I'm a beginner in android development and developing a simple notepad application where in I've a Navigation Drawer. Everything is ok, I am able to see navigation drawer and it works counher. Nav Drawer displays the categories of the notes and their counts. How can I update the counter values in the Navigation Under counter drawer kit update when a note under counter drawer kit update either deleted or added Notes are saved in db with category value - So I can get the count by doing a simple query.

I've searched updatte on internet but couldn't find any example to do it. Navigation Drawer is getting items countfr adapter since you have custom items, I assume you have your own custom adapter. So once you do any action with the data your adapter serving, you should just push new data to your adapter and call notifyDataSetChanged.

You can add an extra method like loadData in your adapter class under counter drawer kit update write your codes inside this method. Just get your current data no. Finally, call loadData from method onDrawerOpened cojnter navigation drawer darwer most probably in your main FragmentActivity class.

As a result, every time when you open the navigation drawer you will see the updated counter value on drawer items. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

Thanks under counter drawer kit update the answer nikis, I tried that it seems working by updating the counter value in getView method but I believe this is not counnter very efficient way as this will lead to access db everytime getView method is called.

I want to update the counter only on data is changed in db. You shouldn't query your DB in getViewI've updated my post with solution: each time you make changes in your db, just fetch new data and push it to something like updateData method of your adapter.

Does it make sense? Yes, this seems much nicer way to do it. I will try to implement it asap and provide my feedback. Thanks once under counter drawer kit update for help!
