ImageView içinde dataUrl yüklemek için bir yol var?

Answer 1

İlk olarak Bitmap'e convert the Base64 encoded string gerekir.

ImageView imageView; 
imageView = (ImageView) findViewById(R.id.image_view); 
imageView.setImageBitmap(bitmap); 

: Başka bitmaple olduğu gibi Sonra sadece yapmak

byte[] decodedString = Base64.decode("Your Base64 String", Base64.DEFAULT); 
Bitmap bitMap = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 

o bitmap senin imageViewR.id.image_view olarak tanımlanır varsayarsak içinde size bit eşlem sahip yapılır: Kod bağlantılı sorudan aşağıda pasajı

Answer 2

Yalnızca bir bayt dizisi almak için Base64.decode() yöntemini kullanarak Base64 görüntü kodlamasını çöz ve BitmapFactory.decodeByteArray() yöntemini kullanarak Bitmap'u oluşturun.

Answer 3

Girdinin Base64 bölümünü alırsanız, bu yolla kolayca bir Bitmap'e dönüştürülebilir:

byte[] decodedString = Base64.decode("your base64 string", Base64.DEFAULT); 
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 

Answer 4

String değişkeni şifresini çözmek

Yaylı encodedImage base64 dize almak, bu dize // set base64 dize değeri byte [] decodedString = Base64.decode (encodedImage, Base64.DEFAULT); Bitmap decodedByte = BitmapFactory.decodeByteArray (decodedString, 0, decodedString.length);
