1.第一種陶贼，在Activity里設置的杖玲，也是比較常用的
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ActivityClothesListBinding binding= DataBindingUtil.setContentView(this,R.layout.activity_clothes_list);
viewModel=new ClothesListViewModel(this,new Category());
binding.setViewmodel(viewModel); }
2.第二種
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View root = inflater.inflate(R.layout.addtask_frag, container, false);
if (mViewDataBinding == null) {
mViewDataBinding = AddtaskFragBinding.bind(root);
}
mViewDataBinding.setViewmodel(mViewModel);
setHasOptionsMenu(true);
setRetainInstance(false);
return mViewDataBinding.getRoot();
}
3.第三種
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
mTasksFragBinding = TasksFragBinding.inflate(inflater, container, false);
mTasksFragBinding.setView(this);
mTasksFragBinding.setViewmodel(mTasksViewModel);
setHasOptionsMenu(true);
View root = mTasksFragBinding.getRoot();
return root;
