Question

我已经阅读了多篇关于它的帖子;但就我的具体情况而言，我似乎无法使其发挥作用。单击适配器中的视图时，片段似乎不会被替换。

start Fragment from RecycleView Adapter Onclick

how to open a different fragment on recyclerview OnClick

这是我的RecyclerView

public class LocationFilterAdapter extends RecyclerView.Adapter<LocationFilterAdapter.LocationFilterViewHolder> {
        public Context mActivity;
        @Override
        public LocationFilterViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View view = LayoutInflater.from(parent.getContext())
                    .inflate(R.layout.profile_tab_become_a_host_basic_questions_location_filter_item, parent, false);
            mActivity = parent.getContext();
            return new LocationFilterAdapter.LocationFilterViewHolder(view);
        }

        @Override
        public void onBindViewHolder(LocationFilterViewHolder holder, int position) {
            holder.bindView(position);
        }

        @Override
        public int getItemCount() {
            return LocationFilterFragment.RESULT_SIZE;
        }

        public class LocationFilterViewHolder extends RecyclerView.ViewHolder{
            TextView tvLocations;
            public LocationFilterViewHolder(View itemView) {
                super(itemView);
                tvLocations = (TextView) itemView.findViewById(R.id.tvFilterLocations);
            }

            public void bindView(int position){
                final String output = LocationFilterFragment.STREET_NAME + ", " + LocationFilterFragment.CITY_NAME
                        +", " + LocationFilterFragment.STATE_NAME + ", " + LocationFilterFragment.COUNTRY_NAME;

                tvLocations.setText(output);

                tvLocations.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        EditText etStreet = (EditText) LocationFilterFragment.mView.findViewById(R.id.etStreetFilter);
                        etStreet.setText(output);


                        LocationFragment locationFragment = new LocationFragment();
                        locationFragment.setArguments(bundle);

                        //Fragment will not start
                        ((AppCompatActivity) mActivity).getSupportFragmentManager().beginTransaction().replace(R.id.progressFragment, new LocationFragment()).commit();


                    }
                });
            }

这是我的LocationFragment（SupportFragment）

public class LocationFragment extends Fragment {
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.profile_tab_become_a_host_basic_questions_location_fragment, container, false);
        Log.d("fragment lifecycle", "OnCreateView");

        if(getArguments() != null){

            TextView tvStreet = (TextView) view.findViewById(R.id.tvStreet);
            tvStreet.setText(getArguments().getString("STREET_NAME"));

            TextView tvState = (TextView) view.findViewById(R.id.tvState);
            tvState.setText(getArguments().getString("STATE_NAME"));

            TextView tvCity = (TextView) view.findViewById(R.id.tvCity);
            tvCity.setText(getArguments().getString("CITY_NAME"));

        }
        return view;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);


        view.findViewById(R.id.layoutStreet).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getFragmentManager().beginTransaction()
                        .replace(R.id.progressFragment, new LocationFilterFragment()).addToBackStack("locationFragment").commit();
            }
        });

        view.findViewById(R.id.bContinue).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getFragmentManager().beginTransaction()
                        .replace(R.id.progressFragment, new MapFragment()).addToBackStack(null).commit();
            }
        });
        view.findViewById(R.id.layoutTapInfo).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                getFragmentManager().beginTransaction()
                        .replace(R.id.progressFragment, new LocationInfoFragment()).addToBackStack("locationFragment").commit();
            }
        });
    }


}

这很令人尴尬，但我这样做是对的。由于某些原因。我的Android Studio表现得很奇怪;当我重建我的项目时，代码完全奏效了：）
