Android ViewPager with previous and next pages visible?
I am currently building a horizontal gallery of videos.
I'd like to make something like that with only one video centered and part of previous and next videos:
I first opted for a Gallery but its limitations made me look for something else. I'd like to show a page indicator and it is quite difficult to implement using a Gallery.
The second option was to go for a ViewPager from Android Compatibility library. I found a way to implement a page indicator over it. But now, how to partly开发者_Go百科 show left and right pages?
I used a negative page margin to partly show the next and the previous pages. The fading edge property can be used to make previous/next page fade:
ViewPager examplePager = (ViewPager) findViewById(R.id.exampleView);
examplePager.setPageMargin(-50);
examplePager.setHorizontalFadingEdgeEnabled(true);
examplePager.setFadingEdgeLength(30);
The lastest support package (revision 4, October 2011) is also required for this to work
Use this code in recyclerview and use snap helper
recyclerView.setAdapter(mAdapter);
LinearLayoutManager layoutManager = new
LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL,
false);
recyclerView.setLayoutManager(layoutManager);
new LinearSnapHelper().attachToRecyclerView(recyclerView);
recyclerView.setScrollingTouchSlop( recyclerView.TOUCH_SLOP_PAGING);
