is it possible to set transparent for viewpager of android
<p>I want to make transparent for <code>ViewPager</code>, but I can't find any way to get it (It always has WHITE color, not transparent)</p>

<p>My layout: main_activity.xml</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/wallpaper"&gt;

    &lt;android.support.v4.view.ViewPager
        android:id="@+id/view_pager"
        android:background="#00ffffff"
        android:layout_width="match_parent"
        android:layout_height="match_parent" &gt;
    &lt;/android.support.v4.view.ViewPager&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>The layout for first fragment:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:background="#00ffffff"
    android:layout_width="match_parent"
    android:layout_height="match_parent"&gt;

    &lt;TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="AAAAAAAAAAAAAAAA"
        android:id="@+id/textView"
        android:layout_gravity="center_horizontal"/&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>And the layout for second fragment:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:background="#00ffffff"
    android:layout_width="match_parent"
    android:layout_height="match_parent"&gt;

    &lt;Button
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="New Button"
        android:id="@+id/button"
        android:layout_gravity="center_horizontal"/&gt;
&lt;/LinearLayout&gt;
</code></pre>

<p>I already set transparent for both background of <code>ViewPager</code> and layouts for fragments. But it's always WHITE.</p>

<p>So, Is it possible to set transparent for <code>ViewPager</code>? Can you explain it for me (if any). Any suggestion will be appreciate. Thank you.</p>

<p>EDIT:
I used the default theme for activity:</p>
