget.BottomSheetBehavior"

在 Main activity 中与 include 布局一起使用 app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"

您的问题已解决
