How to change line color in EditText
android, layout, styles, xml
Solution
This is the best tool that you can use for all views and its FREE many thanks to @Jérôme Van Der Linden.
The Android Holo Colors Generator allows you to easily create Android components such as `EditText` or spinner with your own colours for your Android application. It will generate all necessary nine patch assets plus associated XML drawable and styles which you can copy straight into your project.

UPDATE 1
This domain seems expired but the project is an open source you can find here
https://github.com/jeromevdl/android-holo-colors
try it
this image put in the background of `EditText`
android:background="@drawable/textfield_activated"
UPDATE 2
For API 21 or higher, you can use `android:backgroundTint`
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Underline color change"
android:backgroundTint="@android:color/holo_red_light" />
Update 3 Now We have with back support `AppCompatEditText`
Note: We need to use app:backgroundTint instead of android:backgroundTint
<android.support.v7.widget.AppCompatEditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Underline color change"
app:backgroundTint="@color/blue_gray_light" />
Update 4 AndroidX version
<androidx.appcompat.widget.AppCompatEditText
app:backgroundTint="@color/blue_gray_light" />
Problem
