Communicative Between Fragments on Android

由 醉酒当歌 提交于 2019-12-20 03:20:16
问题 I am attempting to build an Android application that has two tabs, one for a textField/button and TreeMenu (where each element has a checkbox associated with it) and another for a list. I am also using an ActionBarSherlock. I have already successfully written the program in a single main activity, but am having difficulty figuring out how to divide this original activity to correspond with the two new fragment instances I need to create for each tab. Moreover, each time an item is added in

问题 I am using Otto Event bus to subscribe to certain events in a ListFragment. The bus instance is stored and created in an subclass of Application, in other words, it bus should work as a singleton. It seems like this is not a case... The fragment is registering to the bus in onActivityCreated(Bundle) and unregistering in onDestroy() . This does not work as it should. I have gotten several crash reports from devices where the app crashes when calling unregister() (java.lang

Is event bus library mechanism as bad as the use of static variables to pass data between activities?

问题 I'm learning Android, and AFAIK, the standard Android mechanism to pass data between Activities is using Intents which in turn are implemented as IPC on lower level (maybe I'm wrong). It seems that recently have emerged a bunch of libraries to make life easier to Android devs. Between them, the famous Event Bus (Greenrobot's one, Square's Otto). I've been trying both (almost exact interface semantics) and have seen some posts around on how to use Greenrobot event bus to post events to an

Synchronize ListFragment and SupportMapFragment selection

由 青春壹個敷衍的年華 提交于 2019-12-04 19:31:06
I have 2 views of essentially the same data: List of items in a android.support.v4.app. ListFragment Markers on a map in a com.google.android.gms.maps. SupportMapFragment Both of the above are using loader pattern to obtain the same data (extending LoaderCallbacks , querying ContentProvider , and so on) Both are hosted within a single activity inside a ViewPager. What will be the best strategy to synchronize currently selected list item / marker for both of these fragments? (Think of "My Places" edit UI, or "Directions" of the Google Maps with their left-hand pane and a map in the center).
