你可以在程序上使用:
/* Here you get int representation of an HTML color resources */
int yourColorWhenEnabled = ContextCompat.getColor(getContext(), R.color.your_color_enabled);
int yourColorWhenDisabled = ContextCompat.getColor(getContext(), R.color.your_color_disabled);
/* Here you get matrix of states, I suppose it is a matrix because using a matrix you can set the same color (you have an array of colors) for different states in the same array */
int[][] states = new int[][]{new int[]{android.R.attr.state_enabled}, new int[]{-android.R.attr.state_enabled}};
/* You pass a ColorStateList instance to "setDefaultHintTextColor" method, remember that you have a matrix for the states of the view and an array for the colors. So the color in position "colors[0x0]" will be used for every states inside the array in the same position inside the matrix "states", so in the array "states[0x0]". So you have "colors[pos] -> states[pos]", or "colors[pos] -> color used for every states inside the array of view states -> states[pos] */
myTextInputLayout.setDefaultHintTextColor(new ColorStateList(states, new int[]{yourColorWhenEnabled, yourColorWhenDisabled})
解释:
Get int color value from a color resource (a way to present rgb colors used by android). I wrote ColorEnabled, but really it should be, for this answer, ColorHintExpanded & ColorViewCollapsed. Anyway this is the color you will see when the hint of a view "TextInputLayout" is on Expanded or Collapsed state; you will set it by using next array on function "setDefaultHintTextColor" of the view. Reference: Reference for TextInputLayout - search in this page the method "setDefaultHintTextColor" for more info
查看上面的文档,你可以看到函数通过使用ColorStateList来设置展开和折叠提示的颜色。
ColorStateList docs
To create the ColorStateList I first created a matrix with the states I want, in my case state_enabled & state_disabled (whose are, in TextInputLayout, equals to Hint Expanded and Hint Collapsed [I don't remember in which order lol, anyway I found it just doing a test]). Then I pass to the constructor of the ColorStateList the arrays with int values of color resources, these colors have a correspondences with the states matrix (every element in colors array correspond to the respective array in states matrix at same position). So the first element of the colors array will be used as color for every state in the first array of the states matrix (in our case the array has only 1 element: enabled state = hint expanded state for TextInputLayut). Last things states have positive / negative values, and you have only the positive values, so the state "disabled" in android attrs is "-android.state.enabled", the state "not focused" is "-android.state.focused" ecc.. ecc..
希望这对你有帮助。 再见,祝你编码愉快。

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>
现在,简单地使用colorAccent和colorPrimary就可以完美地工作了。
它为我工作..... 在TextInputLayout中添加提示颜色
<android.support.design.widget.TextInputLayout
android:textColorHint="#ffffff"
android:id="@+id/input_layout_password"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<EditText
android:id="@+id/edtTextPassword"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="15dp"
android:hint="Password"
android:inputType="textPassword"
android:singleLine="true"
/>
</android.support.design.widget.TextInputLayout>
当您聚焦文本标签时,更改文本标签的颜色。也就是在里面打字。你必须加上specify
<item name="android:textColorPrimary">@color/yourcolorhere</item>
请注意: 您必须将所有这些实现添加到您的主题中。
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>
