应用程序不检索图像从firebase实时数据库在android工作室与Java

Question

请我想检索图像与文本从Firebase实时数据库到一个RecyclerView使用CardView其中包含ImageView的图像和两个TextView的价格和标题，我已经能够检索文本，但图像不显示我使用滑动，只有错误持有人图像显示，我已经实现了依赖关系和注释处理器以及但仍然，图像不显示。我还需要做些什么吗?

请把我的代码放在RecyclerAdapter

RecyclerArrayAdapter extends RecyclerView.Adapter<RecyclerArrayAdapter.ViewHolder> {
Context context;
ArrayList<Data> ImagesArrayList;
public RecyclerArrayAdapter(Context context) {
this.context = context;
}
public RecyclerArrayAdapter(Context context, ArrayList<Data> imagesArrayList) {
this.context = context;
ImagesArrayList = imagesArrayList;
}
@NonNull
@Override
public RecyclerArrayAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.image,parent, false);
return new RecyclerArrayAdapter.ViewHolder(view);
}
@Override
public void onBindViewHolder(@NonNull RecyclerArrayAdapter.ViewHolder holder, int position) {

Glide.with(context)
.asBitmap()
.override(120,120)
. placeholder 
(R.drawable.common_image)
.dontAnimate()
.error(R.drawable.common_second_image)            
.load(ImagesArrayList.get(position).getImage())
.into(holder.mImage);
holder.mTitle.setText(ImagesArrayList.get(position).getTitle());
holder.mPrice.setText(String.valueOf(ImagesArrayList.get(position).getPrice()));
}
@Override
public int getItemCount() {     

return ImagesArrayList.size();
}
public class ViewHolder extends RecyclerView.ViewHolder {
CircleImageView mImage;
TextView mTitle;
TextView mPrice;
public ViewHolder(@NonNull View itemView) {
super(itemView);
mImage = (CircleImageView) itemView.findViewById(R.id.image_locate);
mTitle = (TextView) itemView.findViewById(R.id.title);
mPrice =(TextView) itemView.findViewById(R.id.price_tag);
}

下面是MainActivity.java

中的代码

Public class Ladies_Dresses_Page extends AppCompatActivity{
private RecyclerArrayAdapter private recyclerArrayAdapter;
private RecyclerView recyclerView;
private ArrayList<Data> modelArrayList;
DatabaseRefrence  = database;
recyclerView = findViewById(R.id.dressRecycler);
database=FirebaseDatabase.getInstance().getReference("Data");
database.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot snapshot) {
clearAll();
for (DataSnapshot snapshot1 : snapshot.getChildren()){
Data data = new Data();
data.setTitle(snapshot1.child("title").getValue().toString());
data.setImage(snapshot1.child("image").getValue().toString());
data.setPrice(Integer.parseInt(snapshot1.child("price").getValue().toString()));
modelArrayList.add(data);
}
recyclerArrayAdapter = new RecyclerArrayAdapter(getApplicationContext(),modelArrayList);
recyclerView.setAdapter(recyclerArrayAdapter);

}
@Override
public void onCancelled(@NonNull DatabaseError error) {

Toast.makeText(Ladies_Dresses_Page.this, "ERROR"+ error.getMessage(),Toast.LENGTH_SHORT).show()
}
private void clearAll() {
if (modelArrayList != null) {
modelArrayList.clear();
if (recyclerArrayAdapter != null) {
recyclerArrayAdapter.notifyDataSetChanged();
}
}
modelArrayList = new ArrayList<>();
}

下面是我的Model类 中的代码

public class Data {
String title, image;
int price;
public Data(){};
public Data(String title, String image, int price) {
this.title = title;
this.image = image;
this.price = price;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getImage() {
return image;
}
public void setImage(String image) {
this.image = image;
}
public int getPrice() {
return price;
public void setPrice(int price) {
this.price = price;
}

请查看我的数据库

Answer 1

问题不在于代码，而在于数据库。一个URL，看起来像这样:

gs://顶点- shop.appspot.com/img - 20210119 - wa0029.jpg

这不是一个可以被Glide使用的有效URL。要解决这个问题，您必须更改Data节点中的所有子节点，以保存有效的url，这些url以https://...开头，并直接指向所需的图像。
