banner自动轮播的简单实现

当前app的build.gradle中添加compile 'com.youth.banner:banner:1.1.5'    红色字体为添加的代码 添加完成后重新编译

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.google.code.gson:gson:2.8.2'
    compile 'com.android.support:design:26.0.0-alpha1'
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.5'
    testCompile 'junit:junit:4.12'
    compile project(':PullToRefreshlibrary')
    compile 'com.youth.banner:banner:1.1.5'
}

//布局代码

//java代码
List list_path = new ArrayList<>();
        list_path.add(R.drawable.yx1);
        list_path.add(R.drawable.yx2);
        list_path.add(R.drawable.yx3);
        list_path.add(R.drawable.yx4);
        //设置圆形指示器与标题
        banner.setBannerStyle(Banner.CIRCLE_INDICATOR);
        //设置指示器位置（当banner模式中有指示器时）
        banner.setIndicatorGravity(Banner.CENTER);
        //设置自动轮播，默认为true
        banner.isAutoPlay(true);
        //设置轮播时间
        banner.setDelayTime(1500);
        //设置图片集合
        banner.setImages(list_path);
