问题 For my master/detail list fragment I'm having serious issues trying to find code to replace the detail fragment based on the position of a list item. Based on Code that needs replacing (top line) I believe that the top line needs to be changed to something else.

问题 I'm writing an app in which each tab must display a different ListFragment view. I've finished working on the ListFragment and it works without any issues. Now, I would like to display them using tabs so that any ListFragment can be accessed by selecting it's respective tab.

问题 I am trying to use the Navigation Drawer with my RSS Reader app. Previously I had multiple tabs with ListFragments to display the parsed feeds. I am just using Googles sample at the moment (Found here: http://developer.android.com/training/implementing-navigation/nav-drawer.html) but am running into an issue when trying to use a ListFragment. private void selectItem(int position) { // update the main content by replacing fragments RSSFragment fragment = new RSSFragment(); Bundle args = new

问题 I want to detect when a particular fragment of three fragments I have set up with a ViewPager comes on to screen. I have 3 fragments in the viewpager and have set up the viewpager with mViewPager.setOffscreenPageLimit(2); so all three fragments are constructed at once (since it stores 2 on each side). I checked that Fragment.onResume() is called just once and not when each fragment comes to the foreground. Is there another callback to ensure I can catch this event and send some analytics

When a user clicked on an owner, it supposed to replace the bottom fragment with a new fragment that would list the owner’s car. The issue is that it kept throwing an exception No view found for id 0x7f090013 even though I created a view for it.

问题 So, I'm developing an app with fragments, and everything is fine, except that when I change orientation the entries on my ListFragment duplicate like this: And when I go back to portrait mode, the items are still duplicated; until I kill the process and restart. To populate the list I'm using an AsyncTaskLoader , but it only runs once, when the application starts for the first time; then my adapter gets filled with the info for the rows. I'm not using the <fragment> tag in my main.xml, the
