美好的一天，你能帮帮我吗？在模拟器上编译/运行我的代码时出现此错误。这是我用来制作的示例教程。我使用了 min Target API - 15 并编译了最新的 gradle
'com.android.support:design:23.0.0'
http://www.android4devs.com/2015/06/navigation-view-material-design-support.html
代码错误：
AndroidRuntime：java.lang.RuntimeException：无法启动活动 ComponentInfo{com.eccp.projects.ecosavers.ecosavers/com.eccp.projects.ecosavers.ecosavers.activities.MainActivity}：android.view.InflateException：二进制 XML 文件行# 29：二进制 XML 文件第 29 行：错误膨胀类 android.support.design.widget.NavigationView 12-29 06:43:39.409 3448-3448/com.eccp.projects.ecosavers.ecosavers E/AndroidRuntime：在 android.app .ActivityThread.performLaunchActivity(ActivityThread.java:2416)
