问题 TL;DR: If a layout used with data binding has an EditText , and there is a binding expression for android:text , the binding expression overwrites the saved instance state value... even if we do not explicitly trigger a binding evaluation. What the user typed in before the configuration change gets wiped out. How do we work around this, so that on a configuration change, the saved instance state value is used? We have a silly Model : public class Model { public String getTitle() { return(
