VerticalBannerView是一个android平台下的自定义控件,通常用来展示广告,类似淘宝头条,它的样式如下:

1. 可自由定义展示的内容
2. 使用方式类似ListView/RecyclerView
3. 可为当前的内容添加各种事件,比如点击打开某个页面等

API >= 11

可以类比ListView

0. 添加依赖

   • Add it in your root build.gradle at the end of repositories:

     
         allprojects {
             repositories {
                 ...
                 maven { url "https://jitpack.io" }
             }
         }
     

   • Add the dependency

     dependencies {
     	        compile 'com.github.Rowandjj:VerticalBannerView:1.0'
     	}
     

1. 定义item的布局

   <?xml version="1.0" encoding="utf-8"?>
   <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                 android:orientation="vertical"
                 android:layout_width="match_parent"
                 android:background="#000"
                   android:gravity="center_vertical"
                 android:layout_height="60dp">
   
       <ImageView
           android:layout_marginLeft="10dp"
           android:id="@+id/iv"
           android:src="@android:drawable/ic_dialog_email"
           android:layout_width="30dp"
           android:layout_height="30dp"
           />
   
       <TextView
           android:id="@+id/tv_02"
           android:text="hello world"
           android:layout_marginLeft="10dp"
           android:textSize="16sp"
           android:layout_toRightOf="@id/iv"
           android:paddingLeft="5dp"
           android:textColor="#fff"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"/>
   
       <TextView
           android:layout_below="@id/tv_02"
           android:text="I am detail message......"
           android:layout_marginLeft="10dp"
           android:textSize="14sp"
           android:layout_centerVertical="true"
           android:layout_toRightOf="@id/iv"
           android:paddingLeft="5dp"
           android:textColor="#fff"
           android:layout_width="match_parent"
           android:layout_height="wrap_content"/>
   </RelativeLayout>
   

2. 实现adapter

   public class SampleAdapter01 extends BaseBannerAdapter<Model01> {
   
       private List<Model01> mDatas;
   
       public SampleAdapter01(List<Model01> datas) {
           super(datas);
       }
   
       @Override
       public View getView(VerticalBannerView parent) {
           return LayoutInflater.from(parent.getContext()).inflate(R.layout.item_01,null);
       }
   
       @Override
       public void setItem(final View view, final Model01 data) {
           TextView tv = (TextView) view.findViewById(R.id.tv_01);
           tv.setText(data.title);
           //你可以增加点击事件
           view.setOnClickListener(new View.OnClickListener() {
               @Override
               public void onClick(View v) {
                   //比如打开url
                   Toast.makeText(view.getContext(),data.url,Toast.LENGTH_SHORT).show();
               }
           });
       }
   }
   

3. 在布局中增加view的声明

      <com.taobao.library.VerticalBannerView
               android:id="@+id/banner_01"
               android:layout_width="match_parent"
               android:layout_height="40dp"
               app:animDuration="900" ---->动画间隔900ms
               app:gap="2000"/> ----->切换时长2000ms
   

4. 设置Adapter并启动

   List<Model01> datas02 = new ArrayList<>();
   datas02.add(new Model01("Life was so beautiful","--->Life was so beautiful,"));
   datas02.add(new Model01("From morning to evening","--->From morning to evening"));
   datas02.add(new Model01("We enjoyed the road to school","--->We enjoyed the road to school,"));
   datas02.add(new Model01("Birds chirped and Peace lingered","--->Birds chirped and Peace lingered"));
   final SampleAdapter02 adapter02 = new SampleAdapter02(datas02);
   final VerticalBannerView banner02 = (VerticalBannerView) findViewById(R.id.banner_02);
   banner02.setAdapter(adapter02);
   banner02.start();
   

5. 更新数据

   List<Model01> newData = new ArrayList<>();
   newData.add(new Model01("锄禾日当午","--->锄禾日当午"));
   newData.add(new Model01("汗滴禾下土","--->汗滴禾下土"));
   newData.add(new Model01("谁知盘中餐","--->谁知盘中餐"));
   newData.add(new Model01("粒粒皆辛苦","--->粒粒皆辛苦"));
   adapter02.setData(newData);
   
   

6. 停止

   banner02.stop();
