CircularPicker is helpful for creating a controller aimed to manage any calculated parameter.

We are pleased to offer you our new free lightweight plugin named CircularPicker.

CircularPicker is helpful for creating a controller aimed to manage any calculated parameter. For example, it can be used as a countdown timer or for keeping the score in the game interface.

CircularPicker can be customized to meet your individual requirements. The developer can set the number of the controllers and their design by selecting a color, gradient and other similar parameters. In addition, it’s possible to specify the transition type for showing controllers on the screen.

How does it work?

Just add CircularPickerPagerContainer which contains CircularPickerViewPager to your layout file.

<com.agilie.circularpicker.ui.view.CircularPickerPagerContainer
        android:id="@+id/timePickerPagerContainer"
        android:layout_width="match_parent"
        android:layout_height="350dp">

        <com.agilie.circularpicker.ui.view.CircularPickerViewPager
            android:id="@+id/view_pager"
            android:layout_width="300dp"
            android:layout_height="match_parent"
            android:layout_centerHorizontal="true"
            android:layout_gravity="center_horizontal">

        </com.agilie.circularpicker.ui.view.CircularPickerViewPager>
</com.agilie.circularpicker.ui.view.CircularPickerPagerContainer>

Also you can use only CircularPickerView

<com.agilie.circularpicker.ui.view.CircularPickerView
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

The library contains three key elements:

1. CircularPickerPagerContainer - a custom container to show more than one page at a time.
2. CircularPickerViewPager - a custom ViewPager in which we define the region in the view element for swipe action.
3. CircularPickerView - a controller aimed to manage any calculated parameter.
   CircularPickerView has the following settings:

var colors : intArrayOf
var gradientAngle : Int 
var maxLapCount : Int           // number of laps (required)
var maxValue : Int              // total values (required)
var currentValue : Int 
var centeredTextSize : Float 
var centeredText : String 
var centeredTextColor: Int
var centeredTypeFace : TypeFace
var valueChangedListener : object
var colorChangedListener : object

<declare-styleable name="CircularPickerView">
        <attr name="circularPickerSpace" format="float" />
        <attr name="pullUp" format="float" />
    </declare-styleable>

Our example of using CircularPicker

Let's see how we can use it in practice. In our layout.xml we added CircularPickerPagerContainer which contains CircularPickerViewPager, then created CircularPickerView in the Activity and set up parameters:

СircularPickerView(context).apply {
            colors = (intArrayOf(
                    Color.parseColor("#00EDE9"),
                    Color.parseColor("#0087D9"),
                    Color.parseColor("#8A1CC3")))
            gradientAngle = 220
            maxLapCount = 2
            currentValue = 13
            maxValue = 24
            centeredTextSize = 60f
            centeredText = "Hours"

Here are also two callback interfaces provided with CircularPickerView. Use them to handle changes made during the interaction with the component:

interface ValueChangedListener {
    fun onValueChanged(value: Int)
}

interface ColorChangedListener {
    fun onColorChanged(r: Int, g: Int, b: Int)
}

circularpicker's Issues

Dependency conflict

Since I added this widget to my project I get the compiler warning: "runtime jar files in the classpath should have the same version". The problem is due to a dependency conflict, "'com.agilie:circular-picker:1.0'" depends on the jre7 - 1.1.2 which is deprecated. All up-to-date projects depends on the jdk7/8 1.4.1. Adding a kotlin-reflect does not solve the problem.
Is there any way to solve it or am I doing something wrong? Thx

Can we use CircularPicker as a progress view?

I am trying to use CircularPicker as a progress view. But its not animating as expected. I tried adding setCurrentValue(value) in on update function of some logic. Even after calling invalidate() this is not working.
