title: EditText line is not visible and does not change colour
body: <p>So for a while now, I've been tried to fix the issue I've been having with the EditText field, as it does not show the single line under where the Hint or actual text would go. Typically, the line would be black by default, so my question is this; how do I enable the line to show up again, as well as how do I change the colour of it? (I would assume android:backgroundHint would do the trick however I just cannot see the line at all so cannot test it). I am using API 24/25.</p>
  
  <p>Below is a sample of my XML code as well as the emulator output:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:tools="http://schemas.android.com/tools"
  android:id="@+id/activity_register"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  tools:context="com.example.michael.whatsupldn.RegisterActivity"&gt;
  
  
  &lt;LinearLayout
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:orientation="vertical"
      android:layout_alignParentTop="true"
      android:layout_alignParentStart="true"&gt;
  
    &lt;EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="Name"
        android:layout_margin="16dp"/&gt;
  
  &lt;/LinearLayout&gt;
  
  &lt;/RelativeLayout&gt;
