错误:找不到符号变量abc_ic_ab_back_mtrl_am_alpha [英] error: cannot find symbol variable abc_ic_ab_back_mtrl_am_alpha

问题描述

我使用New > Fragment > Fragment (Blank)向我的Android Studio项目添加了一个片段.结果，当我尝试运行时，项目无法编译，因为它无法解析

I added a Fragment to my Android Studio project using New > Fragment > Fragment (Blank). As a result when I try to run, the project won't compile because it cannot resolve R.drawable.abc_ic_ab_back_mtrl_am_alpha in

toolbar.setNavigationIcon(R.drawable.abc_ic_ab_back_mtrl_am_alpha);

有什么办法解决这个问题吗?

Any ideas how to solve this?

我似乎也失去了对android:buttonTint

推荐答案

在23.2.0支持库中更改了资源名称.

The name of the resource was changed in the 23.2.0 support library.

修改 abc_ic_ab_back_mtrl_am_alpha 为 abc_ic_ab_back_material

在23.2.1中，该组件的名称改回了abc_ic_ab_back_mtrl_am_alpha

In 23.2.1 the name of the component was changed back to abc_ic_ab_back_mtrl_am_alpha

在24.0.0中，组件的名称更改为: abc_ic_ab_back_material

In 24.0.0 the name of the component was changed to: abc_ic_ab_back_material
