title: LinearLayout doesn't display all components
body: <p>I'm using a <code>LinearLayout</code> with <code>orientation="horizontal"</code> but there are two components that I can't see when the app run... This is the code:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="match_parent" android:layout_height="match_parent"&gt;
  
      &lt;LinearLayout
          android:orientation="horizontal"
          android:layout_width="fill_parent"
          android:layout_height="wrap_content"&gt;
  
          &lt;ImageView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:id="@+id/a" /&gt;
  
          &lt;TextView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:textAppearance="?android:attr/textAppearanceSmall"
              android:id="@+id/d" /&gt;
  
          &lt;TextView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:textAppearance="?android:attr/textAppearanceSmall"
              android:id="@+id/b" /&gt;
  
          &lt;ImageView
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:id="@+id/c" /&gt;
      &lt;/LinearLayout&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>I don't know where the problem can be. Anyone can help me?</p>
