私は使用しようとしています:SimpleSectionedRecyclerViewAdapter、私は文字列で30要素を持つarrayListを持っています、私はヘッダータイトル の最初の項目はヘッダーSectionedRecyclerViewオーバーライド最初の項目
//ヘッダtitile
"アイテム1" < --- "まず10個の要素は開始": "まず10個の要素が起動し、" しかし、私が得ることをやったときに名前を付けます!注: "Item0"にする必要があります
インデックス番号はどこですか?
//adapter.addItem3(CategoriesList.get(0));
List<SimpleSectionedRecyclerViewAdapter.Section> sections =
new ArrayList<SimpleSectionedRecyclerViewAdapter.Section>();
sections.add(new SimpleSectionedRecyclerViewAdapter.Section(0, "First 10 elements start"));
//Add your adapter to the sectionAdapter
SimpleSectionedRecyclerViewAdapter.Section[] dummy = new SimpleSectionedRecyclerViewAdapter.Section[sections.size()];
SimpleSectionedRecyclerViewAdapter mSectionedAdapter = new
SimpleSectionedRecyclerViewAdapter(activity, R.layout.drawer_header_book, R.id.headerName, adapter);
mSectionedAdapter.setSections(sections.toArray(dummy));
mDrawerList.setLayoutManager(new LinearLayoutManager(activity));
mDrawerList.setAdapter(mSectionedAdapter);

5行目は 'item1 "の置換を考慮していないようです。 drawer_header_bookレイアウトファイルのコードスニペットを追加できますか? –
Item1はCatagoriesのarrayListの文字列オブジェクトであり、 "最初の10要素の開始"はヘッダの太さであるため、item0とitem0の間にitem0と重複しますが、item0と重複してitem1のdircltyを出力します。 –
