最近项目上需要实现这样效果的一个页面，本来想找个现成的两下搞定，但是问了半天度娘也没招，索性自己琢磨琢磨（这里边也少不了同事的帮助），先把最终的效果图贴上：

理论上讲，其本质并不复杂，就是一个viewpager，但是第一次实现这样的效果还是要花些时间的，具体的代码如下：

主布局文件：activity_show_industry_list.xml，主要就是一个activity上放个viewpager，但是相对布局是关键


<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="match_parent" android:layout_height="match_parent"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 android:orientation="vertical"
 android:background="@color/colorGrayBg">
 <huazheng.haiereng.views.TitleView
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  app:titleText="搜索框预留位置"
  app:showBackButton="true"
  android:id="@+id/titleView" />
 <RelativeLayout
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:clipChildren="false"
  android:layerType="software"
  android:id="@+id/awq_rl_vpc">
 <android.support.v4.view.ViewPager
  android:id="@+id/vp_show_industry_list"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:layout_gravity="center"
  android:clipChildren="false"
  android:layout_marginLeft="40dp"
  android:layout_marginRight="40dp"
  android:layout_marginBottom="90dp" />
 </RelativeLayout>
</LinearLayout>

fragment布局文件：fragment_show_industry_list.xml 该布局对应的类比较简单，就不往上贴了


<LinearLayout 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="huazheng.haiereng.BlankFragment"
 android:orientation="vertical"
 android:background="@color/colorWhite">
 <!-- TODO: Update blank fragment layout -->
 <FrameLayout
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="300dp" >
  <ImageView
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:id="@+id/iv_show_industry_list_pic"
   android:background="@mipmap/show_industry_detail"
   android:layout_gravity="center_horizontal" />
  <FrameLayout
   android:layout_width="match_parent"
   android:layout_height="35dp"
   android:layout_gravity="bottom"
   android:alpha="0.5"
   android:background="#333" />
  <FrameLayout
   android:layout_width="wrap_content"
   android:layout_height="35dp"
   android:layout_gravity="center_horizontal|bottom"
   android:id="@+id/frameLayout" >
   <LinearLayout
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <TextView
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:textAppearance="?android:attr/textAppearanceMedium"
     android:text="经济型酒店分体空调解决方案"
     android:textColor="@color/colorTextWhite"
     android:layout_gravity="center"
     android:id="@+id/tv_show_industry_list_title" />
   </LinearLayout>
  </FrameLayout>
 </FrameLayout>
 <TextView
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:textAppearance="?android:attr/textAppearanceMedium"
  android:text="广泛应用于住宅地产、宿舍、教学楼、通讯基站等，为其打造舒适空气解决方案"
  android:id="@+id/tv_show_industry_list_detail"
  android:layout_margin="20dp"
  android:textSize="@dimen/font_size_30"
  android:textColor="@color/colorTextGray" />
 <Button
  android:layout_width="120dp"
  android:layout_height="35dp"
  android:text="查看详情"
  android:id="@+id/bt_show_industry_list_cat"
  android:textColor="@color/colorTextWhite"
  android:layout_gravity="center_horizontal"
  android:background="@drawable/drawable_circle_corner" />
</LinearLayout>

主布局类ShowIndustryListActivity.java

  fragments.add(fragment4);
  viewPager.setOffscreenPageLimit(fragments.size());//卡片数量
  viewPager.setPageMargin(10);//两个卡片之间的距离，单位dp
  if (viewPager!=null){
   viewPager.removeAllViews();
  }
  MyFragmentPagerAdapter myFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager(), fragments);
  viewPager.setAdapter(myFragmentPagerAdapter);
 }

 public MyFragmentPagerAdapter(FragmentManager fm, ArrayList<Fragment> al) {
  super(fm);
  listFragments = al;
