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

<?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_marginBottom="90dp" />

    </RelativeLayout>
</LinearLayout>
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

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。
