Android - Change Actionbar Title Text Color

Question

I'm developing an app and I want to change the textcolor of the actionbar title. now, I defined a theme in my manifest:

<application
        android:theme="@style/AppTheme">
</application>

which is defined in styles.xml:

<style name="AppTheme" parent="android:style/Theme.Holo.Light">
        <item name="android:textViewStyle">@style/AppTheme.TextView</item>
        <item name="android:actionBarStyle">@style/AppTheme.ActionBarStyle</item>
    </style>

    <style name="AppTheme.ActionBarStyle" parent="@android:style/Widget.Holo.Light.ActionBar">
        <item name="android:titleTextStyle">@style/AppTheme.ActionBar.TitleTextStyle</item>
    </style>

    <style name="AppTheme.ActionBar.TitleTextStyle" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
        <item name="android:textColor">@color/themeapp</item>
    </style>

    <style name="AppTheme.TextView" parent="@android:style/Widget.TextView">
        <item name="android:textColor">#FFFFFF</item>
    </style>

this doesn't work but I don't get why. this should work according to this answer.neither the textview style is working.

what I am doing wrong?

Answer 1

Using SpannableString we can set Text Color of Actionbar title

SpannableString s = new SpannableString(title);
s.setSpan(new ForegroundColorSpan(Color.GREEN), 0, title.length(), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
getSupportActionBar().setTitle(s);

Answer 2

<style name="AppTheme" parent="android:style/Theme.Holo.Light">

<style name="AppTheme.TextView" parent="android:Widget.TextView">

You missed a symbol "@" here?

<style name="MyTheme" parent="@android:style/Theme.Holo.Light">

also

<style name="AppTheme.TextView" parent="@android:Widget.TextView">
