module 链接：http://pan.baidu.com/s/1qXD2UPe 密码：lz0t

1.在build.gradle(Module app)中添加包,并import module

dependencies {    compile project(':convenientbanner')}

2.新建java类NetworkImageHolderView

import android.content.Context;import android.view.View;import android.widget.ImageView;import com.bigkoo.convenientbanner.holder.Holder;import com.nostra13.universalimageloader.core.ImageLoader;import xiaoye.com.supersavingstyrant.R;/** * Created by 小烨 on 2017/7/10. */public class NetworkImageHolderView implements Holder<String> {    private ImageView imageView;    @Override    public View createView(Context context) {        //你可以通过layout文件来创建，也可以像我一样用代码创建，不一定是Image，任何控件都可以进行翻页        imageView = new ImageView(context);        imageView.setScaleType(ImageView.ScaleType.FIT_XY);        return imageView;    }    @Override    public void UpdateUI(Context context,int position, String data) {        imageView.setImageResource(R.drawable.ic_default_adimage);        ImageLoader.getInstance().displayImage(data,imageView);    }}

3.布局文件中添加

<com.bigkoo.convenientbanner.ConvenientBanner        android:id="@+id/convenientBanner"        android:layout_width="match_parent"        android:layout_height="match_parent"        app:canLoop="true"/>

4.Activity中添加

public class GoodsDetail extends AppCompatActivity implements AdapterView.OnItemClickListener, ViewPager.OnPageChangeListener, OnItemClickListener {    private ConvenientBanner convenientBanner;    protected ImageLoader imageLoader;    private List<String> networkImages=new ArrayList<String>();     protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        netinit();    }    private void netinit() {        campusShopbean=(CampusShopBean)getIntent().getSerializableExtra("campusgoods");        convenientBanner = (ConvenientBanner) findViewById(R.id.convenientBanner);        imageLoader = ImageLoader.getInstance();        imageLoader.init(ImageLoaderConfiguration.createDefault(this));        for(int i=0;i<campusShopbean.getImgs().size();i++){            networkImages.add(Url.picUrl+campusShopbean.getImgs().get(i).getImg());        }        convenientBanner.setPages(new CBViewHolderCreator<NetworkImageHolderView>() {            @Override            public NetworkImageHolderView createHolder() {                return new NetworkImageHolderView();            }        },networkImages)                //设置指示器是否可见                .setPointViewVisible(true)                //设置自动切换（同时设置了切换时间间隔）                .startTurning(2000)                //设置两个点图片作为翻页指示器，不设置则没有指示器，可以根据自己需求自行配合自己的指示器,不需要圆点指示器可用不设                .setPageIndicator(new int[]{R.drawable.ic_page_indicator, R.drawable.ic_page_indicator_focused})                //设置指示器的方向（左、中、右）                .setPageIndicatorAlign(ConvenientBanner.PageIndicatorAlign.ALIGN_PARENT_RIGHT)                //设置点击监听事件                .setOnItemClickListener(this)                //设置手动影响（设置了该项无法手动切换）                .setManualPageable(true);    }    @Override    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {    }    @Override    public void onPageSelected(int position) {        //Toast.makeText(context,"监听到翻到第"+position+"了",Toast.LENGTH_SHORT).show();    }    @Override    public void onPageScrollStateChanged(int state) {    }    @Override    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {        String transforemerName = DefaultTransformer.class.getSimpleName();        try {            Class cls = Class.forName("com.ToxicBakery.viewpager.transforms." + transforemerName);            ABaseTransformer transforemer= (ABaseTransformer)cls.newInstance();            convenientBanner.getViewPager().setPageTransformer(true,transforemer);            //部分3D特效需要调整滑动速度            if(transforemerName.equals("StackTransformer")){                convenientBanner.setScrollDuration(1200);            }        } catch (ClassNotFoundException e) {            e.printStackTrace();        } catch (java.lang.InstantiationException e) {            e.printStackTrace();        } catch (IllegalAccessException e) {            e.printStackTrace();        }    }    @Override    public void onItemClick(int position) {        //Toast.makeText(context,"点击了第"+position+"个",Toast.LENGTH_SHORT).show();    }}
