title: Activity with transparent background
body: <p>what I want to achieve is activity with dialog-like transparency with 100% visibility of RelativeLayout content. This is activity's xml:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical" &gt;
  
      &lt;RelativeLayout
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          android:layout_marginBottom="50dip"
          android:layout_marginLeft="8dip"
          android:layout_marginRight="8dip"
          android:layout_marginTop="50dip"&gt;
          (...)
      &lt;/RelativeLayout&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
  
  <p>and this is manifest:</p>
  
  <pre><code>&lt;activity
          android:name="com.acentic.rcontrol.activities.MyActivity"
          android:theme="@android:style/Theme.Translucent.NoTitleBar" &gt;
  &lt;/activity&gt;
  </code></pre>
  
  <p>Right now background is still visible, what am I doing wrong?</p>
  
  <p>--- EDIT:
  I added</p>
  
  <pre><code>android:background="#c0000000"
  </code></pre>
  
  <p>to LinearLayout. Now background is transparent as I wanted to, but also TextViews inside RelativeLayout are also transparent.. how to change it?</p>
