You should be able to use BitmapFactory:

File mSaveBit; // Your image file
String filePath = mSaveBit.getPath();  
Bitmap bitmap = BitmapFactory.decodeFile(filePath);
mImageView.setImageBitmap(bitmap);

  1. Define File

    String fileName = "/myImage.jpg";
    File file = new File(fileName); 
    
  2. get Bitmap of Image

    Bitmap bitmap = BitmapFactory.decodeFile(file.getAbsolutePath());
    
  3. Set Bitmap to ImageView

    myImageView.setImageBitmap(bitmap);
    

You can use this function to get Bitmap from file path

fun getBitmap(filePath:String):Bitmap?{
    var bitmap:Bitmap?=null
    try{
        var f:File = File(path)
        var options = BitmapFactory.Options()
        options.inPreferredConfig = Bitmap.Config.ARGB_8888
        bitmap = BitmapFactory.decodeStream(FileInputStream(f),null,options)
    }catch (e:Exception){

    }
    return bitmap
}
