Where is this top border in Theme.Light.NoTitleBar coming from?
<p>I have the following application.xml</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.currency.mobile.android"&gt;
    &lt;uses-permission android:name="android.permission.INTERNET"/&gt;
    &lt;application android:icon="@drawable/icon" android:label="@string/app_name"
                 android:theme="@android:style/Theme.Light.NoTitleBar"&gt;

        &lt;activity android:name=".MainActivity" android:noHistory="true"&gt;
            &lt;intent-filter&gt;
                &lt;action android:name="android.intent.action.MAIN"/&gt;
                &lt;category android:name="android.intent.category.LAUNCHER"/&gt;
            &lt;/intent-filter&gt;
        &lt;/activity&gt;

        &lt;activity android:name=".LoginActivity"/&gt;
        &lt;activity android:name=".HomeActivity" /&gt;
        &lt;activity android:name=".FriendsActivity"/&gt;
        &lt;activity android:name=".PlacesActivity"/&gt;
        &lt;activity android:name=".ProfileActivity"/&gt;
        &lt;activity android:name=".PurchasesActivity"/&gt;
    &lt;/application&gt;
&lt;/manifest&gt;
</code></pre>

<p>This is my tab view:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;TabHost xmlns:android="http://schemas.android.com/apk/res/android"
         android:id="@android:id/tabhost"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"&gt;
    &lt;LinearLayout
            android:orientation="vertical"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:padding="5dp"&gt;
        &lt;TabWidget
                android:id="@android:id/tabs"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"/&gt;
        &lt;FrameLayout
                android:id="@android:id/tabcontent"
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:padding="5dp"/&gt;
    &lt;/LinearLayout&gt;
&lt;/TabHost&gt;
</code></pre>

<p>When using Theme.Light.NoTitleBar I get this ugly line in the middle:</p>

<p><img src="http://i.stack.imgur.com/nVA0j.png" alt="alt text"></p>

<p>But when I use Theme.Black it doesn't have such a weird line. Any way to fix it so that I can use light theme? </p>
