一個(gè)頁(yè)面顯示多個(gè)ViewPager的Item，如何在一個(gè)頁(yè)面上顯示ViewPager的多個(gè)item焦蘑？

一共有兩種解決方案：
第一種就是我們上文所說的clipChildren屬性盯拱，
第二種是clipToPadding屬性

只需要在父容器和ViewPager中都添加上clipChildren屬性，然后給ViewPager設(shè)置左右兩個(gè)margin例嘱，使其不致于把整個(gè)屏幕占滿狡逢，就是這么簡(jiǎn)單

<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"  
    android:clipChildren="false"  
    tools:context="org.lenve.myviewpagercards.MainActivity">  
  
    <android.support.v4.view.ViewPager  
        android:id="@+id/viewpager"  
        android:layout_width="match_parent"  
        android:layout_height="200dp"  
        android:layout_marginLeft="60dp"  
        android:layout_marginRight="60dp"  
        android:clipChildren="false"></android.support.v4.view.ViewPager>  
</RelativeLayout>  

我們?cè)賮砜纯碫iewPager的Adapter：

public class MyVpAdater extends PagerAdapter {  
    private List<Integer> list;  
    private Context context;  
  
    public MyVpAdater(Context context, List<Integer> list) {  
        this.context = context;  
        this.list = list;  
    }  
  
    @Override  
    public int getCount() {  
        return list.size();  
    }  
  
    @Override  
    public boolean isViewFromObject(View view, Object object) {  
        return view == object;  
    }  
  
    @Override  
    public Object instantiateItem(ViewGroup container, int position) {  
        ImageView iv = new ImageView(context);  
        iv.setImageResource(list.get(position));  
        container.addView(iv);  
        return iv;  
    }  
  
    @Override  
    public void destroyItem(ViewGroup container, int position, Object object) {  
        container.removeView((View) object);  
    }  
} 

ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);  
viewPager.setPageMargin(80);  
viewPager.setOffscreenPageLimit(3);
MyVpAdater adater = new MyVpAdater(this, list);  
viewPager.setAdapter(adater);  

比我們一般使用ViewPager多了兩行代碼，
一個(gè)是setOffscreenPageLimit拼卵，這個(gè)是設(shè)置預(yù)加載的頁(yè)數(shù)奢浑，我們知道默認(rèn)情況下這個(gè)參數(shù)為1，也就是左右各預(yù)加載一頁(yè)腋腮，但是我們這里要讓左右各預(yù)加載兩頁(yè);
另外一個(gè)PageMargin就好說了雀彼，就是設(shè)置ViewPager中兩頁(yè)之間的距離。OK即寡，那我們來看看顯示效果：

第二種：(ViewPager結(jié)合CardView)
那就是clipToPadding徊哑，這個(gè)屬性是什么意思呢？它表示是否允許ViewGroup在ViewGroup的padding中進(jìn)行繪制嘿悬，默認(rèn)情況下該屬性的值為true实柠，即不允許在ViewGroup的padding中進(jìn)行繪制。

<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="org.lenve.myviewpagercards2.MainActivity">  
  
    <android.support.v4.view.ViewPager  
        android:id="@+id/viewpager"  
        android:layout_width="match_parent"  
        android:layout_height="200dp"  
        android:clipToPadding="false"  
        android:paddingBottom="24dp"  
        android:paddingLeft="48dp"  
        android:paddingRight="48dp"  
        android:paddingTop="24dp"></android.support.v4.view.ViewPager>  
</RelativeLayout>  

ViewPager的Adapter如下：

public class MyAdapter extends PagerAdapter {  
    private List<Integer> list;  
    private Context context;  
    private LayoutInflater inflater;  
  
    public MyAdapter(Context context, List<Integer> list) {  
        this.context = context;  
        this.list = list;  
        inflater = LayoutInflater.from(context);  
    }  
    @Override  
    public int getCount() {  
        return list.size();  
    }  
  
    @Override  
    public boolean isViewFromObject(View view, Object object) {  
        return view == object;  
    }  
  
    @Override  
    public Object instantiateItem(ViewGroup container, int position) {  
        View view = inflater.inflate(R.layout.vp_item, container, false);  
        container.addView(view);  
        return view;  
    }  
  
    @Override  
    public void destroyItem(ViewGroup container, int position, Object object) {  
        container.removeView((View) object);  
    }  
}  

調(diào)用

ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);  
        List<Integer> list = new ArrayList<>();  
        MyAdapter adapter = new MyAdapter(this, list);  
        viewPager.setAdapter(adapter);  
        viewPager.setPageMargin((int) TypedValue.applyDimension(
            TypedValue.COMPLEX_UNIT_DIP,  48, getResources().getDisplayMetrics()));  
        viewPager.setPageTransformer(false, new ScaleTransformer(this));
