<style name="MyAppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorControlActivated">#e91e63</item>
    <item name="android:colorForeground">#33691e</item>
    <item name="colorControlNormal">#f57f17</item>
    <item name="android:textColorSecondary">#673ab7</item>
</style>

在最新版本的支持库(23.0.0+)中，TextInputLayout采用以下XML属性来编辑浮动标签颜色:

<style name="TextAppearance.App.TextInputLayout" parent="@android:style/TextAppearance">
    <item name="android:textColor">@color/red</item>
    <item name="android:textSize">14sp</item>
</style>

<android.support.design.widget.TextInputLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textColorHint="@color/gray"  //support 23.0.0
    app:hintTextAppearance="@style/TextAppearence.App.TextInputLayout" >

    <android.support.v7.widget.AppCompatEditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/hint" />
</android.support.design.widget.TextInputLayout>

试试下面的代码，它在正常状态下工作

 <android.support.design.widget.TextInputLayout
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:theme="@style/TextLabel">

     <android.support.v7.widget.AppCompatEditText
         android:layout_width="match_parent"
         android:layout_height="wrap_content"
         android:hint="Hiiiii"
         android:id="@+id/edit_id"/>

 </android.support.design.widget.TextInputLayout>

在样式文件夹TextLabel代码

 <style name="TextLabel" parent="TextAppearance.AppCompat">
    <!-- Hint color and label color in FALSE state -->
    <item name="android:textColorHint">@color/Color Name</item> 
    <item name="android:textSize">20sp</item>
    <!-- Label color in TRUE state and bar color FALSE and TRUE State -->
    <item name="colorAccent">@color/Color Name</item>
    <item name="colorControlNormal">@color/Color Name</item>
    <item name="colorControlActivated">@color/Color Name</item>
 </style>

设置为应用程序的主题，它只突出显示状态

 <item name="colorAccent">@color/Color Name</item>

更新:

UnsupportedOperationException:不能转换为颜色:类型=0x2在api 16或以下

你在使用材料组件库吗

你可以在你的主题中添加以下几行

 <item name="colorPrimary">@color/your_color</item> // Activated State
 <item name="colorOnSurface">@color/your_color</item> // Normal State

或者你想要不同的颜色在正常状态和激活状态和自定义遵循下面的代码

<style name="Widget.App.TextInputLayout" parent="Widget.MaterialComponents.TextInputLayout.OutlinedBox">
    <item name="materialThemeOverlay">@style/ThemeOverlay.App.TextInputLayout</item>
    <item name="shapeAppearance">@style/ShapeAppearance.App.SmallComponent</item> //Changes the Shape Apperance
    <!--<item name="hintTextColor">?attr/colorOnSurface</item>-->   //When you added this line it will applies only one color in normal and activate state i.e colorOnSurface color
</style>

<style name="ThemeOverlay.App.TextInputLayout" parent="">
    <item name="colorPrimary">@color/colorPrimaryDark</item>  //Activated color
    <item name="colorOnSurface">@color/colorPrimary</item>    //Normal color
    <item name="colorError">@color/colorPrimary</item>        //Error color

    //Text Appearance styles
    <item name="textAppearanceSubtitle1">@style/TextAppearance.App.Subtitle1</item>
    <item name="textAppearanceCaption">@style/TextAppearance.App.Caption</item>

    <!--Note: When setting a materialThemeOverlay on a custom TextInputLayout style, don’t forget to set editTextStyle to either a @style/Widget.MaterialComponents.TextInputEditText.* style or to a custom one that inherits from that.
    The TextInputLayout styles set materialThemeOverlay that overrides editTextStyle with the specific TextInputEditText style needed. Therefore, you don’t need to specify a style tag on the edit text.-->
    <item name="editTextStyle">@style/Widget.MaterialComponents.TextInputEditText.OutlinedBox</item>
</style>

<style name="TextAppearance.App.Subtitle1" parent="TextAppearance.MaterialComponents.Subtitle1">
    <item name="fontFamily">@font/your_font</item>
    <item name="android:fontFamily">@font/your_font</item>
</style>

<style name="TextAppearance.App.Caption" parent="TextAppearance.MaterialComponents.Caption">
    <item name="fontFamily">@font/your_font</item>
    <item name="android:fontFamily">@font/your_font</item>
</style>

<style name="ShapeAppearance.App.SmallComponent" parent="ShapeAppearance.MaterialComponents.SmallComponent">
    <item name="cornerFamily">cut</item>
    <item name="cornerSize">4dp</item>
</style>

添加下面的行到您的主题，否则您可以设置样式textinputlayout在您的xml

<item name="textInputStyle">@style/Widget.App.TextInputLayout</item>
