Bitmap对图像进行Base64编解码

1. public String bitmaptoString(Bitmap bitmap) {
2. // 将Bitmap转换成字符串
3. String string = null;
4. ByteArrayOutputStream bStream = new ByteArrayOutputStream();
5. bitmap.compress(CompressFormat.PNG, 100, bStream);
6. byte[] bytes = bStream.toByteArray();
7. string = Base64.encodeToString(bytes, Base64.DEFAULT);
8. return string;
9. }

1. public Bitmap stringtoBitmap(String string) {
2. // 将字符串转换成Bitmap类型
3. Bitmap bitmap = null;
4. try {
5. byte[] bitmapArray;
6. bitmapArray = Base64.decode(string, Base64.DEFAULT);
7. bitmap = BitmapFactory.decodeByteArray(bitmapArray, 0,
8. bitmapArray.length);
9. } catch (Exception e) {
10. e.printStackTrace();
11. }
12. return bitmap;
13. }
