利用爬虫将电影网站打包成一个APP【二】

首先通过网络请求获取整个页面数据,然后正则匹配找到我们需要的数据,图片,链接,标题和评分,新建一个Bean类将数据储存到里面

public class DataBean {
private String DataName;
private String DataScore;
private String DataImg;
private String DataNetWork;

public String getDataName() {
      return DataName;
}

public void setDataName(String dataName) {
      DataName = dataName;
}

public String getDataScore() {
      return DataScore;
}

public void setDataScore(String dataScore) {
      DataScore = dataScore;
}

public String getDataImg() {
      return DataImg;
}

public void setDataImg(String dataImg) {
      DataImg = dataImg;
}

public String getDataNetWork() {
      return DataNetWork;
}

public void setDataNetWork(String dataNetWork) {
      DataNetWork = dataNetWork;
}
}

通过recyclerView将数据显示到界面上,通过接口回调设置点击事件点击图片跳转到详情页

RequestQueue queue = Volley.newRequestQueue(getActivity());
      MyStringRequest stringRequest = new MyStringRequest(getHosturl(), new Response.Listener<String>() {
         @Override
         public void onResponse(String response) {
            String regEx = "<li><div class=li-box><div class=img-box></div><a href=\"(.+?)\"><img src=\"(.+?)\" onerror=\".+?\"><span class=back></span><span>(.+?)</span></div><P><a href=\".+?\" target=\"_blank\">(.+?)</a></P></li>";

            Pattern pattern = Pattern.compile(regEx);
            mMatcher = pattern.matcher(response);
            if (mData != null) {
                  mData.clear();
            }
            new Thread(new Runnable() {
                  @Override
                  public void run() {
                     while (mMatcher.find()) {
                        //Log.e(TAG, matcher.group());
                        /*Log.e(TAG, mMatcher.group(1));
                        Log.e(TAG, mMatcher.group(2));
                        Log.e(TAG, mMatcher.group(3));
                        Log.e(TAG, mMatcher.group(4));*/
                        DataBean dataBean = new DataBean();
                        dataBean.setDataNetWork(mMatcher.group(1));
                        dataBean.setDataImg(mMatcher.group(2));
                        dataBean.setDataName(mMatcher.group(4));
                        dataBean.setDataScore(mMatcher.group(3));
                        mData.add(dataBean);
                     }
                  }
            }).start();
            if (mHomeAdapter == null) {
                  mHomeAdapter = new homeAdapter(getContext(), mData, mGridLayoutManager);
            }
            mRecyclerView.setAdapter(mHomeAdapter);
            mHomeAdapter.notifyDataSetChanged();
            mTvThisPage.setText("第"+mThisPage+"页");
            Toast.makeText(getContext(), "第" + mThisPage + "页", Toast.LENGTH_SHORT).show();
            mHomeAdapter.setItemClickListener(new homeAdapter.OnItemClickListener() {
                  @Override
                  public void onItemClick(int position) {
                     String url = mData.get(position).getDataNetWork();
                     String title = mData.get(position).getDataName();
                     String img_url = mData.get(position).getDataImg();
                     String requestUrl = getHosturl() + url;
                     //Toast.makeText(getContext(), requestUrl, Toast.LENGTH_SHORT).show();
                     Intent intent = new Intent(getContext(), DetailsActivity.class);
                     intent.putExtra("title", title);
                     intent.putExtra("img_url", img_url);
                     intent.putExtra("requestUrl", requestUrl);
                     startActivity(intent);
                  }
            });

            //Log.e(TAG, response);

         }
      }, new Response.ErrorListener() {
         @Override
         public void onErrorResponse(VolleyError error) {
            Log.e(TAG, error.getMessage(), error);
            mThisPage--;
            Toast.makeText(getContext(), "网络不稳定!加载失败!请稍后重试!", Toast.LENGTH_SHORT).show();

         }
      });
      queue.add(stringRequest);
}

为了便于维护将首页封装成基类,然后将电影,电视剧和动漫页面继承,稍加改动,这样4个页面就出来了

public class MoveFragment extends HomeFragment implements View.OnClickListener {

@Override
protected void intitView() {
      hostUrl = "http://m.yiybb.com/dianying/";
      super.intitView();
      mThisPage = 1;
      listTpye = "List_15_";
      mTvThisPage.setVisibility(View.VISIBLE);

}

@Override
protected void initData() {
      super.initData();
}

@Override
protected String setTitle() {
      return "电影";
}

@Override
protected void setViibilly() {
      page.setVisibility(View.VISIBLE);
}
