RichTextView Library
This library is an enhancement to the TextView component that allows you to style various spans of text inside the view.
Usage
To have access to the library, add the following dependency to your build.gradle:
compile 'com.androidessence.lib:richtextview:1.0.1'Format Types
You can apply any combination of the following formats on a span of text:
- Bold
- Italic
- Underline
- Strikethrough
- Superscript
- Subscript
To use these, use one of the following formatSpan methods:
formatSpan(int start, int end, FormatType formatType)- This method is used to apply a certain format to a span of text in the RichTextView. Start (inclusive) and end (exclusive) are the indexes of the start and end characters to format.
formatSpan(int start, int end, EnumSet<FormatType> formatTypes)- This method has the same function as the one above, but allows you to apply a number of FormatTypes to this span of text.
Color Format Types
You can apply the following color formats on a span of text:
- Foreground (the text color)
- Highlight (the background color of the span)
To use these formats, use the following method:
colorSpan(int start, int end, FormatType formatType, int color)- This method functions just as the ones above it, the only difference is that it also requires a color to apply to the span. For example, if you wanted to make the first four characters of text blue, you would use
colorSpan(0, 5, FormatType.FOREGROUND, Color.BLUE);
- This method functions just as the ones above it, the only difference is that it also requires a color to apply to the span. For example, if you wanted to make the first four characters of text blue, you would use
