title: Android: TextView takes up space with no text
body: <p>I have a TextView that is still taking up space when there is no text to display. This happens only on OS 1.6. When my app runs on 2.2, the height of the TextView collapses so that it doesn't take up any space. Is there some property I can set in TextView to cause it to collapse or disappear when no text is set? Here is my xml code.</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:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:gravity="center"
    android:layout_marginTop="3dp"
    android:layout_marginRight="3dp" 
    android:background="#ff737373"
    android:padding="3dp"
    android:minWidth="64dp" &gt;
    &lt;ImageView
      android:layout_height="wrap_content"
      android:layout_width="wrap_content"
      android:tag="tabImage"&gt;&lt;/ImageView&gt;
    &lt;TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:textSize="16sp"
      android:tag="tabCaption"
      android:textColor="#ffd9d9d9" /&gt;
  &lt;/LinearLayout&gt;
  </code></pre>
