Viewpager显示左右两侧

正常使用Viewpager的代码然后几处添加代码

主要是在这里还有布局中的属性

mViewpager.setPageMargin(30);//设置间距
mViewpager.setOffscreenPageLimit(mImagesList.size());

android:clipChildren="false"

适配器

public class Frag_Home_PagerAdapter extends PagerAdapter {
    private Context context;
    private List<String> mImageList;

    public Frag_Home_PagerAdapter(Context context, List<String> mImageList) {
        this.context = context;
        this.mImageList = mImageList;
    }

    @Override
    public int getCount() {
        return mImageList.size();
    }

    @Override
    public boolean isViewFromObject(@NonNull View view, @NonNull Object o) {
        return view == o;
    }

    @NonNull
    @Override
    public Object instantiateItem(@NonNull ViewGroup container, int position) {
        ImageView imageView = new ImageView(context);
        Glide.with(context).load(mImageList.get(position)).into(imageView);
        container.addView(imageView);
        return imageView;
    }

    @Override
    public void destroyItem(@NonNull ViewGroup container, int position, @NonNull Object object) {
        container.removeView((View) object);
    }
}

布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:clipChildren="false"
    android:id="@+id/frag_home_linner"
    android:layout_height="match_parent">

    <android.support.v4.view.ViewPager
        android:id="@+id/frag_home_viewpager"
        android:clipChildren="false"
        android:layout_width="match_parent"
        android:layout_marginLeft="@dimen/dp_30"
        android:layout_marginRight="@dimen/dp_30"
        android:layout_height="@dimen/dp_200"></android.support.v4.view.ViewPager>

</LinearLayout>

Activity层

mViewpager.setPageMargin(30);//设置间距
mViewpager.setOffscreenPageLimit(mImagesList.size());
Frag_Home_PagerAdapter homePagerAdapter = new Frag_Home_PagerAdapter(getActivity(),mImagesList);
mViewpager.setAdapter(homePagerAdapter);
