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 > 在我的 Android Studio 项目中添加了一个 Fragment片段 >片段(空白).结果当我尝试运行时，该项目将无法编译，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);

任何想法如何解决这个问题?

Any ideas how to solve this?

看来我也无法访问 android:buttonTint

推荐答案

资源名称已在 23.2.0 支持库中更改.

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

修改 abc_ic_ab_back_mtrl_am_alpha 到 abc_ic_ab_back_material

在 23.2.1 组件的名称改回 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
