Banner的使用

banner和VirePager一样,可以实现图片轮播的效果

创建工程,在包下的build.gradle下加入

compile 'com.youth.banner:banner:1.4.9'

主布局

<?xml version="1.0" encoding="utf-8"?><RelativeLayout    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.bannertext.MainActivity">    <com.youth.banner.Banner        android:layout_width="match_parent"        android:layout_height="300dp"        android:id="@+id/banner"        ></com.youth.banner.Banner></RelativeLayout>

bean类

Mimage

package com.example.bannertext;import android.content.Context;import android.widget.ImageView;import com.youth.banner.loader.ImageLoader;/** * Created by ass on 2017/10/23. */public class MImage extends ImageLoader {    @Override    public void displayImage(Context context, Object path, ImageView imageView) {        com.nostra13.universalimageloader.core.ImageLoader instance = com.nostra13.universalimageloader.core.ImageLoader.getInstance();        instance.displayImage((String) path, imageView);    }}

MyApplication

package com.example.bannertext;import android.app.Application;import com.nostra13.universalimageloader.core.ImageLoader;import com.nostra13.universalimageloader.core.ImageLoaderConfiguration;/** * Created by ass on 2017/10/23. */public class MyApplication extends Application {    @Override    public void onCreate() {        super.onCreate();        ImageLoaderConfiguration imageLoaderConfiguration=new ImageLoaderConfiguration.Builder(this).build();        ImageLoader.getInstance().init(imageLoaderConfiguration);    }}

MainActivity
