我的Base64字符串是从照片转换而来的。我尝试将它们放在我的json对象中,但它会导致部分Base64字符串被剪切,甚至其他json对象也会消失。当我用短的Base64字符串替换原来的那个时,json格式就可以了。我怎么能修好它?
public void TakePhotoOnClick(View view) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
file = Environment
.getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES);
file = new File(file, "picture.jpg");
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(file));
if (isIntentAvailable(this, cameraIntent)) {
startActivityForResult(cameraIntent, REQUEST_TAKE_PICTURE);
} else {
Toast.makeText(this, R.string.msg_NoCameraAppsFound,
Toast.LENGTH_SHORT).show();
}
}
private boolean isIntentAvailable(Context context, Intent intent) {
PackageManager packageManager = context.getPackageManager();
List<ResolveInfo> list = packageManager.queryIntentActivities(intent,
PackageManager.MATCH_DEFAULT_ONLY);
return list.size() > 0;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.w(" MainActivity","onActivityResult");
if (requestCode == REQUEST_TAKE_PICTURE && resultCode == RESULT_OK) {
Bitmap picture = BitmapFactory.decodeFile(file.getPath());
ivDriverPhoto.setImageBitmap(picture);
ByteArrayOutputStream out1 = new ByteArrayOutputStream();
picture.compress(Bitmap.CompressFormat.JPEG, 50, out1);
image = out1.toByteArray();
driver_photo = Base64.encodeToString(image, Base64.DEFAULT);
Log.w(" MainActivity","image"+ driver_photo );
}
}
照片Base64字符串类似于以下字符串: 图像/ 9J / 4AAQSkZJRgABAQAAAQABAAD / 2wBDABALDA4MChAODQ4SERATGCgaGBYWGDEjJR0oOjM9 ... (它完全显示它太长了。)
短测试Base64 Sting如下: 图像/ PNG; BASE64,iVBORw0KGgoAAAANSUhEUgAAABAAAAAQCAQAAAC1 + jfqAAAAAnNCSVQICFXsRgQAAAAJcEhZcwAAAHoAAAB6AZUMqX8AAAAZdEVYdFNvZnR3YXJlAHd3dy5pbmtzY2FwZS5vcmeb7jwaAAAA4ElEQVQoz6XRzyvDcRgH8JdJObmsJMUf4KIotaJEUYrLNPnxTY4r3Ocw32K + HwpxmZ1cNH / C / rzHYVvNZQ56X1 / P09P7EcbHn0AmH5OMYux8QQqmXSk8K8yasCWX2zMZpD44txSCDccOVZVsaqiPgm + v2roqntxpq / n0oTQEy05CcGnem1YIrnSUByDIzVlwY1FNS + bIix1rww3beh4kPR119y6cSs40JJIDTeuaCquSjtsQXHu32wePSkHZTNA0paFqX2FCkij6VwyKyUOwohKCpCDTHan261fRXZl / F / MHNSqo8Xq9umsAAAAASUVORK5CYII =

我通过使用BitmapFactory来减少图片大小来解决问题,而Base64字符串足够短以放入json。
