先导入依赖

XML布局

<?xml version="1.0" encoding="utf-8"?><android.support.constraint.ConstraintLayout    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.nm.myapplication.MainActivity">    <com.youth.banner.Banner        android:layout_width="wrap_content"        android:layout_height="200dp"        android:id="@+id/ban"        ></com.youth.banner.Banner></android.support.constraint.ConstraintLayout>

写一个Banner类

package com.example.nm.myapplication;import android.content.Context;import android.provider.ContactsContract;import android.widget.ImageView;import com.bumptech.glide.Glide;import com.youth.banner.loader.ImageLoader;/** * Created by 爱新觉罗璎汉 on 2017/11/21. */public class Banner extends ImageLoader {    @Override    public void displayImage(Context context, Object path, ImageView imageView) {        com.nostra13.universalimageloader.core.ImageLoader imageLoader= com.nostra13.universalimageloader.core.ImageLoader.getInstance();        Glide.with(context).load(path).into(imageView);    }}
