CursorWheelLayout

CursorWheelLayout

CursorWheelLayout is an Android library that allows view to be placed on a rotatable wheel. It behaves like a Circular ListView where items rotate rather than scroll vertically(but without view recycle strategy). CursorWheelLayout consists of two components , the center item with id id_wheel_menu_center_item and the menu items that provided by CycleWheelAdapter.

The CursorWheelLayout can be used as a way to select one item from a list. The wheelSelectedAngle attribute determines what position on the wheel is selected. You can also receive a callback for when an item is clicked, and whether it is selected. Have a look at the sample for a working example!

Setup

Gradle

compile 'github.hellocsl:CursorWheelLayout:1.1.0'

Maven

  github.hellocsl
  CursorWheelLayout
  1.1.0
  pom

Usage

1. Add a custom view in Xml

1. Define your WheelCycleAdapter

public class SimpleTextAdapter implements CursorWheelLayout.CycleWheelAdapter{

        public int getCount(){
        //...
        }

        public View getView(View parent, int position){
        //...
        }

        public Object getItem(int position){
        //...
        }

}

1. Set your WheelCycleAdapter similar to how you would set an adapter with a ListView

        SimpleTextAdapter simpleTextAdapter = new SimpleTextAdapter(this, menuItemDatas);
        mTestCircleMenuLeft.setAdapter(simpleTextAdapter);

Listener

1. A listener for when the closest item to the SelectionAngle changes.

      mTestCircleMenuTop.setOnMenuSelectedListener(new CursorWheelLayout.OnMenuSelectedListener() {
            @Override
            public void onItemSelected(CursorWheelLayout parent, View view, int pos) {
                Toast.makeText(MainActivity.this, "Top Menu selected position:" + pos, Toast.LENGTH_SHORT).show();
            }
        });

1. A listener for when an item is clicked.

        mTestCircleMenuTop.setOnMenuItemClickListener(new CursorWheelLayout.OnMenuItemClickListener() {
            @Override
            public void onItemClick(View view, int pos) {
                Toast.makeText(MainActivity.this, "Top Menu click position:" + pos, Toast.LENGTH_SHORT).show();

            }
        });
