Here my code :-

1. Button click event for open gallery :-

   btn?.setOnClickListener(object : View.OnClickListener { override fun onClick(arg0: View) {

           val i = Intent(
                   Intent.ACTION_PICK,
                   android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
   
           startActivityForResult(i, RESULT_LOAD_IMAGE)
       }
   })
   

2. This for use display image in Imageview:-

   override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) { super.onActivityResult(requestCode, resultCode, data)

   if (requestCode == RESULT_LOAD_IMAGE && resultCode == Activity.RESULT_OK && null != data) {
       val selectedImage = data.data
       val filePathColumn = arrayOf(MediaStore.Images.Media.DATA)
   
       val cursor = contentResolver.query(selectedImage!!,
               filePathColumn, null, null, null)
       cursor!!.moveToFirst()
   
       val columnIndex = cursor.getColumnIndex(filePathColumn[0])
       val picturePath = cursor.getString(columnIndex)
       cursor.close()
   
       val imageView = findViewById(R.id.imageView) as ImageView
       imageView.setImageBitmap(BitmapFactory.decodeFile("file://" + picturePath))
   
   }
   

   }

Answer 1

There is no requirement for your query() to return a filesystem path that you can use.

Instead, pass your Uri to your favorite image-loading library (Glide, Picasso, etc.). They can load the image into your ImageView, doing all of the I/O on a background thread.
