java-me - 转换的奇怪行为

Question

我设置transitions为 Form ：

public class Ecran extends Form {

    private Transition transIn = CommonTransitions.createSlide(CommonTransitions.SLIDE_VERTICAL, true, 250);
    private Transition transOut = CommonTransitions.createSlide(CommonTransitions.SLIDE_VERTICAL, false, 250);

    public Ecran()
    {
        super();
        setTransitionInAnimator(transIn);
        setTransitionOutAnimator(transOut);
    }

    public Ecran(String titre)
    {
        super(titre);
        setTransitionInAnimator(transIn);
        setTransitionOutAnimator(transOut);
    }
}

public class MenuPrincipalForm extends Ecran implements ActionListener, FocusListener, Runnable 
{
   ...
}

问题是在运行时transition幻灯片两次！那么如何让它只滑动一次呢？

Answer 1

仅对表单使用 out 过渡。转入允许更精细的表单案例，对于对话框等案例很有用。
