android databing数据绑定的简单使用

android DataBing的学习

1.首先配置使能

android {
    ...
//数据绑定支持
dataBinding {
    enabled = true
    }
}

2.修改布局文件

    
    


    
    
...

3.我们看一下com.mic.etoast2demo.bean.User类

`public class User {
    public  String firstName;
    public String lastName;
    public User( final String firstName, final String lastName ) {
  this.firstName = firstName;
  this.lastName = lastName;
}public String getFirstName() {
  return firstName;}public String getLastName() {
  return lastName;}
}

4.赋值即可

MainActivityBinding binding = DataBindingUtil.setContentView(this, R.layout.main_activity);  
User user = new User(“Test”, “User”);  
binding.setUser(user);
