Question

我有一个非常简单的文本视图：

<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/app_name"
android:textSize="20sp"
android:textColor="@style/basic_text_color"
android:layout_gravity="center"
android:id="@+id/toolbar_title" />

@ style / basic_text_color是我想在应用中重复使用很多时间的颜色，所以我在app_colors.xml文件夹下创建了一个values：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!--  Text colors style-->
    <style name="basic_text_color" parent="@android:style/TextAppearance">
         <item name="android:textColor">#ff932e</item>
    </style>

    <!-- some other color styles-->
</resources>

应用程序编译成功，但随后执行时它将挂起并在LogCat中提示跟随错误：

所以看起来这里的错误是＆＃34;资源不是ColorStateList（颜色或路径）：TypedValue {t = 0x1 / d = 0x7f0b0124 a = -1 r = 0x7f0b0124}＆＃34; ...

我是否以错误的方式设置了字体颜色？或者其他任何问题都出错了？谢谢！

Answer 1

colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="basic_text_color">#ff932e</color> 
</resources>

布局

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/app_name"
    android:textSize="20sp"
    android:textColor="@colors/basic_text_color"
    android:layout_gravity="center"
    android:id="@+id/toolbar_title" />

如果要更改textColor，则必须创建一个颜色资源文件，因为在您的问题中，您尝试将颜色设置为样式。

Answer 2

您可能打算使用：

style="@style/basic_text_color"

Answer 3

您应该使用color属性而不是样式1。

<color name="basic_text_color">#YOUR COLOR GOES HERE</color>

Answer 4

如果要从Java设置颜色，可以使用以下内容：

myView.setBackgroundTintList(ColorStateList.valueOf(getResources().getColor(R.color.grey_300)));

Android文本样式错误 - 资源不是ColorStateList
