title: TextViews are on top of each other - Android XML
body: <p>I just started to learn Android Development (with Android Studio), but I have some trouble.
  The TextViews on the activity_main.xml are placed on top of each other, instead of under each other.</p>
  
  <p>I just copied the default TextView and change the text to another string.</p>
  
  <pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:paddingLeft="@dimen/activity_horizontal_margin"
  android:paddingRight="@dimen/activity_horizontal_margin"
  android:paddingTop="@dimen/activity_vertical_margin"
  android:paddingBottom="@dimen/activity_vertical_margin"
  tools:context=".Main"&gt;
  
  &lt;TextView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="@string/hello_world" /&gt;
  &lt;TextView
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:text="@string/matttest" /&gt;
  
  &lt;/RelativeLayout&gt;
  </code></pre>

  <p>How can I make sure that the TextViews are placed under each other, instead of on top of each other?</p>
  
  <p>Thanks
