Add this to method in public class in your activity MainActivity.java

   private void shareImageAndText(Bitmap bitmap){  
     Uri uri = getImageToShare(bitmap);  
     Intent intent = new Intent(Intent.ACTION_SEND);  
     intent.putExtra(Intent.EXTRA_STREAM,uri);  
     intent.putExtra(Intent.EXTRA_TEXT,"Sharing Images");  
     intent.putExtra(Intent.EXTRA_SUBJECT,"Subject");  
     intent.setType("image/png");  
     startActivity(Intent.createChooser(intent,"Share via"));  
   }  
   
   private Uri getImageToShare (Bitmap bitmap){  
     File imageFolder = new File(getCacheDir(),"images");  
     Uri uri = null;  
   
     try {  
       imageFolder.mkdir();  
       File file = new File(imageFolder,"shared_image.png");  
       FileOutputStream outputStream = new FileOutputStream(file);  
       bitmap.compress(Bitmap.CompressFormat.PNG,90,outputStream);  
       outputStream.flush();  
       outputStream.close();  
       uri = FileProvider.getUriForFile(MainActivity.this,"com.bdtopcoder.imagesharing", file);  
     } catch (Exception e){  
       Toast.makeText(this, "Exception: "+e.getMessage(), Toast.LENGTH_SHORT).show();  
     }  
     return uri;  
   }  

Button setOnClickListener code:

     button.setOnClickListener(view -> {  
       BitmapDrawable bitmapDrawable = (BitmapDrawable) imageView.getDrawable();  
       Bitmap bitmap = bitmapDrawable.getBitmap();  
       shareImageAndText(bitmap);  
     });
