使用说明：

activity 的布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
    <com.mingle.pulltonextlayout.PullToNextLayout
        android:id="@+id/pullToNextLayout"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"/>
</RelativeLayout>

简单说明 :  布局中只有一个控件PullToNextLayout, 控件中不包含其他组件

java 代码中引用使用:

 pullToNextLayout= (PullToNextLayout) findViewById(R.id.pullToNextLayout);
        list=new ArrayList<Fragment>();
        list.add(new ScrollViewFragment(0));
        list.add(new ScrollViewFragment(1));
        list.add(new ScrollViewFragment(2));
        list.add(new ScrollViewFragment(3));
        list.add(new ScrollViewFragment(4));
        list.add(new ScrollViewFragment(5));
        list.add(new ScrollViewFragment(6));
        list.add(new ScrollViewFragment(7));
//设置适配器
        pullToNextLayout.setAdapter(new PullToNextAdapter(getSupportFragmentManager(), list));
       pullToNextLayout.setOnItemSelectListener(new OnItemSelectListener() {
            @Override
            public void onSelectItem(int position, View view) {
                setTitle(position+1+".0 谷歌仍是毕业生心目中的最佳雇主");
            }
        });
        setTitle(1+".0 谷歌仍是毕业生心目中的最佳雇主");

主要方法:setAdapter(PullToNextAdapter pullToNextAdapter) 主要设置数据源适配器.setAdapter(PullToNextAdapter pullToNextAdapter,int  currentIndex) 设置数据源适配器.并且指定第一个显示的位置.setOnItemSelectListener(OnItemSelectListener onItemSelectListener) 设置选中回调.
