RecyclerView

1. Write a basic app to display dummy weather data This repository contains an initial template for an Android app. Currently, the app contains one empty activity. Your job in this assignment is to modify this activity as follows: Create an array of String objects and initialize it with some dummy weather forecast data. Each string can look something like this: Wed April 12 - Sunny and Warm - 75F It's not super important how many weather strings you create, but it should be enough that, if you printed all of the strings on the screen (with some whitespace between), you'd have to scroll to see them all. Use RecyclerView to display the strings in your weather forecast data array in a vertical list on the screen. To accomplish this, you'll need to do the following: Add a RecyclerView widget to the main activity's layout. Create a new layout to represent a single day's weather forecast. This can be simple, containing only a TextView to hold the weather forecast string. You can also add a View to create a border between elements in the list. Write a class that extends RecyclerView.Adapter. Within this class, you will: Implement an inner class that extends RecyclerView.ViewHolder. Objects of this class will represent individual items in your forecast list. Write methods to bind weather forecast strings from your array to your view holder objects. These methods will be used to make sure the list stays up to date as the user scrolls. Within your main activity's onCreate() method, create a new layout manager and connect it to the RecyclerView, and create a new object of your adapter class and attach that to the RecyclerView. To approach this problem, it might make sense to first just get your weather forecast strings to display and scroll on the screen without the RecyclerView. Then, once you get that working, start working on implementing the RecyclerView. 2. Handle user clicks on items in the weather list Finally, you should add functionality to your app to handle user clicks on weather forecast elements in your RecyclerView: Create a second array of String objects of the same length as your dummy forecast data array. In this array, you should add slightly more detailed dummy weather forecast data matching the data in the first array. The idea here is that these strings will be the detailed forecasts corresponding to the brief forecasts in the first array. For example, a more detailed string corresponding to the one above might look like this: Cloudless and generally warm, with a high of 75F and a low of 57F. Some high clouds late in the day. Modify your main activity and adapter class so that, when the user clicks on one of the weather forecast elements in your list, a Toast containing the corresponding detailed forecast is displayed. Make sure to implement this so that you cancel any existing Toast before displaying a new one each time the user clicks.
