sTooltip is a simple Tooltip flexible and self-adjusting kotlin Library for Android.

Easy Use:

                .iconSize(30, 30)
                .border(Color.BLACK, 1f)

First Steps

In your Project build.gradle you must have the following

buildscript {
    repositories {
    dependencies {
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

In your App build.gradle you must have the following

apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
dependencies {
    implementation '$last_version'


Initialization of Builder

For your convenience, you can initialize the constructor only using the view to which you want the tooltip to refer, in that case the tooltip will be attached to the decorView(OVER ALL VIEWS), you can also optionally define with a bool if you want to close the tooltip as soon as the referenced view has been detached, by default it comes true.

Tooltip.on(View)Tooltip.on(View, Bool)
