如何在ImageView中显示压缩图像并显示其大小? [英] How do I display the Compressed image in ImageView and display its Size?

问题描述

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
                ContentResolver resolver = getContentResolver();
                ContentValues contentValues = new ContentValues();
                contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, "Image" + timestamp + ".jpg");
                contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/*");
                contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_PICTURES + File.separator + "Compressed_Images");
                imageUri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
    
            

fos = resolver.openOutputStream(Objects.requireNonNull(imageUri));
bitmap.compress(WEBP_LOSSY, 10, fos);
            Objects.requireNonNull(fos);

让它显示在imageview中------>

Got it displayed in imageview------>

 InputStream is = getContentResolver().openInputStream(imageUri);
                Bitmap bitmap1 = BitmapFactory.decodeStream(is);
                compImage.setImageBitmap(bitmap1);

它压缩并保存图像没有问题

Its Compressing and saving the Image No issue in that

推荐答案

 InputStream is = getContentResolver().openInputStream(imageUri);
            Bitmap bitmap1 = BitmapFactory.decodeStream(is);
            compImage.setImageBitmap(bitmap1);

好的....我设法在Imageview中设置了图像(希望它是压缩图像)现在我如何得到它的大小?

Okay....I was managed to set image in Imageview(I hope its Compressed image) Now how do I get the size of this?
