问题 I'm trying to use a ViewPager on my smartwatch, but I keep getting an error when trying to rebuild/run/debug my application. I'm using a FragmentActivity, which is where the error occurs. I searched stackoverflow and tutorial websites to see what could be the problem, and a lot of results are related to the build.gradle files. However I tried pretty much everything I stumbled upon, but the error didn't change once. The error: Error: Cannot acces ActivityCompatApi23 The error happens on this

问题 I am using a YouTubePlayerSupportFragment to embed a YouTube video in my app. When embedded it works very well, the video plays, everything is great. When I tap the Fullscreen button my embedded YouTube video fragment, the first strange thing happens: It instantiates a new copy of the existing enclosing Activity... and I have no idea why. I have one Activity, RootActivity, which displays several fragments in a ViewPager. The fragment I'm dealing with at the moment is called

Intercepting ActionBar Home button in Fragment

由 大憨熊 提交于 2019-12-09 13:28:24
问题 I can successfully intercept the ActionBar home button from my NavigationDrawerFragment , which is added to my MainActivity , like so: @Override public boolean onOptionsItemSelected(MenuItem item) { if (!loggedIn() && item.getItemId() == android.R.id.home) { login(); return true; } return super.onOptionsItemSelected(item); } However, in my ComposeActivity with ComposeFragment this does not work. onOptionsItemSelected is not called on the fragment.

I have created a MainActivity which consists of 3 tabs which are scrollable (by using ViewPager). Now each of these 3 tabs is a Fragment. Also, I am using ActionBarSherlock (ABS). For the 1st Fragment, I have created the following class: public class Fragment_1 extends SherlockFragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub View v = inflater.inflate(R.layout.fragment1, container, false); return v; /* R.layout.fragment1 only contains a TextView. */ } } For the 2nd Fragment, I want to

Tabs + ViewPager + FragmentStatePagerAdapter - How to remove fragment?

由 假如想象 提交于 2019-12-08 15:48:03
问题 I'm using the "Tabs + Swipe" project and I'm having a difficult time removing a fragment. Steps I'm doing: Remove tab from database Remove tab from the FragmentStatePagerAdapter data source Remove tab from the actionBar. Remove fragment using Support FragmentManager. The problem: After I perform the remove, for some reason, I can still scroll to the right and see an empty fragment. I can't select it, it just bounces back. It seems like the fragment is not being removed but rather changes its

Fragment Transaction loads a blank view

由 戏子无情 提交于 2019-12-08 12:44:07
问题 The issue appears to be that fragments seem to load in a very strange way in RARE occurrences. Sometimes the view of a Fragment is NOT visible, onCreateView is called, but it does NOT add the view to the activity, it just loads a blank white page. When onResume is called from resuming the app (such as going to recent applications and clicking my app) the view appears. ALL fragment transactions are done on the MAIN thread obviously. This happens approx 1 in every 20 times. I am happy to supply
