Question

Resim ile tek bir ızgara RecyclerView var, şimdi kullanıcı geri dönüştürücü View, RecyclerView resim göstergesini DetailActivity içinde tıklattığında istiyorum.

Bu

benim RecyclerAdapter geçerli:

public class AdapterRecyclerDars extends RecyclerView.Adapter<AdapterRecyclerDars.ViewHolder> { 
    private ArrayList<Modelars> arsha; 
    private Context context; 

    //========================================== constructor 

    public AdapterRecyclerDars(ArrayList<Modelars> arsha, Context context) { 
     this.arsha = arsha; 
     this.context = context; 
    } 

    //========================================== ViewHolder 
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{ 
     private TextView txt_grid; 
     private ImageView img_grid; 

     public ViewHolder(View itemView) { 
      super(itemView); 
      itemView.setOnClickListener(this); 
      txt_grid = (TextView)itemView.findViewById(R.id.txt_grid); 
      img_grid = (ImageView)itemView.findViewById(R.id.img_grid); 
     } 

     @Override 
     public void onClick(View v) { 

      Intent intent = new Intent(v.getContext(), DetailActivity.class); 
      intent.putExtra("img_id",img_grid.getId()); <== I don't know this 
      v.getContext().startActivity(intent); 
     } 
    } 
    //========================================== onCreateViewHolder 

    @Override 
    public AdapterRecyclerDars.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.grid_row, parent, false); 
     return new ViewHolder(view); 
    } 

    //========================================== onBindViewHolder 

    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 
     //setText 
     holder.txt_grid.setText(arsha.get(position).getars_name()); 
     //download image 
     Glide.with(context).load(arsha.get(position).getars_img()).into(holder.img_grid); 
    } 

    //========================================== getItemcount 

    @Override 
    public int getItemCount() { 
     return darsha.size(); 
    } 

    //========================================== 
    //========================================== 
} 

Ve Bu benim Fragment nerede RecyclerView Yükü:

public class Fragment_one extends Fragment { 
    ArrayList<Modelars> arsha; 

    @Nullable 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.fragment_one, container, false); 
     RecyclerView recyclerAvalDab = (RecyclerView) view.findViewById(R.id.recycler_frg_aval_dab); 
     // recyclerAvalDab.setHasFixedSize(true); 
     initializeData(); 
     RecyclerView.LayoutManager gridLayoutManager = new GridLayoutManager(getActivity(), 3); 
     recyclerAvalDab.setLayoutManager(gridLayoutManager); 



     AdapterRecyclerDars adapterRecyclerDars = new AdapterRecyclerDars(darsha, getActivity()); 
     recyclerAvalDab.setAdapter(adapterRecyclerDars); 
     return view; 
    } 

    private void initializeData() { 
     arsha = new ArrayList<>(); 
     arsha.add(new Modelars("1", R.drawable.z)); 
     arsha.add(new Modelars("2", R.drawable.s)); 
     arsha.add(new Modelars("3", R.drawable.r)); 
     arsha.add(new Modelars("4", R.drawable.f)); 
     arsha.add(new Modelars("5", R.drawable.a)); 
     arsha.add(new Modelars("6", R.drawable.ad)); 
     arsha.add(new Modelars("7", R.drawable.d)); 
     arsha.add(new Modelars("8", R.drawable.z)); 
    } 
} 

Answer 1

bu deneyin bence iş:

Sadece RecyclerAdapter yılında senin ViewHolder için bu satırı ekleyin:

public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{ 
     private TextView txt_grid; 
     private ImageView img_grid; 

     public ViewHolder(View itemView) { 
      super(itemView); 
      itemView.setOnClickListener(this); 
      txt_grid = (TextView)itemView.findViewById(R.id.txt_grid); 
      img_grid = (ImageView)itemView.findViewById(R.id.img_grid); 
     } 

     @Override 
     public void onClick(View v) { 

      Intent intent=new Intent(v.getContext(),DetailActivity.class); 
      Bundle bundle=new Bundle(); 
      bundle.putInt("IMAGE", arsha.get(getAdapterPosition()).getars_img()); 
      intent.putExtras(bundle); 
      v.getContext().startActivity(intent); 
     } 
    } 

Ve DetailActivity yılında Bu kodu onCreate yöntemiyle yazın:

int img_id; 

    if (bundle != null){ 
      img_id = bundle.getInt("IMAGE"); 
      imageview.setImageResource(img_id); 
     } 

öyle O: D

yerine Diğer Etkinlik için rehabilitasyon makinesi görünümünden Görüntü Gönderme Bir sonraki Etkinlikte resim elde etmek için img_grid.getId() kullanarak .

@Override 
    public void onBindViewHolder(ViewHolder holder, int position) { 
    ....your code here 
    //download image 
    int drawableID=arsha.get(position).getars_img(); 
    holder.img_grid.setTag(String.valueOf(drawableID)); 
    Glide.with(context).load(drawableID).into(holder.img_grid); 
    } 

Şimdi sonraki Etkinlik drawableID geçmesi: onBindViewHolder yöntemi olarak değişiklik gibi, her bir hücre ile depo resim verisi id img_grid ImageView e setTag yöntemi

intent.putExtra("drawableID",Integer.parseInt(img_grid.getTag().toString())); 

v.getContext() startActivity (niyet);

DetailActivity Bir Etkinlikte gösteri görüntü olarak:

int drawableID = bundle.getInt("drawableID")); 
imageView.setImageResource(drawableID);
