购物车之订单列表

首先将购物车中确认订单的钱数传递到ConfirmActivity

接着购物车SecondActivity开始

package com.example.peng.goodscard_1510d.view;


import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.CheckBox;
import android.widget.ExpandableListView;
import android.widget.TextView;


import com.example.peng.goodscard_1510d.R;
import com.example.peng.goodscard_1510d.adapter.ElvAdapter;
import com.example.peng.goodscard_1510d.bean.GetCartBean;
import com.example.peng.goodscard_1510d.bean.PriceAndCount;
import com.example.peng.goodscard_1510d.presenter.GetCartPresenter;


import java.util.List;


public class SecondActivity extends AppCompatActivity implements ISecondListener {


    private GetCartPresenter getCartPresenter;
    private ExpandableListView mElv;
    /**
     * 全选
     */
    private CheckBox mCb;
    /**
     * 合计:
     */
    private TextView mTvTotal;
    /**
     * 去结算(0)
     */
    private TextView mTvCount;
    private ElvAdapter elvAdapter;
    private PriceAndCount priceAndCount;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_second);
        initView();
        getCartPresenter = new GetCartPresenter(this);
        getCartPresenter.getCart();


        mCb.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                elvAdapter.AllOrNone(mCb.isChecked());
            }
        });
    }


    @Override
    protected void onDestroy() {
        super.onDestroy();
        getCartPresenter.dettach();
    }


    @Override
    public void show(List<GetCartBean.DataBean> group, List<List<GetCartBean.DataBean.ListBean>> child) {
        elvAdapter = new ElvAdapter(this, group, child);
        mElv.setGroupIndicator(null);
        mElv.setAdapter(elvAdapter);
        for (int i = 0; i < group.size(); i++) {
            mElv.expandGroup(i);


        }
    }


    private void initView() {
        mElv = (ExpandableListView) findViewById(R.id.elv);
        mCb = (CheckBox) findViewById(R.id.cb);
        mTvTotal = (TextView) findViewById(R.id.tvTotal);
        mTvCount = (TextView) findViewById(R.id.tvCount);
        mTvCount.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //跳转到确认订单页面
                Intent intent = new Intent(SecondActivity.this, ConfirmActivity.class);
                if (priceAndCount != null) {
                    intent.putExtra("money", priceAndCount.getPrice() + "");
                }
                startActivity(intent);


            }
        });
    }


    public void setPriceAndCount(PriceAndCount priceAndCount) {
        this.priceAndCount = priceAndCount;
        mTvTotal.setText("合计：" + priceAndCount.getPrice());
        mTvCount.setText("去结算(" + priceAndCount.getCount() + ")");
    }


    public void setAllChecked(boolean bool) {
        mCb.setChecked(bool);
    }
}

---------------然后ConfirmActivity这个页面

package com.example.peng.goodscard_1510d.view;


import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;


import com.example.peng.goodscard_1510d.R;


public class ConfirmActivity extends AppCompatActivity implements View.OnClickListener {


    private TextView mTvLeft;
    /**
     * 立即下单
     */
    private Button mBt;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_confirm);
        //接收传过来实付款
        Intent intent = getIntent();
        String money = intent.getStringExtra("money");
        initView();
        mTvLeft.setText("实付款：¥" + money);
    }


    private void initView() {
        mTvLeft = (TextView) findViewById(R.id.tvLeft);
        mBt = (Button) findViewById(R.id.bt);
        mBt.setOnClickListener(this);
    }


    @Override
    public void onClick(View v) {
        switch (v.getId()) {
            default:
                break;
            case R.id.bt:
                //跳转到订单页面
                Intent intent = new Intent(ConfirmActivity.this, OrderActivity.class);
                startActivity(intent);
                break;
        }
    }
}

---------------activity_confirm布局文件

<?xml version="1.0" encoding="utf-8"?>
<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"
    tools:context="com.example.peng.goodscard_1510d.view.ConfirmActivity">


    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:background="#33000000">


        <TextView
            android:id="@+id/tvLeft"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" />


        <Button
            android:id="@+id/bt"

            android:layout_alignParentRight="true"
            android:background="#ff0000"
            android:text="立即下单" />
    </RelativeLayout>
</LinearLayout>

-----------------------------接着OrderActivity页面

package com.example.peng.goodscard_1510d.view;


import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.widget.LinearLayout;
import android.widget.TextView;


import com.example.peng.goodscard_1510d.R;
import com.example.peng.goodscard_1510d.fragment.AllFragment;
import com.example.peng.goodscard_1510d.fragment.WaitFragment;


import java.util.ArrayList;
import java.util.List;


public class OrderActivity extends AppCompatActivity {


    /**
     * 全部
     */
    private TextView mTvAll;
    /**
     * 待支付
     */
    private TextView mTvWait;
    private LinearLayout mLl;
    private ViewPager mVp;
    private List<Fragment> list = new ArrayList<>();


