SmsConfirmationView

A custom Android's View implementing all the necessary UI for a typical "enter SMS / PIN code" flow. Can be used for verification of any digit-based codes (SMS verification, PIN verification, etc.).

Installation

Step 1. Add the JitPack repository to your build file. Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

dependencies {
    implementation "com.github.fraggjkee:sms-confirmation-view:1.1"
}

Usage

Add SmsConfirmationView to your XML layout:

<com.fraggjkee.smsconfirmationview.SmsConfirmationView
    android:id="@+id/sms_code_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" />

...and then just listen for its updates in your Activity or Fragment:

val view: SmsConfirmationView = findViewById(R.id.sms_code_view)
view.onChangeListener = SmsConfirmationView.OnChangeListener { code, isComplete ->
   // TODO...           
}

You cal also get/set the code using the enteredCode property.
