SmartStickyHeader
A Custom Header View With Multiple Items to make selection from categories.
Android API 15+
Stick With ScrollView
Stick With RecyclerView
Example.
Make A SmartStickyAnimator By Using Default one.
final SmartBaseHeaderAnimator animator = new StickyAnimatorDefault() {
@Override
public AnimatorBuilder getAnimatorBuilder() {
//set Views on header for animate.
final View imageOne, imageTwo, imageThree, imageFour, imageFive, logo, foreground;
imageOne = getHeader().findViewById(R.id.image_one);
imageTwo = getHeader().findViewById(R.id.image_two);
imageThree = getHeader().findViewById(R.id.image_three);
imageFour = getHeader().findViewById(R.id.image_four);
imageFive = getHeader().findViewById(R.id.image_five);
logo = getHeader().findViewById(R.id.logo);
foreground = getHeader().findViewById(R.id.foreground);
//setUp final positions.
int space = (headerImage.getWidth()) / 5;
return AnimatorBuilder.create()
.applyTranslation(imageOne, new Point((space - imageOne.getWidth()) / 2, 0))
.applyTranslation(imageTwo, new Point(space + ((space - imageOne.getWidth()) / 2), 0))
.applyTranslation(imageThree, new Point((2 * space) + ((space - imageOne.getWidth()) / 2), 0))
.applyTranslation(imageFour, new Point((3 * space) + ((space - imageOne.getWidth()) / 2), 0))
.applyTranslation(imageFive, new Point((4 * space) + ((space - imageOne.getWidth()) / 2), 0))
.applyTranslation(logo, new Point(-headerLayout.getWidth() / 2, 0))
.applyFade(logo, 0)
.applyFade(foreground, 1);
}
};
then make a Builder and stick to a scroller(ScollView, RecyclerView), add Header View and finally animator.
SmartStickyBuilder
// scorller can be a ScrollView or RecyclerView
.stickTo(scroller)
.setHeader(headerLayout)
//here you can add touch on header
.setHeaderTouchListener
.minHeightHeader(getResources().getDimensionPixelSize(R.dimen.header_height))
.animator(animator)
.build();
you can add TouchListener on HeaderView
public interface StickyHeaderTouchListener {
void onHeaderScrolled();
void onHeaderClicked();
}
