title: How a TextView never go out of the screen if the user scroll Down?
body: <p>I'm a android intermediate developer and I need someone expirence to do a trick in my content activity;</p>
  
  <p>this is my content Activity:</p>
  
  <pre><code>&lt;ScrollView
      android:layout_width="match_parent"
      android:layout_height="match_parent" &gt;
    ....
   // How this TextView never go out of the screen if the user scroll Down
    &lt;TextView ... /&gt;  
    ....
  &lt;/ScrollView&gt;
  </code></pre>
  
  <p>*What I did :</p>
  
  <pre><code>   &lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
      android:layout_width="fill_parent"
     android:layout_height="fill_parent"
      android:orientation="vertical" &gt;
  
    &lt;TextView ... android:visibility="gone" /&gt;
  
      &lt;ScrollView
       android:layout_width="match_parent"
      android:layout_height="match_parent" &gt;
      ....
    // 
   &lt;TextView ...android:visibility="visible"/&gt;
    ....
    &lt;/ScrollView&gt;
   &lt;/FrameLayout&gt;
  </code></pre>
  
  <p>I thought about having 2 TextView, one Invisible in the top and the other visible. 
  When the user scroll down and before the second TextView will be gone I set the first textView visible.</p>
  
  <p>is it a good way ? if so how to do it ? </p>
