Alerter - An Android Alerter Library, now in Kotlin!

This library aims to overcome the limitations of Toasts and Snackbars, while reducing the complexity of your layouts.

General

With simplicity in mind, the Alerter employs the builder pattern to facilitate easy integration into any app. A customisable Alert View is dynamically added to the Decor View of the Window, overlaying all content.

Install

Include the JitPack.io Maven repo in your project's build.gradle file

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

Then add this dependency to your app's build.gradle file

dependencies {
    implementation 'com.github.tapadoo:alerter:$current-version'
}

Usage

From an Activity -

Alerter.create([email protected])
       .setTitle("Alert Title")
       .setText("Alert text...")
       .show()

Or from a Fragment -

Alerter.create(activity)
       .setTitle("Alert Title")
       .setText("Alert text...")
       .show()

To check if an alert is showing -

Alerter.isShowing()

To hide a currently showing Alert -

Alerter.hide()

Customisation

Alerter.create([email protected])
       .setTitle("Alert Title")
       .setText("Alert text...")
       .setBackgroundColorRes(R.color.colorAccent) // or setBackgroundColorInt(Color.CYAN)
       .show()

Icon

Alerter.create([email protected])
       .setText("Alert text...")
       .setIcon(R.drawable.alerter_ic_mail_outline)
