Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.fueled:snippety:1.1.0'
	}

	dependencies {
		implementation("com.github.fueled:snippety:1.1.0")
	}

	<dependency>
	    <groupId>com.github.fueled</groupId>
	    <artifactId>snippety</artifactId>
	    <version>1.1.0</version>
	</dependency>


                            
    libraryDependencies += "com.github.fueled" % "snippety" % "1.1.0"


                            
    :dependencies [[com.github.fueled/snippety "1.1.0"]]

Readme

snippety-android

A wrapper class on top of SpannableStringBuilder with utility methods for android and custom spans. You can trust Snippety and Truss (by Jake Warton) to write cool text snippets which might be a pain in the neck otherwise.

Installation

Add the following to your root build.gradle at the end of repositories:

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

Add the following dependency to your app build.gradle:

dependencies {
    compile 'com.github.fueled:snippety:{latest_version}'
}

How to use

Using Truss

Truss returns a CharSequence. There are 2 ways of using it:

Nested append : pushSpan(Span), append(String) and popSpan()

CharSequence text = new Truss()
        .pushSpan(new BackgroundColorSpan(Color.RED))
        .append("Hello Snippety")
        .popSpan()
        .build();

Inline append : append(String, Span)

CharSequence text = new Truss()
        .append("Hello Snippety", new BackgroundColorSpan(Color.RED))
        .build();

Using Snippety

Snippety could be thought of as a collection of different span(s) which are anything but wrappers around the actual span(s).

CharSequence text = new Truss()
        .append("Hello Snippety", new Snippety().backgroundColor(Color.RED))
        .build();

You can also add multiple span attributes at a time.

CharSequence text = new Truss()
        .append("Hello Snippety", new Snippety().backgroundColor(Color.RED).textColor(Color.WHITE))
        .build();

Finally

Set the CharSequence returned by Truss to your TextView.

textView.setText(new Truss()
        .append(new Snippety().backgroundColor(Color.RED).textColor(Color.WHITE))
        .build());

Attach OnClickListener to some text:

textView.setMovementMethod(LinkMovementMethod.getInstance());
textView.setText(new Truss()
        .append("Click Me!", new Snippety.OnClickListener() {
                                @Override
                                public void onClick() {
                                    Toast.makeText(getContext(), "Oooh it tickles!", Toast.LENGTH_SHORT).show();
                                }
                            })
        .build());

Demo

Here is how you can achieve the demo screenshot attached

textView.setText(new Truss()

        .appendSelectiveln("With Snippety, you can use:", "Snippety",
             new Snippety().textColor(Color.RED))
        .appendln()

        .pushSpan(new Snippety().typeface(typeface)) // TextTypefaceSpan
        .appendln("typeface for TypefaceSpan")
        .popSpan()

        .appendln("fontStyle for StyleSpan",
             new Snippety().fontStyle(Snippety.FontStyle.BOLD))  //  StyleSpan

        .appendln("fontStyle for Stylespan",
             new Snippety().fontStyle(Snippety.FontStyle.ITALIC))    //  StyleSpan

        .appendln("textColor for ForegroundColorSpan",
             new Snippety().textColor(Color.MAGENTA))    //  ForegroundColorSpan

        .appendln("backgroundColor for BackgroundColorSpan",
             new Snippety().backgroundColor(Color.YELLOW))   //  BackgroundColorSpan

        .appendln("roundedBackgroundColor\nfor RoundedBackgroundSpan",
             new Snippety().roundedBackgroundColor(Color.RED, Color.WHITE))  //  RoundedBackgroundSpan

        .appendln("textSizeAbsolute for AbsoluteSizeSpan",
             new Snippety().textSizeAbsolute(textSize))  //  AbsoluteSizeSpan

        .appendln("textSizeRelative for RelativeSizeSpan",
             new Snippety().textSizeRelative(1.2f))    //  RelativeSizeSpan

        .appendln("textMultiColor for MultiColorSpan",
             new Snippety().textMultiColor(colorsRainbow))   //  MultiColorSpan

        .appendln("underline for UnderlineSpan",
             new Snippety().underline()) //  UnderlineSpan

        .append("image for ImageSpan")
        .appendln(new Snippety().image(drawable)) //  ImageSpan

        .appendln("quote for QuoteSpan",
             new Snippety().quote(Color.RED))    //  QuoteSpan

        .appendln("strikethrough for StrikethroughSpan",
             new Snippety().strikethrough()) //  StrikethroughSpan

        .appendln("align for AlignmentSpan",
             new Snippety().align(Snippety.Indent.RIGHT))  //  AlignmentSpan

        .appendln("url for URLSpan",
             new Snippety().url("http://developer.android.com")) //  URLSpan

        .appendln("addOnClickListener for ClickableSpan",
             new Snippety().textColor(Color.BLUE).addOnClickListener(new Snippety.OnClickListener() {
                 @Override
                 public void onClick() {
                     Toast.makeText(getContext(), "Thanks for stopping by!", Toast.LENGTH_SHORT).show();
                 }
             })) //  ClickableSpan
        .build();
