安卓實現橫向滑動的卡片效果

最近專案上需要實現這樣效果的一個頁面,本來想找個現成的兩下搞定,但是問了半天度娘也沒招,索性自己琢磨琢磨(這裡邊也少不了同事的幫助),先把最終的效果圖貼上:
理論上講,其本質並不複雜,就是一個viewpager,但是第一次實現這樣的效果還是要花些時間的,具體的程式碼如下:
主佈局檔案:activity_show_industry_list.xml,主要就是一個activity上放個viewpager,但是相對佈局是關鍵
fragment佈局檔案:fragment_show_industry_list.xml 該佈局對應的類比較簡單,就不往上貼了<?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="搜尋框預留位置" 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>
<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="經濟型酒店分體空調解決方案" 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="廣泛應用於住宅地產、宿舍、教學樓、通訊基站等,為其打造舒適空氣解決方案" 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="檢視詳情" android:id="@+id/bt_show_industry_list_cat" android:textColor="@color/colorTextWhite" android:layout_gravity="center_horizontal" android:background="@drawable/drawable_circle_corner" /> </LinearLayout>
主佈局類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());//卡片數量 viewPager.setPageMargin(10);//兩個卡片之間的距離,單位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,效果就可以實現了,上手試試吧。
