TextInputLayout如果EditText聚焦与否，我需要更改密码切换的颜色。我已经这样做了，但它不起作用。颜色总是等于浅灰色（从状态聚焦 = 假）

布局

    <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">

    <android.support.design.widget.TextInputEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@null"
        android:inputType="textPassword" />
</android.support.design.widget.TextInputLayout>

color_password_toggle

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/color_green" android:state_checked="true"  />
    <item android:color="@color/color_grey" android:state_focused="true" />
    <item android:color="@color/color_light_grey" android:state_focused="false" />

password_toggle_selector

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/ic_eye" android:state_checked="true />
    <item android:drawable="@drawable/ic_eye_off" />
