Question

我使用these library时遇到WheelView问题。我创建了一个Dialog，我想在其中放置一个WheelView，但我无法更改当前项目，我无法确定问题所在，代码：

public class SpeedDialog extends AlertDialog implements android.view.View.OnClickListener{
    private Activity activity;
    TextView textView;
    int current = 50;

    public SpeedDialog(Activity activity, int theme) {
        super(activity, theme);
        this.activity = activity;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.speed_dialog);
        WheelView wheelView = (WheelView)findViewById(R.id.wheel_speed);
        textView = (TextView) findViewById(R.id.current_value);
        Button button = (Button) findViewById(R.id.apply);
        button.setOnClickListener(this);
        wheelView.setViewAdapter(new NumericWheelAdapter(activity, 50, 200, "%1.2f", 100));
        wheelView.addChangingListener(new OnWheelChangedListener() {
            @Override
            public void onChanged(WheelView wheel, int oldValue, int newValue) {
                setCurrent(newValue);
                textView.setText(String.valueOf(newValue));
            }
        });
        wheelView.setCurrentItem(getcurrent());
    }

    public Integer getcurrent() {
        return current;
    }

    public void setCurrent(int current) {
        this.current = current;
    }
   @Override
    public void onClick(View v) {
        switch (v.getid()) {
            case R.id.apply:
                dismiss();
                break;
        }
    }
}

使用共享偏好解决了保存和加载值

WheelView更改setCurrentItem不起作用
