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

Default Alert

From an Activity -

Alerter.create(this@DemoActivity)
       .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()
