在CollapsingToolbarLayout中设置minHeight无效 [英] setting minHeight in CollapsingToolbarLayout not having any effect

问题描述

CollapsingToolbarLayout当前存在的主要问题是，无论我尝试什么，我的工具栏的minHeight属性都没有任何作用.

The main problem I've currently got with the CollapsingToolbarLayout is, that whatever I'm trying, the minHeight attribute of my Toolbar does not have any effect.

我想要的结果是: (CollapsingToolbarLayout具有一定的展开高度和一定的折叠高度(在示例中为180dp)，而标题折叠或停留在顶部)

My desired result would be this: (The CollapsingToolbarLayout with a certain expanded height and a certain collapsed height (in the example 180dp), while the title either collapses or stays on the top)

但是无论我做什么，标题有时都在中间，不会完全折叠，或者无论如何都会忽略minHeight.我试图通过Web上找到的各种方法设置AppBarLayout，CollapsingToolbarLayout，工具栏本身，任何内容等的minHeight，但是没有运气.

But whatever I do, the title sometimes is in the center, won't completely collapse or the minHeight is ignored anyway. I have tried to set the minHeight for either AppBarLayout, CollapsingToolbarLayout, the toolbar itself, any contents, etc. also with different approaches found on the web but with no luck.

这是基本的xml:

<android.support.design.widget.AppBarLayout
        android:id="@+id/app_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:fitsSystemWindows="true"
        android:minHeight="180dp">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fitsSystemWindows="true"
            app:contentScrim="@android:color/transparent"
            app:expandedTitleGravity="bottom"
            app:expandedTitleTextAppearance="@style/TextAppearence.App.ToolbarTitle"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            app:statusBarScrim="@android:color/transparent">

            <com.xxxxxx.custom.Banner
                android:id="@+id/parallax_image"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_gravity="center"
                android:adjustViewBounds="true"
                android:fitsSystemWindows="true"
                android:scaleType="centerCrop"
                android:src="@drawable/xxxxxxxx"
                app:layout_collapseMode="parallax"
                app:layout_collapseParallaxMultiplier="0.6"
                app:layout_scrollFlags="scroll" />

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                android:minHeight="180dp"
                app:layout_collapseMode="pin" />

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

我希望这足以解释我的问题. 感谢您的任何帮助，谢谢！

推荐答案

您可以将高度设置为180dp而不是使用minHeight，然后将TextView添加到工具栏中以用作标题.

You can set the height to 180dp instead of using minHeight, and then add a TextView into the toolbar to serve as the title.
