以编程方式更改单个ActionBar菜单项的TextColor / Background

Question

Is there a way to change the Text color or background color of a single ActionBar menu item by code ?

To be more clear, only one item of the actionBar should have a different color, the rest of them should be the original color.

If so, how exactly can I achieve this. Thank you.

Answer 1

add this lines at styles.xml

<style name="AppTheme" parent="AppBaseTheme">
    <item name="android:actionBarStyle">@style/MyActionBar</item>
</style>

<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
    <item name="android:background">#de5188</item>
    <item name="android:titleTextStyle">@style/MyActionBarTitleText</item>
    <item name="android:subtitleTextStyle">@style/MyActionBarSubTitleText</item>
</style>

<style name="MyActionBarTitleText" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
    <item name="android:textColor">#ffffff</item>
    <item name="android:textStyle">bold</item>
</style>

<style name="MyActionBarSubTitleText" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
    <item name="android:textColor">#ffffff</item>
    <item name="android:textSize">10dp</item>
</style>

And change your manifasted as

 android:theme="@style/AppTheme"

I hope this one help to you :)

Background :

 ActionBar bar = getActionBar();
bar.setBackgroundDrawable(new ColorDrawable(Color.parseColor("#0000ff"))); //<-- Your Color

TextColor :

getActionBar()/* or getSupportActionBar() */.setTitle(Html.fromHtml("<font color=\"red\">" + getString(R.string.app_name) + "</font>"));

I think you can use both answer @user3515851 and mine.

It would be better if you used a custom Layout for action bar for some cases like this.

actionBar.showCustomView(true)// or similar to this.
actionBar.setCustomView(view)// you can inflate the view as you wish

so you can customise as it was a normal layout like RelativeLayout.

I hope this helps.
