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
