如何在将错误设置为特定的textinputlayout（其中包含edittext）时不更改标签的颜色？

Question

我在其中使用Textinputlayout和edittext，问题是在验证时将错误设置为textinputlayout时，它会将提示标签的颜色也更改为红色。当出现错误时，我想用另一种颜色代替红色，只有下划线颜色和错误文本应该变成红色。

上面显示的图片是问题，我不希望电子邮件标签为红色。

下面是我的代码。

xml文件

     <android.support.design.widget.TextInputLayout
            android:layout_marginTop="30dp"
            android:layout_marginLeft="20dp"
            android:layout_marginRight="20dp"
            android:layout_marginBottom="15dp"
 app:errorTextAppearance="@style/error_appearance"
        app:hintTextAppearance="@style/TextLabel1"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/et1"
            android:padding="0dp">

        <EditText

您需要使用自定义样式覆盖文本输入布局的默认样式。

styles.xml

<resources>

 <style name="TextLabel">
    <item name="android:textColorHint">@color/colorPrimary</item> <!-- Your Hint Color -->
    <item name="android:textSize">18sp</item>
    <item name="colorAccent">@color/colorPrimary</item>
    <item name="colorControlNormal">@color/colorPrimary</item>
    <item name="colorControlActivated">@color/colorPrimary</item>
</style>

<style name="error_appearance" parent="@android:style/TextAppearance">
    <item name="android:textColor">@color/colorAccent</item>
</style>

</resources>

activity_layout.xml

        <android.support.design.widget.TextInputLayout
            android:id="@+id/input_layout_mobile"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="5dp"
            android:theme="@style/TextLabel"
            app:errorTextAppearance="@style/error_appearance">

            <EditText
                android:id="@+id/edt_mobile"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:drawableLeft="@drawable/ic_phone_iphone_black_24dp"
                android:drawablePadding="8dp"
                android:drawableTint="@color/colorPrimary"
                android:hint="@string/email"
                android:inputType="number"
                android:textColor="#000" />
        </android.support.design.widget.TextInputLayout>

您需要为其定义自己的样式，如下所示。在style.xml中。您可以定义任何样式。更改文本的颜色，大小和其他属性。

<style name="text_error_profile" parent="@android:style/TextAppearance">
    <item name="android:textColor">colorYouWant</item>
     <item name="android:textColorHint">colorHintyouwant</item>
</style>

在内部添加app:errorTextAppearance="@style/error_appearance"，如下所示进行应用。

<android.support.design.widget.TextInputLayout
  .....
  ....
  app:errorTextAppearance="@style/text_error_profile"

您可以使用以下命令以编程方式更改提示颜色。验证失败后添加此内容。

 editText.setHintTextColor(hintcoloryouwant);
