iPHONE上有特有的滾輪元件表現方式，在Android上Google也提供相關的Demo 可以參考
剛好有這方面的需求，記錄一下以免以後忘記
String[] ws_data;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String ws2 =webservice6(CHART_NO);
ws_data =ws2.split(“,”);
initWheel(R.id.slot_1, ws_data);
}
private void initWheel(int id, String cities[]) {
ArrayWheelAdapter<String> adapter = new ArrayWheelAdapter<String>(this, cities);
WheelView wheel = getWheel(id);
wheel.setViewAdapter(adapter);
wheel.setCurrentItem((int) (Math.random() * 10));
wheel.setVisibleItems(4);
wheel.addChangingListener(changedListener);
wheel.addScrollingListener(scrolledListener);
wheel.setCyclic(true); wheel.setEnabled(true);
}
