首先，上成功之后的效果图

接下来从gradle导入

compile 'com.jcodecraeer:xrecyclerview:1.3.2'

然后上布局


<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    xmlns:app="http://schemas.android.com/apk/res-auto"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.zhangshuyang01.coupondemo.MainActivity"    android:orientation="vertical">    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="优惠券Demo"        app:layout_constraintBottom_toBottomOf="parent"        app:layout_constraintLeft_toLeftOf="parent"        app:layout_constraintRight_toRightOf="parent"        app:layout_constraintTop_toTopOf="parent"/>    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical"        >        <RelativeLayout            android:id="@+id/rl_empty"            android:layout_width="match_parent"            android:layout_height="match_parent"            >            <ImageView                android:layout_width="match_parent"                android:layout_height="wrap_content"                android:layout_marginLeft="10dp"                android:layout_marginRight="10dp"                android:src="@mipmap/wallet_no_coupon" />            <TextView                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_centerHorizontal="true"                android:layout_marginTop="130dp"                android:visibility="gone"                android:text="邀请好友进行分享" />        </RelativeLayout>        <RelativeLayout            android:layout_width="match_parent"            android:layout_height="match_parent"            android:layout_marginTop="-10dp"            android:background="#f5f5f5">            <com.jcodecraeer.xrecyclerview.XRecyclerView                android:id="@+id/xrv_list"                android:layout_width="fill_parent"                android:layout_height="fill_parent"                android:scrollbarSize="0.5dp"                android:scrollbars="vertical" />        </RelativeLayout>    </LinearLayout></LinearLayout>

adapter中item的布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"              android:id="@+id/ll_item"              android:layout_width="match_parent"              android:layout_height="wrap_content"              android:layout_marginTop="6dp"              android:orientation="vertical">    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="110dp"        android:layout_marginLeft="10dp"        android:layout_marginRight="10dp"        android:background="@mipmap/user_wallet_coupon">        <LinearLayout            android:id="@+id/rl_time"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:orientation="horizontal"            android:layout_centerVertical="true"            android:layout_marginLeft="35dp">            <TextView                android:id="@+id/tv_use_time1"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="2"                android:includeFontPadding="false"                android:textColor="#333333"                android:textSize="35sp"/>            <TextView                android:layout_alignParentBottom="true"                android:id="@+id/tv_unit"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:includeFontPadding="false"                android:layout_marginLeft="10dp"                android:layout_toRightOf="@id/tv_use_time1"                android:text="小时"                android:textColor="#333333"                android:textSize="13sp"/>        </LinearLayout>        <View            android:id="@+id/line"            android:layout_width="0.5dp"            android:layout_height="match_parent"            android:layout_marginBottom="18dp"            android:layout_marginLeft="18dp"            android:layout_marginTop="18dp"            android:layout_toRightOf="@id/rl_time"            android:background="#dcdcdc"/>        <RelativeLayout            android:id="@+id/rl_text"            android:layout_width="wrap_content"            android:layout_height="60dp"            android:layout_centerVertical="true"            android:layout_marginLeft="18dp"            android:layout_toRightOf="@+id/line">            <TextView                android:id="@+id/tv_coupon_name"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:text="用车券"                android:textColor="#333333"                android:textSize="24sp"/>            <RelativeLayout                android:id="@+id/rl_bottom"                android:layout_width="wrap_content"                android:layout_height="wrap_content"                android:layout_alignParentBottom="true">                <TextView                    android:id="@+id/tv_coupon_time"                    android:layout_width="wrap_content"                    android:layout_height="wrap_content"                    android:layout_centerVertical="true"                    android:text="有效期至2017-01-10"                    android:textColor="#666666"                    android:textSize="13sp"/>            </RelativeLayout>        </RelativeLayout>    </RelativeLayout></LinearLayout>

主程序中的代码

public class MainActivity extends AppCompatActivity {    private XRecyclerView xRecyclerView;    private RelativeLayout rl_empty;    private int page=1,total_page,isOnRefresh=1;    private ArrayList<Map<String,String>> mapList ;    private MyCouponAdapter mAdapter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        xRecyclerView = (XRecyclerView) findViewById(R.id.xrv_list);        rl_empty = (RelativeLayout) findViewById(R.id.rl_empty);        init();        LinearLayoutManager layoutManager = new LinearLayoutManager(this);        layoutManager.setOrientation(LinearLayoutManager.VERTICAL);        xRecyclerView.setLayoutManager(layoutManager);        xRecyclerView.setRefreshProgressStyle(ProgressStyle.BallSpinFadeLoader);        xRecyclerView.setLoadingMoreProgressStyle(ProgressStyle.Pacman);        xRecyclerView.setEmptyView(rl_empty);        xRecyclerView.setLoadingMoreEnabled(true);        xRecyclerView.setLoadingListener(new XRecyclerView.LoadingListener() {            @Override            public void onRefresh() {                page=1;                isOnRefresh=2;            }            @Override            public void onLoadMore() {                if (total_page-page>0){                    page++;                }else {                    xRecyclerView.loadMoreComplete();                }            }        });        mAdapter = new MyCouponAdapter(mapList);        xRecyclerView.setAdapter(mAdapter);    }    public void init() {        mapList = new ArrayList<>();        for (int i = 1; i < 10; i++) {            Map<String, String> maps = new HashMap<>();            maps.put("number", ""+i);            maps.put("unit", ""+i);            maps.put("description", "描述"+i);            maps.put("failtrue_time", "2018/"+i);            mapList.add(maps);        }    }}
