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
