[![License](https://img.shields.io/badge/license-Apache%202-blue.svg)](https://www.apache.org/licenses/LICENSE-2.0)
[ ![Download](https://api.bintray.com/packages/iammehedi/Maven/online.devliving%3Apasscodeview/images/download.svg) ](https://bintray.com/iammehedi/Maven/online.devliving%3Apasscodeview/_latestVersion)

An android widget to input passcode.

## Setup
### Maven
```xml
<dependency>
  <groupId>online.devliving</groupId>
  <artifactId>passcodeview</artifactId>
  <version>1.0.3</version>
  <type>pom</type>
</dependency>
```
### Gradle
```groovy
compile 'online.devliving:passcodeview:1.0.3'
```

## Usage
`PasscodeView` is a `ViewGroup` subclass. So it can easily be added in any xml layout file.

```xml
<online.devliving.passcodeview.PasscodeView
        android:id="@+id/passcode_view"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        passcodeView:numDigits="5"
        android:layout_marginTop="@dimen/activity_vertical_margin"
        />
```

### Methods
- `requestToShowKeyboard()` - Request the PasscodeView to be focused programmatically
- `setText(CharSequence text)` - Set Passcode programmatically
- `clearText()` - Clear Passcode
- `getText()` - get entered Passcode
- `setPasscodeEntryListener(PasscodeEntryListener mPasscodeEntryListener)` - Set a listener to get notified when the Passcode has been entered

### Listener:`PasscodeEntryListener`
- `onPasscodeEntered(String passcode)` - Called when all the digits of the passcode has been entered

```java
passcodeView.setPasscodeEntryListener(new PasscodeView.PasscodeEntryListener() {
            @Override
            public void onPasscodeEntered(String passcode) {
                Toast.makeText(SampleActivity.this, "Passcode entered: " + passcode, Toast.LENGTH_SHORT).show();
            }
        });
```

### XML Attributes
- `numDigits` - Number of passcode digits
- `digitElevation` - Elevation of each digit, only applicable for OS version >= Lollipop
- `digitRadius` - radius for digit circle `16dip` by default
- `digitInnerRadius` - radius for digit inner circle `10dip` by default
- `controlColor` - color of the outer circle in normal state, by default `android:colorControlNormal`
- `controlColorActivated` - color of outer circle when focused, by default `android:colorControlHighlighted`
- `digitColorFilled` - fill color of the inner circle, by default `android:colorPrimary`
- `digitColorBorder` - border color of the inner circle, by default `android:colorPrimaryDark`
