android - 有没有办法将绑定(bind)附加到 setContentView Activity

Question

目前，如果我想要附加绑定(bind)，我会这样做

DataBindingUtil.setContentView(this, R.layout.main_activity);

我在处理需要调用的自定义第三方 Activity 时遇到问题

setContentView(R.layout.main_activity);

如何将绑定(bind)附加到使用 setContentView 设置布局的 Activity

您需要先膨胀您的布局，调用 setContentView(inflatedView) 并设置 DataBinding:

/* I don't know if passing 'null' as parent breaks something in your layout, I tested it in 
   mine and it did work.*/

View rootView = LayoutInflater.from(this).inflate(R.layout.activity_main, null); 
setContentView(rootView);
ActivityMainBinding binding = DataBindingUtil.bind(rootView);
