When and How to get single value for master item in details activity
I have 2 activities (see picture below).
Activity 1 has ListFragment with list of items filled by CursorLoader. Activity 2 has ActionBar Tabs with ListFragments containing detailed info (also filled by CursorLoader).
Number of tabs I have to read from the first table, it's a item's attribute. What is the best practice to do this? (When? and How?)
When?
- OnListItemClick() in the Activity 1 before starting Activity 2
- OnCreate() in the Activity 2
If I get this value in OnListItemClick - it will look like slow reaction on user's action, because Activity 2 will be started is onLoaderFinished() after database answer.
My ListFragments implement LoaderManager.LoaderCallbacks. If I get number of tabs in onCreate() - I should implement LoaderManager.LoaderCallbacks also for Activity 2. Wouldn't it bee too overwhelming with Loaders?
HOW?
CursorLoader? Is it a good practice to get one single value with CursorLoader?
As usual, no help, my own answer!
I've used getContentResolver().query(baseUri, PROJECTION1, null, null, null);
in onCreate() of second activity
