Senden eines Bildes von einer RecyclerView zur nächstenActivity in eine ImageView mit Picasso

Question

Dies ist meine Adapterklasse, also in der onBindViewHolder Methode.
Ich bin auf der Suche nach einer Möglichkeit, das geladene Bild von Picasso an die NextActivity zu senden.

package adapters; 

import android.content.Context; 
import android.content.DialogInterface; 
import android.content.Intent; 
import android.support.v7.widget.RecyclerView; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.TextView; 
import android.widget.Toast; 

import com.squareup.picasso.Picasso;

import java.util.List;

import oerrride.we.huzykamz.ugentapp.ItemObjects; 
import oerrride.we.huzykamz.ugentapp.MovieScrollingActivity; 
import oerrride.we.huzykamz.ugentapp.NtindaCinemaViewHolders; 
import oerrride.we.huzykamz.ugentapp.R; 

/**

public class NtindaCinemaAdapter extends  RecyclerView.Adapter<NtindaCinemaViewHolders> { 
    private String url="http://10.0.2.2/UgandaEntertainment/Ntinda/NtindaPics/"; 
private List<ItemObjects> itemList = null; 
private Context context; 
public View root = null ; 


private ArrayList<ItemObjects> arraylist; 
public NtindaCinemaAdapter(Context context, List<ItemObjects> itemList) { 
    this.itemList = itemList; 
    this.context = context; 
} 

@Override 
public NtindaCinemaViewHolders onCreateViewHolder(ViewGroup parent, int viewType) { 

    View layoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.ntinda_cinema_list, parent,false); 
    NtindaCinemaViewHolders rcv = new NtindaCinemaViewHolders(layoutView,context); 
    return rcv; 
} 

@Override 
public void onBindViewHolder(NtindaCinemaViewHolders holder, final int position) { 
    final ItemObjects feedItem = itemList.get(position); 
     holder.root.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 


       Intent intent = new Intent(NtindaCinemaAdapter.this.context, MovieScrollingActivity.class); 
       intent.putExtra(NtindaCinemaViewHolders.KEY_SYNOPSIS, feedItem.getSynopsis()); 
       intent.putExtra(NtindaCinemaViewHolders.KEY_MOVIE_IMAGE, feedItem.getPhoto()+url); 

       context.startActivity(intent); 
      } 
     }); 



    //Download image using picasso library 

    Picasso.with(context).load(url+feedItem.getPhoto()) 
      .error(R.drawable.placeholder). 
      resize(500,500) 
      .placeholder(R.drawable.placeholder) 

      .into(holder.moviepic); 

    holder.moviename.setText(itemList.get(position).getMovieName()); 

} 

@Override 
public int getItemCount() { 
    return (null != itemList ? itemList.size() : 0); 
} 
} 

Das ist mein nextActivity, und wie ich es hier

       resize(500,500)

     FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab2); 
     fab.setOnClickListener(new View.OnClickListener() {

    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     // Handle action bar item clicks here. The action bar will 
     // automatically handle clicks on the Home/Up button, so long 
     // as you specify a parent activity in AndroidManifest.xml. 
     int id = item.getItemId(); 

     //noinspection SimplifiableIfStatement 
     if (id == R.id.action_settings) { 
      return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 
}

Es gibt paar Möglichkeiten, es zu tun, umgehen kann, aber in meinem Projekt, das ich auf diese Weise bin mit:

Zunächst Alle erhalten Bitmap von ImageView, konvertieren Sie es in base64String und übergeben Sie String über Intent.

Sie können es so erreichen:

Bitmap attachedbitmap= ((BitmapDrawable) imageview.getDrawable()).getBitmap(); 
Intent nextIntent=new Intent(this,SecondActivity.class); 
nextIntent.putExtra("image",encodeTobase64(attachedbitmap)); 

Ihre dekodieren und kodieren Methoden:

public static String encodeTobase64(Bitmap image) { 
    Bitmap immagex=image; 
    ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
    immagex.compress(Bitmap.CompressFormat.JPEG, 90, baos); 
    byte[] b = baos.toByteArray(); 
    String imageEncoded = Base64.encodeToString(b, Base64.DEFAULT); 
    // Log.e("LOOK", imageEncoded); 
    return imageEncoded; 
} 

public static Bitmap decodeBase64(String input) { 
    byte[] decodedByte = Base64.decode(input, 0); 
    return BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length); 
} 

In SecondActivity:

Bundle extras=getIntent().getExtras(); 
String imageString=extras.getString("image"); 
Bitmap incomingBitmap=decodeBase64(imageString);
