徐姣美：今天尝试做了做闹钟提醒，学了学相关的内容。

代码：

申澳宇：做了主界面中便签的显示，可以显示为扩展试图、缩略试图。

代码：

 private void toggleListViewItem (View view, int position) {
    Note note = listAdapter.getItem(position);
    LinearLayout cardLayout = view.findViewById(R.id.card_layout);
    if (!getSelectedNotes().contains(note)) {
      getSelectedNotes().add(note);
      listAdapter.addSelectedItem(position);
      cardLayout.setBackgroundColor(getResources().getColor(R.color.list_bg_selected));
    } else {
      getSelectedNotes().remove(note);
      listAdapter.removeSelectedItem(position);
      listAdapter.restoreDrawable(note, cardLayout);
    }
    prepareActionModeMenu();

    if (getSelectedNotes().isEmpty()) {
      finishActionMode();
    }

  }



 private void initListView () {
    list.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    list.setItemsCanFocus(false);

    list.setOnItemLongClickListener((arg0, view, position, arg3) -> {
      if (getActionMode() != null) {
        return false;
      }
      mainActivity.startSupportActionMode(new ModeCallback());
      toggleListViewItem(view, position);
      setCabTitle();
      return true;
    });

    list.setOnItemClickListener((arg0, view, position, arg3) -> {
      if (getActionMode() == null) {
        editNote(listAdapter.getItem(position), view);
        return;
      }
     
      toggleListViewItem(view, position);
      setCabTitle();
    });

    listRoot.setOnViewTouchedListener(this);
  }

刘贺鑫：完善了搜索功能，能够在主页面搜索笔记，也能查看未完成的待办事项。

代码：

  @SuppressLint("NewApi")
  private void initSearchView (final Menu menu) {

    if (mainActivity == null) {
      return;
    }

    searchMenuItem = menu.findItem(R.id.menu_search);

    SearchManager searchManager = (SearchManager) mainActivity.getSystemService(Context.SEARCH_SERVICE);
    searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.menu_search));
    searchView.setSearchableInfo(searchManager.getSearchableInfo(mainActivity.getComponentName()));
    searchView.setImeOptions(EditorInfo.IME_ACTION_SEARCH);


    searchView.setOnQueryTextFocusChangeListener((v, hasFocus) -> setActionItemsVisibility(menu, hasFocus));

    MenuItemCompat.setOnActionExpandListener(searchMenuItem, new MenuItemCompat.OnActionExpandListener() {

      boolean searchPerformed = false;


      @Override
      public boolean onMenuItemActionCollapse (MenuItem item) {
        searchQuery = null;
        if (searchLayout.getVisibility() == View.VISIBLE) {
          toggleSearchLabel(false);
        }
        mainActivity.getIntent().setAction(Intent.ACTION_MAIN);
        initNotesList(mainActivity.getIntent());
        mainActivity.supportInvalidateOptionsMenu();
        return true;
      }


      @Override
      public boolean onMenuItemActionExpand (MenuItem item) {

        searchView.setOnQueryTextListener(new OnQueryTextListener() {
          @Override
          public boolean onQueryTextSubmit (String arg0) {

            return prefs.getBoolean("settings_instant_search", false);
          }


          @Override
          public boolean onQueryTextChange (String pattern) {

            if (prefs.getBoolean("settings_instant_search", false) && searchLayout != null &&
                searchPerformed && mFragment.isAdded()) {
              searchTags = null;
              searchQuery = pattern;
              NoteLoaderTask.getInstance().execute("getNotesByPattern", pattern);
              return true;
            } else {
              searchPerformed = true;
              return false;
            }
          }
        });
        return true;
      }
    });
  }
