AutoPlayViewPager

仿京东、淘宝，横向自动轮播图。Auto Play ViewPager。

效果

Gradle

//使用 autoplay viewpager
compile ('com.xyzlf.autoplay.viewpager:viewpager:0.0.5') {
    exclude group: 'com.android.support', module: 'appcompat-v7'
}

使用方式

1、在xml中使用，如下：

<!-- 使用默认颜色，大小，间距 -->
<com.xyzlf.autoplay.viewpager.CustomerBanner
    android:id="@+id/banner"
    android:layout_width="match_parent"
    android:layout_height="150dp"/>

<!--自定义颜色，大小，间距-->
<com.xyzlf.autoplay.viewpager.CustomerBanner
    android:id="@+id/banner"
    android:layout_width="match_parent"
    android:layout_height="150dp"
    custom:indicator_radius="3dp"
    custom:indicator_span="16dp"
    custom:indicator_selected_color="#ff0000"
    custom:indicator_unselected_color="#00ff00"
    custom:indicator_bottommargin="20dp"/>

2、代码中使用：

List<Integer> list = new ArrayList<>();
list.add(R.drawable.pic_1);
list.add(R.drawable.pic_2);
list.add(R.drawable.pic_3);
list.add(R.drawable.pic_4);
    
CustomerBanner banner = (CustomerBanner) findViewById(R.id.banner);
banner.setAdapter(new AutoPlayPagerAdapter(list));

3、Adapter需要继承 AutoPagerAdapter，完整Adapter代码如下：

public class AutoPlayPagerAdapter extends AutoPagerAdapter {

    private List<Integer> list;

    public AutoPlayPagerAdapter(List<Integer> list) {
        this.list = list;
    }

    @Override
    public View getView(LayoutInflater layoutInflater, int position) {
        ImageView imageView = new ImageView(getApplicationContext());
        ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
        imageView.setLayoutParams(params);
        int resId = list.get(getPositionForIndicator(position));
        imageView.setImageDrawable(ContextCompat.getDrawable(MainActivity.this, resId));
        return imageView;
    }

    @Override
    public int getDataCount() {
        return list == null ? 0 : list.size();
    }
}

可以下载Demo看看，代码是最好的老师。
