Customizing title bar in Android. Getting Exception You need to use a Theme.AppCompat theme

问题

Search a lot but nothing found useful.

I am creating a simple app with my customized Title bar but not getting so far from days. I am using this https://developer.android.com/training/basics/actionbar/styling.html.

Manifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.title"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="11"
        android:targetSdkVersion="17" />

    <application
        android:theme="@style/CustomActionBarTheme"//title bar
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" >
        <activity
            android:name="com.example.title.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

</manifest>

I have created theme.xml like res/values/themes.xml.

Code:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!-- the theme applied to the application or activity -->
    <style name="CustomActionBarTheme"
           parent="@style/Theme.AppCompat.Light.DarkActionBar">
        <item name="android:actionBarStyle">@style/MyActionBar</item>

        <!-- Support library compatibility -->
        <item name="actionBarStyle">@style/MyActionBar</item>
    </style>

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

        <!-- Support library compatibility -->
    </style>
</resources>

Getting Exception :( logcat:

Guide me with this please

回答1:

Your MainActivity probably extends from ActionBarActivity. And you are probably referencing AppCompat. So you need to use Theme.AppCompat.

Also you have android:minSdkVersion="11". So there is no need to extend ActionBarActivty and no need to reference AppCompat and no need for Theme.AppCompat
