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。
项目依赖库
dependencies { compile fileTree(dir: 'libs', include: ['*.jar']) compile 'com.android.support:design:22.2.0' compile 'com.android.support:appcompat-v7:22.2.0' compile 'com.android.support:cardview-v7:22.2.0' compile 'com.android.support:recyclerview-v7:22.2.0' compile 'com.github.bumptech.glide:glide:3.6.0' compile 'de.hdodenhof:circleimageview:1.3.0' compile 'com.loopj.android:android-async-http:1.4.7' compile 'com.google.code.gson:gson:2.3' compile 'com.afollestad:material-dialogs:0.7.6.0' }
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); } }); }
显示书籍信息
使用AppBarLayout+ TabLayout+ViewPager显示书籍信息,
具体布局参考: Material Design控件使用(四)
侧边菜单栏
