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>

而不是Brahmam Yamani的答案，我更喜欢使用Widget.Design.TextInputLayout作为父。这确保了所有必需的项都存在，即使不是所有项都被覆盖。在Yamanis的答案中，如果调用setErrorEnabled(true)，应用程序将崩溃与一个无法解析的资源。

简单地更改样式如下:

<style name="TextLabel" parent="Widget.Design.TextInputLayout">
    <!-- 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>

这很简单，但由于多个视图在不同的配置/名称空间中具有相同的属性，开发人员会感到困惑。

在TextInputLayout的情况下，我们每次都有一个不同的视图和参数，要么与TextInputEditText或直接到TextInputLayout。

我使用了以上所有的修复: 但我发现我在吸毒

                app:textColorHint="@color/textcolor_black"

其实我应该用

                android:textColorHint="@color/textcolor_black"

作为TextinputLayout的属性

textcolor_black.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:color="@color/black_txt" android:state_enabled="true" />
    <item android:color="@color/black_txt" android:state_selected="true" />
    <item android:color="@color/txtColorGray" android:state_selected="false" />
    <item android:color="@color/txtColorGray" android:state_enabled="false" />
</selector>

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>

好的，所以，我发现这个答案非常有用，感谢所有贡献的人。只是补充一点。公认的答案确实是正确的答案…但是…在我的情况下，我正在寻找实现下面的错误消息EditText小部件与app: errorrenabled ="true"和这一行使我的生活困难。似乎这覆盖了我为android.support.design.widget. textinputlayout选择的主题，它有一个由android:textColorPrimary定义的不同的文本颜色。

最后，我将文本颜色直接应用到EditText小部件上。我的代码是这样的:

styles.xml

<item name="colorPrimary">@color/my_yellow</item>
<item name="colorPrimaryDark">@color/my_yellow_dark</item>
<item name="colorAccent">@color/my_yellow_dark</item>
<item name="android:textColorPrimary">@android:color/white</item>
<item name="android:textColorSecondary">@color/dark_gray</item>
<item name="android:windowBackground">@color/light_gray</item>
<item name="windowNoTitle">true</item>
<item name="windowActionBar">false</item>
<item name="android:textColorHint">@color/dark_gray</item>
<item name="android:colorControlNormal">@android:color/black</item>
<item name="android:colorControlActivated">@android:color/white</item>

我的小部件:

<android.support.design.widget.TextInputLayout
        android:id="@+id/log_in_layout_name"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:errorEnabled="true">

        <EditText
            android:id="@+id/log_in_name"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:textColor="@android:color/black"
            android:ems="10"
            android:hint="@string/log_in_name"
            android:inputType="textPersonName" />
</android.support.design.widget.TextInputLayout>

现在它显示黑色文本颜色而不是textColorPrimary白色。

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

解决方案

更新:

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>
