如何在 android 中更改部分操作栏的颜色

how to change color of part of actionbar in android

我的操作栏标题是 2 个词,我想为每个词使用 2 种颜色,如下图所示:

现在我正在使用这些代码来更改文本颜色:

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <item name="android:actionBarSize">45dp</item>
        <item name="actionBarSize">45dp</item>


        <item name="android:actionBarStyle">@style/MyActionBar</item>
        <item name="actionBarStyle">@style/MyActionBar</item>
         <item name="android:windowActionBarOverlay">true</item>
    </style>


    <style name="MyActionBar" parent="@style/Widget.AppCompat.Light.ActionBar">
        <item name="android:background">@color/actionbar</item>
        <item name="background">@color/actionbar</item>
        <item name="android:titleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
        <item name="android:subtitleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
        <item name="titleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
        <item name="subtitleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>
     </style>
<style name="MyTheme.ActionBar.TitleTextStyle" parent="@android:style/TextAppearance">
        <item name="android:textColor">@color/white</item>
        <item name="android:textSize">15sp</item>
</style>

但是这些代码改变了两个字的颜色,那我该怎么做呢?

为您的字幕创建一个单独的样式。 在底部添加:

<style name="MyTheme.ActionBar.SubTitleTextStyle" parent="android:style/TextAppearance">
    <item name="android:textColor">@color/black</item>
    <item name="android:textSize">12sp</item>
</style>

然后改变

<item name="@android:subtitleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>

<item name="subtitleTextStyle">@style/MyTheme.ActionBar.TitleTextStyle</item>

<item name="android:subtitleTextStyle">@style/MyTheme.ActionBar.SubTitleTextStyle</item>

<item name="subtitleTextStyle">@style/MyTheme.ActionBar.SubTitleTextStyle</item>

尝试使用 spannable

    String part1 = "Actionbar ";
    String part2 = "TITLE";
    SpannableString s = new SpannableString(part1 + part2);
    s.setSpan(new ForegroundColorSpan(Color.RED), part1.length(), part1.length()+part2.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);

// Update the action bar title with the spannable instance
    getActionBar().setTitle(s);

把它放在你的 oncreate()

String text = "<font color='#F44336'>Your</font><font color='#FF9800'>Title</font>";

        getSupportActionBar().setTitle(Html.fromHtml(text));
