淘忆项目之主页界面客户端的整理归纳

淘忆项目之主页界面客户端的整理归纳
主页主要包括两个部分，第一部分是轮播图，第二部分是全部物件的简略展示。
轮播图的实现。
首先是用photoshop设计界面：
 


先在build.gradle中添加
compile
'com.jude:rollviewpager:1.2.9'
然后重新加载一下内容。
第一步：建立一个新的Fragment。
首先添加一个类方法，命名为HomeRollShowAdapter，添加资源图片。
package
com.elainetaylor.blog.adapter;

import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;

import com.elainetaylor.blog.R;
import com.jude.rollviewpager.adapter.StaticPagerAdapter;
/**
 * Created by Eaine Taylor on 2016/7/15.
 */
public class HomeRollShowAdapter
extends StaticPagerAdapter {
    private int[]
imgs={R.mipmap.roll_huaibiao,R.mipmap.roll_qiche,R.mipmap.roll_shuben,R.mipmap.roll_xinagji};
    private Context
context;
    public HomeRollShowAdapter(Context context){
        this.context=context;
    }
    @Override
    public
View getView(ViewGroup container, int
position) {
        ImageView view=new
ImageView(container.getContext());
        view.setImageResource(imgs[position]);
        view.setScaleType(ImageView.ScaleType.CENTER_CROP);
        view.setLayoutParams(new
ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,
ViewGroup.LayoutParams.MATCH_PARENT));
        return view;
    }

    @Override
    public int
getCount() {
        return
imgs.length;
    }
}
第二步：首先，准备连接服务器的网址。
public static
String getHomeItemURL() {
    return
URL +
"/servlet/HomeItemAction";
}
第三步：根据图片编写布局文件：
<LinearLayout
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:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#f8f8f8"
    android:orientation="vertical"
    tools:context="com.elainetaylor.blog.ui.fragment.HomeFragment">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#fff">

        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            android:layout_margin="12dp"
            android:gravity="center"
            android:text="首页"
            android:textSize="20sp"
/>
    </LinearLayout>

    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:orientation="vertical">

                <com.jude.rollviewpager.RollPagerView
                    android:id="@+id/rp_home"
                    android:layout_width="match_parent"
                    android:layout_height="180dp"
                    android:layout_gravity="center">

                </com.jude.rollviewpager.RollPagerView>

                <View
                    android:layout_width="match_parent"
                    android:layout_height="4dp"
                    android:background="#f8f8f8"
/>
            </LinearLayout>

            <android.support.v7.widget.RecyclerView
                android:id="@+id/rv_home"
                android:layout_width="match_parent"
                android:layout_height="wrap_content">

            </android.support.v7.widget.RecyclerView>
        </LinearLayout>

    </ScrollView>

</LinearLayout>
第四步：编写item_home.xml文件的内容，作为recyclerView的每一个条目
<?xml version="1.0"
encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#fff"
    android:orientation="vertical">
    <View
        android:layout_width="match_parent"
        android:layout_height="8dp"
        android:background="#f8f8f8"/>
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        android:orientation="horizontal">

        <ImageView
            android:id="@+id/niv_Head"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginLeft="10dp"
            android:layout_marginStart="10dp"
            android:background="@drawable/ib_user_head"
            android:scaleType="fitXY"
/>

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginLeft="10dp"
            android:layout_marginStart="10dp"
            android:orientation="vertical">

            <TextView
                android:clickable="true"
                android:id="@+id/tv_Name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_gravity="start"
                android:layout_marginBottom="5dp"
                android:layout_marginTop="3dp"
                android:text="ElaineTaylor"
                android:textColor="#707070"
                android:textSize="13sp"
/>

            <TextView
                android:id="@+id/tv_Time"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="2016年07月11日"
                android:textColor="#4000"
                android:textSize="12sp"
/>
        </LinearLayout>

    </LinearLayout>

    <ImageView
        android:id="@+id/niv_ContentPic"
        android:layout_width="match_parent"
        android:layout_height="250dp"
        android:layout_marginTop="10dp"
        android:scaleType="fitXY"
/>

    <FrameLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dp"
        android:padding="3dp">

        <LinearLayout
            android:id="@+id/linearLayout2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="end"
            android:orientation="horizontal">

            <ImageView
                android:id="@+id/iv_save"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@mipmap/icon_star"
/>

            <TextView
                android:id="@+id/tv_SaveNum"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="0"
                android:layout_marginRight="2dp"
                android:layout_marginEnd="2dp"/>

            <ImageView
                android:id="@+id/iv_Mes"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:src="@mipmap/icon_message"
/>

            <TextView
                android:id="@+id/tv_MesNum"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="0"
                android:layout_marginRight="2dp"
                android:layout_marginEnd="2dp"/>
        </LinearLayout>

    </FrameLayout>

</LinearLayout>
第五步：然后是编写HomeItemAdapter的内容。
package
com.elainetaylor.blog.adapter;

import android.content.Context;
import android.content.Intent;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;

import com.elainetaylor.blog.R;
import com.elainetaylor.blog.listener.OnItemClickListener;
import com.elainetaylor.blog.ui.activity.HimActivity;
import com.nostra13.universalimageloader.core.ImageLoader;

import java.util.List;

