如何在操作欄選項卡中以編程方式更改選定的選項卡指示器顏色

Question

我有列表視圖，每個列表項都有不同的顏色。 單擊任何列表項后，我導航到一個活動，其動作欄包含一些選項卡。 現在，我必須將來自項目單擊的顏色設置為選定選項卡的選項卡指示器顏色。 我嘗試了以下鏈接，但沒有運氣

是否可以通過編程方式更改操作欄標簽指示器

Answer 1

您可以更改所選標簽的焦點

<!-- 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 -->
