使用CoordinatorLayout、AppBarLayout、CollapsingToolbarLayout、FloatingActionButton制作连动布局。

Android Studio添加依赖：

compile 'com.android.support:design:25.3.1'

1. 主题使用NoActionBar。

    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"><!-- Customize your theme here. --><item name="colorPrimary">@color/colorPrimary</item><item name="colorPrimaryDark">@color/colorPrimaryDark</item><item name="colorAccent">@color/colorAccent</item></style>
```2. 主布局xml
```
