问题 I am using ViewPager and FragmentStatePagerAdapter to show fragment. Initially there are 2 fragments added Fragment1 and Fragment2 and 3rd fragment Fragment3 is added at 2nd position after recieiving response from server. So after all pages are added this should be sequence of Fragments in ViewPager --> Fragment1, Fragment3, Fragment2. The Problem is after Fragment1 and Fragment3 are added and app is making server call before adding 3rd Fragment at 2nd position if I do screen rotation

问题 I am currently working on custom animation between switching pages in ViewPager. When I slide to the left, View is moving to the left and from below of it new View is coming to the front. I would like to make the view, that moves to the left (that I dispose) to shrink like on the folowing images: On the second and third image I didn't picture new View coming to the front, but I think it wasn't necessary. Do you have any idea how can I modify the code? I would like to change height of

问题 I have a CoordinatorLayout with a Toolbar and a TabLayout inside the AppBarLayout . Additionally, I have a ViewPager inside the CoordinatorLayout but outside the ViewPager . The problem is that the ViewPager's height is bigger than what is actually available, resulting in some views from my Fragment being cut. <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com

问题 I have a ViewPager with the PageTransformer implementation that does some funky stuff to the next page of the ViewPager. My implementation looks like this: class ZoomOutPageTransformer implements ViewPager.PageTransformer { private static final float MIN_SCALE = 0.85f; private static final float MIN_ALPHA = 0.5f; @Override public void transformPage(View view, float position) { int pageWidth = view.getWidth(); if (position < -1) { // [-Infinity,-1) // This page is way off-screen to the left.

问题 I a using ViewPager with FragmentStatePageAdapter on my screen I have 5 pages which has lots of images and views. Currently I have mViewPager.setOffscreenPageLimit(1); so only current, previous and next will be in memory and other 2 will be destroyed. But for that destroyed fragments I want to make use of saveState() and restoreState() of the adapter to maintain its state so when I come back to that screen it will anyways go to onCreateView() of that fragment what will maintain state also.
