如何更改ActionBar导航标签的颜色？
如何更改ActionBar导航标签的颜色？
提问于 2011-12-28 02:15:46
我在一个应用程序中有一个ActionBar，它嵌入了导航标签(而不是TabHost!)。默认情况下，选项卡显示为深灰色，所有选项卡下都有一条蓝色细线，所选选项卡上有一个蓝色标记。
要更改这些颜色，我应该覆盖哪些样式？

我没有更改标签本身，但我假设您可以使用styles.xml中的这些样式来进行更改……
<style name="Widget.Holo.TabWidget" parent="Widget.TabWidget">
<item name="android:tabStripLeft">@null</item>
<item name="android:tabStripRight">@null</item>
<item name="android:tabStripEnabled">false</item>
<item name="android:divider">?android:attr/dividerVertical</item>
<item name="android:showDividers">middle</item>
<item name="android:dividerPadding">8dip</item>
<item name="android:measureWithLargestChild">true</item>
<item name="android:tabLayout">@android:layout/tab_indicator_holo</item>
</style>使用tab_indicator_holo.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_holo" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_focused_holo" />
</selector>或者你也可以尝试
<style name="Widget.Holo.ActionBar.TabView" parent="Widget.ActionBar.TabView">
<item name="android:background">@drawable/tab_indicator_ab_holo</item>
<item name="android:paddingLeft">16dip</item>
<item name="android:paddingRight">16dip</item>
</style>和tab_indicator_ab_holo.xml
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@color/transparent" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/list_focused_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_holo" />
<!-- Pressed -->
<!-- Non focused states -->
<item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/list_pressed_holo_dark" />
<item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />
<!-- Focused states -->
<item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" />
<item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" />
</selector>最后，使用两个png-9可绘制文件：tab_selected_holo和tab_unselected_holo。它们看起来像你正在谈论的两条更粗和更细的蓝线。
或者你是说迷你小巴？
<style name="Widget.ActionBar.TabView" parent="Widget">
<item name="android:gravity">center_horizontal</item>
<item name="android:background">@drawable/minitab_lt</item>
<item name="android:paddingLeft">4dip</item>
<item name="android:paddingRight">4dip</item>
</style>在minitab_lt.xml中使用
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:state_selected="true"
android:drawable="@drawable/minitab_lt_press" />
<item android:state_selected="true"
android:drawable="@drawable/minitab_lt_selected" />
<item android:state_pressed="true"
android:drawable="@drawable/minitab_lt_unselected_press" />
<item android:drawable="@drawable/minitab_lt_unselected" />
</selector>如果您需要其他定义，只需在此处搜索TabWidget：https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml
然后像往常一样用所有需要的属性和绘图定义你自己的样式……
