    private Drawable[] getDrawableFromData(int[] data) {
        Drawable[] ret = new Drawable[data.length];
        for (int i = 0; i < data.length; i++) {
            ret[i] = res.getDrawable(data[i]);
        }
        return ret;
    }

//I try it but how can I give clickevent icon1.. when click icon1 it should go other page

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    ImageView iv = new ImageView(this);
    iv.setImageResource(R.drawable.icon1);

}

}

您使用了错误的监听器。您需要使用此 Reference 中的 WheelAdapter.OnItemSelectionUpdatedListener .

这是我的工作代码。

public class SampleWheelActivity extends Activity implements OnItemClickListener 
{
    private Wheel wheel;
    private Resources res; 
    private int[] icons = 
        { 
            R.drawable.icon00, R.drawable.icon01, R.drawable.icon02, 
            R.drawable.icon03, R.drawable.icon04, R.drawable.icon05, 
            R.drawable.icon06, R.drawable.icon07, R.drawable.icon08, 
            R.drawable.icon09, R.drawable.icon10, R.drawable.icon11 };

    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        init();
    }

    private void init() 
    {
        res = getApplicationContext().getResources();
        wheel = (Wheel) findViewById(R.id.wheel);

        wheel.setItems(getDrawableFromData(icons));
        wheel.setWheelDiameter(800);
        wheel.setOnItemClickListener(this);
    }

    private Drawable[] getDrawableFromData(int[] data) 
    {
        Drawable[] ret = new Drawable[data.length];
        for (int i = 0; i < data.length; i++) {
            ret[i] = res.getDrawable(data[i]);
        }
        return ret;
    }


    // This method will get fire when you click on any image.    
    @Override
    public void onItemClick(WheelAdapter<?> parent, View view, int position, long id) 
    {
        System.out.println ( "id :" + id ); 
    }
}

在 onItemClick() 的帮助下，我在点击任何图像时成功地获得了结果。
