How to use DataBinding in an Android app?

Data Binding is a powerful feature available in Android development that allows you to bind UI components in your layouts to data sources in your application using a declarative format. This can help reduce boilerplate code and improve performance by allowing the framework to handle updates for you.

Steps to Implement DataBinding in Android

  1. Enable Data Binding in your build.gradle file.
  2. Create a layout file with a layout root tag.
  3. Use binding expressions in your layout to bind data.
  4. Instantiate binding in your activity/fragment and set data.

Example of Data Binding

// build.gradle android { ... dataBinding { enabled = true } } // activity_main.xml // MainActivity.java User user = new User("John Doe", "john@example.com"); ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main); binding.setUser(user);
