title: Prompt for EditText
body: <p>I'm trying to get a prompt for my EditText to show such as "Please Enter Answer Here" and when the user taps on the EditText to type thier Answer the text should disappear and be blank for them to enter their answer in. </p>
  
  <p>As of right now this is what I have for my .xml </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"
  tools:context=".AnswerActivity" &gt;
  
  &lt;EditText
      android:id="@+id/edittxt_answer"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:ems="10"
      android:inputType="textMultiLine" /&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>
  
  <p>In my .java </p>
  
  <pre><code>public class AnswerActivity extends Activity{
  
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_answer);
  
      EditText ans = (EditText) findViewById(R.id.edittxt_answer);
      //Continue with acitivty.... 
  }
  </code></pre>
