// url to create new product // you have to create php file to connect with server and below url is just example

private static String url_create_product = "http://10.0.2.2/html/atm_database`/customers.php"; 

// Edit Text

edittext= (EditText) findViewById(R.id.input1); edittext= (EditText) findViewById(R.id.input2); 

// Create button

 Button sub = (Button) findViewById(R.id.submit); sub.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { // write code here to get data from edittext // creating new product in background thread new CreateNewProduct().execute(); } }); } 

/** * Background Async Task to Create new product * */

class CreateNewProduct extends AsyncTask<String, String,String> { /** * Before starting background thread Show Progress Dialog * */ protected void onPreExecute() { super.onPreExecute(); pDialog = new ProgressDialog(Ac1.this); pDialog.setMessage("Please wait.."); pDialog.setIndeterminate(false); pDialog.setCancelable(true); pDialog.show(); } /** * Log in * */ protected String doInBackground(String... args) { // Building Parameters List<NameValuePair> params = new ArrayList<NameValuePair>();//namevaluepair is a class in apachae for setting name-val parameter params.add(new BasicNameValuePair("id", data1);//BasicNameValuePair is a subclass of NameValuePair is data you have to server params.add(new BasicNameValuePair("pass",data2)); // getting JSON Object // Note that create product url accepts POST method JSONObject json = jsonParser.makeHttpRequest(url_create_product, "POST", params); // check log cat fro response // Log.d("Create Response", json.toString()); // check for success tag try { int success = json.getInt(TAG_SUCCESS); String cust_name=json.getString("name"); String sessid=json.getString("id"); if (success == 1) { // successfully created product //write code to do things getting response from server } else { Log.w("else", "wrong id"); runOnUiThread(new Runnable() { public void run() { Toast.makeText(Ac1.this, "Wrong ID or Password!!", Toast.LENGTH_LONG).show(); } }); } } catch (JSONException e) { e.printStackTrace(); } return null; } /** * After completing background task Dismiss the progress dialog * **/ protected void onPostExecute(String file_url) { // dismiss the dialog once done pDialog.dismiss(); } }
