我不知道我哪里出错了。请帮忙！ 我被包括在所有的库中，并且我用它来检索图像。 这是TestActivity.java
public class TestActivity extends AppCompatActivity {
private RecyclerView recyclerView;
private LinearLayoutManager linearLayoutManager;
private DatabaseReference databaseReference;
private FirebaseRecyclerAdapter<Post, PostViewHolder> mAdapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test);
databaseReference = FirebaseDatabase.getInstance().getReference().child("Posts");
recyclerView = (RecyclerView) findViewById(R.id.posts_list);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
}
@Override
public void onStart() {
super.onStart();
mAdapter = new FirebaseRecyclerAdapter<Post, PostViewHolder>(
Post.class,
R.layout.posts_row,
PostViewHolder.class,
databaseReference
)
{
@Override
protected void populateViewHolder(PostViewHolder viewHolder, Post model, int position) {
viewHolder.setDetails(model.getDetails());
viewHolder.setLocation(model.getLocation());
viewHolder.setImages(getApplicationContext(),model.getImages());
}
};
recyclerView.setAdapter(mAdapter);
}
public static class PostViewHolder extends RecyclerView.ViewHolder {
View view;
public PostViewHolder(View itemView) {
super(itemView);
view = itemView;
}
public void setLocation(String location) {
TextView textView = (TextView) view.findViewById(R.id.post_location);
textView.setText(location);
}
public void setDetails(String details) {
TextView textView = (TextView) view.findViewById(R.id.post_location);
textView.setText(details);
}
public void setImages(Context context, String images) {
ImageView image = (ImageView) view.findViewById(R.id.post_image);
Picasso.with(context).load(images).into(image);
}
}
}
这是Model Post类
public class Post {
public String Details, Location, Images;
public Post(String details, String location) {
Details = details;
Location = location;
}
public String getDetails() {
return Details;
}
public String getLocation() {
return Location;
}
public Post(){
}
public String getImages() {
return Images;
}
}
答案 0 :(得分：1)
您的代码中存在一些错误，使Firebase客户端感到困惑：
如果您将课程更改为惯用语，则看起来像
public class Post {
private String details, location, images;
public Post(){ }
public Post(String details, String location) {
this.details = details;
this.location = location;
}
public String getDetails() {
return details;
}
public String getLocation() {
return location;
}
public String getImages() {
return images;
}
}
或者，您可以拥有一个只包含公共字段（并且没有getter / setter）的类：
public class Post {
public String Details, Location, Images;
public Post(){ }
public Post(String details, String location) {
Details = details;
Location = location;
}
}

请尝试使用此模型类
@IgnoreExtraProperties
public class Post {
public String Details, Location, Images;
public Post(){
}
public Post(String details, String location, String images) {
Details = details;
Location = location;
Images = images;
}
@Exclude
public Map<String, Object> toMap() {
HashMap<String, Object> result = new HashMap<>();
result.put("Details", Details);
result.put("Location", Location);
result.put("Images", Images);
return result;
}
}
