title: How to use layout_below in RelativeLayout?
body: <p>Here is my code(not all code,i have deleted some):</p>
  
  <pre><code>&lt;RelativeLayout
          android:id="@+id/info_in_my"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:layout_below="@id/head_in_my"
          android:layout_marginTop="@dimen/spacing_size_36dp"&gt;
  
          &lt;ImageView
              android:id="@+id/pic_in_my"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:layout_marginStart="@dimen/spacing_size_36dp"
              android:layout_alignParentStart="true"
              android:src="@mipmap/icon_policeman" /&gt;
          &lt;TextView
              android:id="@+id/name_in_my"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="AAAAAA"
              android:layout_toEndOf="@id/pic_in_my"
              android:layout_centerInParent="true"
              android:textColor="@color/font_white"
              android:textSize="@dimen/font_size_18sp" /&gt;
  
          &lt;TextView
              android:id="@+id/organization_in_my"
              android:layout_width="wrap_content"
              android:layout_height="wrap_content"
              android:text="BBBBBBBBBBBBBBBBB"
              android:layout_below="@+id/name_in_my"
              android:layout_toEndOf="@+id/pic_in_my"
              android:textSize="@dimen/font_size_12sp"
              android:textColor="@color/font_white" /&gt;
  
      &lt;/RelativeLayout&gt;
  </code></pre>

  <p>I want String <code>BBBBBBBBB</code> is below String <code>AAAAAA</code>, so it's not right.</p>
  
  <p>And i deleted <code>android:layout_centerInParent="true"</code> in the first <code>TextView</code> but no changes.</p>
  
  <p>Is  <code>android:layout_below="@+id/name_in_my"</code> useless when First <code>View</code> uses <code>android:layout_centerInParent="true"</code> </p>
  
  <p>I want to know why?</p>
