我的工具栏在backPressed时变得不可见或消失。仅当工具栏已折叠时才会出现这种情况。

原来我的代码还可以。 问题是由appcompat lib上的一些错误引起的。我刚刚将支持库更新到版本22.2.1,问题就消失了。
compile "com.android.support:appcompat-v7:22.2.1"
compile "com.android.support:support-annotations:22.2.1"
compile "com.android.support:design:22.2.1"
compile 'com.android.support:recyclerview-v7:22.2.1'
compile 'com.android.support:cardview-v7:22.2.1'

目前仅适用于设计支持库v22.2.1 https://code.google.com/p/android/issues/detail?id=183333
