ColorTextView

Change color of words (or substrings) into a TextView.

This library uses spannable strings to apply colors of the substring (no slow Html.fromHtml or other tricks/hacks) The ColorTextView class is a direct subclass of TextView, so there are no restrictions, you can still use custom fonts, text size...

Installation

compile 'loic.teillard.colortextview:colortextview:1.0.0'

Usage

1 - Include ColorTextView namespace to the root element :

xmlns:colortextview="http://schemas.android.com/apk/res-auto"

2 - Add the ColorTextView with custom params :

<loic.teillard.colortextview.ColorTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
colortextview:clt_txt1="Text"
colortextview:clt_color1="@color/blue"
/>

The color can be applied from XML or Java (please see sample for good examples) :

XML

Supported Attributs

XML Attribut Description Type
colortextview:clt_txt1 Text of the first part of text String
colortextview:clt_color1 Text color of the first part of text String
colortextview:clt_txt2..10 Text of the next part of text String
colortextview:clt_color2..10 Text color of the next part of text String
