Android Studio: Remove default header

Question

I am just beginning to learn Android Studio (version 2.0, running on Windows 7). When I create a new project (Empty Activity template) Android Studio places a header at the top of the project. How can I remove the header?

Here's a picture of the problem. I want to get rid of the 'My Greeting Card' header.

Answer 1

You have to simply navigate like below....

app -> res -> values -> styles.xml

Find <style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar"> line.

Theme.AppCompat.Light.DarkActionBar line shows, how your activity will look like.

There are lots of Themes available. Just remove DarkActionBar it and press Cntrl+Space to explore another themes. In your case, you do not want Header which is called ActionBar in Android Terminology.

So, Just change theme to Theme.AppCompat.Light.NoActionBar and you are done.

Well the answer is already given, but still i would like to add if you don't want any kind of actionbar on top of the activity simply do this. go to your res->values->styles.xml and add these xml code

<resources>
    <!-- Base application theme. -->
    <style name="AppTheme.Base" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">#3F51B5</item>
        <!-- Light Indigo -->
        <item name="colorPrimaryDark">#3949AB</item>
        <!-- Dark Indigo -->
        <item name="colorAccent">#00B0FF</item>
        <!-- Blue -->
    </style>
    <style name="AppTheme" parent="AppTheme.Base"></style>
</resources>

and reference the theme in the style on any activity you want, like below in the manifest using android:theme=@style/AppTheme.

<application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">
        <activity
            android:name=".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>
        <activity
            android:name=".DetailActivity"
            android:parentActivityName=".MainActivity">
            <meta-data
                android:name="android.support.PARENT_ACTIVITY"
                android:value=".MainActivity" />
        </activity>
    </application>
