Question

我正在使用自定义样式在TextInputLayout内部使用Edittext，以便我可以更改提示颜色。如果我在不设置样式的情况下使用EditText，setError方法可以正常工作，但是我的样式设置会抛出下一个异常：

java.lang.UnsupportedOperationException: Failed to resolve attribute at index 24: TypedValue{t=0x3/d=0x2b5 "res/color/secondary_text_material_dark.xml" a=1 r=0x1060166}

这是EditText的XML

<android.support.design.widget.TextInputLayout
        android:id="@+id/email_input_layout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginRight="34dp"
        android:layout_marginLeft="34dp"
        android:layout_marginTop="12dp"
        android:theme="@style/TextLabel">

        <EditText
            android:id="@+id/email_edittext"
            android:inputType="textEmailAddress"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:singleLine="true"
            android:textColor="@color/colorText"
            android:textColorHint="@color/colorMediumText"
            android:hint="@string/email_hint"
            android:nextFocusUp="@id/email_edittext"
            android:nextFocusLeft="@id/email_edittext"/>

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

这是styles.xml中定义的样式。

<style name="TextLabel" parent="TextAppearance.AppCompat">
    <item name="android:textColorHint">@color/colorLightText</item>
    <item name="android:textSize">14dp</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="colorControlNormal">@color/colorMediumText</item>
    <item name="colorControlActivated">@color/colorAccent</item>
</style>

这是产生错误的行：

emailInputLayout.setError("Incorrect email");

知道发生了什么事吗？

提前致谢，

我发现错误，这些属性必须是样式：

<item name="android:textColorHighlight">@color/COLOR</item>
<item name="android:textColorLink">@color/COLOR</item>

SetError在TextInputLayout中生成具有自定义样式的异常
