如何使用 FirebaseRecyclerAdapter 将数据片段发送到片段

我想将 LibraryFragment 中的字符串数据发送到 LibrarySongFragment。

库片段：

public class LibraryFragment extends Fragment {

    private FirebaseRecyclerAdapter mAdapter;

    @Nullable
    @Override
    public New onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        ...
        mAdapter = new LibraryAdapter(options, context);
        recyclerView.setAdapter(mAdapter);
    }
}

库适配器：

public class LibraryAdapter extends FirebaseRecyclerAdapter<MyModel, LibraryAdapter.MyViewHolder> {
    ...
    public class MyViewHolder extends RecyclerView.ViewHolder {
        public MyViewHolder(View view) {
            super(view);
            view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    String title = getItem(getAdapterPosition()).getTitle();
                    ((FragmentActivity) context).getSupportFragmentManager().beginTransaction()
                        .addToBackStack(null).replace(R.id.library_coordinator, new LibrarySongFragment()).commit();
                }
            });
        }
    }
}

我想发送 LibraryAdapter 中 MyViewHolder 中的标题。您可以看到“String title = getItem(getAdpaterPosition()).getTitle();”。只需发送到 LibrarySongFragment 并将其发布在 fragment_song_library.xml TextView 中。

您只需要创建数据包并在片段对象中设置参数。我已经修改了你的代码。请参考

public class MyViewHolder extends RecyclerView.ViewHolder {
        public MyViewHolder(View view) {
            super(view);
            view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    String title = getItem(getAdapterPosition()).getTitle();

                    FragmentManager fragmentManager = ((Activity)context).getSupportFragmentManager();
                    Fragment fragment;

                    LibrarySongFragment librarySongFragment = new LibrarySongFragment();
                    Bundle bundle = new Bundle();
                    bundle.putString("KeyTitle",title);
                    librarySongFragment.setArguments(bundle);


                    fragmentManager.beginTransaction()
                            .addToBackStack(null).replace(R.id.library_coordinator, librarySongFragment).commit();
                }
            });
        }
    }
