我知道这已经被问过了,但是即使我检查了答案,也没有找到解决我特定问题的方法:
我创建了一个预期可以用作 Bottom Sheet 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,我尝试通过以下方式获得引用:
View tview = findViewById(R.id.btmsht);
btmsht = BottomSheetBehavior.from(tview);
我得到了错误:
java.lang.IllegalArgumentException: The view is not associated with BottomSheetBehavior

不重复,因为我的未嵌套并且是Coordinator Layout的直接子代
最佳答案
我已经解决了,如果其他人也有同样的问题,我想发布答案,当您导入包含BottomSheet的布局时,您不得包含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"/>