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_order);
        initView();
        list.add(new AllFragment());
        list.add(new WaitFragment());
        mVp.setAdapter(new MyAdapter(getSupportFragmentManager()));
    }


    private void initView() {
        mTvAll = (TextView) findViewById(R.id.tvAll);
        mTvWait = (TextView) findViewById(R.id.tvWait);
        mLl = (LinearLayout) findViewById(R.id.ll);
        mVp = (ViewPager) findViewById(R.id.vp);
    }


    class MyAdapter extends FragmentPagerAdapter {


        public MyAdapter(FragmentManager fm) {
            super(fm);
        }


        @Override
        public Fragment getItem(int position) {
            return list.get(position);
        }


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

-------------------------activity_order布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.example.peng.goodscard_1510d.view.OrderActivity">


    <LinearLayout
        android:id="@+id/ll"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">




        <TextView
            android:id="@+id/tvAll"
            android:layout_width="0dp"
            android:layout_height="40dp"

        android:id="@+id/vp"
        android:layout_width="match_parent"
        android:layout_height="match_parent"></android.support.v4.view.ViewPager>
</LinearLayout>

-----------all_fragment——订单列表中的ViewPage中的fragment，然后设置一个RecycleView

<?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="match_parent">


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

---------给RecycleView设置条目order_item

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">


    <TextView
        android:id="@+id/textView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="19dp"
        android:layout_marginStart="19dp"
        android:layout_marginTop="21dp"
        android:text="TextView" />


    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/textView"
        android:layout_alignParentEnd="true"
        android:layout_alignParentRight="true"
        android:layout_marginEnd="31dp"
        android:layout_marginRight="31dp"
        android:text="TextView" />


    <TextView
        android:id="@+id/textView3"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_alignStart="@+id/textView"
        android:layout_below="@+id/textView"
        android:layout_marginTop="27dp"
        android:text="TextView" />


    <TextView
        android:id="@+id/textView4"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignEnd="@+id/textView3"
        android:layout_alignRight="@+id/textView3"
        android:layout_below="@+id/textView3"
        android:layout_marginTop="24dp"
        android:text="TextView" />


    <TextView
        android:id="@+id/textView5"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        android:layout_alignEnd="@+id/textView2"
        android:layout_alignRight="@+id/textView2"
        android:text="TextView" />
</RelativeLayout>

------------------RecycleView的适配器RvAllAdapter

package com.example.peng.goodscard_1510d.adapter;


import android.content.Context;
import android.graphics.Color;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

        this.list = list;
    }


    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(context).inflate(R.layout.order_item, parent, false);
        return new MyViewHolder(view);
    }


    @Override

        OrderBean.DataBean dataBean = list.get(position);
        myViewHolder.tvTitle.setText(dataBean.getTitle());
        int status = dataBean.getStatus();
        myViewHolder.tvBt.setText("查看订单");
        myViewHolder.tvStatus.setTextColor(Color.parseColor("#000000"));

    }


    @Override

        private final TextView tvBt;


        public MyViewHolder(View itemView) {
            super(itemView);

            tvStatus = itemView.findViewById(R.id.textView2);
            tvPrice = itemView.findViewById(R.id.textView3);
            tvTime = itemView.findViewById(R.id.textView4);
            tvBt = itemView.findViewById(R.id.textView5);


        }
    }
}

-------------Fragment包~有两个类AllFragment,WaitFragment

AllFragment类（这里调用RvAllAdapter适配器）

package com.example.peng.goodscard_1510d.fragment;


import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;


import com.example.peng.goodscard_1510d.R;
import com.example.peng.goodscard_1510d.adapter.RvAllAdapter;
import com.example.peng.goodscard_1510d.bean.OrderBean;
import com.example.peng.goodscard_1510d.net.OkHttpUtils;
import com.google.gson.Gson;


import java.io.IOException;


import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.Response;


/**
 * Created by peng on 2017/12/20.
 */


public class AllFragment extends Fragment {


    private RecyclerView rv;


    @Override
    public void setUserVisibleHint(boolean isVisibleToUser) {
        super.setUserVisibleHint(isVisibleToUser);
    }




    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_all, null);
        rv = view.findViewById(R.id.rv);
        rv.setLayoutManager(new LinearLayoutManager(getActivity()));
        String url = "https://www.zhaoapi.cn/product/getOrders?uid=71";
        OkHttpUtils.getOkHttpUtils().doGet(url, new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {


            }


            @Override
            public void onResponse(Call call, Response response) throws IOException {
                String string = response.body().string();
                final OrderBean orderBean = new Gson().fromJson(string, OrderBean.class);
                getActivity().runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        RvAllAdapter adapter = new RvAllAdapter(getContext(), orderBean.getData());
                        rv.setAdapter(adapter);
                    }
                });
            }
        });
        return view;
    }
}

WaitFragment先空着
