Android ViewPager with previous and next pages visible?

问题

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 show left and right pages?

回答1:

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

回答2:

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);
