如何使用ViewPager显示Firebase中的图像

Question

我想显示存储在Firebase中的图像。我可以显示本地图像，但不确定如何从Firebase下载图像。

这是我的适配器类

public class ownPagerAdapter extends PagerAdapter {
private LayoutInflater layoutInflater;
private Context context;
private int[]  image = {R.drawable.pix2,R.drawable.pix1,R.drawable.pix4};


public ownPagerAdapter(Context context) {
    this.context = context;
}

@Override
public int getCount() {
    return image.length;
}

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

@NonNull
@Override
public Object instantiateItem(@NonNull ViewGroup container, int position) {
    layoutInflater=(LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View view=layoutInflater.inflate(R.layout.lay,null);
    ImageView imageView=(ImageView)view.findViewById(R.id.imageV);


    Glide.with(context).load(image[position]).into(imageView);


    ViewPager vp=(ViewPager)container;
    vp.addView(view,0);
    return view;
}

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

下面是我要显示图像的仪表板类

public class DashboardFragment extends Fragment {

View v;
ViewPager viewPager;
TabLayout tabLayout;

public DashboardFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
}

@Nullable
@Override
public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    v = inflater.inflate(R.layout.fragment_dashboard, container, false);

    viewPager = v.findViewById(R.id.viewPa);
    viewPager.setPadding(10, 0, 10, 0);

    ownPagerAdapter own = new ownPagerAdapter(getActivity());
    viewPager.setAdapter(own);
    tabLayout = v.findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(viewPager, true);

    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new MyTimer(), 5000, 6000);
    return v;
}

    class MyTimer extends TimerTask {

        @Override
        public void run() {
            if (getActivity() != null)
                getActivity().runOnUiThread(new Runnable() {

                    @Override
                    public void run() {

                        if (viewPager.getCurrentItem() == 0) {
                            viewPager.setCurrentItem(1);
                        } else if (viewPager.getCurrentItem() == 1) {
                            viewPager.setCurrentItem(2);
                        } else if (viewPager.getCurrentItem() == 2) {
                            viewPager.setCurrentItem(0);
                        }
                    }
                });
        }
    }
}

您能指导我如何从火力发电厂中挖掘图像，而不是从可绘制对象中加载图像吗？
