Android How to change String with Edittext and reuse in same activity
I have a serious problem, I have a card swiper app that passes all of card data threw a xml (the way the xml is structured in my code was writted by the sdk provider). I need to make it possible to do a manual entry using 2 EditText (1 for Card number and 1 for ExpDate) and then pass that data to the same Activity (OR A NEW Activity) to be used in the xml that processes the order. Can this be done? How can this be done? Below is my Code - and edits or corrections will be very helpful ... Thank you in advance.
String tranXmlFmt =
"<?xml version=\"1.0\"?><TStream>"
+ "<Transaction>"
+ "<IpAddress>66.173.160.125</IpAddress>"
+ "<MerchantID>002649</MerchantID> "
+ "<OperatorID>50</OperatorID>"
+ "<TranType>Credit</TranType>"
+ "<CardType>VISA</CardType> "
+ "<TranCode>Sale</TranCode> "
+ "<OperatorID>55</OperatorID> "
+ "<InvoiceNo>100001</InvoiceNo>"
+ " <RefNo>100001</RefNo> "
+ "<PartialAuth>Allow</PartialAuth>"
+ "<Account>"
+ "<AcctNo>4104891389583005</AcctNo>"
+ "</Account> "
+ "<ExpDate>0214</ExpDate>"
+ "<Amount><Purchase>13.00</Purchase></Amount>"
+ "<UserTraceData>GBTE130116</UserTraceData>"
+ "</Transaction> "
+ "</TStream>";
String initXml = ""
+ "<?xml version=\"1.0\"?>"
+ "<TStream><Admin>"
+ " <MerchantID>002649</MerchantID>"
+ " <TerminalID>002</TerminalID><TranCode>SecureDeviceInit</TranCode>"
+ " <PadType>None</PadType>" + " <TranType>Setup</TranType>"
+ " <SecureDevice>UniMagSecureMagDsi</SecureDevice>"
+ " <ComPort>1</ComPort>"
+ " </Admin>"
+ "</TStream>";

I just need to add 2 Edittext and change the AcctNo and ExpDate STRING to be used in this same activity. please any help will be greatful.
Solution
You can get data from edittext and pass it to your secondactivtiy using intents.
String s1,s2
EditText ed1= (EditText)findViewById(R.id.editext);
EditText ed2= (EditText)findViewById(R.id.editext2);
on Button click
s1 = ed1.getText().toString();
s2 = ed2.getText().toString();
ed1.setText("");
ed2.setText("");
In same activity. Can keep other tags as above.
String xml ="<AcctNo>"+s1+"</AcctNo>"
+ "<ExpDate>"+s2+"</ExpDate>";
OR
Intent i= new Intent("com.example.secondactivity");
i.putExtra("key1",s1);
i.putExtra("key2",s2);
startActivity(i);
In Second Activity you can retrieve the values.
String value1,value2;
Bundle extras = getIntent().getExtras();
if (extras != null) {
value1 = extras.getString("key1");
value2 = extras.getString("key2");
}
Can keep other tags as above.
String xml ="<AcctNo>"+value1+"</AcctNo>"
+ "<ExpDate>"+value2+"</ExpDate>";

System.out.println("................"+xml);
tv3.setText(xml);
ed1.setText("");
ed2.setText("");
}
});
}
}
As you can see it works. See the snap shot. I have 3 text views, 2 editext's and a button. After user types in editext's i click the button and i set the values to textview. As you can see the values reflects in string xml which is the result set in textview3.