/**
 * Created by Eaine Taylor on 2016/8/11.
 */
public class HomeItemAdapter
extends RecyclerView.Adapter<HomeItemAdapter.HomeItemViewHolder> {

    private
List<String> username;
    private List<String>
submitTime;
    private List<String>
headPic;
    private List<String>
contentPic;
    private List<Integer>
thingSaveNum;
    private List<Integer>
thingMesNum;
    private Context
context;
    private OnItemClickListener
listener;

    public HomeItemAdapter(List<String> username,
List<String> submitTime,
List<String> headPic,
List<String> contentPic,
List<Integer> thingSaveNum,
List<Integer> thingMesNum,
Context context) {
        this.username
= username;
        this.submitTime
= submitTime;
        this.headPic
= headPic;
        this.contentPic
= contentPic;
        this.thingSaveNum
= thingSaveNum;
        this.thingMesNum
= thingMesNum;
        this.context
= context;
    }

    public void
setOnItemClickListener(OnItemClickListener listener) {
        this.listener
= listener;
    }

    @Override
    public
HomeItemViewHolder onCreateViewHolder(ViewGroup parent, int
viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_home,
parent, false);
        HomeItemViewHolder holder =
new HomeItemViewHolder(view,
listener);
        return holder;
    }

    @Override
    public void
onBindViewHolder(HomeItemViewHolder holder, int
position) {
        holder.tvUsername.setText(username.get(position));
        holder.tvSubmitTime.setText(submitTime.get(position));
        holder.tvSaveNum.setText(thingSaveNum.get(position).toString());
        holder.tvMesNum.setText(thingMesNum.get(position).toString());
        ImageLoader loader=ImageLoader.getInstance();
        loader.displayImage(contentPic.get(position),holder.nivContentPic);
        loader.displayImage(headPic.get(position),holder.nivHeadPic);

    }

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

    class
HomeItemViewHolder extends
RecyclerView.ViewHolder implements
View.OnClickListener {
        public
TextView tvUsername,
tvSubmitTime,tvSaveNum,tvMesNum;
        public ImageView
nivHeadPic,
nivContentPic;
        public OnItemClickListener
listener;

        public HomeItemViewHolder(View itemView,
OnItemClickListener listener) {
            super(itemView);
            tvUsername
= (TextView) itemView.findViewById(R.id.tv_Name);
            tvSubmitTime
= (TextView) itemView.findViewById(R.id.tv_Time);
            tvSaveNum= (TextView) itemView.findViewById(R.id.tv_SaveNum);
            tvMesNum= (TextView) itemView.findViewById(R.id.tv_MesNum);
            nivHeadPic
= (ImageView) itemView.findViewById(R.id.niv_Head);
            nivContentPic
= (ImageView) itemView.findViewById(R.id.niv_ContentPic);
            this.listener
= listener;
            itemView.setOnClickListener(this);
            nivHeadPic.setOnClickListener(this);
            nivContentPic.setOnClickListener(this);
        }

        @Override
        public void
onClick(View view) {
            switch
(view.getId()){
                case
R.id.niv_Head://当用户点击头像的时候跳转到用户信息的界面
                    Intent intent=new
Intent(context,
HimActivity.class);
                    context.startActivity(intent);
                    break;
                case R.id.niv_ContentPic://当用户点击图片的时候跳转到详情页
                    if
(listener
!= null) {
                        listener.OnclickItemClick(view,
getPosition());
                    }
                    break;
            }

        }
    }
}
第六步：对HomeFragment的编写，这里的Fragment继承自BaseFragment，BaseFragment的内容和BaseActivity的内容差不多。
package
com.elainetaylor.blog.ui.fragment;

    }

    public void
getData() {
        StringRequest request =

                    JSONArray array = object1.getJSONArray("thing");
                    for (int

i--) {
                        JSONObject object = array.getJSONObject(i);
                        contentUrlList.add(UrlUtils.getPicUrl()

                        timeList.add(object.getString("submitTime"));
                        mesNumList.add(object.getInt("thingMesNum"));

                        nameList.add(object.getString("username"));
                        headUrlList.add(UrlUtils.getPicUrl()
+ object.getString("userHead"));
                    }
                    LinearLayoutManager manager =
new LinearLayoutManager(getActivity());
                    rvHome.setLayoutManager(manager);
                    adapter
= new
HomeItemAdapter(nameList,
timeList,
headUrlList,
contentUrlList,
saveNumList,
mesNumList,
getActivity());
                    rvHome.setAdapter(adapter);
                    adapter.setOnItemClickListener(HomeFragment.this);
                }
catch (JSONException e) {
                    e.printStackTrace();
                }
            }
        }, new
Response.ErrorListener() {
            @Override
            public void
onErrorResponse(VolleyError volleyError) {
                Toast.makeText(getActivity(),
"服务器出错",
Toast.LENGTH_SHORT).show();
            }
        });
        addRequestQueue(request);
    }
//将thingId传递给详情页
    @Override
    public void

        Intent intent = new

        startActivity(intent);
    }
}
