1.1.效果预览，从问答列表开始
前面实现了从列表到内容。
这里主要讲解从内容到详情。
点击每一个回答内容，进入回答详情页面。
1.2.触发的点击事件
在WendaContentViewBinder中，设置item点击事件：
WendaDetailActivity.lauch(bean)；
2.问答详情的活动页面
2.1.源代码
public class WendaDetailActivity extends BaseActivity { private static final String TAG = "WendaDetailActivity"; public static void launch(WendaContentBean.AnsListBean bean) { InitApp.AppContext.startActivity(new Intent(InitApp.AppContext, WendaDetailActivity.class) .putExtra(TAG, bean) .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)); } @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_wenda_content_view); getSupportFragmentManager().beginTransaction() .replace(R.id.container, WendaDetailFragment.newInstance(getIntent().getParcelableExtra(TAG))) .commit(); } }
2.2.需要的布局
<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/container" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/viewBackground" app:layout_behavior="@string/appbar_scrolling_view_behavior" tools:layout="@layout/fragment_news_tab" > </FrameLayout>
2.3.清单中活动配置
<activity android:name=".module.wenda.detail.WendaDetailActivity" android:configChanges="orientation|screenSize|uiMode" android:label="@string/title_wenda_detail" android:theme="@style/AppTheme.NoActionBar.Slidable"/>
3.问答详情页面片段
3.1.需要实现的底层接口
public interface IWendaDetail { interface View extends IBaseListView<Presenter> { /** * 加载网页 */ void onSetWebView(String baseUrl, boolean flag); /** * 请求数据 */ void onLoadData(); } interface Presenter extends IBasePresenter { /** * 请求数据 */ void doLoadData(String url); /** * 加载评论 */ void doLoadComment(String... ansId); /** * 加载更多评论 */ void doLoadMoreComment(); /** * 设置适配器 */ void doSetAdapter(List<NewsCommentBean.DataBean.CommentBean> list); /** * 加载完毕 */ void doShowNoMore(); } }

4.问答详情处理器
4.1.需要第三方库Jsoup的支持
在build.gradle中这样配置：
// 解析HTML implementation 'org.jsoup:jsoup:1.10.2'
4.2.源代码
public class WendaDetailPresenter implements IWendaDetail.Presenter { private IWendaDetail.View view; private String groupId; private int offset = 0; private List<NewsCommentBean.DataBean.CommentBean> commentsBeanList = new ArrayList<>(); WendaDetailPresenter(IWendaDetail.View view) { this.view = view; } @Override public void doRefresh() { if (commentsBeanList.size() != 0) { commentsBeanList.clear(); offset = 0; } view.onLoadData(); } @Override public void doLoadData(String url) { RetrofitFactory.getRetrofit().create(IMobileWendaApi.class) .getWendaAnsDetail(url) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .subscribe(new Consumer<ResponseBody>() { @Override public void accept(@NonNull ResponseBody responseBody) throws Exception { String result = getHTML(responseBody.string()); if (result != null) { view.onSetWebView(result, true); } else { view.onSetWebView(null, false); } view.onHideLoading(); } }, new Consumer<Throwable>() { @Override public void accept(@NonNull Throwable throwable) throws Exception { view.onSetWebView(null, false); view.onHideLoading(); ErrorAction.print(throwable); } }); } private String getHTML(String response) { Document doc = Jsoup.parse(response, "UTF-8"); Elements elements = doc.getElementsByClass("con-words"); String content = null; for (Element element : elements) { content = element.toString(); break; } if (content != null) { String css = "<link rel="stylesheet" href="file:///android_asset/toutiao_light.css" type="text/css">"; if (SettingUtil.getInstance().getIsNightMode()) { css = css.replace("toutiao_light", "toutiao_dark"); } String html = "<!DOCTYPE html> " + "<html lang="en"> " + "<head> " + " <meta charset="UTF-8">" + css + "<body> " + "<article class="article-container"> " + " <div class="article__content article-content">" + content + " </div> " + "</article> " + "</body> " + "</html>"; return html; } else { return null; } } @Override public void doLoadComment (String...ansId){ try { if (null == groupId) { this.groupId = ansId[0]; } } catch (ArrayIndexOutOfBoundsException e) { e.printStackTrace(); } RetrofitFactory.getRetrofit().create(IMobileNewsApi.class) .getNewsComment(groupId, offset) .subscribeOn(Schedulers.io()) .observeOn(AndroidSchedulers.mainThread()) .map(new Function<NewsCommentBean, List<NewsCommentBean.DataBean.CommentBean>>() { @Override public List<NewsCommentBean.DataBean.CommentBean> apply(@NonNull NewsCommentBean newsCommentBean) throws Exception { List<NewsCommentBean.DataBean.CommentBean> data = new ArrayList<>(); for (NewsCommentBean.DataBean bean : newsCommentBean.getData()) { data.add(bean.getComment()); } return data; } }) .compose(view.<List<NewsCommentBean.DataBean.CommentBean>>bindToLife()) .subscribe(new Consumer<List<NewsCommentBean.DataBean.CommentBean>>() { @Override public void accept(@NonNull List<NewsCommentBean.DataBean.CommentBean> list) throws Exception { if (list.size() > 0) { doSetAdapter(list); } else { doShowNoMore(); } } }, new Consumer<Throwable>() { @Override public void accept(@NonNull Throwable throwable) throws Exception { doShowNetError(); ErrorAction.print(throwable); } }); } @Override public void doLoadMoreComment () { offset += 10; doLoadComment(); } @Override public void doSetAdapter (List < NewsCommentBean.DataBean.CommentBean > list) { commentsBeanList.addAll(list); view.onSetAdapter(commentsBeanList); view.onHideLoading(); } @Override public void doShowNetError () { view.onHideLoading(); view.onShowNetError(); } @Override public void doShowNoMore () { view.onHideLoading(); if (commentsBeanList.size() > 0) { view.onShowNoMore(); } } }
4.3.构造函数，传入一个视图层。
4.4.重写刷新函数，调用视图层的加载。
4.5.重写加载数据，调用API。
4.6.获取HTML的一个函数。
传进去一个response的字符串。
利用Jsoup解析这个字符串，然后得到一个html。
方法源代码：
private String getHTML(String response) { Document doc = Jsoup.parse(response, "UTF-8"); Elements elements = doc.getElementsByClass("con-words"); String content = null; for (Element element : elements) { content = element.toString(); break; } if (content != null) { String css = "<link rel="stylesheet" href="file:///android_asset/toutiao_light.css" type="text/css">"; if (SettingUtil.getInstance().getIsNightMode()) { css = css.replace("toutiao_light", "toutiao_dark"); } String html = "<!DOCTYPE html> " + "<html lang="en"> " + "<head> " + " <meta charset="UTF-8">" + css + "<body> " + "<article class="article-container"> " + " <div class="article__content article-content">" + content + " </div> " + "</article> " + "</body> " + "</html>"; return html; } else { return null; } }
4.7.重写加载评论。
调用API，请求获取问答详情的评论。
4.8.重写加载更多评论。
4.9.重写设置适配器。
传进去一个List。
4.10.重写网络异常，没有更多了。
5.问答详情评论的视图绑定
5.1.这里用的依旧是新闻页面的视图绑定
在WendaDetailFragment中的一个initView中引用。
Register.registerNewsCommentItem(adapter);
在Register中注册数据类型。
/** * 新闻评论 * @param adapter */ public static void registerNewsCommentItem(@NonNull MultiTypeAdapter adapter) { adapter.register(NewsCommentBean.DataBean.CommentBean.class, new NewsCommentViewBinder()); adapter.register(LoadingBean.class, new LoadingViewBinder()); adapter.register(LoadingEndBean.class, new LoadingEndViewBinder()); }
5.2.回顾一下新闻评论的视图绑定
