Set a bitmap image in ImageView

Question

I've tried this

try {
        byte[] decodedString = Base64.decode(repPlus, Base64.URL_SAFE);
        Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
        holder.imageView.setImageBitmap(decodedByte);
    } catch (Exception e) {
        Log.d("Error: ", e.getMessage());
    }

And it returns an error:

bad base-64

And then I've tried this Bad base-64 error. And it removes the error. And Base64 to Bitmap to display in ImageView for decoding a base64 String

try {
        String repSlash = product.getImage().replace("/", "_");
        String repPlus = repSlash.replace("+", "-");
        byte[] decodedString = Base64.decode(repPlus, Base64.URL_SAFE);
        Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
        holder.imageView.setImageBitmap(decodedByte);
    } catch (Exception e) {
        Log.d("Error: ", e.getMessage());
    }

But the image does not views in the application.

Try doing this after initializing the Bitmap decodedByte

BitmapDrawable drawable = new BitmapDrawable(getResources(), decodedByte);
holder.imageView.setBackgroundDrawable(drawable);

EDIT: Try this:

String base64Image = product.getImage().split(",")[1];

byte[] decodedString = Base64.decode(base64Image, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);

holder.imageView.setImageBitmap(decodedByte);

Hope this helped!

I got a problem with getResources(). I'm in an adapter class. Is this okay? – Mark Joshua Fajardo Jul 02 '18 at 06:16
Then add a Context variable to the Adapter constructor, and then do like, `BitmapDrawable drawable = new BitmapDrawable(context.getResources(), decodedByte);` – Thawindu Angesh Tuto Jul 02 '18 at 06:28
I'll post again if I find a solution – Thawindu Angesh Tuto Jul 02 '18 at 06:51
@MikaelFaire Can you recheck your _Base64 String_ because if you're doing the conversion right, this should work. And further, check if the _holder.imageview_ is set up clearly. – Thawindu Angesh Tuto Jul 02 '18 at 07:25
My base64 string is like this "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD/2wCE.............." – Mark Joshua Fajardo Jul 02 '18 at 07:43
I used the imageview by using images in drawable. But by using this data from mysql, using php and json it does not view the image. – Mark Joshua Fajardo Jul 02 '18 at 07:45
@MikaelFaire Try the updated version. That should work. Or, I think you should recheck the **ImageView**. – Thawindu Angesh Tuto Jul 02 '18 at 07:56
