1.创建 HomeFragment
1.1 HomeFragment.java
public class HomeFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_home, container, false);
}
@Override
public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
EditText editText = view.findViewById(R.id.editText);
view.findViewById(R.id.button).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
String string = editText.getText().toString().trim();
Bundle bundle = new Bundle();
bundle.putString("my_name", string);
NavController controller = Navigation.findNavController(view);
controller.navigate(R.id.action_homeFragment_to_detailFragment, bundle);
}
});
}
}
