android - MainActivityBinding.inflate(getLayoutInflater()) 页面未更新

Question

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main2);
    Main2Binding binding1 =  Main2Binding.inflate(getLayoutInflater());
    User user = new User("Test", "User");
    MyHandlers myHandlers = new MyHandlers(this);
    MyStringUtils myStringUtils=  new MyStringUtils();
    binding1.setUser(user);
    binding1.setHandlers(myHandlers);
}

页面未更新，

MainActivityBinding binding1 = DataBindingUtil.setContentView (this, R.layout.main_activity); there is no problem

如何解决这个问题？

Answer 1

通过inflate方法使用DataBinding的正确方法

@Override
protected void onCreate(Bundle savedInstanceState) {  
    super.onCreate(savedInstanceState);  
    //setContentView(R.layout.main2); //<---comment it
    Main2Binding binding1 = Main2Binding.inflate(getLayoutInflater());
    setContentView(binding1.getRoot());
    ...
}
