CollapsingToolbarLayout:
CollapsingToolbarLayout也是android.support:design包中的支持的控件,继承自FrameLayout.主要用于实现ToolBar的伸缩效果,而且必须为AppBarLayout的直接子View;
继承结构图如下:
java.lang.Object
↳ android.view.View
↳ android.view.ViewGroup
↳ android.widget.FrameLayout
↳ android.support.design.widget.CollapsingToolbarLayout
主要使用到的方法如下:
- setCollapsedTitleGravity
void setCollapsedTitleGravity（int gravity）
设置折叠标题和垂直重力的水平对齐方式，当折叠边界中有额外空间超出标题本身所需的空间时，将使用该对齐方式
相关的XML属性：
CollapsingToolbarLayout_collapsedTitleGravity
2.setExpandedTitleGravity
void setExpandedTitleGravity（int gravity）
设置展开标题和垂直重力的水平对齐方式，当扩展边界中有额外空间超出标题本身所需的空间时，将使用该对齐方式。
相关的XML属性：
CollapsingToolbarLayout_expandedTitleGravity
3.setExpandedTitleTextColor
void setExpandedTitleTextColor（ColorStateList colors）
设置展开标题的文本颜色。
4.setCollapsedTitleTextColor
void setCollapsedTitleTextColor（ColorStateList colors）
设置折叠标题的文本颜色。
5.setCollapsedTitleTypeface
void setCollapsedTitleTypeface（字体字体）
设置用于折叠标题的字体。
5.setExpandedTitleMarginBottom
void setExpandedTitleMarginBottom（int margin）
以像素为单位设置底部展开的标题边距。
相关的XML属性：
CollapsingToolbarLayout_expandedTitleMarginBottom
- 固定Toolbar
app:layout_collapseMode=“pin”
6.更多方法见文档
特别说明:
三剑客配合使用，可以做出一些很炫酷的UI效果.
但是前提必须满足:AppbarLayout 要作为CoordinatorLayout 的直接子View，而CollapsingToolbarLayout 要作为AppbarLayout 的直接子View ，否则，上面展示的效果将实现不了.
