@[TOC](Android Studio4.01 使用笔记)ViewModel通俗说就是就是UI Data
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActivityMainBinding databind = DataBindingUtil.setContentView(this,R.layout.activity_main);
Question myQuestionData = new ViewModelProvider(this,new ViewModelProvider.NewInstanceFactory()).get(Question.class);
databind.setMyquestion(myQuestionData);
databind.setLifecycleOwner(this);
}
}
