高仿知乎日報(四)[主頁面條目顯示]

這篇繼續解決上一篇遺留下來的問題：

很簡單，讓ContentActivity的recylerView響應點擊事件便可。先來看看我的代碼結構吧，方便查看對應是哪個類。請看下圖：

ViewPager的點擊事件響應，本來一開始打算用setOnPageChangeListener來實現，但發現這個回調已經在實現輪詢播放的時候占用了並且每次滑動都會調用，所以不應該在這裡做處理。那麼只能在viewPager的adapter裡面加載頁面的時候做響應。RecylerClickListener是一個接口，用來響應條目的點擊事件，在ContentActivity實現這個接口。下面是HomeViewPagerAdapter:

package com.example.seaice.zhihuribao.adapter;

import android.support.v4.view.PagerAdapter;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import com.example.seaice.zhihuribao.R;
import com.example.seaice.zhihuribao.RecylerClickListener;
import com.example.seaice.zhihuribao.Utils.BaseApplication;
import com.example.seaice.zhihuribao.bean.HomeTopInfo;
import com.squareup.picasso.Picasso;
import java.util.List;
import butterknife.ButterKnife;

/**
 * viewPager的adapter
 * Created by seaice on 2016/8/18.
 */
public class HomeViewPagerAdapter extends PagerAdapter {
   private List homeTopInfoList;
   private RecylerClickListener mListener;

   public HomeViewPagerAdapter(List imageViewList) {
       this.homeTopInfoList = imageViewList;
   }

   //設置item listener
   public void setOnItemClickListener(RecylerClickListener listener) {
       this.mListener = listener;
   }

   @Override
   public Object instantiateItem(ViewGroup viewGroup, final int position) {
       LayoutInflater layoutInflater = LayoutInflater.from(BaseApplication.getApplication());
       View RootView = layoutInflater.inflate(R.layout.top_view_pager, viewGroup, false);
       //響應viewPager的點擊事件
       RootView.setOnClickListener(new View.OnClickListener() {
           @Override
           public void onClick(View v) {
               if (mListener != null) {
                   mListener.onPagerClick(null, position);
               }
           }
       });
       ButterKnife.inject(RootView);
       TextView topTitle = ButterKnife.findById(RootView, R.id.top_title);
       ImageView topImage = ButterKnife.findById(RootView, R.id.top_image);
       topTitle.setText(homeTopInfoList.get(position).getTitle());
                 Picasso.with(BaseApplication.getApplication()).load(homeTopInfoList.get(position).getImage()).fit().into(topImage);
       viewGroup.addView(RootView);
       return RootView;
   }

   @Override
   public int getCount() {
       return homeTopInfoList.size();
   }

   @Override
   public boolean isViewFromObject(View view, Object object) {
       return view == object;
   }

   @Override
   public void destroyItem(ViewGroup viewGroup, int position, Object object) {
       viewGroup.removeView((View) object);
   }
}

RecylerView對應條目的點擊事件，同樣也是調用RecylerClickListener這個接口來實現：

package com.example.seaice.zhihuribao;
import android.view.View;

public interface RecylerClickListener {
    void onItemClck(View view, int position);//用於recyleview的普通item
    void onPagerClick(View view, int position);//用於viewPager來實現
}

在HomeRecylerViewAdapter的MyViewHolder裡面實現點擊，調用這個接口。之前在MyViewHolder裡面的控件設置setOnClickListener都沒有效果，至今還沒弄清楚為啥？最後發現必須是設置Holder.itemView的click監聽才能實現點擊回調，這個需要注意一下，請看代碼：

//顯示日報條目的Holder
public class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    public ImageView iv_title;
    public TextView tv_title;
    private RecylerClickListener listener;

    public MyViewHolder(View view, RecylerClickListener listener) {
        super(view);
        iv_title = ButterKnife.findById(view, R.id.iv_title);
        tv_title = ButterKnife.findById(view, R.id.tv_title);
        this.listener = listener;
        this.itemView.setOnClickListener(this);//必須是itemView才能設置
    }

    @Override
    public void onClick(View v) {
        LogUtils.e("myviewholder onclick");
        if (listener != null) {
            listener.onItemClck(v, getPosition() - 1);
        }
    }
}

ContentActivity實現RecylerClickListener接口，RecylerView的條目點擊後進入到日報的詳情頁面NewsInfoActivity：

    //recyler條目點擊的回調
    @Override
    public void onItemClck(View view, int position) {
        HomeStoriesInfo info = homeInfo.getHomeStoriesInfos().get(position);
        Toast.makeText(this, info.getTitle(), Toast.LENGTH_SHORT).show();
        String id = info.getId();
        Intent intent = new Intent();
        intent.putExtra("id", id);
        intent.setClass(this, NewsInfoActivity.class);
        startActivity(intent);
    }

    //viewpager點擊的回調
    @Override
    public void onPagerClick(View view, int position) {
        HomeTopInfo info = homeInfo.getHomeTopInfoList().get(position);
        String id = info.getId();
        Intent intent = new Intent();
        intent.putExtra("id", id);
        intent.setClass(this, NewsInfoActivity.class);
        startActivity(intent);
    }

NewsInfoActivity就是顯示日報具體某條新聞的頁面，組成就是一條頂端的bar+webView。直接看布局文件：

NewsInfoActivity實際上不用做什麼操作,直接加載布局文件就搭建出頁面來了，當然部分功能未實現，先把大概寫出來吧。

}

    LogUtils.e(id);

CommentActivity是顯示評論的界面，這裡順手也寫出來，同樣是頂端bar+RecylerView來實現。原版知乎日報的UI效果目前我還做不出來，只能先把大體顯示出來。布局文件activity_comment：

        }
    }

@Override

實際上來講，實現評論列表顯示的，還得靠RecylerView的Adapter,CommentRecylerViewAdapter:

不過還是敬請期待吧！！
