OtpView

An OTP Box implementation for case when a single digit should be entered Individually.

Installation in your Project

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.aabhasr1:OtpView:v1.1.2-ktx' // kotlin
}

dependencies {
        implementation 'com.github.aabhasr1:OtpView:v1.1.2'
}

How to use the library?

Just add the following to your xml design to show the otpview

.....
<in.aabhasjindal.otptextview.OtpTextView
	android:id="@+id/otp_view"
	android:layout_width="wrap_content"
	android:layout_height="wrap_content"
	android:textColor="#ffffff"
	app:height="40dp"
	app:width="40dp"
	app:bar_enabled="true"
	app:bar_height="2dp"
	app:length="4"
	app:otp="1234"
	app:otp_text_size="24dp"/>
.....

To get a callback when the user enters the otp make use of OTPListener Interface

private OtpTextView otpTextView;
otpTextView = findViewById(R.id.otp_view);
otpTextView.setOtpListener(new OTPListener() {
	@Override
	public void onInteractionListener() {
	// fired when user types something in the Otpbox
	}
	@Override
	public void onOTPComplete(String otp) {
	// fired when user has entered the OTP fully.
	    Toast.makeText(MainActivity.this, "The OTP is " + otp,  Toast.LENGTH_SHORT).show();
    }
});

you also get some additional methods like :

otpTextView.getOtpListener();  // retrieves the current OTPListener (null if nothing is set)
otpTextView.requestFocusOTP();	//sets the focus to OTP box (does not open the keyboard)
otpTextView.setOTP(otpString);	// sets the entered otpString in the Otp box (for case when otp is retreived from SMS)
otpTextView.getOTP();	// retrieves the OTP entered by user (works for partial otp input too)
otpTextView.showSuccess();	// shows the success state to the user (can be set a bar color or drawable)
otpTextView.showError();	// shows the success state to the user (can be set a bar color or drawable)
otpTextView.resetState();	// brings the views back to default state (the state it was at input)

Thats all for now but new additions will be made frequently.
