如何在 recyclerview viewHolder 中使用 picasso？

Question

我正在尝试在我的项目中使用 Picasso 而不是 R.drawable，我正在尝试更改代码，但我发现很难将 Picasso 与我的 Viewholder 一起使用，也许你们可以帮助我并告诉我如何更改我的代码以使用 Picasso。

java.class

public class RibeiraDePena_PT extends AppCompatActivity
{
DrawerLayout drawerLayout;
Toolbar toolbar;
NavigationView navigationView;
RecyclerView recyclerView;
RecyclerView.Adapter programAdapter;
RecyclerView.LayoutManager layoutmanager;
//Indicar Titulo, descricao e imagem(mesmo tamanho)
String[] programTituloList =
        {
                "Ponte Romana / do Trajano","Praça de Camões"
        };
String[] programDescList =
        {
                "Descricao-Ponte",
                "Descricao-praça camoes     hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh"


        };
int [] programImages =
        {
                R.drawable.chaves_estelas,R.drawable.chaves_estelas
        };
String[] Url =
        {
                "https://www.google.com","https://www.google.com"
        };

@Override
protected void onCreate(Bundle savedInstanceState)
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.ribeira_tr);
    recyclerView = findViewById(R.id.recyclerview);
    layoutmanager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(layoutmanager);
    programAdapter = new ProgramAdapter(this, programTituloList, programDescList, programImages, Url);
    recyclerView.setAdapter(programAdapter);

    NavigationView navigationView = (NavigationView) findViewById(R.id.navigationview);
    navigationView.setItemIconTintList(null);
    drawerLayout = findViewById(R.id.drawerlayout);
    setSupportActionBar(toolbar);
    navigationView = findViewById(R.id.navigationview);
    toolbar = findViewById(R.id.toolbar);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar,
            R.string.navigration_open, R.string.navigration_close);
    drawerLayout.addDrawerListener(toggle);
    toggle.syncState();
}

adpater.class

public class ProgramAdapter extends RecyclerView.Adapter<ProgramAdapter.ViewHolder> {
Context context;
String[] programTituloList;
String[] programDescList;
String[] Url;
int[] programImages;

public static class ViewHolder extends RecyclerView.ViewHolder {
    TextView rowTitulo;
    TextView rowDesc;
    ImageView rowImage;

    public ViewHolder(@NonNull View itemView) {
        super(itemView);
        rowTitulo = itemView.findViewById(R.id.txt_titulo);
        rowDesc = itemView.findViewById(R.id.txt_desc);
        rowImage = itemView.findViewById(R.id.imagem_box);

    }
}

public ProgramAdapter(Context context, String[] programTituloList,
                      String[] programDescList, int[] images, String[] Url) {
    this.context = context;
    this.programTituloList = programTituloList;
    this.programDescList = programDescList;
    this.programImages = images;
    this.Url = Url;

}
@NonNull
@Override
public ProgramAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {

    LayoutInflater inflater = LayoutInflater.from(context);
    View view = inflater.inflate(R.layout.box, parent, false);
    ViewHolder viewHolder = new ViewHolder(view);
    return viewHolder;

}

@Override
public int getItemCount() {
    return programTituloList.length;
}

@Override
public void onBindViewHolder(@NonNull ProgramAdapter.ViewHolder holder, int position) {
    holder.rowTitulo.setText(programTituloList[position]);
    holder.rowDesc.setText(programDescList[position]);
    holder.rowImage.setImageResource(programImages[position]);

    holder.rowImage.setOnClickListener(new View.OnClickListener()
    {

        @Override
        public void onClick(View view)
        {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(Uri.parse(Url[holder.getBindingAdapterPosition()]));
            context.startActivity(intent);
        }
    });
}

我成功地在 Viewholder 之外使用了 Picasso。

Answer 1

将 onBindViewHolder 中的 holder.rowImage.setImageResource(programImages[position]); 替换为

Picasso.get().load(programImages[position]).into(holder.rowImage);
