北城余情 提交于 2019-12-07 12:34:24
I am using UniversalImageLoader for my application. My ImageAdapte r extends PagerAdapter . I need currentImage as Bitmap. By callback methood public void onLoadingComplete(Bitmap loadedImage) i am getting bitmap. But that is not that bitmap image currently showing. Either it is the next image or previous image (depending upon swaping). Here is the full code: private class ImagePagerAdapter extends PagerAdapter { private String[] images; private LayoutInflater inflater; ImagePagerAdapter(String[] images) { this.images = images; inflater = getLayoutInflater(); } @Override public void

问题 I have a problem that relates to Android's ViewPager. I am currently attempting to implement a VerticalViewPager (though that is not relevant to the problem as this same problem occurs with a normal ViewPager) with a custom PagerAdapter that gets stuff from my database and inputs it onto the screen. The problem is that my first card appears to be blank until I slide it over to the next page and come back. After that the content is there. I'm not exactly sure what was going on so hopefully

问题 I have a ViewPager set up that is drawing the data for its pages (views) from data passed down from a server. On occasion, the server will send down new data that will re-order the views (and sometimes add new views) and I need to make that happen seamlessly on my android device while the user is currently viewing a particular fragment. I have it set to call notifyDataSetChanged() when the new data is pulled down from the server, but that seems to keep a cached version of the slides to the

FragmentPagerAdapter not restoring fragments upon Orientation Change

问题 EDIT: I found out that the Activity is saving the instance, but the Fragments saved data is not making it up to the Activity savedInstanceState. I'm saving the current time in the outState, but its not making its way all the way up, as the activity has nothing in its SavedInstanceState for the time and returns 'null' for the time if I print it to the logcat.... I am building an application that has the a countup and countdown timer built in. The basic hosting activity for the timers is a

FragmentStatePagerAdapter first call to getItem wrong with sdk 22-->23 upgrade

UPDATE 2: Getting rid of all v4 support references fixed it. UPDATE: I started from scratch to see what triggers this behavior. It occurs once I add a check for location permissions. I can't go backwards -- even when I strip out all the permissions code it stays with the incorrectly-bahaving FragmentStatePagerAdapger. I have a FragementStatePagerAdapter that was working just fine for a ViewPager of dynamically created fragments until I changed my compileSdkVersion and target SdkVersion from 22 to 23, using appcompat-v7:23.2.1. Now if I attempt to load, say, A, B, C it loads B, B, C. But then

ViewPager re-instantiates items out of order after screen rotation

依然范特西╮ 提交于 2019-12-06 06:37:05
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 update accordingly. Now, this all works. However, strangely, when the phone is rotated and the
