Android基地64編碼字符串不顯示實際圖像

您好，我正在通過基地64編碼和解碼與Android圖像處理。我需要發送一個編碼的基地64字符串到服務器作爲一個字符串。當我在android系統側試了一下，我可以把它解碼成原始image.and我的解碼和編碼如下Android基地64編碼字符串不顯示實際圖像

public void base(Bitmap bitmap) 
    { 
     ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream(); 
     bitmap.compress(Bitmap.CompressFormat.PNG, 100, byteArrayOutputStream); 
     byte[] byteArray = byteArrayOutputStream .toByteArray(); 
     String encoded = Base64.encodeToString(byteArray, Base64.DEFAULT); 
     toimag(encoded); 
     String a=encoded.replaceAll("\\s+",""); 
     Log.i("strrr",a); 
    } 

    public void toimag(String encodedImage) 
    { 
     byte[] decodedString = Base64.decode(encodedImage, Base64.DEFAULT); 
     Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 
     logo.setImageBitmap(decodedByte); 
    }

，但我不能抽到使用http://www.askapache.com/online-tools/base64-image-converter/實際圖像。它只顯示我的實際圖像的一部分。這是我的基地64字符串

我該如何解決這個問題？這個編碼字符串有問題嗎？請幫忙。在此先感謝:)

你在做什麼'字符串A = encoded.replaceAll（「\\ S +」，「」） ;'？ –

這是用於testing.remove所有空格。我沒有使用該字符串 – UserAndroid

你從來沒有解釋過這個問題。清楚地說明你的意圖 –

看來你是從logcat中剪切和粘貼。 logcat會截斷長消息，因此您不應該依賴它來複制大量數據。您應該將base64字符串保存到文件中，然後嘗試使用該文件進行驗證。

hello。某些設備不允許寫入文件。我使用Q-mobile測試寫入文件，然後搜索許多許多帖子，但無法在設備中創建文本文件（內部存儲） – kemdo

對於圖像編碼爲Base64

ByteArrayOutputStream baos = new ByteArrayOutputStream(); 
bitmap.compress(Bitmap.CompressFormat.PNG, 100, baos); 
byte[] b = baos.toByteArray(); 
String imageEncode = Base64.encodeToString(b, 
Base64.DEFAULT);

對於解碼圖像

byte[] decodedByte = Base64.decode(imageEncode, 0); 
Bitmap newBitmap = BitmapFactory.decodeByteArray(decodedByte, 0, decodedByte.length); 
logo.setImageBitmap(newBitmap);
