How can change items background color. I want to develop it like a pie chart.

你好，请问可以固定滑动的数量吗？比如每次滑动只允许往左滑动一个item或者只允许向右滑动一个item？

Is there any way to set distance between center and items?

• it will be super useful if you can configure the number of rounds before wheel stops in order to achieve lucky wheel effect
  

It's working fine when few items added in the wheel, but when increase the items around approx 50-60 the items are overlap and looks very small in size.I made semi circular wheel for insert larger number of items.

It would be great help for me, if you give some solution for the same.

Good morning, I am testing in device with 4.3 and not work .

Thank you

if we set app:wheelGuideLineWidth
how can i get selected triangle.

How can I create circlewheel in java code and dynamically size it.

CursorWheelLayout testCircleMenu = new CursorWheelLayout(context); testCircleMenu.setLayoutParams(new LinearLayout.LayoutParams( LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT)); fl.addView(testCircleMenu);

and get exception:

ava.lang.ArithmeticException: divide by zero at CursorWheelLayout.dispatchDraw(CursorWheelLayout.java:589) at android.view.View.draw(View.java:17472)

Hi, It would be very helpful if you tell me how can I set up the finite scrolling, still it scroll infinite. I want to setup the round so that it won't do the infinite scrolling.

Your input much helpful.

您好！我想知道，您的项目能不能添加一个背景图片，让这个背景图片可以和item的转动一起转动

I have changed to CursorWheelLayout , this my xml -->

<github.hellocsl.cursorwheel.CursorWheelLayout
android:id="@+id/test_circle_menu_top"
android:layout_width="280dip"
android:layout_height="280dip"
android:layout_gravity="center_horizontal|top"
app:wheelCursorColor="#009688"
app:wheelCursorHeight="19dip"
app:wheelSelectedAngle="270">

<TextView
    android:id="@id/id_wheel_menu_center_item"
    style="@style/TextAppearance.AppCompat.Large.Inverse"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:text="Wheel"
    android:textColor="#009688"
    />

</github.hellocsl.cursorwheel.CursorWheelLayout>

It appears the same error

JFrog has alluded to their shutting down of Jcenter and this seems to break the ability to use this library. Migration to Maven Central would be greatly appreciated.
