Я хочу получить изображения из базы данных Firebase и показать их в обзоре переработчика. Изображения уже загружены в базу данных и хранилище файловой базы. Но не могу понять, как получить изображения. До сих пор я пробовал описанный ниже метод, но могу получить только Textviews.
Activity. java
public class AssetListActivity extends AppCompatActivity {
private FloatingActionButton mAddAssetBtn;
private Toolbar mToolBar;
private DatabaseReference mAssetDatabase;
private RecyclerView mAssetRecyclerView;
private DatabaseReference mAssetIndDatabase;
String barcode;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_asset_list);
//Finding The Toolbar with it's unique Id.
mToolBar = (Toolbar) findViewById(R.id.main_page_toolbar);
mToolBar.setTitle("All Assets");
//Setting Up the ToolBar in The ActionBar.
setSupportActionBar(mToolBar);
barcode = getIntent().getStringExtra("barcode");
mAssetDatabase = FirebaseDatabase.getInstance().getReference().child("Assets");
mAssetDatabase.keepSynced(true);
mAssetRecyclerView = (RecyclerView) findViewById(R.id.assetRecyclerView);
mAssetRecyclerView.setHasFixedSize(true);
mAssetRecyclerView.setLayoutManager(new LinearLayoutManager(this));
mAddAssetBtn = (FloatingActionButton) findViewById(R.id.addAssetBtn);
mAddAssetBtn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(AssetListActivity.this , AddAssetActivity.class);
startActivity(intent);
}
});
}
@Override
protected void onStart() {
super.onStart();
Query query = mAssetDatabase.orderByChild("asset_name").limitToLast(50);
//Setting the up the FirebaseRecycerOption and passing the Model of the Data and the query of the Database.
FirebaseRecyclerOptions<AssetModel> options = new FirebaseRecyclerOptions.Builder<AssetModel>()
.setQuery(query, AssetModel.class).build();
FirebaseRecyclerAdapter<AssetModel , AssetViewHolder> recyclerAdapter = new FirebaseRecyclerAdapter<AssetModel , AssetViewHolder>(options) {
@Override
protected void onBindViewHolder(@NonNull AssetViewHolder assetViewHolder, int i, @NonNull AssetModel assetModel) {
assetViewHolder.setAssetName(assetModel.getAsset_name());
assetViewHolder.setAssetDescription(assetModel.getAsset_description());
assetViewHolder.setAssetLocation(assetModel.getAsset_location());
assetViewHolder.setAssetImage(assetModel.getAsset_image());
}
@NonNull
@Override
public AssetViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
//Setting up the LayoutInflater and passing on the SingleUserLayout.
View view = LayoutInflater.from(parent.getContext())
.inflate(R.layout.single_asset_layout, parent, false);
//Returning the UserViewHolder
return new AssetViewHolder(view);
}
};
mAssetRecyclerView.setAdapter(recyclerAdapter);
recyclerAdapter.startListening();
}
public static class AssetViewHolder extends RecyclerView.ViewHolder {
View mView;
public AssetViewHolder(@NonNull View itemView) {
super(itemView);
mView = itemView;
}
//Creating a new Method to set the Name in the RecyclerView.
public void setAssetName(String assetName) {
//Finding the TextView if the name with it's unique Id.
TextView mSingleAssetName = mView.findViewById(R.id.assetTitle);
mSingleAssetName.setText(assetName);
}
//Creating a new Method to set the Status in the RecyclerView.
public void setAssetDescription(String assetDescription) {
//Finding the TextView of the status with it's unique Id.
TextView mSingleAssetDescription = mView.findViewById(R.id.assetDescription);
mSingleAssetDescription.setText(assetDescription);
}
public void setAssetLocation(String assetLocation) {
//Finding the TextView of the status with it's unique Id.
TextView mSingleAssetLocation = mView.findViewById(R.id.assetLocation);
mSingleAssetLocation.setText(assetLocation);
}
//Creating a new Method to set the asset_image in the RecyclerView.
public void setAssetImage(String asset_image) {
ImageView mAssetImgView = mView.findViewById(R.id.assetImg);
Log.d("URL000025123" , asset_image);
Picasso.get().load(asset_image).placeholder(R.drawable.default_avatar_img).into(mAssetImgView);
}
}
}
Model. java
public class AssetModel {
private String asset_name;
private String asset_description;
private String asset_location;
private String asset_image;
public AssetModel() {
}
public AssetModel(String asset_name, String asset_description, String asset_location, String asset_image) {
this.asset_name = asset_name;
this.asset_description = asset_description;
this.asset_location = asset_location;
this.asset_image = asset_image;
}
public String getAsset_name() {
return asset_name;
}
public void setAsset_name(String asset_name) {
this.asset_name = asset_name;
}
public String getAsset_description() {
return asset_description;
}
public void setAsset_description(String asset_description) {
this.asset_description = asset_description;
}
public String getAsset_location() {
return asset_location;
}
public void setAsset_location(String asset_location) {
this.asset_location = asset_location;
}
public String getAsset_image() {
return asset_image;
}
public void setAsset_image(String asset_image) {
this.asset_image = asset_image;
}
}

Я могу получить другие данные, такие как имя и описание, но не могу понять узнайте, как получить изображения и как их отобразить в окне просмотра.
