It's my MySql DB
其编码:-
public String convertBitmapToString(Bitmap bmp) {
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, stream); //compress to which format you want.
byte[] byte_arr = stream.toByteArray();
String imageStr = Base64.encodeToString(byte_arr, 1);
return imageStr;
}
这是解码:-
String img=o.toString();
byte[] imageAsBytes = Base64.decode(img.getBytes(), Base64.DEFAULT);
imageView.setImageBitmap(BitmapFactory.decodeByteArray(imageAsBytes, 0, imageAsBytes.length));
谢谢。
最佳答案
可以通过
private String getBase64String() {
// give your image file url in mCurrentPhotoPath
Bitmap bitmap = BitmapFactory.decodeFile(mCurrentPhotoPath);
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
// In case you want to compress your image, here it's at 40%
bitmap.compress(Bitmap.CompressFormat.JPEG, 40, byteArrayOutputStream);
byte[] byteArray = byteArrayOutputStream.toByteArray();
return Base64.encodeToString(byteArray, Base64.DEFAULT);
}
对于解码
private void decodeBase64AndSetImage(String completeImageData, ImageView imageView) {
// Incase you're storing into aws or other places where we have extension stored in the starting.
String imageDataBytes = completeImageData.substring(completeImageData.indexOf(",")+1);
InputStream stream = new ByteArrayInputStream(Base64.decode(imageDataBytes.getBytes(), Base64.DEFAULT));
Bitmap bitmap = BitmapFactory.decodeStream(stream);
imageView.setImageBitmap(bitmap);
}
