Day five

一、段子数据的获取

段子数据的获取其实跟妹子模块的方法基本一样

先编写实体类

public class DuanziBean {

    @SerializedName("group")
    private GroupBean groupBean;
    private String type;

    public GroupBean getGroupBean() {
        return groupBean;
    }

    public void setGroupBean(GroupBean groupBean) {
        this.groupBean = groupBean;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }
    
}

public class GroupBean {

    private String text;
    private long id;
    private UserBean user;

    public String getText() {
        return text;
    }

    public long getId() {
        return id;
    }

    public UserBean getUser() {
        return user;
    }

    public static class UserBean {

        private long user_id;
        private String name;
        private String avatar_url;

        public String getName() {
            return name;
        }

        public String getAvatar_url() {
            return avatar_url;
        }

    }
}

写好实体类之后，使用我们之前已经封装好的网络请求工具以及解析工具，便能将返回的数据，解析成一个包含段子实体类的 List。

二、段子的显示

老规矩，先写个 RecyclerView 的 Item

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:orientation="vertical"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:paddingLeft="8dp"
        >

        <de.hdodenhof.circleimageview.CircleImageView
            android:id="@+id/duanzi_civ_avatar"
            android:layout_width="24dp"
            android:layout_height="24dp"
            android:src="@drawable/avatar"
            android:layout_gravity="center"
            />

        <TextView
            android:id="@+id/duanzi_tv_author"
            android:paddingLeft="8dp"
            android:paddingStart="8dp"
            android:layout_width="match_parent"
            android:layout_height="16dp"
            android:text="DeveloperHaoz"
            android:layout_gravity="center_vertical"
            />

    </LinearLayout>

    <TextView
        android:id="@+id/duanzi_tv_content"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="10dp"
        android:paddingLeft="40dp"
        android:paddingRight="10dp"
        android:text=""
        />
    <include layout="@layout/layout_app_divide"/>

</LinearLayout>

然后编写将数据和界面进行绑定的 Adapter

public class DuanziAdapter extends RecyclerView.Adapter<DuanziAdapter.DuanziViewHolder>{

    private Fragment mFragment;
    private List<DuanziBean> mDuanziBeanList;

    public DuanziAdapter(Fragment fragment, List<DuanziBean> duanziBeanList){
        this.mFragment = fragment;
        this.mDuanziBeanList = duanziBeanList;
    }

    @Override
    public DuanziViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_duanzi, null);
        return new DuanziViewHolder(view);
    }

    @Override
    public void onBindViewHolder(DuanziViewHolder holder, int position) {
        try {
            DuanziBean duanziBean = mDuanziBeanList.get(position);
            Glide.with(mFragment).load(duanziBean.getGroupBean().getUser().getAvatar_url()).into(holder.mCivAvatar);
            holder.mTvContent.setText(duanziBean.getGroupBean().getText());
            holder.mTvAuthor.setText(duanziBean.getGroupBean().getUser().getName());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    @Override
    public int getItemCount() {
        return mDuanziBeanList.size();
    }

    public static class DuanziViewHolder extends RecyclerView.ViewHolder{

        private CircleImageView mCivAvatar;
        private TextView mTvAuthor;
        private TextView mTvContent;

        public DuanziViewHolder(View itemView) {
            super(itemView);
            mCivAvatar = (CircleImageView) itemView.findViewById(R.id.duanzi_civ_avatar);
            mTvAuthor = (TextView) itemView.findViewById(R.id.duanzi_tv_author);
            mTvContent = (TextView) itemView.findViewById(R.id.duanzi_tv_content);
        }
    }


}

最后段子页面中进行数据和获取以及界面的初始化

public class DuanziFragment extends Fragment {

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_duanzi, container, false);
        ButterKnife.bind(this, view);
        initView();
        initRefresh();
        return view;
    }

    private void initRefresh() {
        mRefresh.setColorSchemeResources(R.color.colorPrimary);
        mRefresh.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                initView();
                mRefresh.setRefreshing(false);
            }
        });
    }

    private void initView() {
        VolleyHelper.sendHttpGet(getActivity(), DuanziApi.GET_DUANZI, new VolleyResponseCallback() {
            @Override
            public void onSuccess(String response) {
                List<DuanziBean> mDuanziBeanList = GsonHelper.getDuanziBeanList(response);
                mDuanziBeanList.remove(3);
                mRvShowDuanzi.setLayoutManager(new LinearLayoutManager(getActivity()));
                mRvShowDuanzi.setAdapter(new DuanziAdapter(DuanziFragment.this, mDuanziBeanList));
            }

            @Override
            public void onError(VolleyError error) {
                Logger.d(error);
            }
        });
    }

}
