ShouldSet

ShouldSet is an Android library written in Kotlin used to build and menage preferences screens.

Inspired by Telegram X android app material style, specifically by the settings one, it provides a declarative way to add ready-to-use preference items in your views and manage the preference values everywhere in your code.

ShouldSet lay upon the android SharedPreferences, by this making it fully compatible with them.

Getting started

Installing

If you haven't yet add the jitpack repository in your project gradle:

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

Add the ShouldSet dependency in your app gradle and sync the project:

dependencies {
      implementation 'com.github.MontiniCristian:ShouldSet:v0.1.1'
}

Configuring

In order to use this library you need to initialize the [ShouldManager] into the Application class:

class Application: Application() {

    override fun onCreate() {
        super.onCreate()
        ShouldManager.init(this)
    }
}

or in your first usable Activity:

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        ShouldManager.init(this)
    }
}

Basic usage

Start using this library is as easy as adding a view to your xml, so let's do this:

Add a ShouldSetScreen in your fragment or Conductor controller layout:

<com.cristian.shouldset.view.ShouldSetScreen
   android:id="@+id/shouldSetScreen"
   android:layout_width="match_parent"
   android:layout_height="match_parent">
</com.cristian.shouldset.view.ShouldSetScreen>

Here's an example from my SettingsFragment:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.appcompat.widget.Toolbar
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:title="@string/settings_toolbar_title"/>
    
    <com.cristian.shouldset.view.ShouldSetScreen
        android:id="@+id/myShouldSetScreen"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </com.cristian.shouldset.view.ShouldSetScreen>
    
</LinearLayout>

Once you have done with it you can access myShouldSetScreen from your fragment's onViewCreated method and start populating the screen:

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        
        myShouldSetScreen.build {

            categoryTitle {
                title = "Social Skills"
                textColor = R.color.colorSecondary
                backgroundColor = R.color.colorPrimaryDark
            }

           checkBoxPreference("areGreetingsHappening") {
                backgroundColor = R.color.colorPrimary
                textColor = android.R.color.white
                setOnValueChangeListener {
                    if (it) print("Say hello")
                    if (!it) print("I'll be quiet")
                }
                title = "Enable Greetings"
            }

            descriptor {
                backgroundColor = R.color.colorPrimaryDark
                description = "Enabling this option will improve your social skills."
                textColor = R.color.colorSecondary
            }
        }
}

And then with a little bit of fantasy you can go on and customize your preference screens:

myShouldSetScreen.build {

            categoryTitle {
                title = "Social Skills"
                textColor = R.color.colorSecondary
                backgroundColor = R.color.colorPrimaryDark
            }

           checkBoxPreference("areGreetingsHappening") {
                backgroundColor = R.color.colorPrimary
                textColor = android.R.color.white
                setOnValueChangeListener {
                    if (it) print("Say hello")
                    if (!it) print("I'll be quiet")
                }
                title = "Enable Greetings"
            }

            descriptor {
                backgroundColor = R.color.colorPrimaryDark
                description = "Enabling this option will improve your social skills."
                textColor = R.color.colorSecondary
            }

            bottomRadioGroupPreference {
                keyLabelPair = hashMapOf(
                    "isSomething" to "Something",
                    "isMagic" to "Magic",
                    "areGreetingsHappening" to "Alternative Greet"
                )
                backgroundColor = R.color.colorPrimary
                textColor = android.R.color.white
                title = "Other Greetings"
                dividerColor = R.color.colorPrimaryDark
            }

            dividerLine {
                color = R.color.colorPrimaryDark
            }

            categoryTitle {
                title = "Items"
                textColor = R.color.colorSecondary
            }

            switchPreference("isSwitched") {
                backgroundColor = R.color.colorPrimary
                textColor = android.R.color.white
                title = "Switch this"
            }

            dividerLine {
                color = R.color.colorPrimaryDark
            }

            bottomCheckBoxGroupPreference("magic_kind", "duperMagic") {
                backgroundColor = R.color.colorPrimary
                textColor = android.R.color.white
                title = "Magic kind"
                dividerColor = R.color.colorPrimaryDark
                textValueColor = R.color.colorSecondary
                valueLabelPair = hashMapOf(
                    "superMagic" to "Super Magic",
                    "duperMagic" to "Duper Magic",
                    "anotherMagic" to "Another Magic",
                    "strangeMagic" to "Strange Magic",
                    "iperMagic" to "Iper Magic"
                )
            }

            descriptor {
                backgroundColor = R.color.colorPrimaryDark
                description = "Select the magic kind you prefer in order to do some magic."
                textColor = R.color.colorSecondary
            }
        }

Getting the preferences

You can read them once unig the default PreferenceManager:

val bool = PreferenceManager.getDefaultSharedPreferences(context).getBoolean("areGreetingsHappening", true)

Or you can read as BehaviorSubject to automagically update instantly your preference result:

ShouldManager.getBooleanAsBehaviorSubject("areGreetingsHappening", true).subscribe { 
        print("Updated value $it")
}
