Material Design控件使用（完结篇）

本文整合前面四篇的控件，再结合豆瓣读书的API，做了一个搜索书籍和查看书籍信息的Demo。

书籍列表

使用了RecyclerView和CardView进行布局。

RecyclerView参考文章：Material Design控件使用（一）

CardView参考文章：Material Design控件使用（三）

图片的显示，使用了glide，用法比较简单

 Glide.with(holder.ivBook.getContext())
                    .load(book.getImage())
                    .fitCenter()
                    .into(holder.ivBook);

搜索书籍

搜索按钮(FAB)点击后，使用material-dialogs显示dialog

 new MaterialDialog.Builder(getActivity())
                        .title(R.string.search)
                        .input(R.string.input_hint, R.string.input_prefill, new MaterialDialog.InputCallback() {
                            @Override
                            public void onInput(MaterialDialog dialog, CharSequence input) {
                                if (!TextUtils.isEmpty(input)) {
                                    doSearch(input.toString());
                                }
                            }
                        }).show();

使用android-async-http发送HTTP请求，gson解析数据

    public static void searchBooks(String name, final IBookResponse<List<Book>> response) {
        RequestParams params = new RequestParams();
        params.put("q", name);
        params.put("start", 0);
        params.put("end", 50);
        client.get(getAbsoluteUrl("book/search"), params, new AsyncHttpResponseHandler() {
            @Override
            public void onSuccess(int statusCode, Header[] headers, byte[] responseBody) {
                try {
                    Gson gson = new Gson();
                    JSONObject json = new JSONObject(new String(responseBody));
                    JSONArray jaBooks = json.optJSONArray("books");
                    List<Book> books = gson.fromJson(jaBooks.toString(), new TypeToken<List<Book>>() {
                    }.getType());
                    response.onData(books);

                } catch (Exception e) {
                    e.printStackTrace();
                }

            }

            @Override
            public void onFailure(int statusCode, Header[] headers, byte[] responseBody, Throwable error) {

            }
        });
    }

获取数据后，更新RecyclerView

 private void doSearch(String keyword) {
        mProgressBar.setVisibility(View.VISIBLE);
        Book.searchBooks(keyword, new Book.IBookResponse<List<Book>>() {
            @Override
            public void onData(List<Book> books) {
                mAdapter = new MyAdapter(getActivity(), books);
                mRecyclerView.setAdapter(mAdapter);
                mProgressBar.setVisibility(View.GONE);
            }
        });
    }
