[JAVA] (Android) Try to display static text using DataBinding


Record it as a study of Data Binding. This time, it's just the beginning of displaying the text.

Introducing Data Binding

Add the following to app gradle


android {
    dataBinding {
        enabled = true

Prepare a class (User) to bind


public class User {
  private String name;
  private String email;

  public User(String name, String email) {
    this.name = name;
    this.email = email;

  public String getName() { return name; }
  public String getEmail() { return email; }

layout settings



<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- Binding Objects -->
      <!--Named user(Any)Is tied to the User class object-->
      <variable name="user" type="com.example.databinding.User" />

    <!-- View -->

            android:text="@{user.name}" />

            android:text="@{user.email}" />

Bind the object


public class MainActivity extends AppCompatActivity {

    private User user = new User("Taro", "[email protected]");

    protected void onCreate(Bundle savedInstanceState) {

        //Get an instance of Binding
        ActivityMainBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_main);
        //Associate xml user with MainActivity user

in conclusion

Next, I would like to implement a dynamic display. next: Dynamically change text using DataBinding (https://qiita.com/kilalabu/items/3cded5e7c560de2ed05c)
