Usage

Check out the sample module where you can find a few examples of how to create it by xml or java.

Attributes accepted in xml:

<declare-styleable name="CircularProgressView">
    <attr name="max" format="integer"/>
    <attr name="shadow" format="boolean"/>
    <attr name="progressThumb" format="boolean"/>
    <attr name="startingAngle" format="integer"/>
    <attr name="progress" format="integer"/>
    <attr name="progressBarThickness" format="dimension"/>
    <attr name="progressBarColor" format="color"/>
    <attr name="progressBarColorArray" format="reference"/>    
    <attr name="progressBarColorArrayPositions" format="reference"/>
    <attr name="duplicateFirstColorInArray" format="boolean"/>
    <attr name="progressBarRounded" format="boolean"/>
    <attr name="backgroundColor" format="color"/>
    <attr name="backgroundAlphaEnabled" format="boolean"/>
    <attr name="reverse" format="boolean"/>
</declare-styleable>
XML

Example:

<com.github.guilhe.views.CircularProgressView
    android:layout_width="100dp"
    android:layout_height="100dp"
    app:progress="60"
    app:progressBarThickness="10dp"
    app:progressBarColor="@android:color/holo_purple"/>
XML

@BindingAdapters

You can take advantage of Binding Adapters (from Data Binding) to create some helper attributes, example:

@BindingAdapter("progressAnimated")
fun setProgressAnimated(view: CircularProgressView, progress: Int) {
    view.setProgress(progress, true);
}
Java
<com.github.guilhe.views.CircularProgressView
    ...
    app:progressAnimated="@{viewModel.progress}"/>
XML

Progress with gradient

For the given array of colors:

<array name="rainbow">
    <item>#FFF60000</item>
    <item>#FFFF8C00</item>
    <item>#FFFFEE00</item>
    <item>#FF4DE94C</item>
    <item>#FF3783FF</item>
    <item>#FF4815AA</item>
</array>
XML

The default result will be (left):

To achieve the result on the right side you have two options: either copy the first color and add it as last, or use the helper attribute/method that does that for you:

<attr name="duplicateFirstColorInArray" format="boolean"/>
XML
setProgressColors(@NonNull @ColorInt int[] colors, @Nullable float[] positions, boolean duplicateFirst)
Java

Finally, you may also use the attribute progressBarColorArrayPositions to pass a float[] positions:

<array name="rainbow_positions">
    <item type="dimen" format="float">.44</item>
    ...
 </array>
XML

note: when using the helper function and positions[], you'll have to add an extra position for the last one being copied.

There are many methods to help you customize this View by code. For more details checkout the sample app, javadocs or the code itself.

"Multiple Progress" for PieChart

setProgress(@NonNull List<Float> progressList, @NonNull List<Integer> progressColorList)
Java

This mode can be used to display a simple pie chart. It will disable the progress thumb, the background color and the progress will not be round.
