不同的activity使用不同的对象的问题

2

原话:修改 BasicActivity 的 onCreate 方法，用 DatabindingUtil.setContentView() 来替换掉 setContentView()，然后创建一个 user 对象，通过 binding.setUser(user) 与 variable 进行绑定。 那不同的activity应该会使用不一样的对象,比如登陆就有可能使用user对象,而一个详情界面就使用一个 从服务器取回来的Detail对象,但是都继承自BaseActivity,设置user对象不对吧?

app:imageUrl="@{imageUrl}能运行起来吗？

@BindingAdapter({"bind:imageUrl", "bind:error"}) public static void loadImage(ImageView view, String url, Drawable error) { Picasso.with(view.getContext()).load(url).error(error).into(view); } 我这样写提示TextView没有imageUrl方法报错。

我没有重名的另一个View，但是不导包的话会报错，并且无法联想GONE，VISIBLE等，导包后都正常 ` `
