title: How to change color of the password toggle in TextInputLayout?
body: <p>I need to change color of the password toggle in <code>TextInputLayout</code> if <code>EditText</code> is focused or not. I've done it this way but it's not working. The color is always equals color light grey (from state focused = false) </p>
  
  <p>layout</p>
  
  <pre><code>    &lt;android.support.design.widget.TextInputLayout
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          app:passwordToggleEnabled="true"
          app:passwordToggleDrawable="@drawable/password_toggle_selector"
          app:passwordToggleTint="@color/color_password_toggle"&gt;
  
      &lt;android.support.design.widget.TextInputEditText
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:background="@null"
          android:inputType="textPassword" /&gt;
  &lt;/android.support.design.widget.TextInputLayout&gt;
  </code></pre>
  
  <p>color_password_toggle</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:color="@color/color_green" android:state_checked="true"  /&gt;
      &lt;item android:color="@color/color_grey" android:state_focused="true" /&gt;
      &lt;item android:color="@color/color_light_grey" android:state_focused="false" /&gt;
  </code></pre>
  
  <p></p>
  
  <p>password_toggle_selector</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:drawable="@drawable/ic_eye" android:state_checked="true /&gt;
