如何更改Android操作栏的颜色？

Question

I am trying to change the color of my Android ActionBar, but my app is closing with an error each time. I have tried all other suggestions and fixes in other posts, but they dont seem to work for me. Also - minSdkVersion 19

Error:

My Styles.xml

<resources>
    <style name="QueryTheme" parent="@style/Theme.AppCompat">
        <!-- Any customizations for your app running on devices with Theme.Holo here -->
    </style>
    <!-- the theme applied to the application or activity -->
    <style name="CustomActionBarTheme"
        parent="@android:style/Theme.Holo.Light.DarkActionBar">
        <item name="android:actionBarStyle">@style/MyActionBar</item>
    </style>

    <!-- ActionBar styles -->
    <style name="MyActionBar"
        parent="@android:style/Widget.Holo.Light.ActionBar.Solid.Inverse">
        <item name="android:background">#2980b9</item>
    </style>
</resources>

My AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>

    package="ca.holdfastonline.menu_test_02" >

        android:theme="@style/QueryTheme" >
        <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/CustomActionBarTheme">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Thank you.

Answer 1

java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.

You have only one activity. It is using @style/CustomActionBarTheme . Your definition of CustomActionBarTheme has it inheriting from Theme.Holo.Light.DarkActionBar . That is not an AppCompat theme. Change Theme.Holo.Light.DarkActionBar to Theme.AppCompat.Light.DarkActionBar .

Answer 2

This is probably because in your Java file you are using ActionBarActivity and you should be using Activity.

More Info Basically you are using ActionBarActivity, this activity requires a Theme.AppCompact which is where your error is coming from. To fix this you would need to change to use the regular Activity or just use Theme.AppCompact
