我在CoordinatorLayout中使用CollapsingToolbarLayout作为我的底片的布局。布局看起来像这样 -
<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/bottomSheet"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/darkBackgroundMainTranslucent"
app:behavior_hideable="true"
app:layout_behavior="@string/bottom_sheet_behavior">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="@dimen/detail_backdrop_height"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
android:fitsSystemWindows="true"
app:contentScrim="@color/colorScrim"
app:expandedTitleMarginStart="48dp"
app:expandedTitleMarginEnd="64dp">
<ImageView
android:id="@+id/backdrop"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:fitsSystemWindows="true"
android:contentDescription="@string/poster_string"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="@+id/bottomsheet_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay"
app:layout_collapseMode="pin" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
android:id="@+id/nestedScrollView">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:paddingTop="24dp">
<android.support.v7.widget.CardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/card_margin">
<LinearLayout
style="@style/Widget.CardContent"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Title"
android:textAppearance="@style/TextAppearance.AppCompat.Title" />
<TextView
android:id="@+id/bottomsheet_title"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textIsSelectable="true"/>
</LinearLayout>
</android.support.v7.widget.CardView>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
我想知道是否可以在CollapsingToolbarLayout中自定义工具栏以添加向上按钮并设置其标题而不将该工具栏设置为supportactionbar。
答案 0 :(得分:0)
您可以通过xml将图标/图像/按钮放在工具栏中,如下所示:
<android.support.v7.widget.Toolbar
android:id="@+id/bottomsheet_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="@style/AppTheme.PopupOverlay"
app:layout_collapseMode="pin">
<ImageButton
... your usual crud height/width ...
android:id="@+id/contact_detail_edit/>
<TextView />
</android.support.v7.widget.Toolbar>
然后通过工具栏访问它们,如下所示:
Toolbar bottomSheetToolbar = (Toolbar) bottomSheetLayout.findViewById(R.id.bottomsheet_toolbar);
ImageButton contact_detail_edit = (ImageButton)bottomSheetToolbar.findViewById(R.id.contact_detail_edit);
ImageButton contact_detail_favorite = (ImageButton)bottomSheetToolbar.findViewById(R.id.contact_detail_favorite);
