Ich habe Code, um Bild und Text auf den Server zu laden, aber mein Code codiert das Bild und auf dem Server sollte das Bild entschlüsselt werden.verhindern Bildcodierung in Java
Ich möchte Bildcodierung verhindern. Ich habe einige Wege ausprobiert, aber sie funktionieren nicht.
Ich weiß nicht, wie das geht. Bitte hilf mir.
Hier ist mein Code:
public class Share_food extends Activity {
ProgressDialog prgDialog;
String encodedString;
RequestParams params = new RequestParams();
String imgPath, fileName;
Bitmap bitmap;
private static int RESULT_LOAD_IMG = 1;
EditText ti,desc;
TextView tv;
String url="http://example.com/index.php";
@SuppressLint("CutPasteId")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.share_food);
prgDialog = new ProgressDialog(this);
prgDialog.setCancelable(false);
ti= (EditText)findViewById(R.id.title);
desc=(EditText)findViewById(R.id.share_desc22);
//getActionBar().setBackgroundDrawable(new ColorDrawable(Color.parseColor("#3b5998")));
//getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));
//getActionBar().setTitle("");
}
public void loadImagefromGallery(View view) {
Intent galleryIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(galleryIntent, RESULT_LOAD_IMG);
}
@Override

super.onActivityResult(requestCode, resultCode, data);

if (requestCode == RESULT_LOAD_IMG && 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();
ImageView imgView = (ImageView) findViewById(R.id.imgView);
imgView.setImageBitmap(BitmapFactory
.decodeFile(imgPath));
String fileNameSegments[] = imgPath.split("/");
fileName = fileNameSegments[fileNameSegments.length - 1];
params.put("filename", fileName);

Toast.LENGTH_LONG).show();

}

}
}
