title: how to make hint disappear when edittext is touched?
body: <p>In my application in android are many EditText fields. And I ran into a problem with hint.
  It is not disappearing when EditText is focused, but it disappears when I start to write something.
  How can this problem be fixed? Because I need the hint to disappear when the EditText field is touched.</p>
  
  <p>It is for example:</p>
  
  <pre><code>&lt;EditText
      android:layout_width="260dp"
      android:layout_height="30dp"
      android:ems="10"
      android:inputType="text"
      android:id="@+id/driv_lic_num_reg"
      android:hint="@string/driver_license_numb"
      android:textColor="@color/black"
      android:textColorHint="@color/grey_hint"
      android:background="@drawable/input_field_background"
      android:layout_alignParentTop="true"
      android:layout_centerHorizontal="true"
      android:layout_margin="2dp"
      android:textCursorDrawable="@color/black"
      android:textSize="15dp"
      android:paddingLeft="10dp"
      android:nextFocusDown="@+id/pass_reg"
      android:imeOptions="actionNext"
      android:maxLines="1"
      android:maxLength="50"
      android:focusableInTouchMode="true"/&gt;
  </code></pre>
