Question

我想让操作栏变红并且不起作用。它启动应用程序然后立即说＆＃34;不幸的是，Action Bar已停止＆＃34;我可以快速看到该应用程序并阅读。我找了几个小时，互联网上什么都没有出现。有人可以提供帮助，因为我不熟悉编码吗？

Answer 1

使用以下代码

ActionBar action_bar = getActionBar();
action_bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#FF0000")));

从

改变你的风格

<!--
    Base application theme, dependent on API level. This theme is replaced
    by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
-->
<style name="AppBaseTheme" parent="Theme.AppCompat.Light">
    <!--
        Theme customizations available in newer API levels can go in
        res/values-vXX/styles.xml, while customizations related to
        backward-compatibility can go here.
    -->
</style>

<!-- Application theme. -->
<style name="CustomActionBarTheme" parent="AppBaseTheme">
    <!-- All customizations that are NOT specific to a particular API-level can go here. -->
</style>

Answer 2

试试这个

inherit

并在AppTheme上添加此应用：

<style name="ActionBar.Solid.Example" parent="@android:style/Widget.Holo.Light.ActionBar.Solid">
        <item name="android:background">Your color you want or drawable</item>
        <item name="android:backgroundStacked">Your color you want or drawable</item>
        <item name="android:backgroundSplit">Your color you want or drawable</item>
</style>
