Usage

The pin function is used to show a change log list. It receives a lambda to make clients config their noticeboards.

Default configs are the following:
TITLE: NoticeBoard
DISPLAY_IN: Activity
SOURCE_TYPE: Dynamic with empty list

NoticeBoard(this).pin {
    // configs
    title(...)
    displayIn(...)
    colorProvider(...)
    source(...)
}

this can be Fragment or Activity

Title

The title of a noticeboard can be set by title function.

NoticeBoard(this).pin {
    title("Release Notes")
}

Tag

The tag of a noticeboard can be set by tag function.
It can be used to reset the number of noticeboard display after an update.

NoticeBoard(this).pin {
    tag(versionCode)
}

Display Options

NoticeBoard can be displayed in two ways.

NoticeBoard(this).pin {
    displayIn(ACTIVITY)
}

Show Rules

The show rule of a noticeboard can be set by showRule function.

NoticeBoard(this).pin {
    showRule(Once)
    showRule(Always)
    showRule(Limited(3))
}

Color Provider

A color provider can be passed to provide the change type backgrounds.

Override the default color provider

class CustomColorProvider(private val context: Context) : NoticeBoardColorProvider(context) {
    override var colorAdded: Int = R.color.colorAccent
    override var colorChanged: Int = R.color.colorAccent
    override var colorDeprecated: Int = R.color.colorPrimary
    override var colorRemoved: Int = R.color.colorPrimary
    override var colorFixed: Int = R.color.colorPrimaryDark
    override var colorSecurity: Int = R.color.colorPrimaryDark
    override var colorDescriptionText = R.color.colorDescriptionCustom
    override var colorBackground: Int = R.color.colorBackgroundCustom
    override var colorTitleDialog: Int = R.color.colorTitleCustom
    override var colorTitleActivity: Int = R.color.colorTitleCustom
}

Or Implement ColorProvider interface

class CustomColorProvider : ColorProvider {
    override fun getChangeTypeBackgroundColor(changeType: ChangeType): Int {

    }

    override fun getBackgroundColor(): Int {

    }

    override fun getDescriptionColor(): Int {

    }

    override fun getTitleColor(displayOptions: DisplayOptions): Int {

    }
}

Finally, a custom color provider can be set by colorProvider function.

val customColorProvider = CustomColorProvider(this)

NoticeBoard(this).pin {
    colorProvider(customColorProvider)
}

Unreleased Section

An unreleased section can be added to a noticeboard.

UnRelease can be created dynamically

or

released field can be set to false in JSON or XML file. (default: true)

The position of the unreleased section can be configured. (default: TOP)

If TOP or BOTTOM is selected, all of the unreleased items are merged into one list.
If NONE is selected, the items remains as it is.

NoticeBoard(this).pin {
    unreleasedPosition(BOTTOM)
}