public class NewsCommentViewBinder extends ItemViewBinder<NewsCommentBean.DataBean.CommentBean,NewsCommentViewBinder.ViewHolder> { @NonNull @Override protected NewsCommentViewBinder.ViewHolder onCreateViewHolder(@NonNull LayoutInflater inflater, @NonNull ViewGroup parent) { View view = inflater.inflate(R.layout.item_news_comment, parent, false); return new ViewHolder(view); } @Override protected void onBindViewHolder(@NonNull final ViewHolder holder, @NonNull final NewsCommentBean.DataBean.CommentBean item) { final Context context = holder.itemView.getContext(); try { String iv_avatar = item.getUser_profile_image_url(); String tv_username = item.getUser_name(); String tv_text = item.getText(); int tv_likes = item.getDigg_count(); ImageLoader.loadCenterCrop(context, iv_avatar, holder.iv_avatar, R.color.viewBackground); holder.tv_username.setText(tv_username); holder.tv_text.setText(tv_text); holder.tv_likes.setText(tv_likes + "赞"); holder.itemView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { final String content = item.getText(); final BottomSheetDialogFixed dialog = new BottomSheetDialogFixed(context); dialog.setOwnerActivity((BaseActivity) context); View view = ((BaseActivity) context).getLayoutInflater().inflate(R.layout.item_comment_action_sheet, null); view.findViewById(R.id.layout_copy_text).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { ClipboardManager copy = (ClipboardManager) context.getSystemService(Context.CLIPBOARD_SERVICE); ClipData clipData = ClipData.newPlainText("text", content); copy.setPrimaryClip(clipData); Snackbar.make(holder.itemView, R.string.copied_to_clipboard, Snackbar.LENGTH_SHORT).show(); dialog.dismiss(); } }); view.findViewById(R.id.layout_share_text).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { IntentAction.send(context, content); dialog.dismiss(); } }); dialog.setContentView(view); dialog.show(); } }); } catch (Exception e) { ErrorAction.print(e); } } public class ViewHolder extends RecyclerView.ViewHolder { private ImageView iv_avatar; private TextView tv_username; private TextView tv_text; private TextView tv_likes; public ViewHolder(View itemView) { super(itemView); this.iv_avatar = itemView.findViewById(R.id.iv_avatar); this.tv_username = itemView.findViewById(R.id.tv_username); this.tv_text = itemView.findViewById(R.id.tv_text); this.tv_likes = itemView.findViewById(R.id.tv_likes); } } }
需要item布局==>item_news_comment.xml
<?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="@color/viewBackground"> <LinearLayout android:id="@+id/content" android:layout_width="match_parent" android:layout_height="wrap_content" android:background="?attr/selectableItemBackground" android:foreground="?attr/selectableItemBackground" android:orientation="vertical" android:paddingBottom="8dp" android:paddingLeft="16dp" android:paddingRight="16dp" android:paddingTop="8dp"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="horizontal"> <com.jasonjan.headnews.widget.CircleImageView android:id="@+id/iv_avatar" android:layout_width="22dp" android:layout_height="22dp" android:layout_gravity="center"/> <TextView android:id="@+id/tv_username" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_marginLeft="8dp" android:layout_marginStart="8dp" android:ellipsize="end" android:maxLines="1" tools:text="小恢恢的帽子"/> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="4dp" android:orientation="vertical"> <TextView android:id="@+id/tv_text" android:layout_width="wrap_content" android:layout_height="wrap_content" tools:text="光看个开头就笑的不行了，咱们中国有个传统，就是家里来客人了，要到门口迎一下，如果手里还带着礼物，那要先接过来，因为人家大老远一路带过来的，已经很累了，更何况老美不远万里带过来的呢，如果不接过来那也太不像话了，会让国际笑话中国，也有失大国风范！这也是一种礼貌，更是中华民族的传统美德！"/> <TextView android:id="@+id/tv_likes" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="2dp" android:gravity="end" android:maxLines="1" tools:text="4832赞"/> </LinearLayout> </LinearLayout> <View android:id="@+id/divider" android:layout_width="match_parent" android:layout_height="1px" android:layout_below="@+id/content" android:background="@color/line_divider"/> </RelativeLayout>
