Assign The Intended Bitmap Value To An Imageview

I'm using an adapter to load the items to a grid. then when the user select an item from the grid then it opens up the customizing screen. In that process I'm sending some data in

Solution 1:

Instead of sending Bitmap with intent send drawable id.make following changes in getView method:

1. Get selected String from isVeg List:

@OverridepublicvoidonClick(View view) { 
        ...
        next.putExtra("isVeg", isVeg.get(position));  
        context.startActivity(next);
        ....
    }

2. Receive data in activity isVeg as String:

StringstrIsVag= getIntent().getStringExtra("isVeg"); 

3. Set Image to ImageView according to strIsVag :

    Bitmap mBitmap; 
    if (strIsVag.contains("true")) {
            mBitmap = BitmapFactory.decodeResource(
                                  this.getResources(), R.drawable.veg);
        } else {
            mBitmap = BitmapFactory.decodeResource(
                               this.getResources(), R.drawable.nonveg);
    }
   ImageView imageView = (ImageView) findViewById(R.id.grid_image);
   imageView.setImageBitmap(mBitmap);

Solution 2:

I would suggest to convert Bitmap object to string and send to your desired activity like this:-

next.putExtra("isVeg", BitMapToString(mBitmap));

These this function write below ViewHolder class like this

privateclassViewHolder{
private TextView tvHeader;
private ImageView ivImage;
private ImageView tvImageIcon;
}

publicString BitMapToString(Bitmap bitmap){
 ByteArrayOutputStream baos=new  ByteArrayOutputStream();
 bitmap.compress(Bitmap.CompressFormat.PNG,100, baos);
 byte [] b=baos.toByteArray();
 String temp=Base64.encodeToString(b, Base64.DEFAULT);
 return temp;
}

then in the receiving activity convert the string back to bitmap to use it to the imageview like this:-

StringmBitmapString= getIntent().getStringExtra("isVeg");
Bitmap mBitmap=StringToBitMap(mBitmapString);

Assign where you want

image.setImageBitmap(mBitmap);

public Bitmap StringToBitMap(String encodedString){
  try {
    byte [] encodeByte=Base64.decode(encodedString,Base64.DEFAULT);
    Bitmap bitmap=BitmapFactory.decodeByteArray(encodeByte, 0, encodeByte.length);
    return bitmap;
    } catch(Exception e) {
  e.getMessage();
  returnnull;
}

Solution 3:

After you download a image from url below is your code-

Picasso.with(this.context).load(imageUrls.get(position))
        .into(holder.ivImage);

final String strIsVag=isVeg.get(position);
final Bitmap mBitmap; 
if (strIsVag.contains("true")) {
        mBitmap = BitmapFactory.decodeResource(
                              this.context.getResources(), R.drawable.veg);
    } else {
        mBitmap = BitmapFactory.decodeResource(
                           this.context.getResources(), R.drawable.nonveg);
}

after that store that bitmap in local storage. and pass path of that storage dir by intent and display it in other activity a you want. below is code for store image in local storage-

   FileOutputStream out = new FileOutputStream(file);
   mBitmap .compress(Bitmap.CompressFormat.JPEG, 90, out);
   out.flush();
   out.close();

hope it will help you.

EDITED

create a file like -

Stringroot= Environment.getExternalStorageDirectory().toString();
FilemyDir=newFile(root + "/app_name");    
myDir.mkdirs();
Stringfname="image.jpg";
Filefile=newFile (myDir, fname);
if (file.exists ()) file.delete ();
