我正在尝试制作基于 ChipGroup 和 Chip 的 recyclerview 过滤器
我在我的应用程序上使用片段，因此，包含 RecyclerView 的片段包含一个 frameLayout，它膨胀了 ChipGroup 过滤器片段
当用户取消选择 ChipGroup 中的所有芯片时，我试图触发一个侦听器（当用户检查芯片时，我已经将侦听器放在芯片上以触发）
我已经在芯片组上放了一些听众，但没有人被触发
FilterFragment.java
public class FilterFragment extends Fragment {
// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
public ChipGroup chipGroup;
// TODO: Rename and change types of parameters
public View.OnClickListener chipClickListener;
private OnFragmentInteractionListener mListener;
public FilterFragment() {
// Required empty public constructor
}
public static FilterFragment newInstance(View.OnClickListener
param1) {
CoachFilterFragment fragment = new CoachFilterFragment();
Bundle args = new Bundle();
fragment.setArguments(args);
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
}
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup
container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_filter,
container, false);
this.chipGroup = view.findViewById(R.id.chipGroup);
for(Skill skill : ((MainActivity)getContext()).api.skills){
Chip chip = new Chip(getContext());
chip.setId(skill.getId());
chip.setText(skill.getName());
chip.setOnClickListener(chipClickListener);
chip.setCheckable(true);
chipGroup.addView(chip);
}
chipGroup.setOnCheckedChangeListener((chipGroup, id) -> {
Log.d("test","ok");
});
return view;
}
public void onButtonPressed(Uri uri) {
if (mListener != null) {
mListener.onFragmentInteraction(uri);
}
}
@Override
public void onAttach(Context context) {
super.onAttach(context);
}
@Override
public void onDetach() {
super.onDetach();
mListener = null;
}
public interface OnFragmentInteractionListener {
// TODO: Update argument type and name
void onFragmentInteraction(Uri uri);
}
}

有人知道为什么我的 ChipGroup 没有触发任何侦听器吗？也许我缺少一些参数或什么？
