Java – Changing EditText bottom line color with appcompat v7

androidandroid-edittextandroid-layoutandroid-stylesjava

I am using appcompat v7 to get the look consistent on Android 5 and less. It works rather well. However I cannot figure out how to change the bottom line color and the accent color for EditTexts. Is it possible?

I have tried to define a custom android:editTextStyle (cf. below) but I only succeeded to change the full background color or text color but not the bottom line nor the accent color. Is there a specific property value to use? do I have to use a custom drawable image through the android:background property? is it not possible to specify a color in hexa?

 <style name="Theme.App.Base" parent="Theme.AppCompat.Light.DarkActionBar">
     <item name="android:editTextStyle">@style/Widget.App.EditText</item>
 </style>

 <style name="Widget.App.EditText" parent="Widget.AppCompat.EditText">
     ???
 </style>

According to android API 21 sources, EditTexts with material design seem to use colorControlActivated and colorControlNormal. Therefore, I have tried to override these properties in the previous style definition but it has no effect. Probably appcompat does not use it. Unfortunately, I cannot find the sources for the last version of appcompat with material design.

Finally, I have found a solution. It simply consists of overriding the value for colorControlActivated, colorControlHighlight and colorControlNormal in your app theme definition and not your edittext style. Then, think to use this theme for whatever activity you desire. Below is an example:

<style name="Theme.App.Base" parent="Theme.AppCompat.Light.DarkActionBar">
    <item name="colorControlNormal">#c5c5c5</item>
    <item name="colorControlActivated">@color/accent</item>
    <item name="colorControlHighlight">@color/accent</item>
</style>
