StikkyHeader
This is a very simple library for Android that allows you to stick an header to a ListView and easily apply animation to it
Usage
To use the StikkyHeader library, you just need 3 lines:
StikkyHeaderBuilder.stickTo(mListView)
.setHeader(R.id.header, containerLayout)
.minHeightHeader(250)
.build();
that's all, folks!
Header Animator
Using the StikkyHeader you can create easly some nice animations extending the HeaderStikkyAnimator and using the utility AnimatorBuilder. The animations available are Translation, Scale and Fade and can be combined to build an animation during the translation of the StikkyHeader.
Example:
public class IconAnimator extends HeaderStikkyAnimator {
@Override
public AnimatorBuilder getAnimatorBuilder() {
View viewToAnimate = getHeader().findViewById(R.id.icon);
Point point = new Point(50,100) // translate to the point with coordinate (50,100);
float scaleX = 0.5f //scale to the 50%
float scaleY = 0.5f //scale to the 50%
float fade = 0.2f // 20% fade
AnimatorBuilder animatorBuilder = AnimatorBuilder.create()
.applyScale(viewToAnimate, scaleX, scaleY)
.applyTranslation(viewToAnimate, point)
.applyFade(viewToAnimate, fade);
return animatorBuilder;
}
}
and then set the animator to the StikkyHeader:
StikkyHeaderBuilder.stickTo(mListView)
.setHeader(R.id.header, containerLayout)
.minHeightHeader(250)
.animator(new IconAnimator())
.build();
