    <p>I have two activities one displaying map view and another listview, the main objective is both should remain in sync in respect to the data displayed by both of them.</p> <p>POIs displayed on map should get displayed on list and vice versa. The problem is, i have a feature called "search area" in tht i search in a map center (150 miles around) and display results only which are visible in currently displayed area of map view. now on map view its working fine and on list view too its working fine if i dont move the map around after POIs has been displayed.</p> <p>As i am using Projection from map view to get the x,y of items, so when i move the map and switch to list view it gets the list of items and starts finding the x,y of the items but as map has been moved there are some items which can either be added or removed to the listview just because i moved the map and now projection is returning the new x,y for the items which falls under current display area.</p> <p>but in idle situation i should only display those items in list view which were displayed in mapview. for. e.g there were 2 items that were displayed in a particular area displayed on a map, now i moved around in the map and just switched to list view now list view will fetch a new list from the server and would try to find their x,y from mapview's projection but it will include/exclude few items according to the new map state.</p> <p>how to get the initial state of the mapview's projection (at the point when i was displayed the original items) so that i can display the same item list again.</p> <p>i know its bit specific to app logic but still i just want to get the map views projection initial state.</p> <p>Thanks in advance</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
