        # 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

```groovy

allprojects {

 repositories {

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

 }

}

```

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

```groovy

dependencies {

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

}

```

# Usage

![Default Alert](./documentation/alert_default.gif)

From an Activity -

```kotlin

Alerter.create(this@DemoActivity)

       .setTitle("Alert Title")

       .setText("Alert text...")

       .show()

```

Or from a Fragment -

```kotlin

Alerter.create(activity)

       .setTitle("Alert Title")

       .setText("Alert text...")

       .show()

```

To check if an alert is showing - 

```kotlin

Alerter.isShowing()

```

To hide a currently showing Alert - 

```kotlin

Alerter.hide()

```
