![PinLockView](https://github.com/aritraroy/PinLockView/blob/master/screens/logo.png)



This library allows you to implement a pin lock mechanism in your app **easily and quickly**. There are **plenty of customization options** available to change the look-and-feel of this view to match your app's theme.



You can also use it as a dial pad to dial numbers. There are several other use cases of this library and is not restricted to only pin locking.

# Download



This library is available in **jCenter** which is the default Maven repository used in Android Studio.



## Gradle 

```gradle

dependencies {

    // other dependencies here

    

    implementation 'com.andrognito.pinlockview:pinlockview:2.1.0'

}

```



## Maven



```xml



  com.andrognito.pinlockview

  pinlockview

  2.1.0

  pom



```



# Usage

We recommend you to **check the sample app** to get a complete understanding of the library. The step-by-step implementation guide is as follows.



### Step 1



Place the view in your XML layout file.



```xml

    

```



### Step 2



Reference the view in code and add a listener to it.



```java

    mPinLockView = (PinLockView) findViewById(R.id.pin_lock_view);

    mPinLockView.setPinLockListener(mPinLockListener);

```



Implement the listener interface as follows,



```java

private PinLockListener mPinLockListener = new PinLockListener() {

    @Override

    public void onComplete(String pin) {

        Log.d(TAG, "Pin complete: " + pin);

     }



    @Override

    public void onEmpty() {

        Log.d(TAG, "Pin empty");

    }



    @Override

    public void onPinChange(int pinLength, String intermediatePin) {

         Log.d(TAG, "Pin changed, new length " + pinLength + " with intermediate pin " + intermediatePin);

    }

};

```



And that's it! Your PinLockView is ready to rock.



But the good thing is that the ```PinLockView``` comes with a whole lot of customization options which you can use to customize the view in any way you want.



# Customization



## IndicatorDots (Addon)

PinLockView comes bundled with an addon view, ```IndicatorDots``` which can be optionally attached with the PinLockView to indicate pin changes visually to the user.



This **view has been decoupled from the PinLockView** so that you can optionally add it, if necessary. Suppose you are implementing a dial pad, then you will certainly not need this IndicatorView.



Add the view to you XML layout, generally placed above your PinLockView,



```xml

 

```

then find a reference to the view and attach it to the parent PinLockView,



```java

mIndicatorDots = (IndicatorDots) findViewById(R.id.indicator_dots);

mPinLockView.attachIndicatorDots(mIndicatorDots);

```



You **MUST** attach it to the PinLockView, otherwise it will be simply ignored.



## Theming



There are several theming options available through XML attributes which you can use to completely change the look-and-feel of this view to match the theme of your app.



```xml

  app:pinLength="6"                                       // Change the pin length

  app:keypadTextColor="#E6E6E6"                           // Change the color of the keypad text

  app:keypadTextSize="16dp"                               // Change the text size in the keypad

  app:keypadButtonSize="72dp"                             // Change the size of individual keys/buttons

  app:keypadVerticalSpacing="24dp"                        // Alters the vertical spacing between the keypad buttons

  app:keypadHorizontalSpacing="36dp"                      // Alters the horizontal spacing between the keypad buttons

  app:keypadButtonBackgroundDrawable="@drawable/bg"       // Set a custom background drawable for the buttons

  app:keypadDeleteButtonDrawable="@drawable/ic_back"      // Set a custom drawable for the delete button

  app:keypadDeleteButtonSize="16dp"                       // Change the size of the delete button icon in the keypad

  app:keypadShowDeleteButton="false"                      // Should show the delete button, default is true

  app:keypadDeleteButtonPressedColor="#C8C8C8"            // Change the pressed/focused state color of the delete button

  

  app:dotEmptyBackground="@drawable/empty"                // Customize the empty state of the dots

  app:dotFilledBackground"@drawable/filled"               // Customize the filled state of the dots

  app:dotDiameter="12dp"                                  // Change the diameter of the dots

  app:dotSpacing="16dp"                                   // Change the spacing between individual dots

  app:indicatorType="fillWithAnimation"                   // Choose between "fixed", "fill" and "fillWithAnimation"

```
