Answer 1

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" />
