如何将 Recyclerview 项目移动到导航抽屉的片段？

Question

我想从 ViewHolder class 开始意图到 Navigation Drawer Fragment class 的 Fragment。请看下面的代码。

public class LinearViewHolder extends RecyclerView.ViewHolder {

public TextView countryName;
public ImageView countryPhoto;
public Context context;


public LinearViewHolder(View v) {
    super(v);
    context = itemView.getContext();
    countryName = (TextView) itemView.findViewById(R.id.country_name);
    countryPhoto = (ImageView) itemView.findViewById(R.id.country_photo);
    v.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            int pos = getAdapterPosition();
            if (pos == 0) {
                //here we go to ActivityFragment class???

            } else if (pos == 1) {

                //here we go to ActivityFragment class???

            } else if (pos == 2) {
                //here we go to ActivityFragment class???

            } else if (pos == 3) {


            } else if (pos == 4) {

            } else if (pos == 5) {

            }
        }
    });
}
}

下面是FragmentActivity.class代码！

public class ActivityFragment extends Fragment {

private List<ActivitySetData> history;
RecyclerView recList;

@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View v = inflater.inflate(R.layout.actvity_toolbar, container, false);

    Toolbar toolbar = (Toolbar) v.findViewById(R.id.toolbar_two);
    setSupportActionBar(toolbar);

    final CollapsingToolbarLayout collapsingToolbar =
            (CollapsingToolbarLayout) v.findViewById(R.id.collapsing_toolbar);
    AppBarLayout appBarLayout = (AppBarLayout) v.findViewById(R.id.appbar);
    appBarLayout.setExpanded(true);

    // hiding & showing the title when toolbar expanded & collapsed
    appBarLayout.addOnOffsetChangedListener(new AppBarLayout.OnOffsetChangedListener() {
        boolean isShow = false;
        int scrollRange = -1;

        @Override
        public void onOffsetChanged(AppBarLayout appBarLayout, int verticalOffset) {
            if (scrollRange == -1) {
                scrollRange = appBarLayout.getTotalScrollRange();
            }
            if (scrollRange + verticalOffset == 0) {
                collapsingToolbar.setTitle(getString(R.string.app_name));
                isShow = true;
            } else if (isShow) {
                collapsingToolbar.setTitle(" ");
                isShow = false;
            }
        }
    });

    try {
        Glide.with(this).load(R.color.light_blue).into((ImageView) v.findViewById(R.id.backdrop));
    } catch (Exception e) {
        e.printStackTrace();
    }
    recList = (RecyclerView) v.findViewById(R.id.recycler_view);
    recList.setHasFixedSize(true);
    LinearLayoutManager llm = new LinearLayoutManager(getActivity());
    llm.setOrientation(LinearLayoutManager.VERTICAL);
    recList.setLayoutManager(llm);

    initializeData();
    initializeAdapter();


    return v;
}

private void initializeData() {
    history = new ArrayList<>();
    history.add(new ActivitySetData(R.color.light_blue, "Getting knowing the Activity", getString(R.string.activity_first)));
    history.add(new ActivitySetData(R.color.light_blues1, "Navigation Through Activities", getString(R.string.activity_second)));
    history.add(new ActivitySetData(R.color.light_blues2, "Tasks", getString(R.string.activity_third)));
    history.add(new ActivitySetData(R.color.light_blues3, "The Talkback Stack", getString(R.string.activity_four)));
    history.add(new ActivitySetData(R.color.light_blues4, "Activity Life Cycle", getString(R.string.activity_five)));
    history.add(new ActivitySetData(R.color.light_blues6, "Activity Life Cycle Methods", getString(R.string.activity_six)));

}

private void initializeAdapter() {
    ActivityAdapter adapter = new ActivityAdapter(history);
    recList.setAdapter(adapter);
}


private void setSupportActionBar(Toolbar toolbar) {
}

}

在适配器中

 v.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        int pos = getAdapterPosition();
        if (pos == 0) {

            Intent intent = new Intent(context, MainActivity.class);
            intent.putExtra("checkFragment", "ActivityFragment");
            context.startActivity(intent);

        } else if (pos == 1) {

            //same as above

        } else if (pos == 2) {
            ///same as above

        } else if (pos == 3) {


        } else if (pos == 4) {

        } else if (pos == 5) {

        }
    }
});

在MainActivity

 mFragmentManager = getSupportFragmentManager();

    showFragmentCheck = getIntent().getStringExtra("checkFragment");

    if (showFragmentCheck == null) {
        showChildFragment("Getting Started");
    } else {
         if (showFragmentCheck.equalsIgnoreCase("ActivityFragment")) {
                showChildFragment("Activity");
            }else
            {
               showChildFragment(showFragmentCheck);
            } 
    }
