Question

我遇到加载问题＆＃34; Glide＆＃34;图像进入＆＃34; ImageView＆＃34;使用＆＃34; viewPager＆＃34;。

当我尝试使用＆＃34; drawable＆＃34;资源它工作正常但由于某种原因（我猜因为它是异步）它不等待Glide更新视图。只有3个屏幕的空白viewPager没有崩溃。

另外，＆＃34; Firebase＆＃34;安装工作正常。

我知道很难用这么多的lib和东西复制一个问题，但是如果你能在评论部分提出一些建议那就太棒了

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;

import com.bumptech.glide.Glide;
import com.firebase.ui.storage.images.FirebaseImageLoader;
import com.google.firebase.storage.FirebaseStorage;
import com.google.firebase.storage.StorageReference;

public class ScreenSlidePageFragment extends Fragment {
    public static final String ARG_OBJECT = "object";

    // Firebase Initial code.
    private FirebaseStorage storage = FirebaseStorage.getInstance();
    private StorageReference storageRef = storage.getReferenceFromUrl("gs://myfirebase_example");
    private StorageReference fileRef = storageRef.child("images/3.jpg");

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    ViewGroup rootView = (ViewGroup) inflater.inflate(
            R.layout.fragment_screen_slide_page, container, false);

    Bundle args = getArguments();

    //TODO: Find out how to load the images with Glide, now it is not waiting.
    ImageView imageView = (ImageView) rootView.findViewById(R.id.imageView);
    //setImageResource(args.getInt(ARG_OBJECT));

    // Getting one image from the DB, it is working perfectly.
    Glide.with(getActivity())
            .using(new FirebaseImageLoader())
            .load(fileRef)
            .into(imageView);

    return rootView;
}
}

问题是缺少ImageView片段的默认图像。目前所有工作都按预期进行。

    <ImageView
    android:id="@+id/imageView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:srcCompat="@android:drawable/screen_background_dark" />

viewPager不显示Glide图像
