Question

如何在 CollapsingToolbarLayout 中制作多行标题，例如.. 微信

我的XML文件

<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:background="@color/white"
    android:fitsSystemWindows="true">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/detail_backdrop_height"
        android:fitsSystemWindows="true"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">


        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginEnd="16dp"
            app:expandedTitleMarginStart="16dp"
            app:expandedTitleTextAppearance="@style/HeaderTitleStyle"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">


                    <ImageView
                        android:id="@+id/cover_image"
                        android:layout_width="match_parent"                             android:layout_height="@dimen/detail_backdrop_height"
                        android:background="@color/white"
                        android:fitsSystemWindows="true"
                        android:scaleType="fitXY"
                        android:src="@drawable/default_clg_image"
                        app:layout_collapseMode="parallax" />


            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:layout_collapseMode="pin"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

        </android.support.design.widget.CollapsingToolbarLayout>
    </android.support.design.widget.AppBarLayout>
</android.support.design.widget.CoordinatorLayout>

expandedTitleTextAppearance

app:expandedTitleTextAppearance="@style/HeaderTitleStyle"

这是我的style.xml

<style name="HeaderTitleStyle" parent="@android:style/TextAppearance">
    <item name="android:textColor">#FFFFFF</item>
    <item name="android:textSize">20sp</item>
    <item name="android:singleLine">false</item>
</style>

我找到了一个很棒的库，名为 multiline-collapsingtoolbar，它为您提供了一个可以处理多行标题的自定义折叠工具栏。

Usage

The library's public API is identical to the version from the support library, so you can use it as a drop-in replacement.

As the Design Support Library, it should be compatible with API 7 (Android 2.1) and above.

XML layout example:
<android.support.design.widget.AppBarLayout
        android:layout_height="192dp"
        android:layout_width="match_parent">
    <net.opacapp.multilinecollapsingtoolbar.CollapsingToolbarLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">
        <android.support.v7.widget.Toolbar
                android:layout_height="?attr/actionBarSize"
                android:layout_width="match_parent"
                app:layout_collapseMode="pin"/>
    </net.opacapp.multilinecollapsingtoolbar.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
You can find a simple demo application in the demo module.

一种更简单的方法是将自定义布局添加到折叠工具栏并在折叠时将其固定，这可能是最终输出：
