** 我可以使用这段代码将图像保存在远程Mysql数据库中。但是我无法从这段代码中获得完整的图像质量。图像的质量非常差。有人建议使用它的解决方案吗?
提前致谢。 **

尝试以下代码:
sklearn
<强> encodeImagetoString()
if (requestCode == SELECT_FILE && resultCode == RESULT_OK
&& null != data) {
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
imgPath = cursor.getString(columnIndex);
cursor.close();
}else if (requestCode == REQUEST_CAMERA && resultCode == RESULT_OK ) {
imgPath = fileUri.getPath();
if (imgPath != null && !imgPath.isEmpty()) {
encodeImagetoString();
} else {
Toast.makeText(getApplicationContext(), getResources().getString(R.string.some_error_occured),
Toast.LENGTH_LONG).show();
}
}
希望它会对你有所帮助。

而不是使用
photo.compress(Bitmap.CompressFormat.JPEG, 90, stream);
尝试使用
photo.compress(Bitmap.CompressFormat.JPEG, 100, stream);
