i've got a small question about the ActionBar
in Android.
I am using Xamarin Studio to make an application and i would like to change the color of the ActionBar. I've looked far and wide for a way to change the color but this is the only thing that i could find.
ColorDrawable colorDrawable = new ColorDrawable(Color.ParseColor("#ff0f62ae"));
this.ActionBar.SetBackgroundDrawable(colorDrawable);
I tought this would work but now i get this exception and i cannot figure out why this isnt working for me.
This is the exception:
Object reference not set to an instance of an object
Can someone explain to me what i am doeing wrong and maybe show me how i can fix this.
Edit
After an couple of comments i've tried this:
<resources>
<style name="AppTheme"
parent="android:style/Theme.Holo.Light">
<item name="android:actionBarStyle">@style/MyActionBar</item>
</style>
<style name="MyActionBar" parent="@android:style/Widget.Holo.Light.ActionBar">
<item name="android:background">@color/</item>
<item name="andriod:titleTextStyle">@style/MyActionBarTextAppearance</item>
</style>
<style name="MyActionBarTextAppearance" parent="@android:style/TextAppearance.Holo.Widget.ActionBar.Title">
<item name="android:textColor">@color/default_white</item>
</style>
</resources>
How can i add a custom color, and how do i assign this to my actionbar
I did in this way. Try this and let me know if it works please,
<style name="AppTheme" parent="android:Theme.Holo.Light">
<item name="android:actionBarStyle">@style/ActionBarTheme</item>
</style>
<style name="ActionBarTheme" parent="android:Widget.Holo.Light.ActionBar.Solid.Inverse">
<item name="android:background">@color/color_action_bar</item>
</style> "
And in colors.xml or add color variable in strings.xml, please add your desired color for the action bar
<color name="color_action_bar">#3450A3</color>
And mention the theme in the manifest file
<application
android:theme="@style/AppTheme" >
