[英]Android Bottom Sheet Is not Reacting To Touches and doesn't Scroll
所以我有一个问题:我向我创建的FrameLayout
视图中添加了一个layout_behaviour为BottomSheetBehavior
的LinearLayout
,并在我的Activities
上方添加了它,但是我的底部工作表不可滚动,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:
<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/rich_media_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
. . . . . .
<LinearLayout
android:id="@+id/cue_point_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="16dp"
android:paddingBottom="16dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:id="@+id/cue_points_recycler_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:layout_marginTop="32dp"
android:layout_marginEnd="8dp" />
. . . . . .
</LinearLayout>
使用CoordinatorLayout
作为父布局。
<?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"?>
