How to set TextInputLayout error message colour?

Question

How can I change the colour of the error message that can be set to appear below the text field in a TextInputLayout (via setError(...) – see error state here)?

It normally shows as a red colour, which I want to change. Which item names/keys should I use in my styles.xml file to target the colour?

Thanks in advance.

Edit:

Added app:errorTextAppearance key to my TextInputLayout:

<android.support.design.widget.TextInputLayout         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_marginTop="8dp"         android:id="@+id/welcome_current_week_container"         app:errorTextAppearance="@style/WelcomeErrorAppearance">         <EditText             ..../>     </android.support.design.widget.TextInputLayout> </LinearLayout> 

and the error appearance (set to green for testing):

<style name="WelcomeErrorAppearance" parent="@android:style/TextAppearance">     <item name="android:textColor">@android:color/holo_green_dark</item> </style> 

The result is that the hint as well as the error message is coloured (screenshots from scaled Android Emulator):

Regular (no error):

Error state:

Edit 2/Outcome:

When the error message appears, the hint above the field changes to the same colour as the error message, overriding hint colour – this is by design.

Answer 1

Create a custom style which uses @android:style/TextAppearance as parent in your styles.xml file:

<style name="error_appearance" parent="@android:style/TextAppearance">     <item name="android:textColor">@color/red_500</item>     <item name="android:textSize">12sp</item> </style> 

And use it in your TextInputLayout widget:

 <android.support.design.widget.TextInputLayout             android:id="@+id/emailInputLayout"             android:layout_width="match_parent"             android:layout_height="wrap_content"             app:errorTextAppearance="@style/error_appearance"> 

Edit: Set the hint on the object, which is inside your TextInputLayout (EditText, TextView, etc.) to hold different colors for the hint and the error.

Actually, to change just the error message color, you can set textColorError in your theme (and also set colorControlNormal and colorControlActivated for the general widget and hint text color). TextInputLayout picks up that attribute. NOTE: if you set errorTextAppearance to a custom style then textColorError will have no effect.

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">     <item name="colorControlNormal">@color/control_normal</item>     <item name="colorControlActivated">@color/control_activated</item>     <item name="textColorError">@color/error</item>     <!-- other styles... --> </style> 

And in your AndroidManifest.xml:

<application     android:theme="@style/AppTheme"     android:icon="@drawable/ic_launcher"     android:label="@string/app_name">      <!-- ... -->  </application>
