参考谷歌发布的新TextInputLayout，如何更改浮动标签文本颜色?
在样式中设置colorControlNormal, colorControlActivated, colorControlHighLight没有帮助。
这是我现在拥有的:

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>

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>
其他回答
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>

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>

<item name="textInputStyle">@style/Widget.App.TextInputLayout</item>
<style name="AppTheme2" parent="AppTheme">
<!-- Customize your theme here. -->
<item name="colorControlNormal">#fff</item>
<item name="colorControlActivated">#fff</item></style>
将此添加到styles并将TextInputLayout Theam设置为App2，它将工作;)
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。
在我的情况下，我添加了这个“app:hintTextAppearance=“@color/colorPrimaryDark”在我的TextInputLayout小部件。
