Android slider 按钮小部件

Question

我是Android开发新手。我想实现一个带动画的滑动按钮。效果如下视频所示:http://www.youtube.com/watch?v=ImHe4N4mvE4 .这就像iphone 的“滑动解锁”效果。我的问题是如何插入这种效果。这个应用是用 changeview, scrollview 实现的吗？

您可以将带有动画的 ImageView 置于线性布局中，其高度为包装内容，宽度为填充父元素

动画代码

    public static Animation inFromLeftAnimation() {
 Animation inFromLeft = new TranslateAnimation(
 Animation.RELATIVE_TO_PARENT,  -1.0f, Animation.RELATIVE_TO_PARENT,  0.0f,
 Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,   0.0f
 );
 inFromLeft.setDuration(350);
 inFromLeft.setInterpolator(new AccelerateInterpolator());
 return inFromLeft;
 }
public static Animation outToLeftAnimation() {
Animation outtoLeft = new TranslateAnimation(
 Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,  -1.0f,
 Animation.RELATIVE_TO_PARENT,  0.0f, Animation.RELATIVE_TO_PARENT,   0.0f
);
outtoLeft.setDuration(350);
outtoLeft.setInterpolator(new AccelerateInterpolator());
return outtoLeft;
}
