如何在操作栏选项卡中以编程方式更改选定的选项卡指示器颜色

Question

我有列表视图，每个列表项都有不同的颜色。 单击任何列表项后，我导航到一个活动，其动作栏包含一些选项卡。 现在，我必须将来自项目单击的颜色设置为选定选项卡的选项卡指示器颜色。 我尝试了以下链接，但没有运气

是否可以通过编程方式更改操作栏标签指示器

您可以更改所选标签的焦点

<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
      android:state_pressed="false"
      android:drawable="@drawable/tab_unselected" />
<item android:state_focused="false" android:state_selected="true"
      android:state_pressed="false"
      android:drawable="@drawable/tab_selected" />

<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
      android:state_pressed="false"
      android:drawable="@drawable/tab_unselected_focused" />
<item android:state_focused="true" android:state_selected="true"
      android:state_pressed="false"
      android:drawable="@drawable/tab_selected_focused" />

<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false"
      android:state_pressed="true"
      android:drawable="@drawable/tab_unselected_pressed" />
<item android:state_focused="false" android:state_selected="true"
    android:state_pressed="true"
    android:drawable="@drawable/tab_selected_pressed" />

<!-- Focused states (such as when focused with a d-pad or mouse hover) -->
<item android:state_focused="true" android:state_selected="false"
      android:state_pressed="true"
      android:drawable="@drawable/tab_unselected_pressed" />
