How to send a raster image to a bundle

Question

I am new to android. I want to transfer a bitmap to the bundle. But I cannot find any solution for this. Actually, I'm confused. I want to display an image in a fragment of a dialog. But I do not know how to put in the bundle. Should I send as PutByteArray() ? But if I pass the bitmap as an argument, it points out as an invalid argument.

Here is my code:

 public class MyAlert extends DialogFragment { Bitmap b; public MyAlert newInstance(Bitmap b) { this.b=b; MyAlert frag=new MyAlert(); Bundle args=new Bundle(); args.put("bitByte",b); frag.setArguments(args); return frag; } @Override public Dialog onCreateDialog(Bundle savedInstanceState) { Bitmap bitmap=getArguments().getByteArray("bitByte"); return new AlertDialog().Builder(getActivity()); AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()).setView(R.id.fragid).create(); 

Answer 1

First of all, convert it to a Byte array before adding it to the intent, send and decode.

// Convert to a byte array

  ByteArrayOutputStream stream = new ByteArrayOutputStream(); bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); byte[] byteArray = stream.toByteArray(); Bundle b = new Bundle(); b.putByteArray("image",byteArray); // your fragment code fragment.setArguments(b); 

get meaning through intention

 byte[] byteArray = getArgument().getByteArrayExtra("image"); Bitmap bmp = BitmapFactory.decodeByteArray(byteArray, 0, byteArray.length); 

Answer 2

No need to convert a bitmap to an array of bytes. You can directly place a raster image in a bundle. Refer to the following code to put the bitmap in the package.

 bundle.putParcelable("BitmapImage",bitmapname); 

Get the bitmap from the bundle using the following code

 Bitmap bitmapimage = getIntent().getExtras().getParcelable("BitmapImage");

I finally found it #pskink, and ShashiRajan said that we can transfer the bitmap directly. I implemented this way. MyAlert myAlert = new MyAlert(); Bundle b=new Bundle(); b.putParcelable("BitImage",bit); myAlert.setArguments(b); I hope this can be useful for some beginners like me, thanks for helping the guys.

If you want to transfer the image using the package, I'm sure that it will help you.

 Bundle bundle = new Bundle(); bundle.putParcelable("bitmap", bitmap); fragment.setArguments(bundle);

I think it’s easier to send the path or address of the image as a string and load it from the other side.

If the image is a web address, you can use the Glide or Picasso libraries and cache them, so it won’t load twice in other actions or fragments.
