Android实现横向滑动卡片效果
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
public class ShowIndustryListActivity extends BaseActivity { private FragmentPagerAdapter pagerada; private ShowIndustryListFragment showIndustryListFragment; ShowIndustryListFragment fragment1,fragment2,fragment3,fragment4; ArrayList<Fragment> fragments; @Bind(R.id.vp_show_industry_list) ViewPager viewPager; FragmentManager fragmentManager; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_show_industry_list); ButterKnife.bind(this); fragmentManager = getSupportFragmentManager(); fragments= new ArrayList<Fragment>(); fragment1 = new ShowIndustryListFragment(); fragment2 = new ShowIndustryListFragment(); fragment3 = new ShowIndustryListFragment(); fragment4 = new ShowIndustryListFragment(); fragments.add(fragment1); fragments.add(fragment2); fragments.add(fragment3); 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); } class MyFragmentPagerAdapter extends FragmentPagerAdapter { private ArrayList<Fragment> listFragments; public MyFragmentPagerAdapter(FragmentManager fm, ArrayList<Fragment> al) { super(fm); listFragments = al; } public MyFragmentPagerAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { return listFragments.get(position); } @Override public int getCount() { return listFragments.size(); } @Override public int getItemPosition(Object object) { return super.getItemPosition(object); } } }
至此,效果就可以实现了,上手试试吧。
