Users save three data: name, note and image. As you can see the code below, I succeeded to code to send the name and note to the server side. But, I have no idea how to send a selected image file from the device to the serverDB.
public class AddEditWishlists extends Activity {
// Client-Server - Start //////////////////////
// Progress Dialog
private ProgressDialog pDialog;
JSONParser jsonParser = new JSONParser();

// JSON Node names

byte[] image=null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.add_wishlist);
setUpViews();
}
private void setUpViews() {
inputname = (EditText) findViewById(R.id.inputname);
inputnote = (EditText) findViewById(R.id.inputnote);
inputphoto = (ImageView) findViewById(R.id.inputphoto);
Bundle extras = getIntent().getExtras();
if (extras != null) {
id=extras.getInt("id");
inputname.setText(extras.getString("name"));
inputnote.setText(extras.getString("note"));
image = extras.getByteArray("blob");
if (image != null) {
if (image.length > 3) {
inputphoto.setImageBitmap(BitmapFactory.decodeByteArray(image,0,image.length));
}
}
}
//Image Upload Button
upload = (Button) findViewById(R.id.upload);
upload.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.setType("image/*");
startActivityForResult(intent, 0);
}
});
// Save the data
save = (Button) findViewById(R.id.save);
// Save하면 발생되는 이벤트
save.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (inputname.getText().length() != 0) {
AsyncTask<Object, Object, Object> saveContactTask = new AsyncTask<Object, Object, Object>() {
@Override
protected Object doInBackground(Object... params) {
saveContact();

return null;
}
@Override
protected void onPostExecute(Object result) {
finish();
}
};
saveContactTask.execute((Object[]) null);
} else {
AlertDialog.Builder alert = new AlertDialog.Builder(
AddEditWishlists.this);
alert.setTitle("Error In Save Wish List");
alert.setMessage("You need to Enter Name of the Product");
alert.setPositiveButton("OK", null);
alert.show();
}
}
});
}
// If users save data, this will act (data -> db)
private void saveContact() {
if(yourSelectedImage!=null){
ByteArrayOutputStream outStr = new ByteArrayOutputStream();
yourSelectedImage.compress(CompressFormat.JPEG, 100, outStr);
blob = outStr.toByteArray();
}
else{blob=image;}
// Change Text type to string type to save in the DB
SQLiteConnector sqlCon = new SQLiteConnector(this);
if (getIntent().getExtras() == null) {
sqlCon.insertWishlist(inputname.getText().toString(), inputnote.getText().toString(), blob);
}
else {
sqlCon.updateWishlist(id, inputname.getText().toString(), inputnote.getText().toString(),blob);
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode,Intent resultdata) {
super.onActivityResult(requestCode, resultCode, resultdata);
switch (requestCode) {
case 0:
if (resultCode == RESULT_OK) {
Uri selectedImage = resultdata.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String filePath = cursor.getString(columnIndex);
cursor.close();
// Convert file path into bitmap image using below line.
yourSelectedImage = BitmapFactory.decodeFile(filePath);
inputphoto.setImageBitmap(yourSelectedImage);
}
}
}
}
How can I code between the client-server annotation to send the image file?..
