ConvenientBanner无线轮播 实现广告条

这是githud上地址  https://github.com/saiwu-bigkoo/Android-ConvenientBanner





如果只实现简单的效果   首先导入依赖

compile 'com.bigkoo:convenientbanner:1.1.4'


布局中引用
<com.bigkoo.convenientbanner.ConvenientBanner
    android:layout_width="match_parent"
    android:id="@+id/viewpager"
    android:layout_height="200dp">
</com.bigkoo.convenientbanner.ConvenientBanner>


主Activity代码
package com.example.longfei.viewpagerwuxian;

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;

import com.bigkoo.convenientbanner.CBViewHolderCreator;
import com.bigkoo.convenientbanner.ConvenientBanner;
import com.bigkoo.convenientbanner.OnItemClickListener;

import java.util.ArrayList;
import java.util.List;

public class MainActivity extends AppCompatActivity implements OnItemClickListener {

    private ConvenientBanner viewpager;

    private List<Integer> data = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        initView();
    }

    private void initView() {


        data.add(R.mipmap.a2);
        data.add(R.mipmap.a16);
        data.add(R.mipmap.a28);
        data.add(R.mipmap.a6);
        data.add(R.mipmap.a20);
        data.add(R.mipmap.a21);
        data.add(R.mipmap.a32);

        viewpager = (ConvenientBanner) findViewById(R.id.viewpager);
        viewpager.setPages(new CBViewHolderCreator() {
            @Override
            public Object createHolder() {

//我们需要实现一个Holder
                return new NetworkImageHolderView();      
      }      
  },data)
//设置我们现实的动画
.setPageTransformer(ConvenientBanner.Transformer.RotateDownTransformer)
.startTurning(2000).setPageIndicator(new int[]{R.drawable.select,R.drawable.def})
.setOnItemClickListener(this);    }   
 @Override    public void onItemClick(int position) {  
  }




//实现的holder

package com.example.longfei.viewpagerwuxian;

import android.content.Context;
import android.view.View;
import android.widget.ImageView;

import com.bigkoo.convenientbanner.CBPageAdapter;

/**
 * Created by longfei on 2016/10/14.
 */

public class NetworkImageHolderView implements CBPageAdapter.Holder<Integer> {

    ImageView imageView;

    @Override
    public View createView(Context context) {
        imageView = new ImageView(context);
        imageView.setScaleType(ImageView.ScaleType.FIT_XY);
        return imageView;
    }

    @Override
    public void UpdateUI(Context context, int position, Integer data) {

        imageView.setImageResource(data);

    }
}
 }




可以自定义两个小圆点

def


<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="rectangle" >
    <size android:width="5dp" android:height="5dp"/>
    <solid android:color="#ccc" />
    <corners android:radius="9dp" />
    <stroke android:width="1dp" android:color="#0f0"/>
</shape>


select

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="oval" >

    <solid android:color="#f00" />
    <stroke android:width="1dp" android:color="#0f0"/>

    <size android:width="5dp" android:height="5dp"/>
</shape>


这就可以了   记住如果是本地图片  holder里是integer类型   网络请求的是String
