尝试编译安卓程序 Error retrieving parent for item: No resource found that matches the given name

其实软件就是 SS ，想学习安卓，看看这东西是怎么写的。

想预览一下 layout ，总是报错：
Rendering Problems Missing styles.
Is the correct theme chosen for this layout?
Use the Theme combo box above the layout to choose a different layout, or fix the theme style references.

NOTE: One or more layouts are missing the layout_width or layout_height attributes. These are required in most layouts.
Or: Automatically add all missing attributes
The following classes could not be found:

- android.support.v7.widget.Toolbar (Fix Build Path, Edit XML, Create Class)

Tip: Try to build the project.
Couldn't resolve resource @style/ThemeOverlay.AppCompat.Dark.ActionBar (3 similar errors not shown) Failed to find style 'switchStyle' in current theme (18 similar errors not shown) Exception raised during rendering: Color value '?android:attr/textColorSecondary' must start with # (Details) (2 similar errors not shown)

尝试 Make 也会出现类似的错误：
Error retrieving parent for item: No resource found that matches the given name 'TextAppearance.Widget.AppCompat.Toolbar.Title'.
Error retrieving parent for item: No resource found that matches the given name 'Theme.AppCompat.Light.NoActionBar'.
Error: No resource found that matches the given name: attr 'colorAccent'.
...后面还有十多个一样的错误

等等都是类似这样的问题，用的是 API 23 ， java1.8

查了一下，发现这个 AppCompat 是 API7 的东西， SDK 工具里面我也安装了 Android Support Library
~/Library/Android/sdk/extras/android/support/v7/ 里面也是有 appcompat

那么我怎么才能把它导进去呢？试了几种方法都依旧出错

谢谢
