1.导入依赖

'com.youth.banner:banner:1.4.9'

2.添加权限

<uses-permission android:name="android.permission.INTERNET" />//联网
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />//读取外置存储卡

3.添加布局

<com.youth.banner.Banner
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/banner"
    android:layout_width="match_parent"
    android:layout_height="150dp" />

4.在Activity 中编写代码，相关代码含义已经全部添加注释

public class MyBanner extends AppCompatActivity implements OnBannerListener {
    private Banner banner;
    private ArrayList<String> list_path;
    private ArrayList<String> list_title;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
