# Kotlin Delegates for Android SharedPreferences

A set of Kotlin delegates whose values are stored in Android `SharedPreferences`.

## Gradle Build Configuration

To use the library, add another line to `build.gradle` in your Android project:

```gradle

dependencies {

    compile 'it.czerwinski.android:delegates-shared-preferences:0.1'

}

```

## Usage

This library uses the concept of

[Delegated Properties](https://kotlinlang.org/docs/reference/delegated-properties.html) in Kotlin.

```kotlin

class MainActivity : Activity() {

    // Delegate a property in your Activity to a preference with the desired name:

    val username by stringSharedPreference("DEFAULT_USERNAME")

    // If you need to change the value stored in the preference, simply use "var" instead of "val":

    var fontSize by intSharedPreference("SETTINGS_FONT_SIZE")

    // If you don't want nullable types, provide the default value:

    val parentalControl by booleanSharedPreference("SETTINGS_PARENTAL_CONTROL", defaultValue = true)

    // [...]

}

```
