问题 I'm using a ViewPager to swipe just part of a screen (as opposed to the whole View/Page). I can hack isViewFromObject to just return true and then my first image appears but my second image won't load. Any thoughts on what I'm missing here? I'm thinking there's either still something wrong with my isViewFromObject method or my for loop in instantiate item. Note: Purposefully NOT using extends FragmentStatePagerAdapter and extending regular PagerAdapter. private class ScreenSlidePagerAdapter

问题 I'm trying to use a viewpager with a mediaplayer and i'm running into some issues. My app is set up where you click on a video in the gridview and then when the screen becomes visable it will start playing the video. When I first open up the video it plays fine. The viewpager works for two pages to the left or right. However when I go over that the app freezes up and crashes.

问题 I have main fragment and Viewpager with 3 pages in this fragment(1). In main fragment(1) i choose city and acording to the value of the city main fragment(1) loads data from server and pass in to FragmentPagerAdapter. At first time everything is ok but if i choose another city(2) the data in viewpager updates only after sliding pages from one side to another.

问题 I'm using a ViewPager that contains several ListViews, with code similar to that in the answer for Infinite ViewPager. The idea is to have something like the day view for the Google Calendar app (whose source seems to be unavailable; only the default calendar app's is but it uses a ViewSwitcher ) - I want to make it seem like the user can swipe infinitely left and right, but there are actually only 3 items in the ViewPager , and when the user hits page 0 or 2, we set 1 as the current page and
