title: Content in textview not showing (Android Studio)
body: <p>I'm using a grid layout to create 4 TextViews. Each of those will contain a number that was pressed by the user when creating a passcode. I'm just testing it out at the moment and I found that setting </p>
  
  <p><code>android:text="33" //any random value</code></p>
  
  <p>does absolutely nothing in showing the value on the preview window. </p>
  
  <p>Here is my code:</p>
  
  <pre><code>&lt;GridLayout
      android:layout_width="280dp"
      android:layout_height="200dp"
      android:paddingTop="75dp"
      android:orientation="horizontal"
      android:columnCount="4"
      android:layout_gravity="center"
      &gt;
  
      &lt;TextView
          android:id="@+id/firstNumberBox"
          android:layout_width="50dp"
          android:layout_height="50dp"
          android:layout_column="0"
          android:layout_marginLeft="10dp"
          android:layout_marginRight="10dp"
          android:background="@drawable/pin_value_border"
          android:gravity="center"
          android:paddingTop="50dp"
          android:text="33"
          android:textColor="@color/whitec"
          android:textSize="16sp"
          /&gt;
  </code></pre>
  
  <p>pin_value_border.xml:</p>
  
  <pre><code>&lt;shape xmlns:android="http://schemas.android.com/apk/res/android"
  android:shape="rectangle" &gt;
  &lt;stroke
      android:width="2dp"
      android:color="#ffffff" /&gt;
  &lt;/shape&gt;
  </code></pre>
  
  <p>Below is a picture showing my code and what I'm referring to with the problem:</p>
