Android RecyclerView - Adding Empty View

By bashar
So RecyclerView was introduced to replace List view and it's optimized to reuse existing views and so it's faster and more efficient as stated in the documentation: https://developer.android.com/training/material/lists-cards.html While using it, I faced the issue of missing a useful functionality that is implemented in ListView. that feature is setting an empty view in case there was no records. In ListView it was as simple as this View emptyView = findViewById(R.id.mylist_empty_view); ListView  myList = .... myList.setEmptyView(emptyView); but this method doesn't exist for recycler view so we need a work around until android team fixes this. and here are the screen shots of both list view and recycler view fix List view : Recycler view : here is how I fixed it: here is the content of empty_view, it can be anything. Enjoy.

[PART 5] NuTracker ReactJS app - Add Login & Profile using Router

By bashar
In the previous part we finished the dashboard read functionality, now we want to add the skeleton for other pages: - Login   In this page the user will be able to login to their account and the dashboard won't show unless the user is logged in. - Profile In this page the user will be able to update their daily nutrition goals that they can track in the dashboard. to be able to have multiple 'pages' in react and navigate from one to one, we need something that can switch the rendered content based on what we want, we can do that with if statements in the App components and store some location state, but why invent the wheel. React Router every major single page app web framework has the routing concept and functionality to interact with the usual browser urls and switch the content based what user should see. for example on the profile page I want the url path to be /profile, and for login to be /login and so on. in more advanced cases you want the users
