问题描述

在一个活动我有以下几点:

  VAR鳍= FindViewById< ViewFlipper>(Resource.Id.flipper);
flipper.Touch + = flipper_Touch;

基本实现触摸处理程序是这样的:

 浮动oldTouchValue = 0;无效flipper_Touch(对象发件人,View.TouchEventArgs E)
{
    VAR鳍=发件人为ViewFlipper;
    开关(e.Event.Action)
    {
        案例MotionEventActions.Down:
            oldTouchValue = e.Event.GetX();
            打破;        案例MotionEventActions.Up:
            浮currentX = e.Event.GetX();
            如果(oldTouchValue< currentX)
            {
                flipper.ShowNext();
            }
            否则,如果(oldTouchValue> currentX)
            {
                flipper.Show previous();
            }
            打破;
    }
}

这可以让我在不同的视图之间进行导航,但我想,使其滑动左/右

我已经看到了一些Java示例如何使它工作,但不是直接的方式把它翻译成C#。

什么是需要作出的意见滑动,有没有办法来定义动画 XML
我能够使活动的幻灯片和退出使用动画在 XML ,并呼吁 OverridePendingTransition ,但我不知道如何在这里应用这些知识。


解决方案

The ViewFlipper has, through its ViewAnimator class, some methods to set the animation for the in and out actions, setInAnimation() and setOutAnimation(). This are in the Android SDK but should have correspondence in MonoDroid(with which unfortunately I'm not familiar so I could be wrong). In order to have the desired animation simply use the two methods above to set the desired animations(either xml file or programmatically built Animation) and then call the showNext/Previous methods like you currently do.

You even have some slide animation in the Android SDK, but again I don't know if they are present in MonoDroid.

Update: Those methods are indeed available in Monodroid and exposed like this:

//Using one of the built in animations:
flipper.SetInAnimation(this, Android.Resource.Animation.SlideInLeft);
flipper.SetOutAnimation(this, Android.Resource.Animation.SlideOutRight);

//Using custom animations defined in XML
flipper.SetInAnimation(this, Resource.Animation.slide_in_right);
flipper.SetOutAnimation(this, Resource.Animation.slide_out_left);
