目前正在开发一款应用程序,我需要在“折叠”工具栏的右下角添加“共享”和“添加”按钮(用于视差效果).
这可能隐藏在滚动或可能坐在Actionbar上.添加了我想要实现的图像.目前还不知道如何做到这一点(尝试使用锚点的浮动操作按钮,但失败了).
这应该是这样的：
这是代码：
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="@+id/htab_maincontent"
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="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="@+id/htab_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/htab_collapse_toolbar"
android:layout_width="match_parent"
android:layout_height="256dp"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed|snap">
<ImageView
android:id="@+id/htab_header"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/header"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="@+id/htab_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:gravity="top"
app:layout_collapseMode="pin"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
app:titleMarginTop="13dp"/>
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="@+id/htab_tabs"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:layout_gravity="bottom"
android:background="@color/colorPrimary"
app:tabIndicatorHeight="@dimen/tabIndicatorHeight"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/htab_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
解决方法
如果您在CollapsingToolbarLayout中使用它,您可以这样做：
<android.support.design.widget.CollapsingToolbarLayout
android:id="@+id/toolbarCollapse"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="190dp"
android:background="@android:color/darker_gray"
android:minHeight="190dp"
android:src="@drawable/ic_email"
app:layout_collapseMode="parallax"
android:id="@+id/imageView8" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fabmain"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:src="@drawable/ic_add"
app:backgroundTint="@color/ColorAccent"
app:borderWidth="0dp"
app:fabSize="mini"
app:layout_anchor="@id/app_bar_layout"
app:layout_anchorGravity="bottom|end"
android:layout_marginLeft="16dp"
android:layout_marginRight="16dp"
android:layout_alignTop="@+id/fabmain2"
android:layout_toStartOf="@+id/fabmain2"
android:layout_marginEnd="20dp" />
<android.support.design.widget.FloatingActionButton
android:id="@+id/fabmain2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_marginLeft="16dp"
android:src="@drawable/ic_add"
app:backgroundTint="@color/ColorAccent"
app:borderWidth="0dp"
app:fabSize="mini"
app:layout_anchor="@id/app_bar_layout"
app:layout_anchorGravity="bottom|end"
android:layout_marginRight="16dp"
android:layout_marginEnd="23dp"
android:layout_alignBottom="@+id/imageView8"
android:layout_alignParentEnd="true"
android:layout_marginBottom="29dp" />
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?actionBarSize"
app:layout_collapseMode="pin" />
</RelativeLayout>
</android.support.design.widget.CollapsingToolbarLayout>
另外,根据Google Material Design,我不认为这是两个按钮的标准方式/好方法！
另外,这是我的想法(标准方式)：
您可以在操作栏上添加带有该图标的共享操作,然后像这样使用一个FloatingActionButton：

或者我自己这样做：
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:card_view="http://schemas.android.com/tools"

android:layout_height="match_parent"

<!--Your content-->
</android.support.v4.widget.NestedScrollView>
