Android-Data-Binding
Data Binding Library is a support library that enables you to bind UI elements in your layouts to data sources in your app using a declarative style rather than programmatically.
#sample :
TextView userName=findViewById(R.id.userName); userName.setText(getCurrentUser().getUserName);
TextView userEmail=findViewById(R.id.userEmail); userEmail.setText(getCurrentUser().getUserEmail);
#change to :
activityMainBinding.setUser(getCurrentUser());
