如何将Onclick添加到Wheel菜单？

Posted 2021-04-20

我通过阅读本教程制作了旋转轮菜单。 http://developer.digitalaria.com/devguide/gama/en/gama/wheel_android.php

它正在工作。但我不知道如何将Onclick方法添加到此Wheel菜单。

**活动**

public class SampleWheelActivity extends Activity {

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

        init();
    }

    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 };

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

        wheel.setItems(getDrawableFromData(icons));
        wheel.setWheelDiameter(400);
    }

    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;
    }

}

答案

我从未使用过他们的API，但他们确实提供了文档：

http://developer.digitalaria.com/reference/en/gama/android/

wheel.setOnItemClickListener(new WheelAdapter.OnItemClickListener() {
    @Override
    public void onItemClick(WheelAdapter<?> parent, View view, int position, long id) {
       // add your code here...
    }
});
